Will A Taiwanese TS Have A Metric Arbor Nut?

Aren't all TSs made in Taiwan. All hobbyist/pro stationary tools?

You should be able to buy individual wrenches that large at HD.

A whole set of HFs is probably cheaper.

The nut on Unisaw is a 7/8" is equal to 21 mm, so would take a few in that range.

You mean "buy". I don't have any metric wrenches that large. Some sockets, yes, but I don't if I'll be able to get them in there. Never seen the saw.

I'll just buy a set before I go. I don't want to shop while I'm there, I want to cut. ;-)

Having looked at Pro-tech stuff that came up on google, mind your digits please.

You're not going to get a normal wrench on a Unisaur arbor. Unicorn horns are easier to come by, too.

I have offset closed end 7/8 actually two of them, and a bandsaw blade cutoff that is custom made by my dad. If a unicorn has two horns it is a gazelle right.

Is she turning the wrench in the _right_ direction?

Assuming that where you are going is near a hardware store, buy a wrench at that location.

Past that, what brand? Can you google a parts schematic of the parts and wrenches of that particular model?

But my Taiwan SS saw uses 32mm/1.25" wrenches on the nut side.

LOL. I recall working with Swingman several years ago and removing the arbor nut on his Unisaw, pre 2005. Small, very thin, compared to the one on my Jet cabinet saw. Then he saw the arbor nut on my SS and his eyes about popped out of his head.

A 1.25" wrench is required and it is about triple the depth of his.

First thing I thought of. A little hard to determine if it is a direction thing or a size thing.

Many nuts/bolts are difficult to remove with a crescent wrench even if it fits the nut.

Based on what I was told, yes. Arbor enters blade from left, she (and her boyfriend, a concrete contractor) were pulling the wrench towards the front of the saw. We even talked about it on the phone.

I've seen the saw. It's well used. No one knows when the blade was last changed or how tight the nut was tightened. I'll know more tonight when I put my own eyes on it. It could be just a leverage thing. Her boyfriend didn't have any "large" tools with him, just her 10" crescent.

As I noted in my response to Scott. I'll know more later tonight.

The brand is in the first line of my post ;-)

Pro-Tech. I don't know the model number, but I (and she) weren't able to find a manual for any Pro-Tech table saw. The closest we found was other people looking for a manual.

As I mentioned in a couple of other responses, I'll know more tonight when I put my eyes on the saw.

The nut ALWAYS tightens in the opposite direction of the saw blade's rotation. In other words, it loosens in the direction of rotation. Block the blade with a bar in the gullet of the blade tooth and turn the nut in the direction that would cause the blade to attempt to cut the bar

I assume that info is just for general knowledge for anyone lurking in the wRec.

Those of us that have been around and using table saws, miter saws, circular saws, etc. for decades are familiar with how to change the blade.

The question was about the size of the arbor nut in a Taiwanese TS, specifically a Pro-Tech.

These saws were sold by Sears, at least for a while. Sears often has the documentation, even on old stuff, even if the say is not branded by Sears.

Thanks.

I'd need to find a model number that works in the Sears system. Searching Sear Parts Direct with various forms of "Pro-Tech" returns a couple of parts for a treadmill.

I'll be in front of the saw later this evening. Maybe the solution is as simple as what I have in my toolbox. I'll know soon enough.

Vintage Machinery may also help.

Bring a digital caliper. Even one from Harbor Freight. That will settle the issue as well.
