... you're not helping.

Thanks for that mental imagery -- I'll have to scrub my brain with Drano to get that out of there.

That box will fit the Gato!

Yep, boxes and cats, they simply can't resist them, i know the problem myself.

Perfect fit. And with the teeth end stuck at the other end of the box, you can fit the control rods and drive shaft without getting bitten!

Mr Merriman the box you sent over is a very tight fit......but it’s still OK.

The tube inside I can use in the Akula and I have plenty space left.
That SD is one incredible peace of engineering sir!

Grtz,
Bart

Test fitting the box








The SD fits perfectly inside

LOL
I'm a social disabled, dyslectic, SOB trying to copy what others have done before me......lucky for me I’m good at it.
Welcome into my PERFECT world Scott.
Halleluja! indeed.

Hummmm... speed versus quality. What a conundrum - fortunately I have no choice. I don't have enough talent to take the slow and perfect route like you. For me, its always quick and dirty. Halleluja!

You better be careful - there may be a conspiracy afoot to never deliver your SD

I was......I received the shipping confirmation before I posted the WIP, Now I'm concerned about the water soluble glue he might have used to assemble the SD.

How long did it take to make those brass stencils?

It took between two and tree months....compared to your speed Scott....I'm captain slow.

Man alive. How long did it take to make those brass stensils? You better be careful - there may be a conspiracy afoot to never deliver your SD so that we can all sit back and watch the wonderful things that you create whilst you are waiting for it to arrive!

This is fantastic Bart. I can't see the photographs of the brass and GRP stensils for some reason.

Thks Scott...Repost below

Someone on this forum suggested that I spend the last few months looking at the letterbox waiting for the SD to arrive, leaving a trail of drool throughout the house.
So it’s time for a WIP to prove the contrary ( he was right about the drooling though).

Marking out the hull for scribing
I tried several ways to see what was suiting me the most (yes I’m crazy).

Lofted the info from the drawing and foto’s and

• directly transferred them onto the hull
• transferred them to GRP made laid-up stencils from the hull
• Transferred them to brass sheet 0.010 x 4 x 10”

The last option I liked a lot so I cut out the transferred shapes. The disadvantage is that it takes ages to do it right and You have to bent them into shape after you are done.

The GRP made stencils...will not be used






The brass sheet stencils, one is shaped to the hull, trimming still to be carried out.








I now have all the parts that need casting, so I’m in the process to create the tools for them.
I will have tree tools
one for the tow array pod (the pod has to be hollow) so I will try a sort of lost wax method with the use of a core. Did some test concerning the melting point of the wax and the behavior of casted resin when heated up. Should work, will keep you informed.
One for the little parts on witch I will use David’s vacuum casting technique
And then the last one, the “normal tool for all the other parts (still have to complete)

Tool for vacuum casting technique








Tool for lost wax method, wax caliber just below the master of the pod
