Hi FrankD
I have booked a large lathe for tomorrow to cut the groove the way you said
with a dovetail makes sense ,I faced my C.T ring today the stainless looks good
maybe my next build will be completely 316 .I ordered that book looking
forward to reading it.As for my hatch I was hoping to slot the hinge pivot to
allow the 2rings to mate evenly with each other Brents suggestion of the gas
filled cylinders for assisting with opening and closing could possibly made out
of 316SS and fixed on the outside instead of springs, I wonder what gas they use
possibly nitrogen.
have you already made holes in the bottom of your MBT's and if you have did
you test them for leaks with compressed air before you did when I built my VBT I
done this and was astonished to find a pinhole it really burst my bubble I
thought my welds were perfect I am planning on doing this with my battery pods
as well as connect a extra ball valve and gauge to the outer thread of the flood
valve barrel nipple and connect my trucks carburetors air intake which should
give me some serious vacuum until the trucks engine dies at which time I plan to
close the ball valve and check for leaks if the gauge drops over a period then I
know I have a leak obviously the real test will be in the water
.
Any thoughts will be appreatiated.
All the best
Glen SA
