I wanted to make a round press plate, for a 12 ton press, how thick
should it be. Thanks

I would say 3/4", but it depends on what is has to bridge.

My press is about 6.5" between beams, and I usually start with two,
10"x3"x1.25" cross bars.

About 6 inches.

OK, good to hear, at least I have that sort of size plates (3/4 a bit
more), I do not need thicker size. Thanks

Most of the plates supplied with the import 12 ton presses are 1".
Probably overkill for 6" bridging unless you have two plates to press
bearings.

I would suggest a double plate. If you lay my bars together one way, they
leave a 1.5" round hole in the middle. If you switch them, they leave a 3"
hole in the middle.

Btw, my press is a 12 ton also.

I think there's some ambiguity in the original post. I believe Iggy is
talking about the rotating plate for an arbor press. The disc on my
Greenerd #3-1/2 is about 11" dia x 1-3/4" thick.

Yes, that's what I am talking about.

I have a 3/4" thick plate that I can use for most projects, and two
1.5" bars, it should probably suffice. I would need to cut this 3/4"
plate in several pieces and need to make some openings in this 3/4
plate.

I used beam boy to run some numbers, for a 1 inch thick, 12 inch wide
plate that spans the 6 inch gap, using 24000 lb load, the max bending
stress is 18ksi, typical hot roll should be good for 36ksi, and the
deflection is just under 10 thou inch.
For a .75 inch plate, max bending stress is 32ksi, and deflection of
0.022 inch.

A 12 ton arbor press must be an absolute monster. Where are the
pictures Iggy? You are the best one in the group for posting pictures
you have to have posted this.

Same here. I thought most arbor presses were in the 3 to 4 ton range.

It is an absolute monster. Weighs 600 lbs or more.

I put a little bit of a comment on that webpage to describe gthis
press better, and mention what I have done to it.

Ive got (2) 15 tonners. They are only about 24" tall....

The handles...now they are pretty long.....long enough that they damned
near reach the ground below the bench.....

Iggy,
3/4 with a 6" span is good for about 3-4 tons without deflection. I use 2" for my 60 ton. I would use at least 1", perhaps 1.125.
Drill a 2 in hole in the middle. Very useful.
