I have the same duplicator, Its pretty nice
Did you say you mounted it to the BACK of the lathe? If thats the case dont you have to reach over the turning stock to run the duplicator?
Id like a few close-ups (if possable) or that templare holder you made. Usually I turn one origional by eye and then when Im happy with it use it for the master. It would be nice to be able to use some plexiglass templates.
