Here's a little secret for you, seeing's how you THINK you know so much about..."Old Brunswick's" and Artemis cushions

The cushions on the "old" Brunswick's are 1 1/8" wide...Artemis K55 cushions are 1 1/4" wide...and in order to play right...require a different down angle on the sub-rails to get the nose height correct...BUT...the rails from the factory are not consistent in thickness at the top of the sub-rails...which is where the cushions line up at to set the nose height....and if the rails have different thickness's...then the nose height will also be different from rail to rail. Now, lets take a set of rails Ernesto worked on installing K66 cushions, belt sanding down the tops of the sub-rails to fit the K66 cushions...you'll NEVER get K55 cushions to fit right on ANY of the rails...until you first replace the wood at the top of the sub-rails in order to restore the straight edge on the top of the sub-rails needed to align the cushions....
hmmmmm....quite the dilemma you have going on there making that kind of a statement:grin: Don't even think you can correct the problem with the rails on a table saw....because it's no where near accurate....because how do you cut a bowed rail....straight?
You should really stick to what you DO know something about:grin:...you'd be better off

And since we're on this subject...4" to 4 1/4" pockets...what miter and down angles would they be at to make them play at their best? How thick would the facings be...as they have an effect on the play of the pockets as well?
