I use slightly different products than Timbo, but bascially do the same task.

I didn't see the 'repair' done for the cabinet / floor.  What are your plans for that area?  If the whole cabinet is unstable you don't want it moving as the filler of the top of the nails will crack and cause you more grief! (and I hope it wasn't a nasty surprise seeing the repair!)..

If you get stuck with the ball lane apron repair, let me know I've got access to a TIG and should be able to make it right.
