My Comet primary cases leaks! I have resealed a couple of Comet primary cases over the past year and not had a problem. Clean, remove any dings, make sure no high/low spots, no flycut grooves , or screwdriver marks, no cracks at drain plug, ...etc. Using some Hylomar sealer, assemble...no problem, no leaks. This Comet case appears different or i am getting (or remaining) as stupid as ever. Maybe one drop per hour with case at fill level.
I have cleaned, inspected, used Hylomar, trimmed threads from new SS case screws to assure full pull, cleaned all case tapped holes for swarf, chased threads......the only suspicious item is flycut grooving remaining in the outer case T5/4.
So the advice i get is the time old standard "get glass sheet, smear with grinding compound, figure 8 the case till smooth" and this seems reasonable, but for some reason i dont like it. If you like it , i dont need a retort on the technique, i might use it, i understand it.
I want an alternate method, i do not want to drag a file across the case cover, or an autobody sander.
I am thinking of a large sheet of 400 grit glued to a surface block, but i cant find a large sheet of 400.
any help ?
Cheers
