 First of all, please remember that while we often focus on winning the Chairman's Award, that it is the effort to win that matters. No one "loses" RCA... if you've worked your butt off all year in the spirit of the award, then you've already won before you even get to the regional. - dtengineering [more] |

Finished last night, but these were started on Saturday, and were the second order we have made. 6 were made last week, in addition to this set of 10. The center IS hex broached. (the CNC lathe at our shop was disconnected, so all the hubs were lathed manually)
Your welcome Adam... lol

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
is the hex slot milled or is it a specific machine?

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

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.

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.

But yeah, hex broach the way to go.

....despite the fact that the dimension from hub shoulder to hub shaft terminus is only .820" on AM hub... too short for our application...
...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....
