Lathe duplicator/copy lathe query

lundi 22 juin 2015

Hi Folks,
I've seen occasional old 'duplicators' that can turn cabriole legs, and other non circular items. I've seen occasional new home-made versions - one with an angle grinder using a 4" circular chainsaw carving type blade, and one using a 6-1/2" circular saw - each moved along from left to right drawn by a nut on a bit of long threaded 12mm rod.
There was a rocker affair that has a wheel that followed a slowly rotating original sample, and that allowed the timber blank or the saw blade to move up and down in and out of the blank as it slowly rotated.

I was wondering if anyone might have one they'd care to share some design tips from, as I'd like to make myself one?
Thanks in advance!
Ian
