3-4 apply plate warping Hello gentlemen, I have a few questions regarding the 3–4 apply plate. Number one what causes the warpage or unevenness of the plate shown when trying to flat sand? Number two how crucial is it to correct this warpage on stock rebuilds also on performance builds? Number three what technique do you guys use to flatten the apply plates? I apologize if this subject has already been covered. Thanks again for your time.

It is critical that plate be flat, Stress and heat cause the high points and warppage. I use my lathe to accomplish this with both plates, But if thats not an option they are pretty cheap new on Amazon and are mostly straight, I do still even run those on the lathe as while close they are generally not perfect even new. But I do see this as a crucial thing raised areas can cause hot spots on pack on apply and more warpage of steels and subsequent burns on frictions. Its also important to check frictions and steels are flat on ocassion i will get one of those that is warped bent in a pack.
Also sonnax sells some super duty versions https://www.jegs.com/i/Sonnax/852/74...BoCLoMQAvD_BwE
Now if you are into wood working you can use one of these, Careful make sure you have a solid hold with vise grips / I did this before lathe . just remove the front guard. It also may be possible to slow it down with a ceiling fan speed reostat. Planned to try it but purhcased lathe before I got arround to it.

2) I believe it is crucial to performance units to flat sand the plate over a piece of 1/2" of plate glass or use a builders bench stone.
3) I use a bench stone on the 120 grit side to cut it quicker and then 180 to smooth it.
here is a link to a builders stone on eBay

"Now if you are into wood working you can use one of these,"
I apologize, I did not get the reference here. I am not particularly into wood working but if it less expensive than a lathe I would look into it.
") I use a bench stone on the 120 grit side to cut it quicker and then 180 to smooth it."
The stone listed here is 4" in diameter. Is that size correct? How often do they wear out? I would assume they are more resilient than sand paper which I have run through very quickly.
Thank you both for your help and suggestions.

For a long time I used a 2' square piece of 1/2" plate class, I used a 20" PSA disc glued to each side. 1 was 120 grit, the other was 180 grit. The paper wore out quickly and were $20 each. The stone was more cost effective
