Hello Andy and Ed. Indeed it seems like a good unit based on the price.
I want the unit to check mainly lobes on camshafts. We already have a Rockwell hardness tester but the problem is given it's construction I need to make destructive testing with individual lobes because of the shape and lenght of an entire camshaft. So the idea was to find something more handy to do the testing. 2017-10-19 11:42 GMT-03:00 Ed <ate...@mwt.net>: > On 10/19/2017 06:35 AM, Leonardo Marsaglia wrote: > >> Hell to all. >> >> I came across this leeb harness tester on Ebay and I would like to know if >> anyone on the list has had any experience with such a device.
