Despite that limitation, your ships all look very good, neat and clean. I assume you mean that very small pieces and details are difficult. Have you tried a magnifying headset like the Carson one below? I like it because you can wear your normal glasses underneath them and just flip down the magnifying lenses when you need them. I've been using mine for several months now and really like how well they work, and the LED light on top works well too.

Ok I had to look that up and yes in fact "semester" in Swedish means "holiday". Swedish students going to college in the US must have an amusing time scheduling brutal classes for their first and second "holidays" each year -
For anyone who wants the same look AND is lucky enough to live in the land of milk and honey and low shipping costs, 3/4" x 3/4" x 5" Amboyna burl pen blank for $10.19. As mentioned I suggest making that a single handle rather than two unless your scroll saw/saw frame can easily handle making straight cuts in this. They also have some nice-looking options in coolibah burl and malee burl and (I've never heard of any of these BTW, you definitely want to wear dust protection) thuya burl along with more standard burl woods. All $10.19 per blank. Coolibah, Malee, Thuya in order.

Worse than the pushrods- those could be fixed without too much pain- are the exhausts. In the 9J they go to the back half of the crankcase, and I think the 9j has a larger-diameter crankcase too that provides a bit more room for the exhaust, and to make those you need to make a blank with baking clay and then carve it down into a master for casting. Much better plan to wait and get a real 110. -
Looks good Danny. One thing I haven't seen yet, and something I want to do, is a waterline with a realistic suction wave- I'd like to do WWI BCs at flank speed, I have a pic of Vonn der Tann at speed and the suction trough/wave from the props is really significant, 100k+ shp could move serious masses of water. To do it right you'd have to establish that wave first, and in the case of VdT the low point is at least several feet below the lwl, and then do a water modeling process like you've done over top of that - that wave really doesn't seem to alter the surrounding water state much.

Distort is one of the transform modes in Photoshop but the one Dan should have used, and you should look for in GIMP, is Perspective. That mode is designed to do exactly what you're trying to do here. I also like the dueling SR stern drawings with HH and Cedric's profile images

On the up side, I got to say "I'd have to get on a plane for a funeral in Australia for a guy I killed with a funny knife joke", so I think it's a wash Ms. Takita is not just well looked after, she is maintained in a totally spoiled bubble of perfect catness. I think she has four different heated beds now, not to mention the fireplace we turn on most evenings. If she's not in one of her beds a couple feet away, she's in my lap. At night she sleeps under the blankets of the bed, apparently unaware that cats don't do that.

