Say,a thought occured to me .What a person needs for a scabbard is a material that will stand up the rigors of the work involved plus not be to so rigidly made that it could damage the saw .
Obviously some thermal plastic or nylon material would be ideal .The problem is the fact the stuff is costly .
Aha ,the old dumpster diver has a plan . Often times parts suppliers to industry use a plastic type sheet spacer when shipping parts to say automotive companies and like industrys .Now these shipments periodically change and new methods of dunnage are devised .
What I'm taking about are shipping boxes that are designed to be loaded and unloaded by robotics . When the parts designs change the boxes also change as they usually can't be altered in a manner that will suffice .
It would make sense that this sheet material would be floating around someplace by the ton . Perhaps if a person investigated companies that deal in the manfacture of these "Hi tech " shipping boxes that perhaps a large amount of this stuff could be located at a price that wouldn't break the bank .Worth a try .
