Most accurate Bevel Jig out there?

I want to be able to quickly, accurately and exactly set 2, 3, 4 and 5 degree angles for really good looking bevels. I bought an inexpensive one that is working but loses its angle during hard grinding. I want exact angles and sturdiness. ideas?

You could make dedicated jigs for each degree you're looking for with some angle iron and bolts ☺
 
Accurate angles does not a good looking bevel make.

This is why I have allways HIGHLY recommended learning how to grind edge bevels by hand. Once you learn you will be surprised how accurate you can be. I honestly only see jigs/machines being practical for large batch runs. But single or just a handful of blades is easy to just bust them out by hand.

I would agree with this if exact angles are what your after but jt is correct. Keep in mind that the angle of the bevel changes if you have a distal taper so fixed angles are of little use.

This jig I made works really well, is very quick to change the angle and as the blade isn't fixed it can still be adjusted by hand to stay perpendicular to the belt. It only needs 1 adjustment rail not 3 like I have.

 
There are makers I sell to that make sets of knives and they purchase extra grinding clamps along with an extra Bubble Jig so they don't have to change angles so often. The angles provided: 2- 2 1/2- 3- 3 1/2- 4- 5 10- 12 degrees. The angle wedges can be stacked to give you other angles you might need.
PM me if you have questions. Fred
 
I can recommend Fred’s bubble jig. Works the trick to have you consistently at the correct starting angle without locking you in so that you can’t properly deal with the sweep at the tip or a distal taper as can happen with a fully rigid jig to table setup.

Picture of your jig will help us to see what can be done to improve that jig . About making one with exact angles and sturdiness..it can be done sure .BUT best thing is if you make your rest work adjustable and make and use simple fixed ,90 degree angle jig .....

I can grind every possible type of bevels with jig , even convex one .If anyone think that it is easy to grind with jig .....is wrong ! If it is easy please make video clip and show us both side :thumbsup: Even with jig you must to learn how to use it and still grinding depends on you not on jig .Jig help BUT it's me who drive it/control it :) I can t learn free hand grinding .I can grind one side but other side is nightmare even after 5 years ..:D Hollow bevels I can grind free hand on both side :p
 
I use the bubble jig myself and I love it. It teaches your hands to stay steady and it really helped me visualize the angles. I just suggested the cheap iron angle jigs because one can make it set for a specific angle and it won't change unless the user lifts it off the work rest.
 
I mainly use the bubble jig, but there are some knives that I use a jig on. DD work rest makes a really good one. He also makes a file guide stop for it to help with plunges.
I use it for a specific knife that I make for a local store because its important for all of them to be exactly the same.

how is it losing its angle ? can you post a pic.

Here are pics of the Jig. after 5 mins or so grinding screws loosen and If I don't constantly re-identify the angel and reset the screws; I will get bad/uneven/wavy angles.

Use lock nuts on both sides of your angle adjustment. It'll require a wrench to make any adjustments, but will be very secure.
 
i was thinking a stiff spring between the blue knurled nut and the forked part should keep them from loosening.
 
Why do you have two adjustments? Vertical Bolts against work rest and the knurled knob?

The bracket the knurled knob is against isn't square so the knob and nut are only contacting at the corners. Any flex in that bracket will cause the bracket to straighten out and possible spread apart and the knob or nut will loose tension and possible loosen off. A piece on angle with the two adjustment bolts would be much more secure.
 
I think that vertical bolts serve as handles to hold jig not for adjust .No reason to have two type of adjustment at once
 
You can try this ............cut where is red line , drill new hole where is that red circle , straighten that part as it is on second picture .No reason to be bend like that if you work with 2-5 degrees angle , that way that two nuts will stay tightened .... As it is nuts have almost not contact with that part and you can t tighten them properly.

Anybody try that Moen knife grinding jig? I made a clone and am impressed with how well it works.

here around the 1 minute 50 second mark shows the use of it.
