When you do not have either a lathe or a mill its amazing what you can do with a drill press.
I needed some custom pulleys for the cable steering for my lowrider bicycle so I made them.
Cast two pulley blanks
roughly cleaned and drilled for a bolt, the lock screw prevents the pulley slipping when turning.
When all the turning was done I cut the boss from the disk using a hole saw
Set up in the drill press with an epoxied chuck and faced it off with an old file ground to an edge. I clamped a block to the table to brace the turning tools against, just like wood turning.
Then turned the dia to size with the same tool.
For the pulley groove I ground a rounded tool from an old rat tail file.
These were made nearly 7 years ago and are still in use on the bicycle today.
