Blade bevel grinding platen for 72"

[benny_chapman]

Well after not being able to reliably get the hang of an adjustable bevel grinding jig, I switched to adjustable platen instead with heavy fixed angle jig. The weight gives good control, UHMWPE is the plastic layer for low friction. Platen is 10mm thick, blades get bolted to the jig (6mm tapped holes).
