Re: pic: 973 wheel hubs

How are those different from the AndyMark hubs? They look pretty close, but I'm assuming you made them for a reason.

Re: pic: 973 wheel hubs

Re: pic: 973 wheel hubs

It is hex broached using a 15 ton hydraulic press if I'm correct.

Re: pic: 973 wheel hubs

They are quite similar to AM hubs except for the hex which is a 7/16 hex.
We HAD two easy process options for making these.. HAD being the operative word.

Normally we could have set these up on our Haas CNC milling center OR our Haas CNC toolroom lathe .... but alas our shop at El Camino College is undergoing "reconfiguration" to make room for a new Haas VF-4 vertical milling center and a Motoman industrial robot station [which is being installed inside of an 'Ultimate Fight Cage']. With most of our CNC machines offline in the shop we did the hubs the old fashion way on a manual lathe and a Kent mill. The hex broaching was done on a hydralic 50-ton press which proved great exercise for those involved.

Hopefully next year AM will offer these HEX hubs in a 7/16 size and save us the trouble of making them.

Re: pic: 973 wheel hubs

They look good.

You know, you could have just bought the ones AndyMark offers with the 0.25" bore and just bore out and broach.

...we needed 1.500" to make getting the retaining snap ring on the hex shaft easy to get on and off that mates thru this hub...

Sometimes you have to look ahead and think about "feasibility/easability" of assembly and repair when designing 'stuff'.

And 50-ton press for 7/16 hex broaching was not overkill... it was the right tool to make the task easy and predictable. The 10-ton hand arbor press we started with made the same task "interesting and challenging". But I must admit there was more fun doing it that way....
