I take each screw out from under the playfield I put it in the same place on the 'new' playfield.
Yep, i would have done that anyway (it's how i usually transfer other equipment i deal with), it just saves having to create 48 little groups of screws all over the table (which always seem to get bumped and mixed together), when i can put them into the destination PF and be sure i have the correct screws for mounting each item back correctly too.
Yeh, it's not hard or impossible, there's just a lot of it hehehehe.
Thanx guys.
Marty.
