Bomb Vessel Granado 1742 by mobbsie - FINISHED - 1/48 - cross-section

[mobbsie]

Hi Denis,

 

The jig is in the plans mate, the materials are very much down to the individual builder. Fortunately for me it wasn't that difficult to make.

 

With regard to the power tools, I'm finding out their limitations, tends to make life a little interesting.

 

Be good

Mobbsie,

 

the curve of your keel rabbet confuses me. I thought that it is nearly a straight line midships.

Your frame is looking nice.

[mobbsie]

Hi Christian,

 

Thanks for looking in mate,

 

To answer your question regarding the keel rabbet,  The rabbet starts to turn upwards from frame No 8, this follows the line of the frame No's  9, 10, 11 & 12. The Keel actually rises 1mm along it's length from 17mm to 18mm, the rabbet reflects this rise.

 

Hope that answers your question without confusing you.

 

Be Good

Just found your new log. Looking forward to your updates! If it is anything like your Agamemnon then it will be beautiful! 

[mobbsie]

Thank you Sherry, that's really kind of you.

 

I will try to make a decent job of it but fear my carpentry skills may not be upto the mark, I will however try my best, as we all do.

Mobbsie,

 

thanks for your explanation. But I can't follow you.

If I have a look at the original drawing at the NMM (see here) the rabbet doesn't have a curved line.

You're sure that you do not misinterpret a line on your drawing?

[mobbsie]

Hi Christian,

 

I have looked again at the drawings and have come to the same conclusion as before, there is a definite rise in the keel rabbet.

 

I have taken a few pictures which hopefully will show you this rise.

 

This is the whole Page                                                     

 

 

The section with the rise is shown in the black box

 

No1 is the keel and shows the end profile of the rabbet

 

I hope Christian that you can now see that I have followed the drawings correctly. I can see where your coming from and it does look as though there is a difference, but as I'm building from the drawings I have to go with that.

 

Hope that helps mate.

 

I forgot to mention earlier that with Grants help and generosity I will be posting an update of my first complete double frame.

I smelled popcorn.

(btw how many of those machines is Sjors operating?)

Hi Jan

 

Welcome aboard mate, glad you dropped in.

 

Sjors has the complete franchise on Popcorn machines in MSW, look out anybody who tries to muscle in, his empire is growing so it's impossible to know for sure just how many he has, I'm scared to ask.

Mobbsie,

 

now it's clear, but I don't have any idea why the author of the drawings choose this solution. It is in my knowledge not common.

I've had a short look at the prototype build of Mike at MSB, but could not find a picture of this area.

I would suggest to build frame 12 and check if it is on top of the rabbet ot your model.

[mobbsie]

Hi Christian

 

Thanks for the suggestion mate, I have placed the 2 double frames I have onto position 12 and 8 on the keel and if anything the rabbets not high enough. I know their not frame 12 but their almost identical, I don't plan on making that frame just yet. The way I'm going is to make frames 0, A, B, C and D, I will then make up the rest of the doubles that's No's 12, 8 and 4, then fill in with the remaining singles, so it's going to be a while.

Hi Guys,

 

Time really flies and boy am I due an update.

 

Thanks for all the comments guys and for those that hit the like button.

 

I've experienced a bit of aggro fitting the frames into my jig, the jig seemed to be too big and the frames flopped around inside when fitted.

 

It turned out to be two things, firstly the top cut outs on the jig were deep and so did not hold the frames as it should, secondly my centre line on the jig was out of alignment, bearing in mind this was my first practice piece it's hardly surprising.

 

I was also having a bit of trouble with my glue, it just wasn't holding the 9 parts of each frame together. Following advice from my build partners I changed the glue and although it's early days this new glue seems to be doing the job.

 

The glue I was using was Ever Build 502 which stood me in good stead for the time I was building the Agamemnon, this glue only has a life of 12 months after the date of manufacture and unfortunately there is no date on it, anyway I got some Evo-Stik weatherproof wood adhesive, seems to be good stuff. 

 

The long and short of it is that a new Frame Jig was made, this time properly and it's now doing the business.

 

Both Grant and I differ on this next area, it's only athetics, I wont go into what Grants doing but I am not putting treenails in the frames. Looking at AOT's there are bolts around the bottom section of each frame, I decided to use 0.7mm oval head brass pins for these bolts with 0.7mm flat head brass pins on the revers side. I decided to leave these brass colour, you know me, that's the look I like.

 

Enough chat, I have a few pics showing you where I'm at, please, if you have any comments / remarks don't be afraid to ask or make suggestions. I'm here to learn.

