I have a SB vertical milling machine in the basement. The front handle is a spoked wheel approx. 6" in diameter with a crank handle. I keep hitting the crank handle when walking by the machine. I thought of reversing the wheel but is held on with a pin and changing it back and forth would be cumbersome. The crank handle spins but is pressed into the wheel. I thought of replacing the crank shaft with a threaded one that could be removed and replaced easily. Thought I would consult with the group to see what fixes have proved successful. Any recommendations? Thanks Paul

Hacksaw it off?

I saw a steering wheel spinner on something like that recently.. it had a reclining lady picture in it.. I thought that was funny.

Truck stops has spinners.. if you are used to actually driving tho, they bang your elbows.

The most ingenious solution that I have seen had a handle that folded into the wheel. Just unfold push in and go. I have seen similar handles in the last issue of digital machinist on one of the plug and play kits, so they have to be available somewhere.

In regards to Brian's post above, McMaster Carr has fold away handle hand wheels. Just search for hand wheels and you will find them.

Paul, I have a similar wheel on my horizontal mill.
That damm handle stuck out just perfect to nail you right in the thigh and give the ever popular charlie horse.
The one on mine was pressed in as well. I put a piece of pipe on it and slowly rocked ot one way then the other till it loosened. A few more and it pulled out.
I sorta miss the handle but don't miss the big ugly bruises it made.
"Someday" I'm going to make a short ball type handle like you see on steering wheels.... or after you make a folding one, i'll just copy yours :D

Two suggestions:
Pull the handle out and make it a slip fit so it can easily be removed and misplaced. You can also install spring loaded ball bearings in the shaft that engage a groove in the bore to hold it more securely but still make it easily removable for misplacement.:D

Remove the handle all together and make a splined hub to accept a crank handle like those mounted on a Bridgeport.

I came up with a solution to the misplaced handle in the first suggestion, but it's kinda hokey so I'll keep it to myself unless you decide to go that way.

Thanks for the great ideas. A folding crank would be fine-now to find a way of doing it! Paul

I was driving down the road today when a shiny object on the shoulder caught my eye. I stopped for it, and what I found was a rather heavy-duty looking folding motorcycle foot peg, and I immediately thought of this thread.

Paint the handle bright Orange or yellow . Then you will see it. I had the same problem till I painted mine Red.

Hi Bruto.

The perhaps best idea is to use a captive spring-loaded ball as in a say 1/2" square drive on some socket sets.

In your "foot peg" would be drilled part-way through to suit the the ball and spring which would be let into the square and then retained with a hammer and centre punch or wad punch. The "forks" would be indented with a "shallow" drill.

That's the principle. The specific application can be adapted from that.
