Arbor Press

I bought the press for $140 included a very heavy stand.
It's in decent shape I think. I have it apart now just cleaning it up.
Question, What are the holes on the ends of the ram for, dies or??
Oh and it did not come with the bolster plate. I thought there would be a hole for a pin for it to rotate but there is not.

Is 4140 an acceptable material to make a bolster plate?
There's a 7" x 1.375" I'm looking at.
 
I made one for my 2 ton press out of A36. Works fine for my use.

I was in Fusion tonight and grabbed this while in there. This is what I made for mine, based on the material I had on hand and the size of my press. Don't know if it's of any value to you, but thought I'd share in case it might be. I made it out of 1" thick A36 plate. Bolster Plate.jpg

Concur with A36. If I needed to make a replacement it would be A36.
 
Like some others I have a 3 ton (Grennerd deep throat) and a 20 ton hydraulic. The Grennerd gets used for broaching and fitting small bearings. In my opinion anything smaller than a 3 ton would see limited use. Even with a 3 ton capacity you have to apply considerable force to seat some bearings. The hydraulic gets used for removing large and fitting larger bearings
 
Just curious. Why an arbor press over a hydraulic H frame type press?
