I have one of those
Last week my Mom bought me a Craftsman circular saw (model 315.10864) mounted to that exact same table for $10 at a secondhand store. It's in good condition, so we figured we couldn't go wrong for ten bucks. I am totally new to circular saws, and the only thing I knew was to make sure it's lubricated, clean, and the wiring is in good condition.
I just figured out how to take the saw off the table so i could clean all the sawdust off, but I can take some close up pictures as I put it back together and share them. 'm not sure if this is the complete table though. The saw has a way to adjust the bevel of a cut (I think this is called a scale- but please correct me if I'm wrong) but it is firmly stuck at zero degrees and 'm not sure how to loosen it correctly. The table itself does not have the bevel adjustment that appears in pictures of similar setups.
I have figured out how to raise and lower the depth of a cut at least. The wrench that is used to change the blade was missing, so I'm not sure if I can use crescent wrench, or need a specialized tool. Both the table and the saw are pretty heavy so I hope I don't need to take the saw into a store to fit it.
There are 5 triangular shaped braces that fit over 5 bolts on the underside of the table that can be turned to fit different brand of saws and tightened into position, so no need to drill into the table. I noticed that mine have some slight bends in their shape but I don't think their strength is compromised for future use.
