Baler knife sharpening jig
Not happy using a hand held grinder and flap disc, the ground surface gets beveled too easily.

Vertical post slides up to set the angle, held by a grub bolt. Grinder leg pivots on a spare strap hinge that was lying about.

Blade is held in place on the top plate with a mole clamp and positioned by a couple of welded on bits of cut off set screw that were beside the vice.

Since the grinder pivots around the arc of the blade, and it's held flat at the set angle, you get a flat ground very sharp edge (look closely at the grind blade picture and you'll see the remnants of the bevel I'd ground out. This blade took a couple more grinder sweeps until it was sharpened).
The metal isn't overheated using the battery powered grinder and a 60 grit flap disc.
Away to bale the first of a neighbours silage of the season in the morning
This must be a perfect example of a bodge: looks like shite, made from scrap & works beautifully, Highly Commended
