We all know (or should) not to use a grinder on wood, plastic, etc.
I need help with finding documentation prohibiting the use of a grinding wheel on plastic. I've spent a couple hours going through OSHA, and All I found was under Ship Breaking, advising against getting wheels loaded up with copper, aluminum and bronze residue.
OSHA Regulations (Standards - 29 CFR) 1910.215(d)(3) does mention "free of foreign matter". Even Norton Abrasives was no help.
The problem is, I'm dealing with Shade Tree Knuckle Skinners and since our "Uncle" has a proceedure that details the use of a grinder to perform this task, (so it's gotta be good right?), I can't get any cooperation. To support my argument, I need something that spells it out in plain English...Dangerous! Do Not use to cut plastic!
We have about 1100 linear feet of these cuts to make, so I'm trying to order a Craftsman Twin blade carbide cutter to slice through an aluminum plate glued to plastic. Frustrating because they (us taxpayers), are spending a Billion bucks a week over here and I can't get a $200 tool to do the job safely and right.
Any guidance will be greatly appreciated.
