Thanks. Can't tell you how long I searched for an easy D.I.Y. method to set grinder platform to a specific angle without having a tool known to have the desired angle. Marker + trial & error is crude; useless w/o reference tool. So grateful for your video. Smart people like you inspire me to remediate my lack of education.

And thank you for leaving this comment. It's what makes creating the video worthwhile. I have no plans to be a KZbinr. I just hoped to reach people like you who appreciate the idea.

Love this! Just learning to use the wolverine system and dont have all the extra bits and this makes it more accessible! And love the diagrams! Most helpful! Thank you!

Paul, excellent video presentation. Turners as round the world should be using the methods and ideas presented here. One of top 3 videos I have watched. Thank you for sharing!

Math teachers around the world should show this video as a way of answering the question "when would we ever use this?" And they could start by showing the price of the commercially available jigs for setting these angles while also pointing out that those tools assume that the gouge projection and jig angles are constant whereas Paul explains how to vary them for different use cases. So much better/empowering to know the principles than to be a captive of someone else's design! Bravo Paul, bravo!

Thank you Paul for a clear concise explanation. Looks like an excellent method for setting grinder angles not just for bowl gauges but adaptable for chisels, plane blades and other applications.

And thank you, Paul, for your note! First one ever :-) and I really appreciate it. Yes, you're right. This approach will work for any shaping on a grinding wheel that needs a set angle. You can even combine it with your own platform.

Wow. You just opened up a new world for me. Ive been struggling for a bit figuring out how to dial in exact angles without buying allll the jigs. I'm a frugal woodturner so I truly can't thank you enough.

Thank you for your comment! I am pleased to hear that this video has help you. As Kent at turnawoodbowl.com says, "Happy turning!"

Great video Paul. I use a similar method for setting the platform angle. For a 40 deg bevel angle, I set my protractor angle to the complementary angle of 50 deg and place the protractor on the platform with the adjustable leg pointing to the center of the wheel (motor shaft). Complementary angle is 50 + 40 = 90 deg. The tangent point is at the edge of the platform and the grinding wheel. I'll try your jig for the Vari-grind attachment. Thanks

@GCS12342 Thank you for your appreciation and comment! We all benefit from sharing the various ways we can accomplish a task. To be honest, I had to go out to my shop to figure out a way to do what you describe. I think I get it. Your approach has the distinct advantage of not requiring a jig. You require the platform to be almost touching the grinding wheel, right? And you have to line up the foot/leg of the protractor with the center of the shaft to get the complementary angle to work. That did not seem as easy as the approach that I settled on, and described in the video, which can be done with your eyes closed and the platform at any distance from the grinding wheel. But it certainly works. I hope I have your method right. Thanks again for sharing.

Great video and great concept. Since precision is key, made models of the two different styles of jigs (with/without Vari Grind) and made 3D models that I can then use my 3D printer to print with a lot of precision. Works like a charm. Thanks for the video and the information!

Thank you for the video, it definitely answered a few questions I had and hopefully I can spend more time turning and less time grinding my gouges to nubs. 😊

Great method. I tried it with my wolverine jig today. I shaved the vertical leg with my plane little by little to fine tune it to 35 degrees. Thanks Paul.

Experiment results. I set up and ground a bowl gouge and a spindle gouge using the Wolverine Grinding System and then attempted to grind the same gouges on the Tormek Grinding System using their set up tools and their set up procedure. I could not duplicate the same grind, particularly on the wings, using the two systems. I experimented with multiple changes to the set up procedures and could not duplicate the grind. The Tormek seems to be a superior system but it is more time consuming to set up and maintain. It creates the desired bevel angle with machine shop precision. And, as a plus, I like it's ability to strop the gouge after the grind. The Wolverine system seems to be a quicker approach for a quick resharpen while turning. However you need to start with the Wolverine System and Veri-Grind tools to establish the initial angles and stick to one system. You can not go back and forth between the two systems.

Thanks for sharing. The geometry of the swing in the two systems is different, so you will not get the same wings, as you observed. It is possible to go from the Wolverine to the Tormek when you focus on the cutting edge and not the whole bevel.

Thanks, that was helpful. I made a system similar to the Pro edge, so some ot this does not apply, but watching your video gave me a solution to grinding to a repeatable angle on my system. I'm thinking that I can zero a digital angle gauge on the platten and measure the angle to the gouge (maybe with the gouge clamped in a block and with a metal plate running parallel to the gouge to attach the gauge).

Thanks a lot for this precise , clear information, it’s pure knowledge. Being in Belgium ! I’m converting the inches to mm. The 1.172 inch is 2.97688 cm, can I round it to 3 cm? Since making wooden bowl is not a rocket science, to do the exact dimension, will have to make it done on a metal lathe.

@RuudInTheWood 2 ай бұрын

You are welcome @jmselvon! Doing everything metric works the same for the formula. Just enter your grinding wheel radius in cm. And I agree, turning wooden bowls does not require high precision, so in your case 3cm will work just fine.

How would you calculate the sizes of wood needed for a 150mm size grinder?

@RuudInTheWood 5 күн бұрын

As long as you are willing to stick to mm, the same way. Given a radius of 75mm, for 60 degrees, 75*(1-cos(60))=37.5mm or for 40 degrees, 75*(1-cos(40))=17.55mm.

@kc2972 Ай бұрын

for every different size gouge do you have to make a different jig system because each gouge would be a different diameter therefore wood spacers would be different???

@RuudInTheWood Ай бұрын

Yes, that is correct if you want to be exact. This situation is the same for all fixed angle jigs, though it is rarely acknowledged. The differences are small enough that a lot of people won't bother to make multiple sets. They will just choose a compromise width.

@RuudInTheWood Ай бұрын

Two additional thoughts: I use mostly 1/2" bowl gouges. I only grind my 5/8" to 55 degrees, so that would be an additional jig for that larger gouge. Alternatively, I could just shim the bottom of the tongue of the jig (the surface that touches the grinding wheel) by 1/8". That effectively makes the width of the spacer 1/8" less.
