[PSUBS-MAILIST] Pod Seals

["James Frankland" <james@guernseysubmarine.com>]

Hi Everyone.

Quick question.

Ive been machining the alternative sealing arrangement for my battery pods.  I had problems with the cladding system shown on the K350 plans so after messing about for ages trying to get that right, i gave up and have opted for a straight forward flat rings and O ring seal.  I know its not as streamlined, but it will be easier to get the pods open.  (thats my excuse, the real reason is that they are easier to make!)

I have nearly completed the machining work on the endcaps as well now (not shown).  BUT, there is another problem.

Due to distortion from welding, the nice straight holes i drilled that all line up, are no longer straight.  I drilled them all 9mm.

The question is,

1, Leave them and just use a smaller bolt?  Does this tollerance matter?  As long as the bolts pull the 2 faces shut.

2, Do i drill them straight again?  Maybe 10mm.  I dont like this idea as i dont want to damage the machined surface and it will be awkward to hold the caps vertical somehow.

Option 1 surely?

Any ideas?

Thanks as always.
