Re: Tool rest locking handle question

Banjo locks are normally but not always different than the tool post lock. Most of the more modern lathes have an offcenter cam kind of system to lock the banjo. they usually have a nut of some sort under the lathe to adjust the locking mechanism which changes the location of the handle when it's locked. Some are easier than others.
Most tool post locks are just a bolt attached to a handle that screws in against the tool post to lock it. Most lathes I've worked on have a spring loaded adjustable handle. The new Powermatic 3520C has a split cam that is pulled against the tool post and is very positive. A definite improvement over the older system. The Powermatic 2442 has a split casting that is squeezed together to hold the tool post. Another good system.
