Setup for outer side of lid The height of the metal base will vary according to the size of the lathe Garry uses a high speed, tool steel cutter and holder mounted on a cross-slide table (See close-up below) |
Close-up view of cutter in action Garry grinds the cutting tool to a dovetail shape - wider at the top than the bottom |
This is the setup used to make the parallel straight cuts on the inner side of the lid. The table / jig arrangement must be designed to put the cutter very precisely at the height of the lathe's main axis.
IT IS IMPORTANT TO REMEMBER TO CUT PERPENDICULAR TO THE GRAIN OF THE WOOD
OTHERWISE THE PIECE IS WEAKENED |
Close-up view Note the wooden chuck Garry has made and the brackets used to secure the piece |
Using a template to check the inside curvature With the die grinder set up accordingly, a constant depth of cut can be maintained |
Another setup using a smaller, air-powered die grinder |
Different view of showing the pivoting action The radius for cutting the grooves is on the same vertical centre as the rotary table΄s horizontal centre |
