/diy/ - Do It Yourself

I got this Craftsman circular saw for cheap at a thrift store. I took it all apart, cleaned and regreased everything. It works great.

However it has two quirks that are making it impossible to use:

1) Has some weird fucking arbor size like 3/8" that I don't know how to find anywhere
2) It's a 7" model, not 7.25 like every other saw blade out there

It's definitely an old model. What the fuck did the saw industry do? Or was this something you could only buy blades for through Sears?
I really want it to work after spending a couple hours getting it in nice working order.
