  1. So I did some more testing, while forging down and old cold or hot cut into a hammer eye punch; when the hammer was playing nice, it was doing a good job off knocking down the stock.  I somewhere misplaced my tripod, so no video yet.  Still have some issues with the control mechanism to work out, as the "button" on the rod that goes up and down with the ram to act on the solenoid switches keeps messing up the upper switch.

  2. So earlier there was a discussion about the orientation of my leaf spring helve; after some tests, I did see the need to place a strap around the leaves to keep them together on the side closest to the ram. Thanks to Buzzkill and JLP Svcs....the strap lets more of the input to be output, thus a harder hit and less flex. This necessitated some changes in the arrangement of the switches and actuation arm thingy; will do more testing today and maybe video.

  3. I have a 7 foot SS hex shaft about 2.5 inches across that looks to have been used as a drive shaft for some kind of machinery, probably from the tuna packing plant here, that broke and was found in the local scrap yard. It is non magnetic and i have not tested it yet for hardenability, but will cut off a piece and see how it works as a dive knife. Are there any field tests beyond the magnet and hardenabilty to try to ID SS series?

  4. Don't forget the excavator hammer bits....they are designed for impact. I hauled mine from Kauai, where I used it for a bladesmithing anvil mounted in the ground, to American Samoa, where it became the anvil for the power hammer I recently completed. They come in various sizes; there were 4 of them in the scrap yard, and I took the 2 I could move by hand.

  5. Arftist, no question that mechanical hammers can hit hard...I was speaking more generally about home made hammers...I answered a question from another poster who asked why i did what i did.....basically because it was what i could do. Others can do other things. Lots of ways to skin a cat. Not sure what geometry problem you think i had; i worked that out in the design stage by observation. I am happy with how the hammer hits; i will post another video when i forge with it. BTW, James Helms' "Gunnhilda" home made mechanical hammer hits pretty impressively, but the die arrangement takes up more space than i would prefer.
