Author Topic: Another way to grind a Griz (Read 507 times)

I really hate spending an hour on each head (Griz 190) trying to change the angle of the bevel ala Ashby. There HAD to be a better way. So... this way works for me. The longest part of this was constantly stopping to quench the head so it didn't overheat. Still only took about 1.5 minutes per side.

I added a wire guide to the side of my belt sander. It is a spare Lansky wire.

It is epoxied to the side so the wire is level with the belt. You can also just hold it there with your hand if you don't want to glue / screw / or weld it in place.

Then I modified a spare Lansky device by grinding it on a taper, so it can hold the broadhead 90 degrees to the axis of the device.

then I insert the Griz, trying to make certain it is pretty close to 90 degrees

Now slide the 25 degree slot onto the wire guide

place the broadhead down on the belt (turn it on...OK ?)

Alternate between grinding and quenching, I used a tin can with cool water. I also used a wooden piece to press the broadhead into the belt in the places I wanted pressure. It gets hot fairly quickly but I did not scorch any of the heads.

After a few sequences of grind and quench, turn the blade around in the device and do the other side. then use the device as a holder to grind a tanto-like tip.

Now go ahead and finish the sharpening. I am FINALLY able to get these dudes really... like actually shaving sharp..

Hope it works for you too.

Not that I am going to a single bevel head anytime soon... That is a good set up Chuck. Should helps some folks out.

Still like my Razorcaps though!! Best of Luck to ALL!

Ingeneous!

What a brilliantly simple idea

(although I'm sticking with my Magnus 1s

)

Good idea!

After talking to Ron (sharpster) about sharpening Grizzlys, I've been using a belt sander with his broadhead sharpener.

I am guessing this would also set a grind on any straight double bevel head as well. It was way too easy... something must be wrong....

I resharpen my single blades like this when I lose the shoulders with Sharpsters BH roller kit but don't tell Biggie, I told him I free hand a 25 degree angle on a diamond...a wore out belt works great

TTT

For those that are watching... I placed the jig / broadhead onto the belt wrong way down in the photo. The belt was not moving and it was for the picture only, but, please watch which way you place the broadhead so you grind the correct side.

I have had to start a note book to hold all the great ideas that come off this site.

Simple and effective Thanks

Anybody have an extra one of these lansky devices they would be willing to part with for a good price?

ChuckC · « **Reply #12 on:** July 30, 2008, 05:34:00 PM »

tradwannabe no special secret, I hold the Lansky as a handle and touch the tip to the moving belt. LIGHTLY ! If you do a dry run first, it will be pretty straight forward.

You guys need to improve on this and report back.

I bought some el Grandes to play with and got tired of trying to shape even the first head. You know.. laziness and mothers, or inventions or some such. What I like is that this SHOULD also work on any straight bladed head, single or double bevel. I have not yet tried it on other types but as soon as I have time, No Mercy heads will be run thru it. They should be even faster !
