Jet JWTS-10JF table saw missing both trunnion crank wheels (up/down, left/right)

Have a JET JWTS-10JF that was missing both crank wheels and parts are no longer available. I used crank wheels for a Powermatic 64A.To modify the Powermatic wheels:
1. File a slot in the back of the wheels to engage the pin on the shaft that cranks the trunnions up/down and left/right. Otherwise you must replace the 3x30 spring pin with a 3 x 25 pin. Those are a press fit, and you do not want to bend the shaft.
2. If you use a JET handle, instead of the more expensive Powermatic 64A handle, you will need to carefully bore a hole in the back of the wheel, just deep enough to attach a nut to the handle\'s threaded shaft. Were I to do it again, I would buy the Powermatic 64 handle for the Powermatic 64 wheel, even if you have to wait a month for arrival.
3. The JET locking knobs were a perfect fit.
