  1. I think I will, and I’ll definitely keep y’all posted.
  2. Okay, I see what you mean about the fittings. Thanks. I'm frankly not sure about the inadvisability of using the propane tank for a reservoir. I hear what you're saying about waxy mercaptan buildup, but as I recall, Mike's complaints were all about that buildup forming in burners, where you're working with a gaseous environment, not a liquid one. If there is a mercaptan buildup on the inside of the tank, and given that (as you say) it's really hard to remove, then is there any reason to believe that it would come off the tank into the hydraulic fluid in sufficient quantities to cause any problems? If it dissolves in hydraulic fluid, why don't we clean burners by soaking them in hydraulic fluid? And even if it does dissolve in the fluid, that's only a couple of cubic inches (at most) dissolved in five gallons; is that really going to be a problem? (On a side note, if Walt Whitman had been a propane chemist, would he have written “O Captan! Mercaptan!”?)
  3. Here’s the space available, with the pump and the tank removed. The pump attaches to the bracket on the lower right, and I was planning to put the filter up next to the pump in the upper left corner. That leaves all the space in between for the reservoir. And just for giggles, here’s a propane tank stood up the approximate position where it (or another tank) could go:
  4. I’m not sure what you mean by this. Could you elaborate?
  5. Okay, I have a crazy question. You all see the reservoir in the picture above. If I were to slice off the end with the outlet (to the right in the photo), weld up a tank with a three-gallon capacity (say, a 9" cube) out of heavy sheet*, weld the outlet on the bottom and the rest of the existing reservoir on the top, that would give me a large enough reservoir without having to sink in a lot of cash. Since it's a low-pressure environment, I'd just have to make sure my welds were watertight. Does this sound reasonable, or am I utterly insane? * or even, to be really nuts, an old propane tank?
  6. Yes, here it is with a gallon milk jug. Definitely will. In the mean time, I've wrapped some copper wire around the pipe that will go from the pump to the valve, to help radiate some of the heat: And I'm probably going to add some aluminum fins to the reservoir as well.
  7. Hi, Bill, and welcome to the party. Looks like you're at a good starting point, so take some time to read over the forum for things that catch your eye (especially the READ THIS FIRST tab at the top of every page). There are some good threads for refurbishing forges, so that's probably a good place to start.
  8. I'm a bit late to this party, but I can vouch from experience that the visible seams on the face plate are not an issue. My own Mousehole (aka The Undisputed King of Anvils) has visible weld lines, and they have never given me the least bit of trouble.
  9. That's the one you got from HGR, right? Glad to see it kitted out so well.
  10. I've ordered the filter, but will be holding off on changing the reservoir for the moment. As Frosty noted in our offline conversation, I'm not going to be using this as a full-time production machine, so heat buildup probably is not going to be an issue. We shall see.
  11. So, would that be the flow rate at the first stage or the second? That is, an 11-gallon tank, or a 3?
  12. Four options: Keep as-is for historic and aesthetic value. Restore the steel face for regular use. Cut off the remaining steel face and use as a soft hammer for hitting punches and other top tools. Cut apart and use the wrought iron as stock for other projects. Which one is best is entirely up to you.
  13. Okay, I've been doing a little quick online research for filters, and there's something I don't understand. I get the gpm ratings (and why it's better to have a lot more capacity than you really need) and I understand the size of particle the filter will capture, but it seems like most of the filters out there (at least at first glance) have much lower operating pressures (~150-200 psi) than The Pressciousss cranks out. Do I need to look further to find something with a 3000 psi rating, or does the return side of the system really have that much lower pressure?
  14. Okay, figured out a way to make it happen. Also ran some more fluid through the system while it was set up in reverse. Filtered the used fluid through some paper towels: Which produced a fair amount of crud: I’ve removed the pump and will install the replacement when that arrives. Fingers crossed.
  15. I’m not sure I can do that, since the inlet to the valve (from the pump) is a solid tube rather than a flexible hose. Sounds like it might be a good idea to filter all the fluid (when I drain the system to switch out the pump), just to be on the safe side.
  16. The speed is the same on both open and close, so I don't know if that would be the problem.
  17. As my brother says, "To each his own, and with it my heartfelt sympathy!" I agree about shortening the pommel as Frosty describes, both for appearance and for balance. You might also think about different ways to shape the butt end, to accentuate the spline grooving.
  18. Good to know. I will check the guides and movement with no load anyway (hey, why not?), but hopefully switching out the pump will fix the problem, if its cause is indeed as Frosty describes.
  19. Haven't checked yet; that's on the docket for after work. Seeing how the ram runs when there's no load at all should be interesting and informative.
  20. I had a dentist once who’d spent a year in the Peace Corps working in a dental clinic in Jamaica, pulling a couple dozen teeth every day. That man had skills.
  21. Addendum: in the "Hydraulic Forging Press" group on Facebook, Nathaniel Brandt of Coal Iron suggests that the pump might be stuck in the second stage because of a tight ram or something binding somewhere. Since it's been pretty humid lately and The Pressciousss hasn't been getting much use, I wonder if some corrosion on the surfaces of the guides might be part of the problem. I think the next step would be to extend the ram all the way and unscrew it from the bottom carriage. If it moves faster when running on its own, then the slide is the problem, and I should be able to fix that with some polishing and appropriate lubrication. Fingers crossed.
  22. The new pump arrived today, and I have installed it in The Pressciousss. I am VERY unhappy, as it does not appear to be working properly at all. By my calculations, it should be traveling at about 2.85”/sec unloaded, but I’m only getting 0.56”/sec. Also, when it reaches the upper and lower limits, the pump bypasses completely, and there appears to be no squeeze at all. Here’s a video: Northern Tool is sending a replacement, and I really, really hope this was just a bad pump. Is there any way that the internal pressure of the system would be exceeding the 650 psi threshold to go from stage 1 to stage 2? Any thoughts?