The evil Jay who sits on my shoulder suggesting funny but wrong things to do had a great idea - the day after I finish these knives, post that I tried them for a few minutes, decided I didn't like them, and am going back to my old knife. If I could then have a webcam capture the expression on Rick's face I think it would be good for at least a solid 30 minutes of laughing. But then I decided he might actually stroke out and then his admiral would be understandably annoyed with me and I'd have to get on a plane for a funeral in Australia for a guy I killed with a funny knife joke, and I decided it was probably not a good idea. I'll just have to keep myself happy giggling imagining that expression So one knife done, other just has a bit more to go that I'll finish tomorrow. As alluded to in the last update, these were going to get my normal brass counterweight, it adds mass that I like and it moves the balance point to more or less the center of the knife, which I also prefer. And yes you need a lathe and basic metal lathe tools and knowledge, but otherwise these are Basic Metal Lathe Work, Chapter 1 level simple. It's not worth setting up the cross slide to do the taper, so I do them with files and sandpaper and the Mk.I Eyeball measuring system. You need a facing tool to face off the ends, otherwise the rest of the operations are all done with the parting tool you see here. Two reveals that I again do by eye, and I don't even measure the width of the shaft that goes into the handle, I eyeball more or less 1/8". This time I was +/- .005" for the two of them. The reveals should have a shiny finish from the parting tool, the rest I finish with 1200 grit sandpaper to give it a considerably duller finish, the contrast is nice. It's not very noticeable when they're brand new but after given a chance to oxidize a bit it looks good, or at least I think so. As these knives are tricky to drill on my small mill, I drilled the required holes by hand with pin vises. Like files, there is no such thing as too many pin vises. Another good example of where my giant pile of tools in many cases is just adding a bit of speed by for example having several pin vises each with a different chuck so I never have to stop and do that switching process again. I put three increasing diameter drills in the pin vises and drilled the normal way by doing say three turns looking at the piece from one orientation, ensuring the bit is aligned with the knife axis, and then rotating the knife handle 90 degrees and doing three turns, etc., you can drill holes very accurately that way. Final size was set by a small mill in my rotary tool, we need close here not a press fit. Here's what they will look like mounted. Let's go over the advantages of a CA finish for tool handles again: It is the most crystal-clear finish I am aware of, perfect for highly figured woods. It provides a better grip than any finish I am aware of, including bare wood. And the shinier it gets the better the grip gets, opposite of what you see with most finishes. It is the hardest finish I am aware of. Rap a knife handle like these on the edge of your bench and it's the edge of your bench that will come out the loser. When you spill super glue all over it you're just refreshing the finish You can start, apply multiple coats, sand, polish, run around in the street naked while pouring mustard over your head and be back inside hiding behind a shower curtain while the admiral pretends to know nothing when the cops show up, and STILL be done in two hours with a knife you could use right then and there. Show me another finish where two hours is not replaced by two days, at LEAST. Disadvantages: Difficult to apply on anything much bigger than a tool handle. Easily the worst-leveling finish in existence. You HAVE to sand between coats and do so quickly while the finish isn't fully cured. Any coat you apply needs to be fully sanded before you can do anything else. If you let it fully cure before you level-sand it, you're going to have oodles of fun getting it level. Comparatively very expensive, making it not worth it from a cost perspective also to use on anything bigger than a tool handle. It's not perfect, but the disadvantages can be managed and I use it for all tool handles now, I don't see anything else as competitive. And cost can be very much controlled by the process you follow. Here is my sophisticated setup. I'm using nothing but thin CA here, and it's important you do so for the first coat at least, which is more of a soaking. The 8oz of thin CA here was $21 from Amazon, and I will use < 5% for these two handles- I fill the tube/bath, do the soaks/coats, and then pour the remainder into the bottle. I've found no negative effects on the glue in doing so. So I could make another 30 knives minimum from this bottle if needed. If you're concerned about buying that much volume, I've had much success making it last longer by storing it in the refrigerator, just let it reach room temp before use. I tape on dowels to suspend the knife handle in the bath and keep it balanced, don't want it touching the metal as it can trigger local setting. For the first coat, as mentioned it's a soak. I left these in there for an hour each, the thin CA penetrates as deeply as possible and you turn much of it into a composite material. For the later coats - you really shouldn't need more than one soak and two coats - you just dip and remove. This is the tricky part, getting rid of the excess glue and then doing everything possible to keep the coat as even as possible and not pooling anywhere while it sets. I put a nice big double piece of foil down, and when I pull it off I shake it straight downward and touch the tail down to the foil a few times in an effort to get the excess off. As SOON as I think I have removed as much as I can/want, I level the handle's long axis with the horizon and then starting turning it constantly along that axis like a mini slow-roaster. And I keep turning it until the surface is fully set. For the soak coat, the turning while waiting to set can take quite a while - 15 minutes or more. For the coats it acts more like thin CA and will set within a minute or two. This is what it will look like after the current coat is set, you can see it's none too level. You definitely don't want to put on multiple coats without sanding fully level between coats. BTW, I am using 400 grit for the level sanding between coats. Another issue is that while it's relatively easy to sand the overall handle level, glue will build up around the handle/blade joint, and you really really don't want to let that fully cure before you deal with it. Here you can see I'm in the process of trimming that back, using the first knife I made, an xacto replacement. This is what disposable blades are for, cutting through nasty glue You can also see what the surface looks like after sanding, this one has been fully level-sanded before working on the glue buildup. And this is Ms. Takita, who closely monitors all my activities so she always knows exactly how much she needs to disapprove of them. This is the electrically-warmed bed that sits on one of the tool chests of drawers right next to my workbench, where she has a good view of everything noisy and annoying that she needs to disapprove of. And the bed is close enough to where I sit to demand regular ear scratches to make up for all of the bad things I am doing. Here is the second knife getting ready to go in for his initial soaking. Since the wood is so nice here, the handles are sanded out to 2000 grit before getting their finish. Once we have our three coats and everything is level sanded with 400 grit, we're ready to finalize the finish. I work my way up through the grits again to 2000 grit. Then it's time for the final polish, I'm using Novus plastic polish #2. There are a couple hundred ways to polish something like this, I use Novus because it works very well on CA, you can get it about anywhere, and it's not super-expensive at least compared to some other options. You can use a cloth and do it by hand easily enough, and with a rotary tool the most common thing to use is felt points. I am using these floppy polishing disks as it makes me let the polish do the work. As you see I apply the polish to the handle, not the disk. You can do it the other way around, but if so I recommend full face coverage and not wearing any clothes you like Also I'm running down at like 5-6k rpm, the only thing accomplished by going faster is creating a mess. And after only 5-10min of polishing, we have a final finish Go ahead and look at the full-sized version here, you should be able to see why the wood was sanded out to a polish before adding the finish, I'm not aware of anything that shows off figured wood better than this. I used a cutoff wheel to cut some notches into the brass tailpiece shaft to give the glue a mechanical hold as well as the adhesive hold. And we have a new knife. His brother will join him tomorrow and we can start working on ships again!

