  1. Well, it's finally finished. I tore it down Saturday and the wife cleaned and painted it for me. Great gal that one! I ran out of grease zerks and will have to make a run to TSC. I believe the lead shrank a bit after I welded in a "V" shaped stop inside the hammer right after pouring the lead in. I have to figure that one out yet. It doesn't seem to affect the awesome striking power any. Here's the video I made right after re-assembly. I love the control ability. Now to make some specialized tooling for it. Stitch
  2. Well it's almost done. I have a few more parts to make and some more welding to do. The column to slide housing will be welded in today and the motor wired. I am making my dies from 4140 to start with. The laser cut patterns I made helped a lot. I am curious, has anyone filled their columns with sand to help with the noise? Any noise reduction would be a bonus. The wife has offered to do the final clean up grinding and painting. Thanks all!
  3. Hi, Can anyone who has built a Clay Spencer\Ray Clontz power hammer supply me with the lead offset wheel weight? I do not have any way to make the mold and melt the lead. I will happily pay for one! Thanks guys, Stitch
  4. I’d like to hear a little discussion about the merits of both of these hammers. The swing-arm type I’m referring to is the one with the adjustable height head. I’m going to build one sometime in the future so I have been pondering on this a bit lately but would like to hear from any one who has used either or both. Most of the builds I remember in the last few years have been for the inline type with the explanation that you do not have to make any adjustment to the hammer to when you switch out tooling. However I have talked to two professionals who said the very much prefer the swing-arm type. The reason begin that they hit faster and harder and so they can get more work done in the same amount of time. If I recall correctly the linkage in the inline design is less efficient in converting movement of the treadle into movement of head and thus take more time and energy to accelerate the head than the swing-arm design. Also the return stroke on the inline is longer which adds to the cycle time of a blow. One think to bear in mind is that a professional usually runs items in batches and will build their processes and tooling accordingly. Therefore the cycle time of the hammer becomes the limiting factor. A hobbyist will normally be making a one off item and using what ever tooling is at hand so adjustments to the hammer may become the limiting factor. I have used both types, but only for a short time each, and my experiences matches the above. It seemed that the inline felt heavy was hard to get moving and would wear you out if you had to use it a lot. Where as the swing-arm hammer was much snappier and just required less energy to use. To me the only time the inline is of a real advantage is when you using tall tooling such as a punch or drift and you needed to switch the blow from the tool to the stock mid heat and can not afford the time to adjust the hammer. If any one has experience with either hammer or both and would like to comment please do so.
