New Mini Metal Lathe

Just have purchased a new Micro Mark 16" metal lathe.

Have it set up on a new workbench with hardwood top. The lathe came out of the box set up ok, but I had to spend a fair amount of time and work cleaning the protectant off and re lubricating. Followed the following link. Still needing to do some of the other modifications.http://www.mini-lathe.comI turned the button shown below as a test. One of those canvas chair that we take to picnics etc had lost one of the special threaded buttons that hold the canvas on the metal chair frame. I could not find one anywhere so I turned one out of some 3/4" aluminum bar. I worked very well. Chair is repaired and sits well.

In short had use several lathe techniques to make the item. Started facing the low portion flat. Turned down the smaller lower diameter. Bored and tapped the 5/16" NC18 hole for the bolt to attach the canvas. The piece was then parted off the aluminum rod and remounted in the chuck with the top out. The top was then turned down and tapered by eye. No special tools. The top was then dressed and polished with 80 grit, 120 grit, 220 grit and finally 400 grit paper. Looks pretty good and works well.
