macbruce Posted July 12, 2014 Share Posted July 12, 2014 Been working the past few weeks on a KZ controlled 200lb utility hammer, a sort of keep me busy in between jobs project hehe....groan :P Still lots of finish work to do......Foot treadle,welding,drilling,grinding but I tested it yesterday and it hits snappy hard. Can't wait to use it............... B) Quote Link to comment Share on other sites More sharing options...
Jim Kehler Posted July 12, 2014 Share Posted July 12, 2014 You know we're waiting for some video B) Quote Link to comment Share on other sites More sharing options...
macbruce Posted July 13, 2014 Author Share Posted July 13, 2014 You and me both, I was mainly just trying the single blow yesterday and it hit good and hard even with halting the ram 4-6'' above the bottom die....gentle too if I chose....... The reciprocal action has to wait until I get the foot treadle dialed in which I'm doing today. Here's some stills of the fabrication for now.......

PaulKrzysz Posted July 13, 2014 Share Posted July 13, 2014 Looks awesome. I'm also waiting for the video. Quote Link to comment Share on other sites More sharing options...
metalmangeler Posted July 13, 2014 Share Posted July 13, 2014 I am very interested in the following details, air pressure, cylinder size, air consumption, (especially cycling) how it hits compared to a bull. Quote Link to comment Share on other sites More sharing options...
macbruce Posted July 13, 2014 Author Share Posted July 13, 2014 Fortunately for me Ken Zitur has already done the R&D on an old Bull Hammer so I knew the configuration would work. I've talked to Kenny allot lately and he says the little (90lb) converted Bull is a favorite of his but I couldn't feature building something less than 150lb+ using a $1500 control. The cylinder is a new Wolverine hydraulic from Surplus Center 3''x14'' and has been modified inside and out but it only cost $100 compared to $ 450-$850 for a comparable aluminum air cyl,,,,,,,,A steel air cyl would have cost even more. http://www.youtube.com/watch?v=Mbh3-xG_byA..........http%3A%2F%2Fkensiron.com%2F Quote Link to comment Share on other sites More sharing options...
E.F. Thumann Posted July 13, 2014 Share Posted July 13, 2014 I just noticed in the video that the treadle reciprocates pretty violently on the "continuous" mode. Has Ken found a way to mitigate that? Seems like it would be distracting/disconcerting at best. Ps, congrats on the new hammer! Quote Link to comment Share on other sites More sharing options...

macbruce Posted July 14, 2014 Author Share Posted July 14, 2014 Details, details......Couldn't bear the thought of working on my knees to drill,do more welding,grinding and fit up the treadle so......I love my crane...............
