Caster repair

[Roger Jolly]

Hi John,
               Here's how we do it, with a Forsner bit.

We cut two pieces of 5" square 3/4" thick plywood, and glued them together.
Take a 3" Forsner bit and drill a hole through the wooden template.
Tack the template with two 2 1/2" nails to the toe blocks so it is centred 
over the old holes.  The Forsner bit will now cut safely without chattering.
Use the template to guide the bit as it drills out that nasty shaped hole.
This will also work with some Spur bits.

Regards Roger
