laughing, thanks wish I got a commission.

I got one on sale about $60 out the door using the 20% off coupon on top of the sale price. You just have to look for the right special to run. HF puts them on sale like that a couple of times a year as a weekly special. That the cheapest you will find it.

 

Got it two weeks ago.

Hi guys .. my home depot type of store finally got an air/over hydraulig bottlejack. its the FIRST time ive seen this in a reasonable priced store here in my country ( norway ) .. however.. its a 12 ton thingy ...

would it do ANY kind of work in regards to a DYI hydraulic press ? .. or would it be a waste of time and money ?

I picked up my steel for the press, foot switch arrived yesterday, and bimba cylinder for release valve on the way. With God's help, my friend Fred, and some luck will start on the project when I get back from my Handles & Guards class.

 

To make life a little easier I paid to have the steel cut to size. The cost for that was way less than what my time is worth and all pieces are cut correctly.

So, after collecting parts necessary, I finally got this done... I used the I beam from a 4x4 jack, a few pieces of scrap, and a 20 hydraulic/air Jack from hf... A good friend helped me weld it up... I used angle iron for die holders, so I can build dies as needed... I've got two stacks of 1084/15N20 welded up and handled to attempt my first run at damascus...

I read this thread back in '08 and decided I had to have one of these. I'm finally setting up my permanent shop so I got my HF jack on the way! Can't wait to put this thing together!

You will love it once it's built!

I finished my medium-sized forge press this weekend, and it works amazingly well. It is the same basic design as all the presses in this thread, but it was made with 3" square tubing. I also reinforced the inside and outside of the cross beams with additional steel. This thing is heavy and solid, and it crushes steel really well. I can't begin to say how happy I am with it.

As to the questions on the air compressor ... I use a very
old 3 hp 120 psi max compressor. The pressure never seems to get up to 120, but
stays around 100. It works fine, but a larger compressor would be much better.
HF 20 ton recommends no more than 120 psi. Sorry for the long delay in
answering questions, I need to check to see if I am getting email updates. Your
ingenuity in the various press designs are amazing.

Hello, been re-reading this post from quite some time.

 

So i have the compressor and the air jack :D

 

now i have a basic idea of what i plan to do but before buying the steel for the construction i would just ask few questions :)

 

I saw different designs and was thinking of using a 1 " thick or 1" 1/2" plate for the base, so basically around 30 mm, would be that enough to withstand 20 tons of pressure?

in case i tough of adding some reinforcements under it lengthwise so it doesn't bend :)

 

not in a hurry so answer with ease :)

The 1.5" would be better in my opinion. More in this case would not hurt. I used .25x2x2" tube and .375 plates and above/below it.

I just made a new set of dies for mine. Drawing dies out of 1045 mounted on A36 steel plates.

Hey guys, I know this thread is old but I'm starting this project in a week or so, pretty much following Ken's design to the letter. I saw someone mention a Millermatic 210 mig welder used to weld the frame together. is that sufficient to weld 1/4 inch 2x2 tubing? I have a Lincoln mig welder, it's worked great for welding up a belt sander frame but I'm worried about the strength required for a press.

I used 1/4" wall 2" x 2" for the uprights. I would think that you would want to go with 1/4" wall. 20 ton is a lot of pressure. 2" x 2" will also give you a little more surface area (hammer & anvil). I have the bulk of mine welded up now, and happy that I went with the 2" x 2", also just looks good too.

 

Just my 2 cents though....
