    Could anyone make an educated guess as to how much this machine weights? Thanks. John

    You would have to know a little more - like "flywheel" diameter. (its a FLYWHEEL PRESS) 1901 Manning, Maxwell & Moore Machine Tool Catalog lists similar of them from 550 to 11,000 lbs

    If a 24" "flywheel" then 900 - plus the motor, etc - like die bases installed. Jumps right on up from there

    May have a number "size" cast in the main frame. The above would be a #1. The 11 k job is a # 5 1/2

    The OPs photos do not show the press described in Post #4

    This reference puts it at around one ton. That seems like a decent estimate, but it could be somewhat heavier. 21 Ton Bliss 19C OBI Punch Press, Model: 19C, Year: N/A, Serial: N/A, Capacity: 21 Tons, Stroke:

    We do what we can, John. . I doubt the OP's is hugely heavier (or tinyly lighter? We don't say that, do we?).

    But if you WANT heavier, then check out the crank gear on the second page of this link: https://www.kempler.com/sites/defaul...og%20750_0.pdf

    Thanks for the input. My guess is 2000 lbs. plus.
    A fellow plans to look at it Saturday. John

    Mot sure I’d call that a back geared press... I’d call it a gear driven flywheel press. Backgear presses have a motor that rotates a shaft with a flywheel on one end and a gear on the other which rotates another shaft with a second flywheel at a lower rpm. Presses are rated for tonnage near the bottom of the stroke(1/16”) whereas a backgeared rating will be approx. 1/4” of the bottom. Great for forming operations.

    I found that it is a "Stiles" power punching press No.3 Not rated in tonnage. Probably pre teens.
    Weight is approx. 3200 #
    Adjustable stroke 1/4 to 1 inch
    1/2" stroke
    725 # flywheel
    43" x 38" floor space
    No motor specs.

    My last post should read power punch press and 1" stroke. John
