Hi Bob and Mark, Yes a bit outside the box so to speak. Mark you are correct the whole U shaped piece moves up and down vertically the trick is to make sure that the blade is set vertical as well I am still working on that The use of the saw feels a lot different than a regular jewelers saw so I am unfamiliar with the fell of it , I will probably stick to the hand one for metal but I think that for some of the woodwork there is definite potential. Still a few kinks to work out but it feels quite promising. Tomorrow is another day. Oh yes and thank you all for looking in and the likes Michael

Bob the only part that I have now decided to keep is the base casting and the tilt table. I machined up a piece of 3/4 inch thick aluminum scrap I had in the scrap box to fit to the cast iron base this entailed drilling a few holes so that I could bolt it up. It took a while figuring out how to hold the odd shaped casting but it all worked well in the end. This next picture shows the new slide block attached to the casting. the rod that slide up and down is a polished 3/8 roller from and old scanner. at the top end I silver soldered a U shaped frame bent up from some 1/4 x 5/16 bar steel I heated it to cherry red with the propane torch in order to accomplish this. a side view, just to the left you can also see that the 5/16 x 1/4 bar has a 90 degree twist so that the wide dimension become vertical for the U portion of the frame. A spring from the spring scrap box was shortened to act as the return up. The grey steel frame has been set aside to be used for another purpose and the base of an old treadle sewing machine has been dragged back into service as the power source for the new powered jewelers saw. presently as a test to check out the principle the bottom hook of the slide is connected to the front of the treadle with a bit of 1/4 inch line. This arrangement seems to work quite well and there4 is a great deal of control on the speed which is much slower anyway., the flywheel effect of the sewing machine large belt drive is a bonus. From the end the overall profile, all that is left to do is add the blade holders for the top and bottom the bottom one will be threaded into the steel bar just in front of the slide, the top one will function the same way as the small jeweler saw that I made some time ago. I will place a new full top over the sewing machine one I might move the saw to the left so that I can take advantage of the treadle drive for a belt driven tool in the future. All a bit Heath Robinson but I had not used the sewing machine in twenty years, and I have others anyway. I use the jeweler's saw a lot and this will be just another version of a great saw. Michael

Great to see an update Russ. Michael

I have an old (brand new ) 2 speed 16" Delta Scroll saw model 40-560 That i purchased 20 years ago. I have used the saw as manufactured perhaps 3 times and even on the low speed thought it was rather challenging to get a smooth cutting action. so I mostly used the jewelers saw because of the much smoother control. What I am looking to accomplish is to use jewelers blades in a scroll saw in order to be able to cut both wood and metal with a little more precision than I can presently achieve by hand. My question relates to the action of the blade which seems to not move up and down in a vertical mode is this a common condition of scroll saws? I only discovered how much this moves off vertical when deciding to make this tool work without power so that I could slow it down more, and work with both hands on the work. I took off the motor and all the electrical parts and jury rigged it up on a metal frame I had kicking around, I used a rope to a foot lever to pull the saw blade down and a tension spring to pull it back up, the geometry of the arms is the issue. even with the rather disconcerting motion of the blade essentially in a back and forward motion as the blade goes up and down the ultra control with my foot pedal made cutting some very small parts manageable and far easier to control than when under power.

Hi Denis there is a great material for open metal treads it is an aluminum sheet for sculpting I used some for these steps Michael

Oh OK now I understand, it is interesting that on some of( Gil Smiths PDF) Catboats he used as few as 11 planks I think it was. Here is a great set of photos of a catboat being planked. Michael

I think it look like you have done a great job so far Ian, I wonder if you laid it out for 7 planks on the opposite side and looked at the difference regarding the sharpish turn at the bilge on the transom landing in the middle of the plank on the side that you have marked with 6 planks. I personally would go with 9 planks because I think it would feel better to me. Not having the model in front of me I could be just completely out of it, it is just an opinion. Regards Michael

I hope the show goes well in Rockland. Michael

Albert Adding to all the positive comments seems so inadequate, it is so inspiring to watch an artist making magic. Michael

