  1. I know that on Bradley Compact Hammers the stroke is adjustable but how much stroke do mechanical hammers have. I am also thinking because of the spring the hammer travels further than the stroke of the crank.
  2. so what have you been feeding it. I have a 200 pounder I would like to get up to 275
  3. I would do what ever the literature that came with the valve says. if the valve was designed to run dry or have Teflon coated parts oil can gum them up over time shortening their life.
  4. I am sorry to hear about your Grandfather passing but that is tempered by the story of your tinkering with Grandpa. When my Grandfather passed my cousins fought over the expensive stuff like his gold watch that he never wore because it was "too nice". I took his tools and every time I use them I feel a connection with him that always brings joy to me.
  5. hopefully I replied to your PM, if you did not receive it let me know.
  6. even at 100% efficiency it still comes up short but as a general rule of thumb you can figure about 70% efficiency in hydraulics. I have a commercial made 150 ton press designed to press forklift tires it is running at about 50% efficiency. 12" cyl at 5000 psi.
  7. For 300 bucks you could spend another 300 bucks buying a multi-lead acme screw and nut from McMaster Carr and spend a week ends making one very nice $600 press.

    MB you could make it a lot more portable. Use quick connect couplers on the pump lines by the valve and make the bending assy. separable from the pump assy then you could modify a hand pump to power the valve. Normally hand pumps have single acting cyls. attacked so the do not have a return line but if you modify the hand pump so there is a port on the reservoir you can plump the return line of the valve into. but hey it is a great thing for sure and has great drool appeal to those who know.
  9. I have some RR but sadly it is buried under the snow and yesterday we took about 2 more feet so I will not be able to find it till spring. But I do have a couple of forklift fork pieces I would sell you for what I get scrap 13 cents a pound plus shipping or if you get around Milwaukee Wisconsin you could pick it up.
