I am looking to make a couple of tables that raise and lower. Each would have a handle at one end, which when turned lifts or lowers the top. The proposal is to use 2 screws linked to the handle shaft by a 2 pairs of miter gears.
I am having trouble finding an econmical source for suitable miter gears. They do not need to be high quality or extremely large, but need to accept/have up to a 3/4" diameter bore. They could even be a strong plastic. Anyone have a suggestion where I could find something suitable; preferrably in Canada?
