Re: IFI Traction Wheel stationary?

we use 7075 for all our shafts (We had one this year out of 7068, but it had a gear hobbed onto the shaft itself). We use round stock and then mill the flats for the hex onto it, though.

We used a 2024 hex shaft for our spool to lift our elevator this year. Wouldn't suggest it for a driveshaft or anything under a ton of load, but it worked well for the application we used it.
