Charlie Gavask installs hard valve seats in 444MH, circa 1989
email Grant

The engine had been in my '31 Model "A" Fordoor for 1500 miles before we installed it in Howard's Pietenpol Air Camper N444MH.

Before flying with a passenger, we decided the old four-banger would need hardened valave seats. Our friend and Model "A" expert Terry Oberer told us Charlie Gavask could install seats, so we all (Howard, me, Terry & Charlie) met at the hangar, and Charlie did the job. Here are a few photos I took that day:

Notice the one-blade cutter above. And Charlie just drove 'em in with a hammer on that cold winter day.

Recently (12/16/16) on youtube I found more sophisticated tools being used to perform the same task; made these screen shots:
