6 1/4" Saw Blade

I bought an older circular saw and refurbished it. The problem is that it's a 6 1/4" saw and I can't find any blades that will fit it. It has a 1/2" square arbor, so I can't use a round arbor hole only blade and the blades that I've checked out that are 6" or less only have a round arbor and they're less than 1/2".

Thanks in Advance

What brand and model is the saw?

It may be obsolete.

Same as above

You have 4 choices:
Sharpen the blade you have
Find a square arbor blade...unlikely, or is it possibly a diamond arbor?
Make one from a round hole blade...possible, but difficult, hand filing and all
Change the arbor from square to round.....difficult to know without a photo..... bill

The answer to your question will only be as detailed and specific as the question is detailed and specfic. Good questions also include a sketch or a photo

I don't have a picture of it yet. It's a Shopmate 6 1/4" Clutch Saw. You can look it up in ads in Popular Mechanics 1955 issues. The arbor is 1/2" and it's square, not rectangle. I've been looking at a Freud 6" blade with a 1/2" arbor that might work, but I'll do more research for now.

Depending...

I don't think a 1/2" square peg will fit in a 1/2" round hole...
You can possibly use a 6 1/2" X 5/8" round hole blade on a 1/2" square arbor... You'll only add 1/8" to the radius of the blade, but a quick check for clearances will tell you yea or nay.
As long as everything is centered and there is a spring or clutch washer and flanged nut to hold things together it should work. A few small notches with a triangle file or dremel will allow a fit if it's too tight. Too loose won't work, it'll wobble. bill

I tried a 6 1/2" blade and it's too big. I'll have to use a 6" or smaller. You're right about the 1/2" round arbor slipping. It's not like I'm going to use the saw regularly, but it's a cool looking saw and I'd like to use it on occasion.

Thanks!

Found the ad!

Man this saw is ancient!
Interesting ads on the page and the next showing an interchangeable
spade bit boring bit. I was actually looking for this tool yesterday, and I knew it existed, made by Irwin or Power Kraft from Wards.

Page 354 has a Cushman Eagle ad...cool!?
page 340 has a Pull Gear speed reducer, which I bought years ago!!!
It's amazing how many of these companies have gone away!
Damn, this google books thing is addicting. __________________

It's a model 620. I have one that was my Grandfather's and two original blades.
