Grizzly "Dr. Ashby" grinding jig

[SOS]

For those that are sharpening challenged like me, here a basic jig I made to change Grizzly's grind angle to 25 degrees as Dr. Ashby's recommendation.  Cut a 2x4 off on a table saw to 25 degrees.  Trace the blade with one angle flush and chisel out some relief for the ferrel to sit flush.  Then position half of a 2"hinge so the screw holes will clear the blade and mark the holes.  Then drill for 2 threaded inserts from Lowes or Home Depot and get appropriate size round head machine screws.  Below is the jig from a couple of angles.






Position the blade flush with the edge:


I place the blade flush with the sanding disk and adjust the miter so it is flat to the side.  Helps keep it aligned.



Turn on the disc and feed it slowly a little at a time so not to overheat it, until you've cut an even edge.



And "Voila".



You can even make a little angle guide to help re-do the tip.



I then use a slightly modified Gatco sharperner for final dressing and polishing of the edge.

Good luck.

One more suggestion - before grinding, file the back side of the blade perfectly flat and free of any burrs prior to grinding.

Thats pretty cool and easy.

Built me a SOS jig to try on some unground Stos 160 gr heads I had laying around... the area right at the junction of ferrul metal and broadhead metal isn't as smooth as SOS's, but I am still adjusting the jig...

Gotta say, the Grizzlies are looking good on my GT's for Africa in two weeks...



And they shoot pretty good with high FOC.  Three almost touching - the one slightly to the right is a field point for comparison....



Needless to say, I quit trying to shoot groups after that.
