Best I could do. It's stuck on with double sided tape. My friend says the cushion chunk is Championship MBS K66 from pooltables.com. Hopefully I'll get the chunk of K55 after this weekend. One of his buddies is getting new K55 cushions this weekend, but he lives near Lansing.

Was able to get a 3 inch chunk of K66. Will have a chunk of K55 after this weekend. (hopefully) Will post results sometime after.

So you can't do the math?

https://assets.testequity.com/te1/Documents/pdf/general_tools/General-Tools_828_DataSheet_0524.pdf Accuracy of .3 degrees. Resolution of .05 degrees. NOT the same. Any good machinist would know that. Do you calibrate it to a known standard before use? Doubtful. Where's the picture of what you...

I used a carpenters square to align it. Good at trigonometry? Figure out the 23.5 degree angular error if the 90 degrees was off 5 degrees. Hint: it's less than 1/3 of a degree.

Nope. Pay attention. 25 years as a CNC machinist/programmer and 10 years as a QC inspector. I made a triangle, as I don't have access today to my toolbox at work full of accurate Starrett and Mitutoyo measuring stuff.Some ruler measurement photos I cut the triangle and measured the 3rd side...

Did you see my previous post about having the rail inspected with a CMM at work? My ruler measurements are very close to what the CMM at work showed.

Here's a picture with a few 6 inch rulers. Rail is bolted to table. Rail height is 1-11/16. And another, (kinda blurry) Distance to point 1.42-1.93=.49 width of taper. From 1st picture 1-11/16-9/16=1-1/8 (1.125) height of taper. .49/1.125=.4355 The inverse tangent of that gives a rail angle of...

Oops. Removing, not trimming.

Also. Thank you!! (for your continued help) I was just going order some K55 cushions today and start extending the rails. I'm glad you recognized the garbage rails. I appreciate all the advice you've given me.

The picture I posted with the 1-3/8 measurement is after trimming the cloth to get the rail to sit flat.

Thanks. I'll do that. Here's a picture of the old cushion remounted with double sided tape to measure, and and one of the manufacturer's label. (no luck researching that)

Not sure if they are original. The mounting surface width of the cushion is 1-3/16 which pretty much matches K66 width. And the cushion to cushion dimensions at 46" x 92" exactly match an 8 ft. oversize table. Any thing I could find on K55 cushions shows their mounting surface width to be much...

Not hell bent. As I believe this cheap table's rails have never been modified, the 1-3/16 mounting width matches K66, and it had K66 cushions on it. From what I could find, K55 rails have a mounting surface width of 1-9/32 to 1-5/16, depending on the internet source. So just wondering why the...

Easier said than done in my neck of the woods. You got a chunk you are willing to send me? I'll prepay postage to you with PayPal.