Woohoo! The answer is carefully! (ducks) Take a look here. I pinged them to see what AU shipping rates would be, here it's free shipping. They seem to carry a pretty large range of mid-price Japanese carving tools, which means like the ones I bought the steel will be very good but you may need to do some reshaping of bevels and flattening backs etc. Look at this specifically. If you look at the people who viewed this also viewed list you'll see they have a series of knives like this, from mid-length to pencil handles with blades of varying shape and length, find the one(s) that work best for you. Best case you have at least three, one with the cutting edge aligned to the handle's long axis (straight blade) a skew like your marking knife, and something that faces more or less forward. The best I think is curved edge with tip almost facing pure forward, but keep in mind that sharpening curved edges is considerably trickier than straight edges. There are at least a half-dozen basic ways to sharpen knives in terms of the kinds of stones. The performance/cost sweet spot IMO is Japanese water stones, good quality stones can be had for not much.

I was just thinking that Popeye could probably make an awesome steampunk clipper. No really, that would be awesome. We just need to explain what steampunk is I think the best simple explanation though is imagine that H.G. Wells thought up jet engines and all sorts of powerful machines (that would be powered by steam, since those were the engines of his time) and flying vehicles and what they would look like and how they would work if that were the case. Re-imagine what followed Victorian/Edwardian England if Nautilus became the pattern for an amazing range of new machines. Generally good fun right up to the point where they start taking themselves a tad too seriously, but that could be said about almost anyone. Including ship modelers

And one more before I go try to finish these, remember a goodly portion of the ooh ah factor here is just the wood, and buying a nice piece of wood requires no skill If you have a local Woodcraft store or a lumber supply place that carries supplies for wood turners and especially pen turners, stop by semi-regularly and poke around what they have. Even the most stringent admirals generally don't complain about buying a $5 piece of wood that will make a very nice knife. This is as expensive as it gets, snakewood. Very dramatic, $10 for one piece. Although I made two handles out of one blank I wouldn't recommend trying that unless you have a very good scroll saw, you need to cut it with the thinness of a scroll saw blade if you're going to get enough material. Here's cocobolo and you get 5 pieces for $10. A total of $2 per knife handle or $1 if you quarter it like I did. Really, the wood cost is very little, so no excuse for not having your own knives have really nice handles

Oh also, I should have remembered to clearly explain that the only reason the holes are really necessary is if you have the blade top line be the same as the handle top line, giving you an open-topped rabbet/mortise for the blades. When you do that the handle wood isn't going to provide meaningful resistance to the torsion moment it feels during cutting, so you run these pins through and through to provide the necessary retention. If you have handle wood on both sides of the blade, there is no need for the pins and you can make a knife with a blade like these with none of that hassle. I just prefer the point to be dead on the handle top line, I think that helps me locate the point more easily, but it's hardly required. Here are some examples of no-pins buried-blade knives with very simple handles to make.

