  1. 8x8x1/4" main column has been standing in place waiting for a decision on drive type....flat belt is Found local usables yard for 600# anvil@.25#. Could do a bit better in Phx, not worth 200 mile round trip. I like to throw a little money at the local folks anyway. Thanks for all comments, suppose I'll get to work now......Dave
  2. No trouble Stormcrow, Easily done and undone. I wrote a really long post outlining my thought process and deleted it. Realizing it was just repeating considerations that came from others many times. Perhaps a summary of my project....for me would be better? If you decide to do a simular project....for you there may not be one idea from my project that does you any good. If there is more better. Tire hammer...not pnumatic utility or self contained...not hydraulic press...maybe later flypress...probably later factory hammer...who knows down the road Spring helve....yes Possible mods: 1) air cylinder- for those jobs that need many placed controllable single strikes. Perhaps a variable length drive link? Some interesting combinations of push and pull between cylinder and spring affecting striker action may be possible? 2) tire drive?- been done and it works. You know all the benefits. 3) flat belt drive/idler clutch- Great idea, really like this one. Motor drives countershaft for drive speed reduction and flywheel energy storage. Countershaft drives crankshaft for second drive reduction with idler pulley belt clutch engagement. I have made and fit some leather drive belts for other equipment. It would be fun to hide the air cylinder and impress friends with my antiquity Hope this makes my thinking more clear (if that's possible!) Dave
  3. How did the cylinder mod workout? Did you find value in the concept?
  4. I did't know thieves would work that hard. If caught I vote 1000hrs community service.....on the hammer:)
  5. Dave from one eccentric to another thanks for the build vote:)
  6. Grant, thanks for the advice it is noted. I posted in case someone had a good idea that worked out for them. Better to find out before sticking things together:) Good thing I don't have an inline 4 hanging around, you had a fun looking idea. Dave
  7. George sounds like we started the same way. Glad it worked out for you. Have fun...Dave
  8. And throwing in a few of yours , I've really enjoyed looking at shop built power hammers the last couple of years. Someone or a group will workout a good concept, prototype, bug it out and those inclined use it that way. Other eccentrics like myself perhaps get as much joy from the design/build as the use of it. The personal variations seem endless. The most practical would be to just save and buy one......no fun in that for me! The concept I'm playing....err working on.... 1) 35# to 50# apallachian guided spring helve 2) using the tire drive clutch idea (been done) 3) Replace the crank drive rod with an air cylinder for lenght adjustment, controllable single stike and some clamping ability. Not quite sure how the air cylinder will act in conjunction with the spring. Seeing a pressure feed to both sides of the piston which can be balanced. Seems endless combinations for action are possible. And if disappointed a drive rod will make a working hammer. Guys like me always have a ton of possible refinements churning in the back of their head....Please feel free to throw yours in or punch holes as much as you like....it's all fun I'm new to digital pictures but will record the build (will even post them if it works!) Thanks for any interest...Dave
  9. Mark, Harold....thanks Thomas..... have'nt looked into that but will certainly now....thanks
  10. Looks like parts of arizona, I hope to see it someday:) Ditto spending time with another smith (or aspiring). I eventually lost motivation when my son and shop partner went to collage. I have decided to join a local group to relight the forge. Best of luck.....Dave
  11. I was here for a bit as tinbender and could not seem to retrieve the password so a new account with my name was the easiest:) The forum seems to have a very positive feel to it. I'm happy to see that and send thanks to those that have made it this way (not that there was anything wrong before). Frosty I am happy to see you are still kicking and have not lost your sense of humor:) Dave the Lucky
