Gold Crown 4 Pocket Rebuild

I recently got a hold on a GC4 with standard specs and I would like to extend the subrail, change the pocket angles and maybe change from SuperSpeed to another cushions. Since I live in Europe and don't have any good table mechanics around I have to do it by myself.

I would like to have 4 1/4 pockets and I dont want them to rattle so I think I will go with 141° angles. I haven't decided on down angles yet, the shelf are standard for brunswick (pretty shallow) so if a max out with 15° maybe this will make the pockets to forgiving?

I don't want to cut in the original rails so
my idea is to glue on the subrail extensions and the cut them to my chosen specs. What material would be best to use? Can I use plywood or is there a risk of the plywood splitting if it is cut diagonal? Can I use solid wood instead?

I'm planning to build four jigs in order to cut everything in an miter saw.

And we are off! This is why I am choosing to do it myself.

I got the cloth off and checked all the rail bolts found that I have two nuts in the rail that I have to change before I get the new rails on. I have not decided on rails yet but I think I will go with Superspeeds. Will clean everything up and start drawing on the final specs for the pocket.

Right know I'm thinking 4 1/4, 141 and 12. And 4 3/4 for the sides, don't know miters and down angle yet..

I'd go 4 7/8" on the sides.
 
Poplar is best for extending rail.

Also now would be a great time to replace the rectangular nut that holds rails down w/ the threaded insert that diamond uses, they are inexpensive and can be tightened/ secured better.... new inserts & bolts.

Not necessarily. The floating nut plate works well so long as some hack hasn't cross threaded the insert. One should NEVER use power tools on rail bolts.

I start them by hand and make sure they're threading properly, but then hit them with a drill that has a clutch on it. I set the clutch to stop at around 8-10 ft.-lbs, then use a torque wrench.