Both Popeye and Rick were ahead of us already Popeye's point about some of them being good paint applicators and some leaving bubbles is worth remembering, and it might make a difference depending on the viscosity of the paint/ink. So my purchase of the 100 cheaper ones may not have been a great idea. Popeye, I promise to be careful, but remember these are not the first but like the 27th and 28th lethally sharp knives I own I also prefer it when they bite you a little early, the ones that make me nervous are the ones that are saving it up for one big shot. Thanks Sam. Yes a transfer punch would have worked great had the holes in the blade gone all the way through as they usually do, that would be the right way to mark the hole locations on the handles for a normal blade. But here they only went 3/4 through as I drilled them but didn't have anything that could have drilled through the Rc63 layer on the back side of each blade, so I had to get creative to figure out a way to transfer them. What I should have done is been a tad more patient and sent a drawing to Ron Hock as to what I wanted, he does custom work at very reasonable cost. That's what I did for my wenge knife among others, I recall the blade for that knife was just $25 or $30, but I did have to wait a couple weeks. And it was one small blade instead of effectively the two I got out of each of those $22 marking knives. I'd recommend anyone wanting to make knives similar to the above who are not cost-limited to do the same and contact Ron at Hocktools.com with a clear drawing with measurements of what you need, he will quickly respond with a price. With nice normal through holes, the only tricky part is the rabbets. If you have a mill or a Dremel router base similar to mine, no problem, very easy to do. But you can also do it accurately with a knife and/or paring chisel if you're good with those tools, that's how they used to do it. I should draw something here, there's a three-step process to doing something that like quickly and accurately with a knife, if you follow those steps it really is quite plausible to cut those rabbets well with no power tools.

More tools - Luthier, jeweler, fly-tying
vossiewulf replied to vossiewulf's topic in Modeling tools and Workshop Equipment
Looping back to this subject - some time ago I received coarse grit full-diamond strips, and I put them together with the earlier Horico medium-grit strips (I hate it when companies use meaningless generic terms like that; I'm guessing the coarse is ~100 grit and the medium 320-400 grit). I've glued them to a piece of .018" spring-temper steel. I've been using an identical tool for my planking covered in various grits of PSA, I'm going to try this version as soon as I finish the knives I'm working on. I used this glue - anyone know about it? Besides scoring the "typo our own slogan on the bottle" achievement, as you see they claim to do better on unfriendly materials and combinations. However it seems to me to be just low-odor CA, although nowhere on the bottle or anything else I've seen have they said this is CA glue. -
Thanks Don If you can get to a point where you have a blade that just needs a handle, let me know ;-) It's the couple hours of icewater grinding that I'd be perfectly happy to not do again for a couple weeks. I never mind making the handles, it's a bit of precision joinery that I like. And also as you start sanding them out to final appearance you get the reward of seeing wood like this all nice and shiny for the first time, that's always fun. I've used them before, I agree it works but this is where form goes up against function for me and form wins And if you hold these the way I do, it really can't get much more stable. BTW these knives are ambidextrous, I find myself using my left hand to do things often enough these days that I decided to make them left-friendly too.

