It is a heavy thing, and comes in two boxes

photo_2021-10-07_20-02-25.jpg

 

The smaller one is the press frame itself. I got the grey paint option

The other box has the tank and power plant, and any dies you ordered. It had the most fascinating packing material: old cardboard boxes that had been run through a shredder.

It took just a bit of excavating :)

That thing is HEAVY. There was no lifting it out, so I had to cut the box (with my nice shiny new 52100 EDC!)

I work in my garage, so this thing must be able to relocate. To do that, I got their heavy duty cart. It is nice.

And here it is in its new home.

UPS failed me, however. They managed to spill the hydraulic fluid during shipment, so instead of my 5 gallon pail of oil, I got a refund. I ordered again, and it should come Saturday - hopefully UPS can manage to not spill it this time. Meanwhile, I have a nice, empty press waiting for it's break-in run.

I really look forward to getting a review on your new equipment.

new machine day is a happy day! Congrats B)

 

Your cart might need beefing up a bit, the hoses will push and pull a bit when they are loaded up!

Thank you all!

 

I certainly will post more, once I have the oil!

 

And that is the cart that Coal Iron sells for this press so hopefully it is sufficient, but I have angle-iron aplenty if it ends up needing more bracing! We'll see.

Yesterday morning, my replacement cylinder arrived. Following KenH's advice, I bought the Wen 4 x 8 inch cylinder, which takes the press from 9 tons to 14 tons. (The "as shipped" configuration has an undersized cylinder and doesn't actually produce the advertised 12 tons). Replacement was basically trivial (once I realized I needed to move the swivel fittings from the gray one to the black one.

I got some shelving to live on the botton to provide storage for dies and other tools. I'm going to put my hardie tools down there too.

The oil finally arrived at almost 5 pm. I discovered the hard (and messy) way that the machine doesn't quite hold 5 gallons: I spilled probably half a cup all over the tank and the floor.  No only did I not need my extra gallon you see there, but I had to find a home for another good cup of oil.

Breaking in at last! That noise is obnoxious, but gradually fades.

 

That was all for last night. This morning, I got started nice and early and worked on the damascus billets. I need some more practice to avoid the press equivalent of hammer marks. This is more than I could do in three weekends previously, so I'm thrilled.The one with the more visible marks was a bit of a blob before, and now is going to get stacked with the other ones I mentioned in my KITH thread. The narrower one is done - I'm going to use it as it is.

Finally, I tried to draw a narrow but thick bar out sideways with the fullering die. This did not work very well, I'm going to have to make a width drawing die to match the length drawing die (I think I have what I need to do that).

Overall impressions:

 

It comes set up to have the press on the left and the powerplant on the right. I prefer to hold my piece with my right hand and operate the lever with my left. But it was easy to switch around, especially since I was swapping the cylinder anyway.

 

It is a bit annoying that the OEM cylinder is undersized, but the Wen tools one is only $133 and you get free shipping.  Still, for what is otherwise a very well made piece of equipment, it is sad that they still sell it as "12 tons" when it just isn't.

 

The heavy duty cart they sell for this press works just fine, and didn't need any additional bracing.

 

It is pleasantly quiet. There is only a soft whine from the motor and pump, and it is perfectly comfortable without earmuffs. 

 

While they hype the "plug it in to any standard outlet" for the 110v configuration, the official requirement is "a dedicated 20-amp circuit". I have mostly 15s in my garage, and none of them are even remotely dedicated.  I do have two 220v outlets, so I got the 220v version.  The cord is quite long, I didn't end up using the welder-rated 220v extension cable I got.

 

The dies are held in by bolts: changing them when they're hot takes a bit of care. But they're slotted, so you only need to loosen the bolts enough so you can push the die out, so I don't think it's too bad.

 

I need more practice both in running it and in picking which die to use for various things. It runs very smoothly and pretty quickly: it is very easy to push things further than I want.

I couldn't help but get a little something ground far enough to maybe show a pattern... it's FAR from finished, but...

Those are really narrow dies for a press, which doesn't help with the bite marks.  You now need to make a set of stop blocks for it.  These are just pairs of steel blocks of equal thickness, one pair for every final thickness you're after.  They sit on or are clamped to the bottom die on either end, and they make the final pass an even thickness.  

 

Presses are great fun to play with, aren't they?

