gearhartironwerks Posted January 27, 2014 Share Posted January 27, 2014 Surfing the web one evening, I came across a youtube video by Trollskyy on bevel grinding. This guy works with minimal homemade tooling and gets it done. Then, I saw a video by the Blind Horse Knife Factory doing flat grinding as well. A youtube search will get you there. The concept of grinding is the same in both, but the Blind Horse jig is more advanced.So, being a geezer with a not so steady hand, I made a jig like the one in the Blind Horse vid and it works great! I'll post pics asap of the jig and grinder extension.John Emmerlingwww.gearhartironwerks.comSome pics of the jig.I milled a 3/8" slot to hold the blade. The platen is tilted toward the backing plate, and I just drag the fixture across the platen using a push sticknear the blade tip. This is incredibly simple and easy to use.Johnhttp://www.gearhartironwerks.com Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted January 27, 2014 Share Posted January 27, 2014 why not ad an adjustable angle setting to the base, rather than leave it 90 degrees and guess where it lines up? if ya go to all the trouble making a jig to just hold a blade, may as well lock in the bevel angel as well.

gearhartironwerks Posted January 27, 2014 Author Share Posted January 27, 2014 Steve, The platen on the grinder is adjustable so pretty much any grinding angle can be used. Total construction time for the jig is less than an hour, and a couple of bucks for al rems. It doesn't get much easier than that imho. I like the simplicity of it and anyone can make it.

Steve Sells Posted January 27, 2014 Share Posted January 27, 2014 ok , good deal, I had to ask because your 3rd photo shows it tilted up off the rest. Quote Link to comment Share on other sites More sharing options...
gearhartironwerks Posted January 27, 2014 Author Share Posted January 27, 2014 I should've been more clear on that. Also, I would consider making the jig using steel as I think the added weight may make the grinding easier. As is, the belt wants to tip the jig toward forward in the direction it runs. The push stick helps keep the grind even. John Quote Link to comment Share on other sites More sharing options...
Dodge Posted January 28, 2014 Share Posted January 28, 2014 I watched both vids. They make it look ridiculously simple; Especially the Russian! :) I made my table adjustable albeit wished I made it deeper. Now just 2" wide x 18"... Anyway, I also made a similar jig. I immediately was able to make scrap pieces with identical grinder marks on both sides. :ph34r: Quote Link to comment Share on other sites More sharing options...
windancer Posted January 28, 2014 Share Posted January 28, 2014 Trollsky is an incredibly bright man with many excellent videos on youtube. I made a couple of the jigs after watching his and other grinding jig vids a few months ago. Started with a wooden 2x4 and worked up to a 1.5 x 3 inch steel angle iron. The wider face rsets on the table. Made a much larger table for my KMG and these simple jigs are a huge help! I drilled the jigs and threaded the holes for 1/4 inch screws with lock nuts. To change the angle you just run the screw up or down and relock them. I left he bolst 3 inches long so ytou have a very stable place to hold while grinding.

basher Posted January 30, 2014 Share Posted January 30, 2014 Good Job. At some point I really must give this a go at grinding with a Jig. I have always ground free hand with no table on the grinder. I do a good quick job of it... But I find my wrists hurting. I think a jig or two may ease up some of the pressure from keeping hands locked in place.....

Rich Hale Posted January 30, 2014 Share Posted January 30, 2014 Basher I have a third tool in addition to my hands for grinding...a pot belly is a wonderful place to rest both of them. Quote Link to comment Share on other sites More sharing options...
basher Posted January 30, 2014 Share Posted January 30, 2014 Basher I have a third tool in addition to my hands for grinding...a pot belly is a wonderful place to rest both of them. I invested in one of those early on and use it as a hand rest and third hand for all sorts of stuff....... Quote Link to comment Share on other sites More sharing options...
Dave Budd Posted January 30, 2014 Share Posted January 30, 2014 I have always done my grinding free hand too. I use a stick with a ledge cut into it to support the blade and lock my arms into my waist for support. I've never had trouble with my wrists from grinding , maybe the pushstick helps with that? I did recently start using jigs for grinding small blades such as wood carving knives, the sort that are too fiddly to hold securely. It is a piece of angle iron and a small pair of vice grips. The work table can then be adjusted to give the correct angle. For these repetitive blades where I'll be grinding a dozen of identical angles the jig setup is ideal, but I find that grinding freehand for every other knife is just so much faster and more flexible :) Quote Link to comment Share on other sites More sharing options...
