Hey guys, two things today.

First, the table saw arbor on my '55 SS is absolutely rusted solid and I need to change the blade. Any good advise on how to do this and save my fingers from getting shredded if a wrench slips while cranking on the nut?

Second, I can only get 5/8" arbor blades locally and can't afford to buy an SS blade, let alone wait for shipping. Would it not be a good idea to use a step drill bit to widen the 5/8" arbor to the 1 1/4" size? That seems like a reasonable option to me but I don't want to ruin the integrity of the blade either.

Hi, I just picked up a 5/8" smooth-bore arbor with 2 set screws at Busy Bee (Canada) for about 8 bucks. You should be able to find something similar.

About the rusted-on arbor... much WD-40 (or your favourite stuff) and patience.

Use P B Blaster and let it soak awhile. To help save your knuckles, wrap the blade with a towel or put a piece of cardboard on top of the blade and under the wrenches.

You can get the blade rebored to the needed size but I would not recommend doing it with a step drill. I have no experience just an abundance of skepticism for doing such things. Balance is the issue I would be concerned about.

You can buy Shopsmith arbors for 5/8 bore blades. Just make sure it is the right one for you table.

Yeah, but time is no on my side and I can't wait for shipping right now.

I'll see what I can find semi-locally and go from there, but I might attempt drilling the hole wider on my saw once I get the old one free's up. I have a good drill press with laser centering, so I'm sure I can handle the job well enough.

In my view, I think you're asking to hurt yourself trying to expand the bore from 5/8" to 1 1/4".

I highly recommend soaking the rusted piece in a product called Evaporust. It is available in one gallon jugs at Tractor Supply Company and Harbor Freight. Here where I am, it is significantly cheaper at Tractor Supply.

Completely submerge the part in Evaporust overnight and you'll be amazed at the difference. I have seen Evaporust do overnight what PB Blaster could not do in six months. I am not exaggerating. It is easier than electrolysis.

After soaking in evaporust over night, you will stop thinking about getting a new arbor!

Do keep it enclosed. It will evaporate!:eek:

You did not state what the rusted arbor size is.

If 1 1/4 from 55 do realize the nut has a left hand thread.

Please Please Please help me get a manual for my fathers Shop Smith ER. I am desperate::)
