Piston question
My old homemade ring filing fixture. I made this several years ago from a couple of extra parallels from my seat and guide machine.
You measure your gap and figure how much you need to file and use 2 feeler gauges to set the small plate that you butt your ring against. Make sure the ring is square against the plate, and tighten the parallels to hold the ring.
then remove the small plate and file the ring until it is flush. This saves me a lot of time since you don't have to file and check over and over to get the right gap. File once check and done.
The parallels are doweled together. I have to true the filing surface on the belt sander after about 4 or 5 sets of rings.