First, india ink vs. Faber-Castell Pitt pens. One of these is india ink and the other is the Pitt pen. Looks identical right? Now let's change the orientation a bit so we're not getting direct specular reflections and we just see what their ambient color is. Not quite so identical. The one on the left is india ink, and has as close as we get to a pure black ambient color, while the Pitt pen is dark grey. And this is not surprising when you think about it, I'm sure the ink in the Pitt pens started with a foundation of india ink, but pen inks are highly engineered substances at this point- they probably added flow enhancers and drying retarders and who knows what else to give the pens a long life and proper function. And if you have something that's pure black and you do anything to it other than add more pure black, it's going to change it to a grey color. So I'm going to hang onto these pens, but probably use them the same way Popeye does - for small areas and deck plank caulking. I experimented with using makeup application sponge brushes applying india ink last night, and it worked extremely well. In fact I'm wondering why I don't use these for any non-laquer finish, there are no brush marks and it can carry more paint without dumping it all in one spot, only smoother way to apply something is by airbrush. This "brush" is what I was experimenting with. However I also bought these, much cheaper and a long term supply, haven't tried them yet but see no reason why they won't work fine. I'll just cut them in half and stick them on a dowel to use. While I was at it I also bought this, not for brushes, but as liquid application/cleanup swabs, was a shot in the dark but turned out to be a good choice - these are a good size and the swab material stood up to some pretty heavy scrubbing (I used one with some acetone to clean out tape gunk from one of my new knives). As in it wasn't damaged at all and was ready for scrubbing round 2. They also have a strong plastic piece inside the swab as reinforcement, which really helps if you're using swabs for cleanup. And best of all, ZERO lint. Anyway, for 6 cents a piece this seems a good purchase. Now back to the knives - don't worry Rick, we're almost done First, another tip - this applies to cleaning up any surface actually, but is REALLY important shaping something roundish like these handles: you want to be positioned under good light, but at a very oblique angle. This enhances the surface detail and makes it much easier to see the bumps and recesses that you need to see to produce a smooth final result. In fact if you don't get yourself under light like this, you might as well close your eyes and go with touch as your main sensor to tell you where you need to sand and where to stop, because direct light hides all this information from you. Along in here I also crosscut them to their final length. This pic should explain why And here is my new grip type, I'm going to call it a dromedary handle. Test-driving strongly suggests it has some advantages control-wise over the pregnant snake design. That works very well also, but I think the dromedary might be the superior of the two, will see if that holds true once we get some real cutting miles under the dromedary knife tread, to horribly mix several metaphors. Also, it should be obvious that an important part of the reason to make non-round handles like this is so they stay where I put them on my bench. No rolling for you, Tom and Jerry planking knives. This is also the point at which we stop with the power tools and from here it's all hand-sanding. As Popeye would say, there are a couple of knives in there and we're getting pretty close to finding them We want to go slow here and be quite careful about what we are doing, it would be painful to screw them up at this point. So we work our way through the grits, regularly comparing the two and using our oblique light to help us get nice smooth continuous curves with a round (from end-on) tail. And we look very carefully for those little scratches that like to hide until we have our CA finish on when it's a major pain to fix, see the spot I'm pointing to. The transverse scratch near the end won't come out, that is where the burl snapped in handling early on. I'm hoping that the CA finish hides it to some degree. I won't mention how high we go in grit, because Popeye, who is guest-starring in tonight's episode, would have his eyeballs emulate his handle and pop out and do a full 360 before popping back in. All I can say is those who say there's no advantage to sanding to a high grit are somewhat less than 100% correct IMO it makes a very significant and positive difference in the appearance of wood to have the fibers be cut as cleanly as possible. On holly, with nearly invisible grain, it is in fact probably not worth it - there's no grain to show to advantage. But if the wood has a dramatic coloring or grain pattern, it will be considerably enhanced by sanding out to Popeye eye-popping numbers. Just need to drill out the tails for their brass balance pieces and they can go in their thin CA bath to start the finishing process. Here is where I do wish they were round - round handles can be chucked in the lathe and then the CA coats can be applied with a pad while moving down the spinning piece, leaving a nice smooth base for final sanding. Without that, getting a level CA finish on the whole handle takes a while and a goodly pile of sandpaper.

Fokker Dr.I by Torbogdan - FINISHED - Model Airways
vossiewulf replied to Torbogdan's topic in Non-ship/categorised builds
That's all standard 3d printing stuff, there are multiple packages designed specifically to set up a model for 3d printing with the appropriate supports and orientation and they check minimum feature size. The latter you have to check and know before you begin modeling, you can't just model whatever and expect it to 3d print at any scale. You have to plan for and create different versions of your models at various scales as the minimum feature size shrinks relative to the size of the model as you go up in scale. None of them are insurmountable, but it's also something unlikely to be navigated by someone who is not a very experienced modeler. Once I get my desktop up and running again I plan to work on printing some of my work through Shapeways and maybe offering some models useful to people here and in other (physical) modeling areas, I'll let folks know what I learn. -
