Bubble jig review

It's kind of the other way around. You start at a 15 degree angle. And then work your way down.

But if you felt confident that you could grind to the middle.....and you have a VERY steady hand then I dont'see why you couldn't just start with a low angle.

I'm not going to though. I use the jig all the time and it works GREAT just as Fred intended it to be used.
 
I've done a few 1" to 1.25" tall small knives lately. I put on the 4.5 degree and grind until I hit the spine. I'll cheat the bubble towards the near line or the far line on the gauge depending if I need more at the edge or spine, but I'm not changing degree wedges during the initial grind. I only use the jig for the initial grind pre-HT. After I set the bevel, I'll do the rest freehand. I only set the bubble once per knife.

Don't forget it does Clips very very well too!

If you are a beginner at using this fixture, go through the progression of angles to get to the final bevel angle. You will learn a lot by doing this exercise.

If you are grinding a wide blade, such as a 2 or 2 1/2 inch there is an advantage to going through the angle sets. Here is a link that will help to explain why this is the case. http://www.bladeforums.com/forums/s...rogressive-blade-grinding-or-whats-your-angle

What Darren says is true; many makers who use the Bubble Jig use one set and cheat the bubble; I think I may have suggested this to Darren. I think most people who use it for a bit, will take the clamp off after they have set the bevel. Once you have a flat surface to work with its very easy to finish.

dperk, We are formulating a plan to get together in Jan, here on the hill. Burton, Moon and Ed and some others. If you are interested, I'll post you when we have a date set. Have a great holiday, Fred
