Turning down 4 metal bushings by 60 thou for the guy who bought my Gingery Lathe
Difficulty Level (Easy, Medium, Hard, Insane):
Easy
Process:
I finally decided to sell my Gingery Lathe and the guy that ended up buying it had some metal bushings to turn down for his tractor so he asked me if I could do it for him on my Emco Maximat V10 metal lathe.
The dimensions were:
Length: 2.25"
Inside diameter: 1.00"
Outside diameter: 1.50"
He wanted the outside turned down about 60thou so I figured that shouldn't be a problem.
At first I attempted to put an arbor in my chuck and turn down a 60 degree cap on the other end so I could put some pressure on it with my live center, but the friction between the arbor and the bushing wasn't enough and it started slipping.
Luckily, the bushings had a hole drilled in them so I drilled and tapped a hole into my arbor, inserted a set screw to protrude just enough to catch the hole in the bushing and then turning them down 60 thou was a breeze.
