38 Flattie Valve Seat Problems

[Frank L.]

As some of you know I am part of a team that is currently restoring a Universal Carrier and we are running into a few problems with the engine....

After removing a few valves that were sticking (thanks for the tips BTW) and cleaning them up we noticed a problem with one of the exhaust valves....

Because it was stuck open for so long the valve seat has scaled and rusted nicely

My question is: How can a shadetree mechanic resurface the seat without messing up the engine?

We are thinking of taking an old valve from our spare engine and welding a valve stem to the top of it (ensuring that it is true of course) and use and old valve guide as a guide to keep the entire rig true in the bore. When that is set up, use lapping compound and a drill to turn the valve and slowly cut a new seat, ensuring that none of the compound makes it inside the engine.

Thoughts and comments please!

Regards

BTW....I am leaning toward getting an engine shop to do a proper job, if we can raise the funds.
