Can anyone identify this tool?

admin

Picked this up at a garage sale yesterday for $5. It looks like it might be a knife sharpener jig for a planer knife but I'm not sure. I'd hate re-purpose it and later find out I could have used it for it's original purpose  Simply too many goodies to pass up  Attached Images

Reply:You guess right , old style planer knife sharpener.
Reply:It looks very similar to a fixture used for sharpening blades for sod cutting machines. We have one in the shop. Obviously you are missing everything else, i.e the rack system with the grinder that rides side to side.Granthttp://jackalopefab.com/MM210Synchrowave 200DXMiller XMT350 w/60series feederMiller Bobcat 250 with SGA 100 and spoolgunHTP PlasmaFull Machine shop with everything

Reply:Coming out of a small engine shop it was probably part of the grinder used for putting the initial hollow grind on bed knives for reel mowers or maybe sharpening any other flat blade, like on a sod cutter.  I had one many years ago in my shop that would take a bed knife up to about 16".  A lot of the old reel mowers like on Leave It To Beaver were 12-16"  so if that's the size, maybe that's what it was originally made for.  It could have also been part of a lapping or back-lapping machine and held a bed knife while you lapped the reel.  The fine adjustments on it make it look like it could have been used for that as it's critical to have an even lap.  That bolt on the left side looks like a depth adjustment.  The grind mark could be from years of spinning a reel with lapping compound or a grinding wheel.  It's neat whatever it is.

Reply:If you can lose the handle you could use it to put any straight blade for anything in a Blanchard grinder with that and get unreal results.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
