3lbhammer Posted July 6, 2010 Share Posted July 6, 2010 I plan to build a “Appalachian power hammer”. I have been looking for springs. I have found lots of new spring of different lengths and sizes. Most are sold by the weight of the trailer that these will carry for a few hundred pounds to several thousand pounds. What would be the right size for a 30 to 50 lb hammer.? A set of new trailer springs of about 25 to 30 inches with three leafs cost around $50. or less with a weight of 750 to 1000 lb. Quote Link to comment Share on other sites More sharing options...
unkle spike Posted July 6, 2010 Share Posted July 6, 2010 I bought by dimension. I bought a 60 inch by 3/8" leaf spring. I cut two 15 inch sections for the top and bottom leaves, and used the 30" for the main spring. I bought mine at a local semi truck and trailer place. It had 4 or 6 inches of arch which was of course divided in half when I cut it in half. I want to say I paid around 60 bucks for it new.

arftist Posted July 6, 2010 Share Posted July 6, 2010 My seventy five pound hammer uses 3 leaves, 5/16x 2 1/2. I bought them at a truck sping shop and had the owner straighten them cold in his huge hydralic press. If he charged me to straighten them, it wasn't much.
