started this project around the end of august i believe, and managed to get it done about a week ago. instead of the normal tube in a tube construction of typical tire hammer tup/guides, i went with a 45 degree dovetail guide and ram, just to keep things as compact as possible to fit in my narrow and relatively low shop. i also deviated from normal tire hammer territory in the rotating assembly and crank sections. Instead of the trailor spindle i used pillow blocks and a 1.5 inch diameter shaft, in which was mounted a hub to carry the spare tire. The crank assembly is entirely separate from the wheel and hub, keyed to the shaft and removable allowing for replacement/rotation of the tire and rim in the future. Another noticeable difference, and the last major one, is the leaf spring dupont linkage (though i dont know is that still counts as a dupont) which i made by splitting a brand new small trailor spring and mounting each half in the orientation shown. a big consideration when building the hammer was the ability to disassemble it into pieces that could be moved with a dolly into the shop, so each part (except the anvil) is under 200 pounds. so here's the specs: tup weight is about 35 pounds, anvil is near 400, power is from a 1.5 HP single phase motor with a 1.5 inch pulley, the whole unit probably weighs about 1000 pounds, aand stands just over 7 feet tall. i will take more detailed pics tomorrow and dig up some progress pics as well. but i can honestly say that im extremely happy with its performance thus far!
Well, I've spent enough money on supplies that I decided it was time to start a thread about this. I've been slowly planning out this build, and am finally pulling the trigger on some materials. Last week I brought home this used motor to power the beast, 1.5 HP industrial motor, single phase, 220 v. Then today whilst wandering the scrapyard I found the right hunk of steel for the anvil, 9.25" dia steel, 3' long. Weighs in about #700. That's all for now, I'll keep ya'll updated as I slowly get together the stuff to start the build. Stephen.
