Hi my name is James and Im new to the forum.I've been in woodworking for about 25 yrs...started in trim and graduated to wall-units,custom cabinets and residential pre-finished libraries and custom wineracks.
I have been asked to make 2 kitchen chairs to match an existing set and need help in making a jig to route the butt & leg impression on the chair seat.any advice would be greatly appreciated.
Make yourself a copy router, there's plenty of simple versions on the web.
Set your wood up at the same height as the original chair and copy rout away.
Otherwise, an angle grinder with a roto-rasp attachment or #40 grit sanding disk.
