Thank you for making this video. It will likely help me to find an insert to get my own "project" saw going. I *think* that I may possibly have a saw similar to yours. Mine does have a model number plate on it, stamped 113.27521, but no serial number. I also have a newer (1982) model Craftsman 10" saw (113.298030) that comes with a serial number on the same plate. I'd like to know the age of my saw project, but I cannot find a lot of info about these earlier 113 series saws. It's probably out there; just requires some luck and diligence to find, I'm guessin'......
Thanks for the comments. There are old woodworking machine websites around. One is vintagemachinery.org. I've found user manuals for such things as my craftsman jointer, etc. Good luck going forward and I'm glad the information I gave may help. It's a shame that it's so hard to find parts for equipment that's so common. Every dad had a Craftsman table saw from the 50's through 70's so there's a ton of them out there. Generally they're built quite sturdy compared to today's. My saw is not great but serves me well. Thanks again.