 

The first two pics are of the new jig

 

 

These are the first 5 frames 0, A,  B, C and D, 0 and D frames are doubles

 

This is the 0 frame showing the bolts.

 

This is the jig with the 5 completed frame in position

 

So your right up to date now guys, destructive then constructive comments are always welcome.

Great to see an update Tony! The new jig certainly looks the business, and your frames are looking great too. I'll be doing some tests with copper bolts this weekend, so we'll compare notes after that.

[Beef Wellington]

Those frames look fantastic, no gaps at all and beautifully shaped, can't imagine them coming out any better!  Looks like you've been doing this for years.

[Sjors]

I think Jason is right !!!!

You did this before......  

Very nice Mobbsie !

And I like the bolts/nails.

A few frames left.......

[trippwj]

Those frames look wonderful!  Now, did you go all out and add stopwaters etc? :rolleyes:

 

I can understand fully the challenge on the framing jig - from what I understand, if that is out of alignment it will come back to bite you down the road - often painfully!

 

Enjoy the build, Tony -

[popeye the sailor]

very nice work in filling the jig........looking very good 

[ASAT]

I thought you said you needed to up your game?? Those frames look great to me!! So are you bolting all the double frames? i looked at the aots and I am even more confused, the chocks are not in the same locations and the chocks themselves are treenailed / bolted? It looks like the bolt heads inmy scale would be 1.2 mm or so.... Wher did you source your pins? I do love the effect of them though....

[mtaylor]

So first scratch build... you claim.   Looks like you've doing this all your life.  The frames and jig look great.

[mobbsie]

Hi Guys,

 

I would like to wish all my friends and members of NGR'sMSW a Very Merry Christmas and a Happy, Healthy and Prosperous New Year.

 

Thanks guys for all your help and support during the past year.

Hi Mobbsie,

 

Just catching up, I see that you're enjoying your conversion to the darkside my friend, beautiful work Sir, that is a wonderful looking set of frames!

[mobbsie]

Hi Guys,

 

About time for an update, it's been a while.

 

Now what was I doing ? Ahh yes that's it, FRAMES,  well frame production is still going on all be it slowly what with the holidays and all but I'm pleased to say I only have 1 single ( 11 ) and 1 double ( 12 ) to do, they are all cut out and ready for final adjustments and making up.

 

Talking with Grant there has been a change in the method of holding these frames while being constructed, where I used pins to hold the pieces in place I am using Grants method using double sided tape.

 

This method allows for more frames to be made at once because no pin board is required, I only have a single pin board. I don't have a picture of the new method but should anybody want to see it Grant has posted some in his log. 

 

I also had a problem when the frames were placed direct onto the template in as much as I was getting ink in the joints when gluing the frames together, I got around this by using a piece of celotape over the template joint. This has cured that problem so all I need to concentrate on is getting a good fit with the wedges, (still trying to get them right ).

 

Grant and I were also discussing which finish to use because each stage will need to be finished before moving on. Minwax Satin seems to the favoured choice but unfortunately it's not sold in the UK, at least to my knowledge, so I thought I would use Tung oil, I applied some to a practice frame made from Swiss Pear and although it looked OK it is quite dark, I looked to see what is the UK equivalent to Minwax and it turned out to be Clear Polyurethane, I already had some of this and tried it out although it was gloss and I wanted satin, it's a lot lighter and does look better so another trip to the hardware store and that's now sitting waiting to be used.

 

I only have a few pics mainly because frames are frames and have been shown before.

 

My old system of frame holding

 

The next 3 pics are where I am at the moment

 

 

 

On the right is the Tung oil, left is Polyurethane

 

 

So that's it guys, a bit disappointing really, I will post again when all the frames are complete although there will still be a fair bit of work to do on them before moving onto the next stage.

 

Be Good

Great progress Mobbsie. I'm glad the double sided tape worked out for you, and also that you found a finish that you like. I need to extract the digit and get a move on now to catch up!

[Canute]

Poly looks good, Mobbsie.

[DocBlake]

Very nice work.  I'm itching to start, but I think I'm going to do a kit-bashed "Rattlesnake" before going over to the dark side.

 

Dave

[jeff1395]

Great progress!

 

Jeff

[jwvolz]

Good progress Mobbsie. Frames look great. I'm sure you'll come up with a good solution to the finish. 

[Trussben]

Looks like the Dark side is strong with you!

 

Ben

[Jack Panzeca]

Hey mobbsie,

 

Terrific progress.  You are flying.  My plan is to use poly as well.

 

Great work my friend.
