slate liner
I have resized slates to fit from a larger to smaller table, I used sold MDF under each section of slate just not around edges, -I used the board mostly for a height helper and the full board quites the ball noise'
I did use the longer slate screws but the rails bolts/studs are the same shorter original ones because I drilled out the rail bolt holes lager in the wood so the star dome washer contacts the bottom of the slate not the wood'. Mostly all quality tables have the same thing where the rail bolts holes are on the bottom side of slate'
_I used a paint roller on the 3M scotch weld neoprene 10 light yellow contact adhesive to attach MDF to bottom of slate..
-have a good day'
