Nail removing gun - GIF

[Toolmaker51]

Safe enough for me, long as operator stays awake. Foot-pedal and housing over linkage to jaws; without usual crop of OSHA encumbrances. Asian characters [lower left] made things clear, time invested time to build a machine recycling near useless lengths of pallet grade material. Probably nails too. Cannot visualize profitable use.
What a fabulous resume entry...Harvested mountains of scrap; yesterday, today, tomorrow, and day after that. Kept my fleshy bits out.

Finish library visit, all the while trying to imagine 'why'. Maybe, not knowing where all the pelletized fuel comes from, wagering that output is hammer milled or shredded. But they'd eat those nails, and filter over a Bunting/ Eriez grate or disc.
