Attention Machinists

[CalG]

A tapered bore with a key way would NOT be a difficult group of features to produce. A shaper would make the keyway a breeze

Internally on a hub?

Where are you loudhornsrule? Did you find an alternate? How much would you be willing to pay?

My bad , I was thinking he needed a new spindle made !

I was ready to say that halfway thru' reading pg 1. :laughing: Could also be done on a mill or lathe (set up for shaper op) by any machinist. A keyway broach bushing could be cast of woods metal for a one-shot, too.

Tricky part would be duplicating the taper accurately with good surface finish. (1-2hrs, mostly setup) I'd expect most 'declines' to be based on cost/time to do both right.

Might turn an original shieve/sprocket into a hub and bolt/weld that to a bore in what's desired, depending on what's on hand that came off the shaft, of course. tog

I'm in north texas. It goes on a drilling rig that I am building. Probably just gonna weld a hub on there with a chain sprocket. I know I know Don't do it, but this is holding up my progress on this thing.

 

[ArtMech]

That would be a broach. Need a tapered plug to press it thru.

Right. This is exactly what I had in mind. Thanks for training. :drink:

 

[ArtMech]

Sorry. I was reading this and saw where you are from,and thought you mite be American living in Europe.

It would be too much honour for me. :confused3:

Have you considered sourcing a hub for the motor? This isn't exact but I'd imagine that they all have the same taper so it should be adaptable. Hub for wheel motor.

 

[loudhornsrule]

Yeah, I ordered a couple random hubs from them, and nothing would work. Thanks

 

[ArtMech]

What if you'd bring a motor to a well doing machine shop and ask them to make a correct hub for it? Before that you need to know and to tell them a required hub's diameter and its thickness according to its being in line with the other hub(s) or pulley(s). Most shops in my area have employed the constructors and/or technologists to correct an order. I'm sure you may find one, or even much better, around you.

A shop with a wire EDM could knock that out pretty easily. Xact has pretty good rates.
