The biggest steel part ever turned on DB/SL.

Tinkerer22 All Messages By This Member #64131 I needed to reduce a piece of thick wall steel DOM tube by 0.5 mm to about 38 mm. It's 153 mm long. In order to fit it on the lathe I retracted head spindle past the stop screw. Then I made a hollowed plug fitted into the end of the tube to accommodate/recess live center of the tail stock. The part barely clears the cross slide.? Finish leaves a lot to be desired, but it did the job.
Charles Kinzer All Messages By This Member #64132 That's pretty impressive.? It's always interesting to see somebody able to use a machine FAR beyond its intentions.? You just wouldn't want to have to be doing that every day.? But for a one-off project, usually if there is a will, there is a way. Today, I was cutting some 0.1 x 0.25 inch TUNGSTEN bar (about twice as hard as cold rolled steel) on a cheap little hobbyist table saw (similar to the little Proxxon that sells for a little over $100).? Really meant for wood or plastic and maybe thin brass or aluminum.? I think the Unimat "table saw" attachment must be similarly specified.? But when using a diamond saw blade it worked fairly well.? But the diamond saw blade was getting dull after cutting about 2 dozen cuts. Charles E.
