Here's the cylinder in question:
Finger Clock Measuring instrument Household hardware Circle
Household hardware Material property Auto part Circle Rim


I already contacted Accucraft about the defective cylinder block, but I'm curious if I can get it working in the meantime.

This cylinder was from a Ruby kit I recently purchased and started assembling.

The cylinder was cast improperly and probably had a bubble, or not enough brass was poured. Either way, there wasn't enough material and there is a small recess in the cylinder wall which causes the o-ring to bind.

My idea to fix it would be to strip the paint off the cylinder, heat it up with a torch, and apply some solder to the gouge.

I would then polish the solder flush, to act like a filler material.

Is this feasible? (Or even worth doing?) Or should I just wait on Accucraft's response?

Thanks.

I would wait for accucrafts response first, but a 'repair' I would consider is machining out to a bigger size and putting a sleeve back in to the original size.

I would really prefer to do it this way, but at the moment, I don't have a drill press/ milling machine so drilling out the cylinder at dead center would be difficult.

Thanks for the advice though!

As Russell mentioned in post #4, Tripe R Services are agents and Ryan is very knowledgeable. He may even have spare cylinders in stock that he can charge to Accucraft!
If there is a possibility they might have cylinders in stock, I might have to contact them.

It would be great if they would charge it to Accucraft, because after all, it’s a factory defect.

Thanks for the comment!

I think it would be cool to have Bill Allen bore it out, make the other one match. And make new pistons for the larger bore. More power potential.

Could you fill the house with jb weld, push out the excess with the piston and clean it up?