They are quite narrow - only 1-1/2 inches wide. I haven't had a lot of exposure to hydraulic presses before, so I didn't really know how that compared.  I've made two sets of my own now that I used 3/8 by 2 inch plates for, and KenH said he's used 3 inches wide without trouble so I'll probably be upgrading from the factory dies.

 

I had contemplated putting things between the dies to stop them but wasn't sure how advisable that was. It's very good to know that is "best practice" and something to move ahead with.

 

And yes, GREAT fun. I very much wish I could play hookey from my "real" job this week.

Good honest review, it confirmed a few thoughts I had about the press capacity (I worked it back to 7.75 metric tons from the available data online)

 

It will be worth keeping hold of the small cylinder, as the bigger 8" stroke one has stolen 2" or more of your 'daylight' - which might be a PITA if you want to use the press for punching operations etc!

 

In the UK 'stop blocks' are commonly called 'kiss blocks' - they are usually positioned well off to the side of the die block in use, you really only want to 'kiss it' as it will ramp the press slide over if there is any excess clearance in it, which is bad practice!

 

edit, just re-read what Alan said about using 2 stop blocks, one each side of the workpiece. This would be best practice, but in reality you would end up only putting one side on when 'in the heat' of forging ;)

Thank you!

 

Oh yes, I am absolutely keeping the OEM cylinder: it now lives on the bottom of the cart in the narrow spot leftover because the Container Store shelves didn't quite fill the whole space.  And yes, the larger cylinder did take about two inches of space. For damascus bars and general knife-sized work it doesn't make any difference, but I could see it being annoying for a punch.

I often use only one block, but in the middle of my combo dies, so it's directly under the ram.

So how much clearance do you have with the new cylinder?

Had to go measure it: five inches.  Coal Iron's site said it had 6 inches of space before, so I guess I only lost one rather than two even though the cylinder is longer... the bolts must be aligned slightly differently or something.

 

I hadn't measured the clearance before the swap, so I have to go by what they say it was before the replacement. But it's 5 inches now.

Thanks, Ted!  Unfortunately, that might be a bit small for cans.....

For anything larger than a reasonable stack of flat stuff getting welded, I can see it being too small of a press. (But that's what I wanted it for :) )

 

They have videos of people making hammers and such on it, but the clearance really is a bit short for that and I don't see how the great long punch set they have would work even with the OEM cylinder. The only hammer I made so far got its hole on the drill press, and while I am considering making another, I was intending to do the same thing to it.

 

I was intending to try a canister. I got 1-1/2 inch square tube for it, so I would think that should work just fine with 5 inches of clearance. It'll be a little breadstick of a billet that comes out, but I think that's ok for the smaller things I've been making. (He says hopefully)

The place where presses outshine under-300-lb hammers is in squishing large piles of damascus in one go.  Hammers, especially mechanical hammers, need room to gain power in the stroke.  Presses are fine with squashing anything that fits between the dies.  If you could turn your dies sideways to have it squishing along the long axis that would be ideal for setting the first weld.  The presses I have used are set up to do like 2" wide by 6 or 8 inch long billets up to six inches thick in one squish to set the first weld.  Then you can go to narrower dies to draw out.

Hm.  I have a big piece of O1: 3/4 x 3 x 18 inches

 

I could cut that in half, drill and countersink holes for the bolts, and harden it to just be a pair of thick blocks then I could have a pair of (up to) 9-inch "long" dies. Would 3/4 be thick enough for that, or do you think it would need more bracing somehow?

3/4" would deflect a little, but it'd be okay.  O1 is way overkill, though, plain old mild steel is fine for press dies.

kind of agree (but disagree :P) If they are going to be regularly used, use a bit of 'good stuff' for the dies if you can!

 

You will get deformation, and scale is very abrasive. They will end up looking like a dog chewed them, after a while, if they are soft. 

 

Beauty of a press is you can get away with sub optimal dies for a lot longer than you will with a power hammer though!

I was thinking of that piece of steel because I have it sitting here and I don't have anything else in particular planned for it :) . I saw it at a really good price a while back and grabbed it, figuring that if nothing else I would take slices off like a loaf of bread.

 

Another thought struck me, though: The dies are bolted to the frame on this press, don't I need to be careful that it doesn't make enough of a lever to shear the bolts off? So in the worst case that would 14 tons times half the length of the die (though hopefully I wouldn't be that careless) divided by ... bolt cross section? I don't actually know how to calculate that part.
