    Hyd pump

    Right kind of question. My pump is already rated at 16 gpm. what rpm does it need to turn to achieve that? Most sellers rate their pump at gpm not at pump replacement per 1 revolution. Check Northern Tool

    Hyd pump

    At what rpm are hyd pumps rated? 1f your pump is rated at 16 gpm at what rpm is that rated at? 1725 or 3450
  3. Looks like the same cyl I Have 26 inches long almost 5 inches in Dia. with a 3 inch rod. I use a 16 gpm and has a good speed.

    A close call

    Actually a new return line is what I needed. I used a clear reinforced line as everyone said no pressure in the return line. Re[placed the return line and everything works fine. Thank you all for your concern. Take care TJ Smith

    A close call

    Had a close one last Thurs. While forge welding a billet for feather Damascus my press blew a return line. There is not supposed to be any pressure in the return line, but let me tell you a 16 gal pump will spray hyd fluid about 10-15 feet.. The bad thing was the forge was to close and the spray from the leak went right into a 2000 degree plus forge. Instant huge fire. I was operating the press when it happened. Worked fast shutting things down,the press,the forge,grab the fire extinguisher , spray the xxxc out of everything. Have you ever tried to cool down a 2000+ degree forge full of hyd fluid. Finally got the flames out and wheeled the forge outside. No damage to anything except 1 light fixture. Need a new return line hose that will stand some pressure. Mostly a lot of cleaning and probably some new paint. Ought to leave it as a reminder?? Thank God nobody got burned or hurt. Lesson learned. Use pressure lines on the return also,Don't put your forge close to your press. Keep a fire extinguisher close. Take care (Lucky) TJ Smith
  6. Thanks CMS for a decent reply to my question. More time was spent on my having a bad attitude then answering my question. I have been making knives since 1992,have made 3 forges, 3 presses,1 heat treat oven, and several other time saving devices. Thought maybe someone on a thread labeled mills and such might not mind passing on a little info. I am not a blacksmith,but have admired those who are. I will aploigze for bothering those who are to busy to answer general question and will go to one of the other forums. Thank you TJ Smith
  7. Frosty dumbest answers I have ever got. Buy a new mill. DUH not gonna happen. Didn't know I had to sharpen end mills for steel. Could have suggested that. Why am I using a mill. TO make a guard slot. DUH. If you can't give a decent answer xxxx up.Thanks Kozzy and gun doc for some answers that help. I make knives. Thank you TJ Smith Thanks
  8. In Have a small Grizzly mill. It does fine with small end mills in brass but tends to chatter with anything close to 1/4 inch. Anybody got some hint or tweaks to tune it up and stop the chatter? Tj Smith Knifemaker
  9. Yeah looks just like mine. ()range that is0 My freind Dick and i built this . Took about a month. Dick is a excellent welder. We have made several random damascus and are working on some feather now.Love it. TJ Smith

    burnner

    i like to run a reducing flame on my forge to reduce scale. I wouldn't call it soft or quiet. My forge sounds like a jet engine with flames coming out of both the back and front 3-4 inches. After a few minutes of running I can get welding heat with 4 lbs of pressure. I don't think flares or mig tips are going to improve on that. Enjoy the discussion Take care TJ Smith .

    MY forge burner is a simple 8 inch piece of 1.25 black pipe. It is blown with a 65 cf fan. I don't have a nipple or small hole drilled anywhere for propane to enter. My burner is reduced in size from 2 inch to 1.25 inch and gas enters just before reduction. I have a gate valve to adjust air flow. My forge will get to 2350 degrees. Why all the nipples and special flares? Do you really need them. TJ Smith
  12. Here is my way. Get a tight fit. Square the guard to the knife. Use a clamp of some kind to hold it in place. there are several made to do the job. Paint a little flux on the joint, holding the knife with point up so flux doesn't run down the blade. Put the tang with the point up in a vise and put a couple snippets of solder around the joint line. 2 1/8 inch long snippets usually work. I use stay brite solder and flux. Start applying heat from underneath as the flux starts to bubble hit the top with a little heat as the solder melts make sure it is connected to the knife steel and the guard. Take your sharpened wire and run it along the joint, the solder will follow along and cover the joint. Don't just pour on the heat, paint it on as needed like using a brush. should have a heat sink or wet towel about an inch above the guard. Just enough heat to do the job works best . Most problems come from to much heat. I use a propane torch with a auto ligh tip pretty small but works fine Take Care TJ
  13. I used 3x4 x1/4 inch tube for uprights with a bottom mounter cylinder. 4.5 inch used a 16 gpm pump. getting close to 20 tons and does a fine job at that speed. With a 3 hp motor and a 11 gpm pump I don,t think you would be happy with the performance.
  14. I built one. Made 2 harley chain knives on it and several random pattern Damascus knives with it.Just remember you have 20 tons of pressure.Gotta keep the work hot. What the heck you can always use a new jack right? Take Care TJ Smith I did make a 20 ton though just so you know Once your're hooked on damascus you 've had it.
  15. My press moves up. You don't have to lift the work let it ride up on the die and just lightly hold the handle. Mostly a matter of choice. Pressing up requires less head room. Like you don't need a 10 ft ceiling. My anvil is set about eye level or a little lower and is very comfortable to work with. Take care TJ Smith
  16. After looking at maybe a kazillion different set ups I placed my filter on the return line. After all it is a closed system.Maybe between the tank and the pump would be better. I'll rethink that for a bit(2-3 years) before I move IT Check out several working presses and build one. Take Care TJ Smith
  17. I use a canister to enclose the chain, powder, and steel. I think that chain would work, but not by itself there is to much open area between the links.. I use a thin wall square tube. Weld 1 end shut with a piece of scrap over it. Suspend the chain so it hangs straight down into the tube. Then pour 10 84 powder or 1095 powder into the can when full vibrate the can and refill with powder. Weld another scrap to close this end. First put some scrap paper inside to burn out oxygen. Weld on a handle and head for the forge. If this works let me know as I haven't tried it yet. Just a theory. Merry Xmas TJ Smith
  18. Here is a couple I put together. Motorcycle chain,15n20 saw blade steel core, 1084 powder. What do you think? Take Care and Merry Xmas. TJ Smith
  19. Yeah know the feeling. I have been working with a 20 ton air over bottle jack and it does work. I have made several knives with it but it is slow. I am currently building a hydraulic press. It looks like you have all the parts, but don't know what you'll end up with. Clean them up, find out what they'll do, Do the math. Calculate the pressure and speed. That will tell you if they will work or not. There are lots of charts and tables you can axcess to get those numbers. Take care TJ

    Hyd oil

    What does everybody use for hyd oil in their press? Thanks TJ

    press power

    In looking for a motor for a press.I decided to go with a 5 hp 1725 rpm motor. Very hard to find. if I took a 3hp x 3450 rpm motor and used a belt drive to get down to 1725 would that work? What would that do to my HP?Tj Smith
  22. In a hyd circuit for a press what reduces pressure for the return to reservoir? Thank you TJ
