  1. I guess it kinda depends on how you look at your equipment Bob.
  2. Thats a nice touch. I like how simple it is to adjust the linkage.
  3. 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.
  4. 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.
  5. 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)
  6. 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.
  7. 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 ?
  8. 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.
  9. 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 !
  10. 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
  11. 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
  12. 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.