Hi Johann, thank you for posting the pictures with the work in progress. When looking at the macro photographs it becomes easy to forget just how small these superb model are in their own right. When the tiny parts are part of the overall picture with your hand holding the very small drill while working on the "nails" It suddenly puts the whole thing into perspective. Your photographs are both very inspiring and humbling, and also educational at the same time. Michael

Hi Druxey, beautiful work, your fluting inspired me to jury rig up a fluting tool based on one I used in an architectural model in 1977 I have linked to it in jigs and tips Michael

Oh Glenn.... I'm mortified.... simply mortified Actually I had not realized the rods were that small a diameter, and if you mentioned the diameter in the text I missed it because of the impact of the pictures. And who need to struggle with 000 x 120 anyway. Michael

Beautiful work Mike Michael

96 U bolts, that's 192 threaded ends, a lot of threading and tapping on top of the woodwork, you were a busy man this week. Michael

And Paul's mother said... "fear is the mind destroyer" I heard Ray Bradbury speak during a dinner under the wing of the spruce goose in 1986 at the ASTC conference. Michael

Quick update I roughed out a boom today it is clear fir I will sit on this for a day or so and see how it feels then/ Michael

My goodness I can't even keep my computer desk that clean and tidy. The hull framing is looking very nice. Michael

I'm just lost for words.......Where are those knitting needles..... I must find them. Lovely Druxey. Michael

Hi Steve, Thanks for the tip regarding the soldering, I know that one need a little more heat to un-solder Initially I had thought that my large iron would be good, but I thought that the propane torch would be quicker, it was definitely a surprise that it did not just fall off. Isn't that the great thing about this hobby, we just keep learning new things all along. At least I know how to get that aged bronze look on a small piece of bronze now. On a side note I just finished reading the silver soldering article in the spring edition of the Model Ship Builder Journal it is very good. I might just invest in a smaller jeweler's torch and some of the paste type silver solder as well, I need to get some more liquid silver solder flux. because soldering the two small pieces of brass rod was a bit of a pain with the paste flux which kept falling off the small parts. and thanks to all who added likes and comments Michael

Thanks for all the positive comments and likes. Continuing on with the goose-neck the filing of the opposite side.and the ends I also needed to thin down the tongues a bit. Next the holes for mounting to the mast were drilled and countersunk. Then some final polishing, this was done with some wet and dry narrow strips and a brass wire hand brush. the piece was now ready to be unsoldered. The releasing from the bar did not work in the way I had imagined, I had expected the short piece of bar to drop off because of its weight, but this did not happen, the capillary action of the soft solder was greater that I had anticipated, and by the time the assembly had gotten quite hot I realized that I would need to assist the parting. this I did with a steel scriber. I had to work at removing the scale next, more work with the wet and dry and wire brush, the resulting look was now more like aged bronze with actually works for me. the swiveling part of the boom end was made from a couple of pieces of brass rod drilled out to be a loose fit on the pin. The goose-neck is now temporarily attached to the mast with some dressmaker's pins. Michael

Very clean work Paul. Michael

Nice looking Dog Nenad..... but how does it see where its going with all that hair over its eyes? Michael

Wow, Iain those decks look superb, are the decks more accurate than the foam? if that is the case could you not set the hull up in the cutter and remove the area and make a new part out of foam to drop in? The other thing that this brings to mind is of course the order of cutting, which I am sure has already occurred to you. I am really enjoying seeing this application of the present state of this technology, and just think about what is next. Michael

Thanks for the compliment Druxey, and thanks for all the likes. Just a small update after filing the first side to a closer shape I needed to clamp the opposite side but the conditions were now different and it did not want to clamp the same as the first. Here you can see that the base has been thinned down a lot. The solution was to soft solder the base to the 9/16 rod this will be helpful also when it comes to drilling the mounting holes for attaching to the mast. Michael

Druxey it just gets better and better, The presentation on the base looks perfect.The burl worktop is pretty top drawer too. Michael
