  1. Oh awesome! I like the idea of shortening the axles. Would make for a much more compact hammer. Yeah, I'm aware that the spring mechanism is far more complicated than it has to be. And will be updating it eventually with a heavier hammer and lighter rotating mass. Along with a lot more panels covering the moving parts. For starters I wanted the spring tension to be easily variable though and free is good to start with too. I wonder why they had so much rotating mass in the flywheel on the front of the hammer there. The next project is a pneumatic hammer and forging press. The log splitter I recently picked up seems to work quite well, but I might substitute in a larger cylinder as it perhaps moves too quickly and could do with a little more force.
  2. Hi everyone, I saw this idea in a rough sketch on pinterest about 5 years ago, and only recently managed to get around to trying it out. Hopefully this will start a new type of cheap power hammer for us novices I like to call a "Diff hammer". Basically, you power the tail shaft on an open rear vehicle diff, then brake the opposing wheel to send force to the hammer drive. Made exclusively from free parts, excuse the welding of a few novices. This is powered by a 3hp DC treadmill motor, using the treadmill front drive roller as the drive wheel for a V belt, but a flat belt would also work. The plans were to link the two brake levers together, so the hammer was actively braked as soon as you lift your foot, but I haven’t found this necessary. The hammer spring is offset by an opposing counterbalance on the wheel to prevent additional vibrations and noise. I used an opposing spring mechanism as I only had access to trampoline springs for free at the time, and it made the spring rate highly adjustable It is a very quiet unit to run, and bearings are all available at local auto parts stores should they need replacing. The anvil is a big 130kg round of cro-molly I got for scrap prices, with a bit of rail line welded to the top sitting on a 100mm thick 300mm round I got for free from a local laser cutting place Video of it working hopefully to come on Thursday. any advice would be thankfuly recieved.

  3. Thanks mate! the DF in the forge videos were some of the ones that have inspired me to have a go myself at them. His look great! hopefully mine come out as something similar.
  4. Thanks mate! I'm using a 75kg anvil I picked up for $200 at the moment, and have a proper wooden block to go under it now (45kg in the original was a typo). A solid base makes a big difference.
  5. Hi all, I just thought I'd introduce myself and see if there was anyone else nearby. Names Matthew, I'm 28 and just getting my own forge set up here in Bathurst, NSW, Australia. I'm a contaminated land, environmental and marine scientist who is taking a break from the city rat race to set up an off-grid workshop here. I'm looking to make groundwater sampling equipment for the mining industry in the workshop and research and patent a few remediation methods while I'm at it. Hopefully I'll have time and space to also do a bit of forge work, and build my John Welsford "Navigator" a 5m sailing boat. I have a 200A AC/DC TIG welder, table saw, pedestal drill, drop saw, cut-off saw I managed to source myself a 45kg anvil for $200, and a forge for $110. as well as an antique set of leather bellows for $120. The bellows are too far gone and a little on the small side for what I'm looking for for the forge, so I plan to build my own great bellows. I have sourced and stripped a free fake leather couch of its PU leather and will be using that for my bellow material for the time being. I'm planning to make my bellows slightly lighter than the other plans I have found so far, by using more cross-bracing and thinner planks. I can get hardwood planks free from used Australian pallets. here's a video of the forge before I got my anvil, linked to youtube, so it won't take up server bandwidth.
