Wanted: Spline coupler

[Perry Kitson]

Try True Gear and Spline in Cambridge. They may be able to help, or point you in the right direction.
It is a rather small involute spline you are looking for, cut with a broach, so something that is not conducive to small numbers for production.
Also try Hub City or Motion Canada. I used to get some odd ball spline coupling's through Motion while I was still working.

You can also get a guy with a "wire cutter" to cut an internal spline of any size out of any material, quite an easy process, simpler than broaching, and very accurate ,Cheers Andrew.

Many hydraulic pumps use a splined shaft. If you check with a shop that deals with hydraulics you may find something that will work.

Thanks for all the leads, I have to admit I have not heard of the wire cutter technique Andrew, perhaps there is a video on line.

Might also be known as "Spark Erosion" or "Electrical Discharge Machine" in North America.
