Project 1 by redbeard : Hydrualic Shop Press

[Trip59]

The HF 12 ton is bolted, the 20 is all welded, I brought my 12 back for a 20 before it was even assembled, dang coupon came out that made the 20 cost like $10 more than I paid for the 12.

Was wondering if you might toss up a pic of the setup you used for bending that 1/4"?

Lemme know if you find someone that has those round tuits in stock, I gotta get about three dozen of them...

You are talking to Redbeard I am sure and not to hi-jack his nice press thread. I have mine with a 20 lbs HF bottle jack in an angle iron tray and locked with a top welded ring. So it will not come out once pressure if applied, but will come out when it's not in use to help move the thing. Basically an angle iron bottom frame like a trailer battery frame box, top in a retaining ring.

I found on round tuits. I bought mine on a long-term payment plan. Funny thing, the 16 year old one does more than the 21 years old and they cost about the same. The 18 year old one does cost less, but does less unless computers or plants are involved

Yup Mike, I was. I was actually interested in the brake portion he used inside the jack, I was wondering if it was just a couple pieces of steel held in place, or if it was built to fit/attach to the press itself. I bought my press to handle some random press things (actually made one out of a piece of angle iron to do some driveshafts, what a pain) but mainly to fit as a press-brake since the brake I have is a single length rather than a box/pan brake.

Trip,

Ahh. Sorry, saw press and not brake and responded. Bending 1/4" I should have caught it. We do (not real wide) 1/2" for fun on ours just for the wow factor. I though you were worried about the jack just sitting in there.

Mine is straight, 3 piece angle. Did not see Red's brake. Wish I had all the whole drilled on mine. They are quite handy with you can adjust them

If you search for posts here on our forum by scooter and chadrock you will see a couple recent press and brake projects as well.

Thanks Mike. I have http://www.harborfreight.com/20-ton-...ess-32879.html and it's pretty darn stable, a bit of a pain to adjust, but plenty of holes in it...

I'd seen some other brakes, just always on the lookout for other designs. You can find them on google, but it's rare you can see them and then ask questions about 'why did this go this way'

Scooter bought that one I think and welded it up just to make it stronger. I almost went that way, but the cheap in me and free metal. Took a couple months but we did it.

If you have cash, there is a swagoffroad.com something like that, they have it all CNC made brake, and you weld it together. It is nice, but some fair size angle iron, piece of plate and you can get by.

Scooter and Chadrock gave all the metal sizes, or close enough Chad could copy Frank's version. I can take pic and measure when he used if you need and PM or email to you.

Sorry I just came back to this thread to look up that handy chart and noticed that I was remiss in responding, I hadn't yet discovered the subscription function when I first posted I guess.

Anyway, I wound up doing a couple different setups for the different sizes I've done so far. The latest one for longer stock looks like this:




I just used a couple pieces of stout angle clamped to the channel with spacers for the bottom, and a piece of T-post with the center nubbin ground off as the top die. It held up well for the 4" bends, but it did bend a bit when I went for 8".
Although I didn't notice any signs of bending, if I was going for anything bigger, I would probably take the precaution of running a piece of allthread through the table to keep the channel from splaying.



This is a recreation of the original setup I used for the shorter brackets, a bit simpler just using the plates with spacers on the sides (not the one in the picture obviously) to fill in the space to the legs. If I remember correctly, I used pipe clamps to hold the legs together just for safety's sake.
