Pit Bass Posted January 26, 2004 Report Share Posted January 26, 2004 Hi Guys. Is there a scale to rate hardness of a soft plastic bait ? I use calhoun plastic with no additives. How would that rate on a hardness scale? Thanks for any help ! Quote Link to comment Share on other sites More sharing options...
Delw Posted January 26, 2004 Report Share Posted January 26, 2004 Theres a scale you can buy called a durameter(sp), however the time I needed one for machining plastics and rubbers its cost was over 12k. Granted it was for the areospace industries Something tells me I said the wrong scale now.... correct me if I am wrong. Delw Quote Link to comment Share on other sites More sharing options...
alsworms Posted January 26, 2004 Report Share Posted January 26, 2004 In my opinion, Calhoun plastic is very similar to Lure Craft 536 formula; just slightly harder. But it DOES pour easier and makes a nice quality bait. I have read about durometers in measuring plastic hardness, but I have no idea how to use them.

Tubeman Posted January 27, 2004 Report Share Posted January 27, 2004 Durometer...a durable thermometer ?? oh that was bad I have mixed my own hard/soft formulas using a base plastic (ie Calhoun Tube) then kept track in terms of how much softner is needed to create a plastic suitable for worms/jerkbaits/chunks/quiver sticks...I think I have 4 formulas set so that the bait in question always has the hardness/softness I require. This takes some time and effort as well as precise measurements, otherwise...you look like this Quote Link to comment Share on other sites More sharing options...
