thanks for your reply . what i am looking to make is something that i can copy the back side of pistol grips on . A pantograph or a duplicator that will hold a dremel with a router bit.

I too have been looking for such plans. Small engraving for letters at 1/8", and .003 deep....

Martin Models http://www.martinmodel.com/ have the castings and they refer to Guy Lautard's 2nd Bedside reader for the plans.

Google 'copy router' and 'copy carver', they are just a little different to a pantograph engraver in that they lift the cutting tool according to the relief on what is being copied.

Most every pantograph copier I have seen for the home shop requires a model much bigger than the article being made, this has advantages but might not be what you need for copying existing pistol grips?

Try this site http://www.copycarver.com/ it even shows pistol grips being copied.


BTW, if making a size reducing pantograph it is useful to include a ratio of 2.54:1 which allows you to make templates using inch measurements and the finished product to be in metric.

In theory, on a manual pantograph, a larger model/master and smaller work-piece (achieved by reduction ratio) gives a job "smoother" and "more accurate" than the master. The reduction ratio can be set between pre-set limits.

The ratio between the master "follower" and the job cutter diameter/s has to be considered as well - unless a pointed follwer and pointed angraving cutter are used.
