Topic tags/keywords: jig question resource tip trick router

As I was lowering my jessem mast-r-lift ii 02120, the crank insert piece began rotating freely after the router dropped about an inch. As I kept cranking it the insert came out of the router plate. I watched a couple videos and looked up the manual but couldn’t find much. Has anyone else had this problem ?

I had a JessEm product failure in order to fix it was over $100 to fix. Poor design and I have no respect for JessEm

Check to see if the split nut on the main screw is loose. It’s there to allow you to minimize backlash, but if it comes apart, the crank won’t lift the motor.

The split nut was so gummed up with grease and dirt that it was borderline welded to the threads by normal routing debris. I guess to combat this I’ll have to position a shop vac to suck as near to the underside of the router plate as possible. I wish the rod would come with a dust jacket similar to the ones on old school dirt bikes.

If it happens again then I’ll try plumbers tape and if that fails then my last resort will be loctite 640 sleeve retainer metal adhesive. According to saw stop- after a couple years their lowering trunion shaft has a brass bushing that hugs the actual shaft but pops out. Basically liquid welding.

On the other side of the spectrum, I have used JessEm for years and the company is one of the few places that still makes quality and knows what customer service is about. I upgraded from the Mast-R-Lift to their complete router table set up -WOW!!! not cheap but top quality.

Email them and I’ll bet you hear back from them in short order.

Called jessem and sent them a quick video I made of the problem. They sent me a replacement threaded rod, backlash nut, slotted nut, rubber washer and alignment pen all for free. And it all got to my shop in Texas from Ontario in 2 days. I have no complaints of jessem anymore.
