oscer Posted May 21, 2022 Share Posted May 21, 2022 Hi folks, I recently bought a Service Diamond Hardness Tester at an auction. Can't find any info on it and it doesn't seem to work. I was wondering if anyone has one of these it's a model 8blp, the problem is that the loading handle will only turn a few degrees then it comes up against very strong spring or possibly hydraulic resistance any help would be appreciated.

Irondragon Forge ClayWorks Posted May 21, 2022 Share Posted May 21, 2022 Just wondering, what do you use a Diamond tester for in blacksmithing? Why is it posted in the heat treating section? Is the name Lois Small on the units tag? Quote Link to comment Share on other sites More sharing options...
oscer Posted May 21, 2022 Author Share Posted May 21, 2022 Hello, It's A Rockwell hardness tester, Louis Small is/was the owner of the company, I think. It also says Service Diamond on the tag. Quote Link to comment Share on other sites More sharing options...
