I’m not sure if IMHO is the right forum for this type of question, but since I’m looking for opinions and not facts, I figure I’ll start it here.
I have an old table saw that I inherited from my grandfather. Even though it is 60 years old, it is still a great table saw with one minor flaw. I can’t lock the blade height adjustment and the blade tends to drop when I try to cut dadoes and rabbets.
I am planning on building an all in one cabinet to hold a bunch of the table mounted tools I inherited from him. Since the height adjustment hand crank is so far under the tabletop, I figured I would extend it out so it will be easier to locate. It would probably also need some kind of support to keep it from bending if something gets caught on it.
The blade height mechanism is a worm gear, as seen here. The hand crank attaches to the worm screw with a set screw in the collar of the crank.
I figure that I should be able to get an extension rod that would attach to the worm screw just like the crank does and will allow the crank to be reattached at the other end. I figure I could have this extension rod go through a metal collar or ring with another set screw that can be tightened to prevent the mechanism from turning and lowering the blade while I’m cutting dadoes and rabbets. That collar would also provide support to prevent it from bending.
My problem is that I have no idea how to get that extension rod and locking collar. It would have to be made of metal and I have no metal working skills. I don’t even know what to google for. Would a metal fabrication company do something that small and insignificant? Any one have any opinions on a ballpark cost for something like that?
If anyone is interested, hereis a .pdf of the owner’s manual. There is a schematic on page 2. The worm screw that I would want extended is labeled as “27”.
