Ditto on the nails. They will nick/ruin the ball set.I don’t have a great picture of my old 8’ and it may not be possible for your table but I replaced my pockets and this is what they look like. As well your cloth is lifting at the pocket. I would try to find a mechanic to fix your table. Nails should be nowhere near a pocket.View attachment 887368
as far as I know it was designed this way, all the pockets have the wood inserts. It's a turn of the century Oliver Briggs table, the slate is from J. Magann and CoOH! That's why it looked like the cloth was lifting due to the angle of the insert. Man that is very different. Is that the way the table was designed? Or was it an alteration due to issues with the slate? And I see why you can't do the cuff treatment.
