Move some things around to get at the mill. (will be a welcome day when I get those counters out of the shop)

Using tapered pins to tighten up the worn splines on the steering arm.



Can't quite see it in the picture, used a v-block between the spindle and the 90 degree plate or what ever you call it. Made a spacer to hold the arm at the height I wanted and the clamps hold it firm and square.



Drilled down 1 1/2 inches then reamed for the pins. Have to cut about 3/4 off them to stop them bottoming out, my next size smaller tapered reamer would leave 1/2 inch of hole below the pin.
Going with 4 pins per spindle.

Ya didn't watch the video I made on grinding drills for use in plastics and brass. All you need to do is eliminate of the positive rake on the drill and it won't pull in on you.

That's gonna be a happy tractor (and owner) when you are through.

Yah I did watch it, just didn't implement what I learned till after it grabbed.

Finished them up this morning. Was pleased with how my drilling followed the gap, was worried it would steer into the softer cast arm.
