Quoted from russdx:

will you need to remove the braiding for this repair?

Quoted from dr_nybble:

No it's easy enough to take everything out of an EM. Might have to pull a few staples.
See Vid's Guide for removing side rails, that is probably the toughest part.

Quoted from baldtwit:

easier if you have the equipment to make accurate cuts and compound angle joints.
since modern glues are a lot better, usually people keep the joinery simple and it's strong enough, so they don't make the cabinet the same way and only the dimensions matter.
if your current cabinet is too far gone to repair, I'd consider trying to find another cabinet from a parts machine that's in better shape and start with that. Making a cabinet from plywood sheets is only economical if the labor is free and you already have the needed equipment.
typically the only cabinet that can't be repaired is rot / termite damage or massive delamination of the plywood layers - or swollen/moldy particle board if the cabinet used that.

Quoted from dr_nybble:

Again there is a Vid's Guide for it: https://pinside.com/pinball/forum/topic/cabinet-restoration-vids-guide

Quoted from jrpinball:

I don't know why it always has to be a mystery as to what the actual game is. Always leaves me in suspense.

Quoted from Mikala:

What game? What manufacturer?
I can (and so can you) completely gut and empty out a Williams or Bally EM in under 15 minutes, and that includes removing the back bars, flippers mech’s & coin door. Gottlieb’s are a big “PITA”, but it can be done.
