ok I have come to a definite decision...maybe...kind of...
I had a look through several websites last night with details of hydraulic seals and recommended land geometry, clearances etc. Seems that .019 clearance is the largest I could find as allowable on a particular style of seal, that is total clearance on the diameter so the .040 that I will have with the old piston in the new bore is not an option.
I contemplated plating the old piston but I decided it would complicate the geometry of the seal grooves, perhaps too much for my limited abilities to deal with.
So I will go with Tom and Greg's recommendation and make a new piston that will take a standard, off-the-shelf hydraulic seal and wear rings.
My next question is, what material would you guys recommend? I'll have to make a special trip to a steel supplier for a chunk of stock of sufficient diameter, so the slate is blank.
