Hello,
I need 3 shaft couplers that go from 1/2" to 3/4".
Bore A: 3/4"
Bore B: 1/2"
Outter diameter: 1 1/2"
Length: 2 1/2"
Material: 6061 Aluminum
The depth of each bore should be equal, meaning 1 1/4" for each one, nothing special needs to happen in the middle. I plan to drill and tape the set screws for this, so no need to worry about that.
Tolerances should be pretty tight, although i'm not Nasa or anything. Obviously this should be done on a lathe, i tried doing this myself with machineable-bore couplers from mcmaster, and using a drill press, but they are off a tiny bit and make the machine do horrible things, so I need to them to be made well.
Or if someone knows where to buy these, I can't for the life of me find any supplier that has these, most only step 1/8" of an inch, not a 1/4".
thanks,
Ross
