If it's like this one a new table plate is easy to make.
Get a 8x8 inch 1/8 inch 10ga plate and use a saber saw to cut a blade relief and drill and counter sink the 2 mounting holes. The holes in the saw should be 1/4"-20 thread, I just cut down some Philips drive flat head machine bolts.
Another semi upgrade for one of these saws is to use a heavy spring from the back of the motor mount to the frame to add tension to the belt. the thumb screw tensioner tends to bend and let the belt loosen up. The spring will allow the tension to be there but if the saw binds up it will allow the belt to slip saving the blade.
I also have had poor results with the commercial blades for these saws, better to find a local or online supplies that will make the bi-metal blades to order.
