- if it looks useful, buy it and find out what it'll do.

...whilst the verbiage is upon me, another example is I saw a brand new Dessoutter pneumatic tapper on ebay. It was mistakenly desribed as a "air drill". I got it for about £20. I'd no need of it at the time but it bought because to me Desoutter are the dogs danglers of air tools. It sat on shelf for a year...... but as I write ..... I'm mid way through a job that involves tapping 400 M6 holes through 8mm steel plate. EVERYTIME I squeeze the trigger I give my self a mental pat on the back for getting it when I did. Really is a swwwwwweeeeet tool.

Grant, sorry about highjacking this thread, it's friction screw presses all the way from now.

You'll have to make your own guess from the example I showed. A piece of 1-1/2" round X 8 flattened to 1/4 X 4 would come out about 16" long. So you must be feeding it in and out, right?

I am not explaining it correctly...
If you laid the round bar down under the dies working the 8" length just like your sample, but 8" in not just 2"..how thin could your press make the bar? No moving the billet, just push after push with the bar in one place.

I'll post a video this week on youtube for what I am looking to do and maybe that will help with the tonnage estimates.

Ric; have you tried high explosives? Simply marvelous things you can do with plastique! (a lot of explosive art is on the campus here since EMRTC is a part of the campus).

OTOH since I was the one who floated a plastic eyeball in the quench tank when Ric was demoing one Quad-State; perhaps I shouldn't encourge him to visit down here and play with "energetic materials"...

I still look closely at my quench thanks for some reason Thomas....hoping they are looking back at me.....I wish the video taken that weekend had worked out..apparently the camera recorded nothing.

I have a Phd electrical engineer down the street and he and I sat down to crunch the numbers on a capacitor discharge coil larger enough to weld 4" cube billets of layered materials...it came out to about the size of three of my shops and rather costly.
There is a stone quarry two miles from me and I have thought about having them do some sheet metal forming for me in the pond they have on site...I may see if they are interested this Summer. I'd like to see 3/4 plate made to look like a Jiffy Pop.

HOWEVER,
I am still trying to see how much push various sized friction presses have and what size I would need for the work I wish to do. So if anyone has a lead on a larger press or knows someone with a good sized unit who is willing to talk to me..I will listen.

You are talking upsetting the bar end to end right Ric?

That's cool about the capacitor.

No..the opposite..lay it down like a hotdog in a bun on a plate and then sit on it.

I 'd pay a dollar to see that!

I'd pay $100 not to!

Say...looks like I can make a quick $200 here.

Grant,
I just completed a new bottom swage for the Nazel 3B and gave her a test. It surely is not as carefree as I imagine a large friction press would be as it bounces a bit with the repeated blows, but it chewed the 8" section down on the 7 1/2" long die in short order.
One heat easy with heat to spare and it is about 1/4 thick more or less with a good spread...think large leaf.
BUT
it is still work of a sort as I did move it a bit to keep it even and under the dies. I'd like it to see how the job could be done under a screw press.

I have no idea if the 100 ton is the ticket or something larger....again..I have nothing to judge it by as my 48 ton hydraulic is slow and the 3B is a different action.
I imagine it is close though.

Whassat, blacksmith math? $1.00 + $100.00 = $200.00?

This may explain my accounting irregularities over the years.

Grant what are the functional differences between the style of press you have and the style without the large rotating disks? It seems that the "weingarten" brand has a different drive mechanism.

Ric

[Nakedanvil - Grant Sarver]

Not familiar with that. Got a picture?

Here is a photo of a 500 ton off a machinery sales site:

I am not all too sure how the drive works...it may be the screw shaft is attached to the motor or the screw shaft IS the motor shaft with the motor being the large cylinder on the top. Maybe.

Ric I really dont follow exactly what it is you want to do... but I think I might have to tool to do it I have a 210 ton Willams White forging press... it only has 12" of stroke but it will make a full 12" stroke and return in just over 10 seconds. One thing is unlike a friction press there is no stored energy being imparted by the "strike" so it wont do the work of a 200 ton friction press, but it will do very controlled forging of large material.

I can see a use for that as well....just did something this afternoon which would have gone faster with that.

What amount of power does it use?
Will it impart full tonnage at 1" and 12"?

Have any photos of what you do with it or maybe a video?
I'd like to see it working.

Its a 15hp system with an exotic oil gear two stage pump.. And yes it will provide full tonnage anyplace in the stroke..

I'll make a short movie of a "major upset" and try and get it posted....
