[SEL] Maching blank pistons

[Ed Stoller]

Peter.I have more pictures if you can use them.


PistonRings..

I have made quite a few rings for my engines as well as for friends using

the heat treat method and so far have not had a failure. If you have access

to a lathe its one of the easiest parts of a restoration.

Heres how I do it. Chuck up a bit of good cast in your 3 jaw. Bore it to the

fitted ring I.D. Machine the O.D to your bore diameter. Part them off. Split

the rings. ( I use a bit of pressure with some bolt cutters and they

fracture cleanly) Make up a wedge out of a bit of keysteel or whatever is

laying around and stack the rings together with the wedge in the gap holding

them open. Wrap some fireproof cloth to keep the direct flame off them. Put

the stack of rings between two plates with a 3/8 bolt holding them together.

I make up a little firebrick furnace on the shed floor and stick in a LP

torch and keep them to a dull red for a couple of hours. Pull them out when

cool and gap them.So far the rings I have made have gone into new bores and

there is no leakage past the rings and seem to work perfectly.
