Saw Arbor and Spindle have become incompatible

[bushwork]

Last spring I bought a Model 510 that was originally purchased in 1986. Being new to SS, I installed the saw blade with arbor already attached by the previous owner and tried a few saw cuts. All is well so far. Later in the day I decided to try the bandsaw, but a spinning saw blade was not a good idea so I tried to get it off. No such luck. With great difficulty, it came off, but would not go back onto the spindle and another blade spindle combination would also not go onto the spindle. The set screw was properly aligned, there was no rust, I found no burrs, and I used steel wool to see what that might remove. No luck. Old posts from 06/09/08 suggest rust/corrosion and I can rework that per the video recommended last June, but is there any other possible explanation? Thanks for your help. Don

Try cleaning both the inside of the saw arbor opening and the shaft on the headstock. It may take some sanding cloth to make a difference. I have used a 5/8 wire brush that plumbers use to clean copper fittings to clean out the arbor. I am sure that is all it will take since it was once on the shaft.---Good luck---Dave

Welcome to the forum. judaspre1982 gave you the same advice as I would. It should do the trick.


Glad you joined

Notice the end of the spindle. The flat is tapered, but does NOT extend all the way to the end of the shaft. When REMOVING an arbor or any other device from the spindle you MUST back the set screw far enough to clear the end of the shaft. If the set screw is NOT backed out far enough it will hang up on the shaft end. Any slight burr that is created by trying to force it off the shaft with the screw not backed out far enough WILL cause difficulty in attaching another. Clean up the shaft if need be by judicious sanding etc. Try another arbor(by itself without a blade) on the shafts at the other end of the headstock. It should easily slip onto any of them. Once you know you have a 'good' arbor, repair the spindle shaft until IT JUST FITS. Do NOT over do this.

BTW The setscrews should have a flat bottom, not cupped or serrated.

Thanks for your input. SS recommended filing the spindle--a bit severe, I thought. I will try the methods that have been suggested.

Filing is ok as long as it is done sparingly, on the correct area, done so as to NOT alter the original round shape. i.e. file ONLY that which should not be(burrs etc.).
