  1. Thanks Glenn, This should have been the tone for all the replies. I'm all for CONSTRUCTIVE criticism, just not the patronizing comments of some who replied. And I'd add one caveat - take the GOOD advice of others and ignore the rest. They'll always be someone that just can't help giving negative comments but don't let them bother you.
  2. JMANN, Every time I read this thread I get more annoyed. Many of the responses by the 'experts' are not only condesending in tone (and in some cases arrogant as well) but inaccurate as well. A 20 Ton 'Mini-Press' made with a Harbor Freight Air-Over-Hydraulic Jack is not an 'explosive danger'. Having made several of these presses and tested one to destruction, the only danger is getting you finger pinched off if you put it between the dies while simultaneously operating it. I'm not a 'professional' or 'certified' welder although I have taken several Tech College classes on welding. My w
  3. I've drilled and tapped black iron to recieve a .030 MIG nozzle for my venturi forges. Worked find with a little pipe dope or teflon pape. I once made the mistake of trying to use a .030 MIG nozzle that had metric threads - which naturally leaked. A little J-B Weld solved the problem, didn't need to braze or solder. Here's a photo of the MIG tips on a 3/8" black iron (steel) plug
  4. Should have read 'edge thinner than spine' my bad -
  5. Lendlas, Assuming burners of the same size, two will heat faster (much faster) than 1 and sometimes use less fuel. I've found that in my 7" diameter, 12" long forge, it loses heat faster with just one burner and requires more fuel to compensate. When I switched to two burners the forge heated up faster and retained the heat easier. While the faster heat was expected, the heat retention I can only attribute to the fact that one burner is trying to heat the entire forge and losing heat at both ends. Two burners each heating half the forge operate at a lower fuel flow and it seems to be l
  6. To answer your question - yes that looks like a neutral flame - the best kind for general forge work. I've found that tuning forge burners, regardless if they are venturi forges or blown forges, is just a matter of adjusting the amount of air relative to the fuel. OK that sounds like a no-brainer but whenever you adjust the fuel pressure you have to compensate with the air flow. There are a lot of examples on how to do this if you look under oxy/acetelyene welding - even a number of YouTube videos. I usually start by setting the fuel flow/pressure at what I expect to use (forging or we
  7. I also get mine at a place that sells wire rope and services the shipping industry around Seattle, WA. They always have scrap pieces and I gotten so really good stuff for free. The most I've had to pay us maybe $.50/lb (scrap value). Ususally I don't even have to think about a spark test - they have the specs available! I would think there would be a number of similar places in the NE.
  8. The most valuable material you can salvage, by far, is the track itself! The 'HC' spikes might make decorative knives (I've made more than a few) they won't harden much, if at all, even with the best heat treatment. They are designed with low carbon content so they'll bend before breaking. The track on the other had makes excellant anvils, most hobby blacksmith and bladesmiths I know have at least one (I have two and would like more).
  9. I just read this thread and I have to disagree about 5160 containing nickel. I use 5160 a fair amount and to my knowldege is lacks any nickel at all. It is sometimes difficult to forge weld but I believe that's the chromium. On the other hand it welds easily with a MIG welder - and makes excellent anvil tools like cut-off hardys. It also makes a good blade on its owm Admiralty Steel and others show 5160 as: Carbon 0.56 - 0.64 Chromium 0.7 - 0.9 Manganese 0.75 - 1 Phosphoru
  10. Eric, I just welded a couple of pieces 3/8" square steel tubing'guides to the bottom anvil support and the fabricated a sliding tool rest using 1/4" square tubing. The 1/4" slides through the 3/8" 'guides' easily but snugly. Since it is attach to the sliding part of the press it is alway at a usable position.
  11. I started on coal/coke/charcoal forges so moving the piece comes naturally . Oldtime blacksmiths were constantly moving the metal to heat the right spot just the right amount - funny how when some things change others stay the same.
  12. Even when taking care I seem to inflict damage to the refractory cement coating I use to seal and protect the ceramic wool. For periodic maintenance and repairing cracks or voids I use an inexpensive refractory cement like Meeco Mfg. Co., Inc. 611 Gallon Refractory Cement (3000 degrees) or Rutland 211 Dry Mix Refractory Cement 10 Pound (2500 degrees) and then coat the surface with ITC100. This has been the best and least expensive solution I've tried and works well. The ITC100 protects the cement from excessive heat and reflects the heat back into the interior of the forge - heats faster and
  13. One of the keys for me is to make sure the entire interior of forge is hot before putting anything in it. Even with good burner design/placement creating a swirling flame, metal is going to heat unevenly. Blades are a prime example - even a forge with perfect heat distribution will heat the thin edge faster than the spine and the tip faster than the base. You just need to move the piece around to get even heat distribution - you can't expect the forge to compensate for the varying thichness of the metal. My forges have removeable rear covers, one with a slot for passing thin stock such as
  14. Maybe - I used to frequent this forum before my old 'puter died. I may have met you at the Mt Vernon Hammer-in but I was just passing through and couldn't stay. Personally I just like to make my own tools whenever possible - forges (propane and coal/coke), air-over-hydraulic mini-presses, hardies, etc. Besides the 'puter problems I've been rebuilding by shop - two bits of advice - good insurance and lots of digital photos. Here's a photo of another 'tool' I made:
  15. One more photo - after only two minutes plenty of heat!
