So I seem to have inherited an older Delta table saw. I spoke up for it if no one else wanted it as mine is one of those plastic deluxe models. It is a pretty heavy saw and will need to be rolled in and out of the corner of the shop and of course have lockable wheels. When I look at the basic carts, they have two straight wheels and 2 swivel. I'm thinking that I'd rather have all four swivel and lock. Could that make it less stable? It has a pretty good sized top.
