Crank handle repair. How?

[berntd]

Hello,

I am looking for some advise on how to re-attache the handle back to the crank.

It originally had a one way clip in there but that did not survive the rust attack.

What have others done?

If I'm not mistaken, there was a springy piece of steel with with a "C" cross section that was located in the groove. The "C" could spring open enough to pass over the larger diameter at the end of the shaft, then snap into the groove. While in the groove, it's outer diameter would be large enough to create a press fit with the knob. Pushing the knob over the "C" would compress it enough to adequately retain the knob, but not so much as to make the "C" tight on the shaft.

You need to find some tubing with an inner & outer diameter that will do as I describe above. Then, cut to the correct length, slit one side of the tubing and push it over the shaft. After slitting, you may need to pry the "C" open enough to make it fit snug in the knob. In other words, some adjustment may be needed.
Might also slightly chamfer the end of the "C" that the knob will have to press over, in order to guide the knob onto the "C" without carving up the hole in the knob.

You don't need spring steel for this. It's not going to take a bunch of press fit to keep the knob on. Just has to not fall off, and you're not going to tug on it. There may even be some hard plastic tube that might work.

I think the clip you need is called an "e clip", which are available at Home Depot or auto parts stores. Take your crank with you to find one that fits the diameter of your crank.

This is the bit you need. You are welcome to it, and if you are willing to reimburse for the postage (I'm in England) I'll be happy to send.

Phono48,
that looks exactly like it.

Thank you for the kind offer. I will keep it in mind if no local solution can be found..

OK, I see how that works... You slide the crank through the handle, put that gadget around the narrow part of the crank, push it down into the handle and the prongs keep it on.

Basically, yes. You first put this little clip round the narrow part of the crank. with the prongs pointing away from the end of the crank. Then as you push the wooden grip on, the prongs are compressed, but when the grip reaches the correct position, the prongs open up and dig into the wood, so preventing it from coming off.

I do not think there is an internal groove. The spring force just makes the sharp spiky prongs dig into the wood.


I decided that mine cannot be fixed that way since all the rust and a huge crack has taken it's toll on the handle with the hole way big and out of round.

I repaired the crack with epoxy and made a metal bush for the handle so it can at least fit on the crank properly.

I decided to keep it on by drilling it and using a pin made from a welding rod.
The pin goes through the handle near the outer edge of the crank groove.

This is removable if need be and hardly visible.

Perfect solution I have done many times and if you repaint the handle black as it should be totally invisible
