Gents,
I find, that one of those retractable tool setups, an invaluable aid.
I saw the principle on the "Hemingway Kits" website.
http://www.hemingwaykits.com/acatalog/Retracting_Tool_Holder.html
The principle is almost silly in its conception!
I have "improvised" one to try it out, and now, it is on my to do list
to make
a proper one, by next spring. It is especially helpful on the more
economical lathes, where
a dead stop system is difficult or impossible to use.
It is a project, that can be adapted for all lathes, and will help anybody
to overcome the fear, of not being fast enough, in retracting the
cutting tool, and thus creating
bedlam, if the cutting tip, digs itself in the chuck!
