Can anyone help me with something. I have a real hard time making 2 of something the same. I don’t do enough to justify a duplicator. Tried making a salt and pepper shaker (not grinders, but actual shakers). It was obvious they were not even close to the same. Glad these were “try out” projects instead of for a customer.

Suggestions???

Some kind of pattern jig? Necessity is the mother of invention.

What works for me is putting it on paper first. A full size, inside and outside drawing. With that you decide when to do what, a step by step plan.

I don’t know about turning but for other duplications I make templates for my router which sometimes require more than one template. The repeatability is as good as the template setup!

A cool jig by a member here that helps you to duplicate measurements for various points on your turnings. Plans are from PW magazine.

Try to make a double pointed holder directly behind your lathe, and it must be on centre with both points like a headstock and a tailstock points.Then fit the original piece you turned, directly behind the new one you intend to make it becomes much easier to eyeball it that way also measurements are easier to transfer.I always turn to a cylinder first always never try to copy from square stock IMHO Have fun Alistair

You can use a contour gauge like this one: http://www.homedepot.com/p/QEP-10-in-Contour-Gauge-10032Q/202097525 It will allow you to make a pattern stick if your trying to duplicate something you have or already made.

Have your say...
