HMS Pegasus 1776 by Trussben - 1:48 - Swan-class sloop based on TFFM

Let us know how much you need to do to square up those corners.

Hey Greg,

 

Using a 1/16" router bit just leaves a slight round that just needs a quick swipe with a square file to remove.

I would of used a 1/32" bit, but its cutting depth capabilities were not long enough to cut deep enough into 16" stock ( 15" + 1" for onion-skinning ).

Hi All,

 

I was having a lot of issues revolving around the QD Transom piece that I have now figured out and thought I would share with other SWAN-TFFM builders, not knowing if this has been recognized before.

 

On page 11 of TFFM-Vol #2, there is a pattern supplied in 1:48 scale for you to use to cut out your blank with, however it appears it is not the correct size!!

 

Let me explain that I tried using this pattern and kept finding it far to wide compared to my own Pegasus aft framing and I was starting to worry until I decided to check the pattern's width as compared to other drawings in TFFM.

If you compare it VS the "elevation of counter timbers" drawing on Page #9 TFFM-Vol #2 you will find the pattern is approx 3 11/32" at its widest point but the drawing is just about 3 3/32"

I decided to test it against another drawing on page #182 of TFFM-Vol #2, this shows the Quarter deck beam layouts but it also shows the QD transom on it, and this as well makes the Transom 3 3/32" wide.

 

SO - I copied and made a template using the page #182 transom and this fit almost perfectly to my model.

 

See some pictures below showing the difference in size and what my new one using page #182 looks like.

I find the patterns excellent GUIDES, but unlike the plans, the book (or my building) needs some adjustment. 

[Trussben]

Here is the QD transom and aft framing completed for the moment.

 

[giampieroricci]

excellent work!!!

[albert]

Very very nice. 

[Trussben]

Waterways installed.

 

[Trussben]

Started design work on the Taffrail, playing around with the CNC to see what details I can easily incorporate, here you can see two prototypes using the TFFM dimensions for thickness”s and the shape from my Pegasus draft.

 

 

[druxey]

More CNC.... Soon you can just sit back and let automation take over!

[Trussben]

It’s just another Tool David! 
 

Here is the very difficult to make by hand Taffrail capping piece, 1.5” thick by 8” deep, very very delicate pieces!

 

[dvm27]

After the previous post I was wondering of you could make that incredibly complex taffrail rail to match. I have my answer. Brilliant work Ben!

[druxey]

Nice wiggly tafferel rail, but the number of cross-grain sections will be difficult to work with....

A noob question here, but what would the option be? Several shorter pieces steam bent to fit or how would one do it?

My other thought would be to laminate two or three thinner pieces and make a form to bend them around, at least that's what I will try if using these proves too fragile.

[Wintergreen]

Yes, that was another thought I had. However, that engages some difficulties about very thin pieces to laminate. 😮 

Can't really tell from the pictures, but I guess the thickness is somewhere around a mm or 1-2/32"?

[druxey]

In the past, at 1:48, I've put together several pieces to form those compound curves. The rail also curves in plan view AND is sloped as seen from the side!)

[Trussben]

Framing around the rudderhead underway, you can see the 3 pieces roughly shaped and trial fitted here, the hole for the rudders shape will be finished after they are installed.

 

Druxey - no CNC parts to be found here! All hand made.

 

[dvm27]

You should try a mock up rudder in the space. For some reason none of the rudders on my models will go through the full range of movement because my openings are too small.

[druxey]

Nicely done, Ben. And Greg has a good point - it has happened to me as well!

[Trussben]

I finished blending in the Rudderhead framing to the stern and then started mocking up the upper counter and stern light layout - still needs tweaking.

 

[Rustyj]

Very nice work Ben!

[druxey]

Mockup looks great, Ben. Just be sure to slope the 'verticals' of the lettering to match the angles of the counter timbers as well. A subtle but nice refinement!

[Trussben]

Thanks Everybody for the comments and likes.

I will give that a go and see what it lt looks like David.

This is an interesting nuance to the rigamarole of stern construction.

[Trussben]

Bit more tweaking done to stern layout.

 

[Trussben]

Lower counter has been planked and the rudder hole filed to final shape using the actual rudder to make sure it has the correct clearances.

I added the carving from the Pegasus draft into the middle coving of the Taffrail but the ones in the outer coves will just be textured as they are too small for me to make very easily.

[Trussben]

After a few experiments and four different versions, here is my final Tafrail that I managed to get the garland carvings into the outer coves just like the Pegasus draft, I also “textured” the coves like the draft.

 

[Trussben]

Thanks for all the likes everybody!

 

Here is the stern mock-up including my stern light design and the lower counter, really starting to come together now!

 

[Seventynet]

This is beautiful! I assume you used your mill for the lights? I’m interested in your next steps to finalize them (my own attempts frustrated me!).

thanks,

Ian
