Ricka Posted December 29, 2021 Share Posted December 29, 2021 Hi all, Reading forums like this encouraged me to want to build a PH. Since I wasn't going to find anvil material in this area I approached a couple of grading contractors and was given a worn-out idler from a dozer track and a couple of lower track rollers. I filled the idler with well-compacted sand and welded it all together. As near as I can measure the anvil weighs about 650 lb., plenty for my tup which weighs a little under 50 lb. I already had all the rest of the parts so it basically cost me a few dollars for welding rod. Nothing special but I thought it may give some ideas to guys who are having trouble locating anvil material. Rick A Quote Link to comment Share on other sites More sharing options...

ThomasPowers Posted December 29, 2021 Share Posted December 29, 2021 Is there enough spring there to give it the "snap"? Quote Link to comment Share on other sites More sharing options...
Ricka Posted December 30, 2021 Author Share Posted December 30, 2021 I just finished it; can't say yet. It's the spring I had and may have to be replaced. It seems to hit well to me but I'm no authority. I posted mainly to present the idea of putting together an anvil out of available and free objects, which seems to be the biggest challenge for prospective builders.

lary Posted December 30, 2021 Share Posted December 30, 2021 Rick, Got any pictures from the side? i was trying to figure out how the piece that is the hammer is guided. I built mine from scratch without plans so I get a kick out of seeing others. So it looks like the idler is the base? That mite help to make it more stable with all that weight down low, most I've seen use a 1/2 inch plate. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted December 30, 2021 Share Posted December 30, 2021 I generally suggest people use powerhammer(s) a LOT before trying to design their own. Just as I would be hesitant to drive a car designed by someone who has never driven one. The way around this is, of course, follow the exact plans for a PH designed by an expert and proven in by use.

Ricka Posted December 31, 2021 Author Share Posted December 31, 2021 Lary, Only took the one pic. The hammer is the works of a walk-behind dirt compactor. It amounts to a piece of heavy wall pipe surrounding ball bearings and a shaft with a big piece of steel welded to one side to give it the shaking motion. It's got a piece of 1/2" steel plate welded to one side by which it was mounted to the base of the compactor. The guides I made are lined with strips of phenolic resin and the edges of the plate slide in these. Yeah, the idler is the base, 28" diameter; I figured it would help alleviate the rocking tendency of the counterweight on the car wheel.
