LAMP BUSHING

[morsa]

Thanks, Paul Jones.
My first thought was to make this bushings out of one of the round materials that I had in the shop: aluminum, brass, or polyethylene, but in the end I decided to reuse this discarded nuts, with the advantage that more than half of the work was already done.
I must say, my knowledge and ability to work with the Unimat lathe are rudimentary, as compared to yours.
