Drilling holes to get casters on straight in a chair5/31
Who has a process or a jig to get holes for casters drilled straight in chairs?
There's no right angles and even though I have a drill guide attached to my hand drill there is no method to get a 'drill press-straight" hole to the floor made.
Chairs are oxey things to maneuver. I wondered if anyone had a solution for a chair that is already built.
It seems like you could make a platform larger than the area of the four chair legs. Say a piece of plywood, that you could set against the bottoms of the chairs four legs, all at the same time. You could then set a guide of some sort for the drill, to the plywood. Since the plywood would establish the same angle as the legs to the floor surface, any drilling would be at the correct angle.
On my chairs when casters are requested, I made a clamp on jig, that matches the 5x5 degree splay of my design. The jig has a bronze bushing with the ID being the drill bit diameter.
This idea could be incorporated into wmsuber's platform idea.
The platform idea has merit, Still, lining everything up on an angle with a completed object still seems a problem.
Backtracking a bit, this cannot be a new issue. What does a professional company such as Sherrill (where I actually bought a chair with casters of the type "club chair") how do they get the hole drilled straight and at what part of the operation?
It's simple when the legs are just pieces of wood that one can clamp into a fixture on a drill press.
Once they are part of a chair you have to think before you drill - that's not easy.
