Title: Bohning cresting lathe clutch slip
Post by: Stumpkiller on February 14, 2011, 10:01:00 AM
I was cresting up a batch of Douglas fir shafts this weekend and my old Bohning lathe was "stuttering" and the arrow wouldn't spin about 25% of the time.  "Time for a new rubber gasket" says I.  Well, the new gasket was just as bad.  Harumph.  I could twirl the arrow in my fingers with barely any resistance.  The gasket was twirling inside the groove in the arbor with plenty of clearance.

So I set back and pondered life and then started poking through junk bins.  I came up with a solution in the form of the wire from a Chinese take-out box (malleable iron wire - yes. I'm a pack-rat).  I bent it into a circle with round jaw pliers and fashioned a loop on either end so I could squeeze it in and then expand it with the plier jaws (it's not springhy enough on its own).

A cheap fix that had me back up and running fine.

Note - My Sharpie pen cresting with pecan stain above and yellow leather dye below.  Metallic highlight lines will be added after the polyurethane finish

Thanks for sharing Charlie, I've got the exact same Bohning crestor. I haven't had this problem yet, but at some point I probably will so I'll keep this little trick tucked away in memory.

I'm also a pack rat, I've been working of reducing some of my clutter but I have a hard time throwing anything away that could prove useful someday.
Problem is, as soon as I toss something out invariably I will need it 2 days later.

Thanks for sharing Charlie. I have the same problem, the replacement rubber gasket is not available and the gasket that was close in size does not work. I think that I will try to build a similar spring and use that to solve the problem. Thanks again for sharing!
