there has got to be a better way to set the bevels then free hand like im doing atm. It realy sucks and im so slow at it that i can do a better ,faster job with files and sandpaper. i looked at the jig in the newbie tutorial but dont understand the concept of it at all. I know somewere out there is a better easier way of doing this. any 1 with a better way i would appreciate it any info.
 
That link Matt posted: I have seen numerous similar designs so I think many people use such a jig on a belt sander.
 
sweet, just what i was looking for. looks very simple to make. wonder why they made a welded piece instead of just using some angle iron. going to make me one of those tommorrow. thanks again
 
I had planned on using angle iron as well. I believe one of the major assets in this setup is the large plate used as a tool rest for the jig

Notice the two machine screws..one at either end..to hold the knife in position as the downward pressure of the belt bears on the steel. If you slot these three holes continuously...so that it is a slot rather than three holes... you will have better control of exactly where your horizontal line is. I made one with holes a changed to the slot and it works better. I use wing nuts and small bolts instead of machine screws.
 
You're welcome Fred :thumbup:. I looked for the link you posted but found the other and figured that pointing people at your website was an even better, and more detailed solution (I should have posted that link also).

I think that Fred's bubble jig is a very cool tooling solution, although I don't understand it completely (the cotter pin confuses me. When I make one I'm sure it will become much clearer to me.), I can see, from the pictures, how and why it works so well and solves the vexing problem that so many have before their muscles acquire the agility and memory to grind well freehand.

I LOVE seeing and dissecting these ingenious solutions to toothgritting technical problems.There are so many different ways to attack each one................ Witness all the different homemade and customized storebought grinders that appear and the surface grinders modified to use 2"x72" belts as well as wheels.

I reckon you would need to get a pretty thick hefty profile of angle iron to ensure its rigid enough to prevent/ reduce chatter. Thats possibly why the guys choose to rather weld two thick plates together?
 
This jig will give you smaller width of flats closer to the tip, where blade curves. Not that it is a bad thing. Some people even prefer it to the regular flat grind.

You can use this jig of course but you also should learn to grind free hand IMHO. It'll take some time but in the end it'll give you more freedom than all jigs combined.
 
Is this guy wanting a jig to grind flat grind or something that has quite a bit of flat to the blade or very little?
