ThomasPowers Posted February 25, 2014 Share Posted February 25, 2014 Magnetic as in attracted to a magnet or magnetic as in being a magnet? The latter would be a bad thing for a bounce test Quote Link to comment Share on other sites More sharing options...
norrin_radd Posted February 25, 2014 Author Share Posted February 25, 2014 Magnetic as in will stick to a magnet. It came out of an ancient mouse and I peeled the rubber off of it. Its actually a steel ball about .75 in dia. not sure how much it weighs but I wouldn't want anyone to throw it at me. Anyway that's all I have right now. So I read about the rebound test and one thing said to drop it from 10". So I polished off half a tube of pringles, cut a 1" slit up the tube and marked 1/2" increments up it, I had about 9 1/2" on the cylinder. I held it about 1/2" above it and dropped it several times down the tube and the highest it got on the welded on face was maybe 4.25". I dropped in on the exposed part of the original slab and it bounced almost to 5". So I guess the added face has about a 42% and the original face had 50%. I guess that should be good for a hobby anvil? Quote Link to comment Share on other sites More sharing options...
norrin_radd Posted February 25, 2014 Author Share Posted February 25, 2014 Dawned on me a few minutes ago that you thought I might have tried the rebound test with a magnet, that's pretty dang funny. Quote Link to comment Share on other sites More sharing options...
caotropheus Posted February 25, 2014 Share Posted February 25, 2014 norrin_radd Just go to the scrap yard, get the biggest bearing you can get, cut it with a grinder, extract the steel balls and make the test. There are lots of youtube videos that show ball bearing rebound tests on anvils. Quote Link to comment Share on other sites More sharing options...

I might even try to harden it some time in the future if I feel like its something I need to do. Right now I want to get the forge fired up and make stuff. In the process of fabricating me a "stump" out of that fat lighter beam too. Thanks to all for the great info on this site. Quote Link to comment Share on other sites More sharing options...
Sweany Posted March 2, 2014 Share Posted March 2, 2014 Hammers work for rebound test too Quote Link to comment Share on other sites More sharing options...
