80/20 to Shaft

[Trent B]

I suppose that also leaves some room for clarification. Are you trying to couple the shaft and 8020 perpendicularly, or linearly.

For perpendicularly, the AndyMark hub would work. For linearly, you would need something like the shaft coupler with attachment holes I CADed up.

Maybe you should consider tapping a hole in the 80/20 and use one of these drive shafts

I found the answer !!!!!
This looks to be very promising. Hope to start building tonight!

Oh, and the Price is Right too! Come on Down!

many (all?) of those pipe clamps aren't designed for transmitting torque, but that doesn't mean that none of them are capable of doing so. The problem is that McMaster isn't link friendly, so I don't know which part you are looking at.

As a general note, when directing someone to anything on the McMaster-Carr website, do so by part number, not URL. It is the only way to show the person anything more specific than a broad category of parts.

This is the first thing I thought of as well. Seems simple enough.

Sorry about the link thing - you are right. Here is the part number:

Understand your concern about torque but this seems like it will work well for us. Testing will tell us the real answer!
