Gates are closed and the bridges are up sir!!, but i do think we have a bit of a problem, poking with a stick at David is the same as pulling a grizzly at his tail, be aware!!!<br />
Anyway, he allready has me addicted to his SD's , we're screwed!!!!<br />

Manfred's right. Back to you, Bart. I'm very much enjoying watching you work.

And so sorry to hear that the Flu has hit your house ... Ellie and I just got over ours, took over a month to shake it off. Wish you and your bride a much, much quicker recovery, Bart.

Ok guy’s I’ have done some more work on my tooling.

As previous stated I have three tools for the sub, all three are finished now, the finish is not what I wanted to be but I’m forced to be left handed for the moment.

N°1: The towed array pod tool is a straight forward the wax is in place

N°2: The small parts tools for vacuum casting, this tool is a little special as it’s is a pocked tool what I mean with that is that three of outer edges of one of the tool halves was not sprayed with release agent and consequently both halves are permanent fixed together at those places. The tool only can open were the castings are positioned in order to get them out.

N°3: The third one is the largest tool I made so far. I have dimensioned it so it will just fit my pressure pot. I had some trouble to get both halves of the tool leak free when I squeezed them together. (YES I ALWAYS TEST MY TOOLING USING WATER AND YES I’M CRAZY BUT SPILS ARE EXPENSIVE). I normally used David’s way by applying rubber bands bud it failed I could not reach enough pressure to prevent water pouring out in some areas.

As space is very limited in the pressure pot I fabricated some clamps that, when in place, just fitted in the pressure pot. The clamps made out of some wood leftovers and 4mm threaded studs. The test was OK now no more leaks.

Thks....probably because my daughter assisted me.

I did the touchup of the scribing lines (thks to Andy I found the right putty that does not affect the paint) ......time consuming but afterwards I was amazed with the amount of damage that became visible when it was filled with red putty (most of the damage were broken off paint chips around the edges).It’s was worth the effort.
I hope I can finish the scribing when I’m up and running again.

Had to split the WIP to make it work.......I will NEVER understand IT.

Today I have done the casting….....no leakages........……the vacuum casting worked well David, MANY thks for your explanation on that. After degassing the tool I placed it in the pressure pot together with the rest of the tools.
I have to wait some days to see the result (it takes 7 days to fully harden). Hope the prep work pays off.
The picture is showing the cores in place together with the bushings witch will be embedded in the parts.
