A little more work today. I went to The Steel Yard for some material for the swingarm and the frame extensions.
Did a little more soda blasting. Went through three boxes of baking soda and made a little progress.
I also finished up the sprocket carrier for the lathe.
Bolts thread in from the back, a nice tight fit.
A test cut; smoothing up the already ground sprocket. Success!
Like the sign says: "Das machine ist nicht fur gerfingerpoken."
