  1. An interesting opportunity presents itself. I may have a line on a secondhand pump that's rated for 16.2 gpm at 1725 rpm. If I use pulleys and a belt to get the output of the current 3 hp, 3250 rpm motor down to ~860 rpm, that would increase the power input to about 12 hp and decrease the volume output to about 8 gpm. That would give me about 2.5 inches/second of ram speed and a little under 16 tons of force, which isn't bad at all. The problem is that the documentation I've been able to find from the original manufacturer talks about the pump running at a much lower pressure than I would be operating at: 200 psi instead of the ~2500 that I would expect to generate with this setup. Would this be as much of a problem as I think it would be? Or would I be able to get away with it somehow? (Worth noting that the pump does appear to have a relief valve.)
  2. What exactly is your question? Whether or not this is doable? If so, the answer is Yes. Just remember that simple carbon steels (mild, medium, and high) are prone to rusting, so you will need to make sure your kit is clean, dry, and re-oiled before you put it away.
  3. Anyone who's met me knows just how much I need professional help....
  4. Got together with IFI member Stash for a truly excellent dinner and some forge time. Stash made a kind of leaf I’d not seen before and showed off his ultra—simple holddown while punching the tab on a bottle opener: And I played around with a waterleaf scroll: Fun was had.
  5. The bottom is held on by screws. Turn upside-down, remove bottom, insert ashes, replace bottom.
  6. It’s wormy spalted curly apple. No specific connection with my dad, but the kind of wood he loved when we used to be woodworkers together.
  7. Yes, this turns the red iron oxide (hematite, Fe2O3) to black iron oxide (magnetite, Fe3O4). Rusting a piece and then boiling it is a classic method of forcing a patina. The Japanese in particular are known for using a preparation of daikon (radish) for the rusting part. Someone I know through Facebook was just talking about doing this with a pressure cooker, which seems like a bit of overkill.
  8. Also, if there are any cracks in the belt, replacing it will be much, much safer than trying to recondition it. Even if you do restore flexibility, those cracks will be a weak spot that you do NOT want letting go mid-forge.
  9. You might consider selling them to a stonecarver and using the proceeds to buy smithing supplies. Or take up stonecarving, of course.
