My father is a casual woodworker, and rarely deals with something as precise as fine joinery, and has been using his father's old table saw for his whole life. I believe it is a 1960s craftsmen with a cast-iron top.
Though I think it is fair quality, age has taken its toll and the saw can be a pain to use. Part of the track for the fence has sunk and it does not operate smoothly, the bevel has been broken as long as I can remember, and truthfully it may just die entirely.
The family is thinking about replacing it however, for the amount of use it would get, I think a cabinet or hybrid saw would be out of the budget.
My questions are, would a new jobsite saw be a big step down from the current machine in quality? Would building a nice bench to house it and expand the top help rectify that? Or are we better off working with the old saw?
