I believe that nothing works better than practice and nothing is worse than giving in to the temptation of taking a peek while you are working. Hollow grinds always come out best for me when I simply keep going until I have finished the grind because getting it back on the wheel in the same angle and position as it was when you pulled back is very difficult.

George is right but here is a tip that helps me, On the first pass I use a coarse belt and a lot of presser to make a good hollow on the first pass, this gives a good track to follow and the rest is practice, practice, practice. Gib

Couldnt agree more with the first two comments. Like Gib said " Good coarse belt and lots of pressure " That has helped me a ton. Ive hollow ground around 15 knives now and each one gets better and easier....practice, practice, practice.

Metalking,

I don't know what your budget might be but http://www.ccinstructionalvideos.com/hollowgrind.htm from the reviews is a #### good investment. It might help, I have the Hunter video that Gene originally came out with and even though I don't do hollow grinding, just the stuff he covered helped a large amount.

Sir. If you have not hollow ground too many blade, it seems like it is difficult to "Feel" what the wheel is doing and where it is making contact on the knifef.
One thing that will help you a lot is to have a Veriable Speed grinder. If you are starting to learn to grind, and are using a single speed grinder that seems like it is running like a demon, all I can say is "Yes it is difficult". Using a variable speed will help you slow down that new 50 grint that can eat up your blades in no time.
Slow it down to where you feel confortable, and of course like everyone is telling you "It will take practice".
Sometimes after years of grinding you will get in front of that machine and it will seem like it is the first time you are on it. Not having the feel of where things are toughing.
Do not use jigs, teach your hands to do the work, and you will be able to do much more.
Good luck and hope to see you at a show someday.
Ricardo Velarde

Talking

You can also "practice" on wood. That way you don't ruin your blades.
Also by working with wood you can save money (wood doesn't eat the belts). I went up to the local craft store and bought some basswood then profiled them to shape before hollow grinding. The kids love to play with them and if they break they just go and grab another one (I have about 3-4 dozen in a box).
I have also used playwood, but it doesn't make as nice of a "toy" for the kids.
Just my thoughts.

I can't help but to peek at my grind, so I paint the sides of the steel with dyem really makes your grind lines stand out after you get your groove started.
