Re: Hex Axle- How to
You can get a 1/2 hex broach for just over $100. We bought one and a 3/8ths broach and it's one of our more useful investments. Certainly not the most vital, but it's good that we have it.
We have just bought hex stock from McMaster or other cheaper sources rather than machining our own shafting with no problems. We don't step hex, but we never have found a time when that's been necessary thanks to AndyMark hex bearings.
All you should need to run a hex based anything are snap rings for retention and the occasional spacers. No keys or awkward retaining rings to get lost.
