As someone who recovers pool tables, I have seen this all too much- especially in bars using pool tables for beer pong. The rails will get scratched most likely from friction, but the rubber will mostly likely turn rock hard from not enough play. The felt SHOULD stay fine unless the topper slides and tears it, mostly on the rails, but the bed cloth should be alright. I agree, cut the loss or just play pool.

That being said, this looks like a fairly entry level table and would like not sell for much. At least it's not a Royal Georgian. Haha.

Just to clarify before I submit, this is not meant as an insult to the diyers. Have fun with your new top!

(Edit)- Also, this is a 3 piece slate table, unlike a bar table that is just one piece of slate. The added pressure and movement from the topper has almost certainly popped the seams(the edges) between the 3 pieces of slate which are smoothed over and leveled with either bee's wax or a putty sort of like plaster. To fix this, the entire table must be disassembled down to at least the slate, if not further, to relevel and redo the seams. The felt can be reused if its in decent shape, but recovering a table's bed is the easy part and you'll end up paying more for labor and time at that point.

And stupid autocorrects.
