Fixing chewed hubs and keyways

Recommended Posts

I've done a few Hub repairs in the past. Thought I'd do a how to on the latest repair.

One of the hubs on bendy was a real pain to remove, this was the reason...

The hub had slid in and stayed that way for sometime, making a mess of the hub too.

The keyway in the axle was shot, the end of the hub shot too. The end to middle was ok and useable but with a longer key to replace the small woodruff key.

So I ordered a 1/4" end mill and used the lathe to cut a new one.

Firstly making sure the height was spot on by marking the centre of the axle, this needs shims in order to get the correct centre. The final score line can just be seen.

Then running the mill through in small passes to cut an 3 inch keyway.

Once the full cut was done here's a half together shot showing the hub, fresh key steel and axle.

There you have it, tools required - lathe, 1/4" end mill, 1/4 key steel, 10 mins of setup time and 20-30 mins cutting...

Nice job....*** maybe a bit off topic here but I just watched on the news about different establisments cropping up across the country where you pay a monthy membership and then the resources are yours to use....kind of like a Y only for creating things....so for 20 bucks a month you could have a lot of tools at your disposal....
