Friction Wheel on Hammer A3/41


 

I was using my A3/41 in planing mode yesterday when I started hearing an unusual noise. ?I removed the inspection panel and saw the rubber (or similar) tire had come loose on about half of the circumference of the wheel. ?I’ve attached (I hope!) a picture.

I’ll call the Felder service dept on Monday, but wondered if anyone has had experience trying to re-glue the tire to the wheel. ?

No picture… but as far as I know you can buy a new wheel from Felder or get them recovered. Others will know where to recover, I bought new.

Here's another try at inserting pictures. ?The closeup shows the divot missing from the tire. ?Not sure how that happened. ?I estimate I have under 10 hours on the machine. ?

That looks like the feed was left engaged and it eventually squeezes a divot into the urethane on the wheel. Then as the drive wheel comes around to it, the wheel slips a bit, causing more heat, which either cracks or melts the wheel starting at the divot and spreading until failure.

Thanks, Brian. ?I had the same thought, and feel 99% sure that when I packed the machine for the move from California to Louisiana that I disengaged the drive wheel. ?At any rate, I cleaned the wheel and tire with alcohol, glued it back on with CA glue, and then shaved the “divot” so it wouldn’t thump on every rotation. ?Seems to work okay and I hope it’ll last until I can get a replacement tire or wheel.

Great repair, hope it holds up long enough for you.

So how do we disengage the feed?? I have had my machine a long time with no problems but I usually just shut off the power.

The levers on all the machines that I know of, have a neutral position. You go one way for high, one way for low, and there is a notch on mine for neutral.

All these folks saying they don’t disengage the drive, awfully lucky… If you by chance leave it engaged, before you start it up, disengage and leave it set over night, then listen for lumpity-bumpity when you do engage and give it a chance to smooth out, as the urethan warms up from running, the noise will usually disappear. There is no effect of the cutting transmitted to the wood.

These wheels are meant as the weak link in the planer, if something jams and goes wrong, the urethane gets toasted instead of breaking shafts, sprockets and chains.

Thanks Brian,
So you’re saying there won’t be permanent damage?

Maybe… maybe not. I know it is surely better to leave them disengaged.

The good news is that Felder service dept had the part, and the better news is that it was under $40. ?Should be here by Friday. ?The wheel I repaired is working so I'll keep using it until I hear the "lumpily-bumpity" Brian mentioned.?
