I guess it kinda depends on how you look at your equipment Bob.

Thats a nice touch. I like how simple it is to adjust the linkage.

Hey Grant, is that anything like the upsetter you have kicking about ?

I've got an old cement mixer I got off a friend sitting outside my shop under an eve. I just throw the parts in with a bit of gravel, soapy water and whatever and leave it run for a while. Parts come out clean and de burred. Its a pretty nice option if your doing lots of little parts. I ran a plasma table for a while and it worked great for small plasma cut parts too.

I'm not sure I would try to cast brassabronzacopper around a shaft. That high a temp and that different a coefficient of expansion and you might get the shaft stuck. I would think of either casting them solid and drilling them out or with a smaller tapered steel shaft that you could punch out or drill out if it gets stuck. Fe-wood has a point that babbit is a little easier to deal with. That being said if you have a whole bunch of free material sitting around it doesn't take a weekend to make yourself a nice little foundry capable of what your thinking. Spend some time looking around the interwebs, there's a whole world out there of info on backyard casting. I've used a mongo burner I made from: http://www.ronreil.abana.org/design1.shtml I've melted 80# of alum bronze with one burner and a bunch of good firebricks. Propane will melt brass or bronze just fine. If you need crucibles a jewelery supply shop is a good place to start. What your thinking would not be a simple job if you have no equipment but it is definitely possible.

I'm not to sure, but I'm pretty sure, (not sure sure, but sure) that there is a reason. I vaguely recall there being something mentioned about it in the Little Giant videos, about how to make your own adjustable arms. Someone out there should know. (maybe...not sure)

Meep. Meep.

A picture is worth a thousand words, here's my idea. The air cylinder ram goes all the way through the cylinder. The two rams don't touch until you want to bring the hydraulic ram down and then the air cylinder ram just acts as an extension of the hydraulic ram.

I really like this idea, I'm wondering if it would be worth the extra effort though. Opposed to just building a separate hammer and press. You would save in materials me thinks, but there would be a fair bit of work into it. With the larger air cylinder comes the need for more air comes a bigger compressor. Maybe you could just have a smaller press ? Just use a really light oil ?

I'm wondering how well this work when translated into hydraulics with oil in it ? How would you get around the viscous oil slowing down the air ram ? Could you get away with huge ports and check valves ? Its a neat idea for sure.

Thanks Brad, but I need all the measurements, not just the angle, and I'm pretty sure they're different sizes for the different sizes. I sure appreciate the offer though. Thats kind of you. Cheers !

Hi Everybody ! So now that I don't have access to my shop anymore (moved a couple thousand miles away for school) I finally have time to work on it. *grin*. I was wondering if anyone had measurements or drawings for dies for a 50# Canadian giant ? Or if you had drawings for a little giant and knew the difference between the dovetail angles. I've been told there different. I have access to a decent machine shop so the actual machine work isn't a problem. I just don't know what parts of my material to leave and what to cut away. I would just get someone to sneak into my shop and measure my hammer for me but I have it locked up so tight a church mouse couldn't get in there....I hope.T Thanks again for the help. Cheers, Drq

That was awesome.

Thats pretty cool ! I don't know if my girlfriend would understand if I came home with a vice instead of textbooks for school... hmmm

I'm pretty sure its Ti, I'm basing that off the facts that it sparks white, is non magnetic and oxidizes pretty colours. When you start getting into these super alloys I'm way over my head. Also for the application it was used in I don't think it would be anything reallllly expensive. There was about 60 sq ft of it lining a pipe that came out of a osb mill in town. I wish it happened that fast. Its more moving and 1/8th of an inch over weeks as opposed to seconds.

I'm having a rather odd problem I've never run into before. I got a bunch of scrap titanium plate (0.135") from a scrap yard a while ago and finally got around to playing with it. I've forged some bracelets out of it and after acid etching and heat anodizing they come out looking pretty neat. Now here's the problem: they don't stay bracelet shaped. Even though I got them to a nice yellow heat at points while shaping them they very very slowly open up, trying to flatten out again. I've had to put mine in a vice twice now and close it up (in about 5 weeks). I did some looking online and apparently ti plate has "memory" to its original form. Has anybody else had this problem forging ti ? And has anyone come up with a solution for it ? I would have thought that the high heat would kind of set its form again, but I guess not. Thanks for the help. Cheers, Drq

Glad to hear these hammers are going to be working in a shop and not going to scrap. Makes me sad to think of all the good equipment and vehicles that have been melted down. Thanks for saving them.

Crap, sorry running new computer system. Sorry for the multiple posts

I've got my machining ticket, lord knows that doesn't mean I'm much of one though. Anyways .. I would say there would be a fair bit of work involves into making one of these yourself. You would need a fair sized shop to do a decent job on the frame. And a lot of steel, and time Now what if...... (Dangerous words) We all seem to like speed of the hammer, but the short, non easily adjustable stroke neccesitates the multiple hammer stations yes? So what happens if we keep the short stroke and the speed but add adjustability. This would allow us to build the same system with only one station. I'm wondering if something like system Hugh Macdonald uses to overcome basicically the same problem inly a rolling mill might work. It's essentially a foot operated cam leaver that raises the bottom roller into the work piece. Someone might be able to expand on that explanation. So what if one was to uze the same system to raise the anvil into the hammer. It would have to be excessively overbuilt compared to the rolling mill, but I'm wondering if due to such a small stroke it might work. Perhaps have it cam over and lock? Thoughts? Would it hit to hard on the cam? Vibrate your legs off? Am I crazy?

I've heard about it in a couple research articles and such, but have yet to see anyone actually using it. It will be interesting to see if anything actually comes of it.

Peacock, the fellow that I talked to this weekend had a three bottom tractor drawn. I will give him a shout and see what he thinks they are and what soil he's playing in. Perhaps I will see if I can get out with him a few times when he's plowing, I think your right that a guy needs to have a little experience in before he really has any clue what needs to be fixed. Bob S, if I'm the old guy I think we're all doomed. Origami, I actually have one of those disk sharpeners, never used the thing, but it holds my dirt down.
