How to Sharpen a 40-40 Gouge

[@timofeyzhukov-khovanskiy9173]

This is great! Also if you want a little wing for scrape you can also swing back a few times and rotate the flute the other way too

[@docwade3409]

Very well explained. Thanks for taking the time!

[@WilliamLancaster-tg1ze]

Doc Wade thanks!

Can to comment on the limitations of 6” wheels?

[@WilliamLancaster-tg1ze]

I have never used a six-inch grinder. Most woodturners use an eight-inch slow speed grinder. I suppose you could adapt.

Ron Brown created a jig to use with the Veritas to make a perfectly clean 40-40 gring... It's fantastic. And I don't need that huge expensive Stuart Batty platform. Love Stewart and what he did for turning... but thankful for Ron... figuring out the angles needed so you can use a jig.

Hi William, What grit CBN wheels do you use for this?

[@WilliamLancaster-tg1ze]

I use 180 and 220 grit wheels, but only because I got the 220 on sale. Better choices would probably be 80 and 180.

[@desertblbuesman]

Can that grind be made with a one way jig?

[@WilliamLancaster-tg1ze]

no, but I just heard today that a jig is now made for the 40-40. don’t know by whom.

[@robohippy]

There is a jig by Bob (?) Brown, which uses a 3 inch protrusion. I know there is a thread or 5 about 40/40 gouges and how to do them. There is another set up that uses the Wolverine set up, and you can find it on the AAW forums under tips and techniques by Dennis Gooding. Once I learned to do platform sharpening, I quit using jigs. Really fairly simple, and far faster than the jigs.

[@markhollingsworth3097]

What's the square jig you used about a minute in to set the angles? So you have a link to this?

[@WilliamLancaster-tg1ze]

It’s a Stuart Batty angle gauge #1. You can buy them through Woodworkers Emporium in Las Vegas. I use mine a lot.

[@desertblbuesman]

Is the 40 40 grind just for bowl gouges?

[@WilliamLancaster-tg1ze]

It can be used on spindles, too. And, you can use it like a skew in making a tenon if you keep the sides straight.

[@lagswitch8525]

At 40 degrees here I'll post a Stu batty video link that may help you guys understand

[@deanmccall5023]

Except the angle down from the top of the flute isn’t what the 4040 is all about. It’s making sure that the wings as well as the nose are both at 40 degrees.

[@WilliamLancaster-tg1ze]

I never heard this before. I am just passing along to you what I learned from one of the top two 40/40 advocates in the US.

[@deanmccall5023]

@@WilliamLancaster-tg1ze that’s the way that Stuart batty describes it.

[@WilliamLancaster-tg1ze]

@@deanmccall5023 Interesting. I sent Stuart an email about this, but have not heard back from him. Maybe there are two ways of thinking about it.

[@deanmccall5023]

@@WilliamLancaster-tg1ze I would like to know the answer as well. I am now starting to wonder if I heard wrong. I know there has to be a down angle on the top side, but the way I understood it was the nose and the sides were both 40, hence the 40/40

[@WilliamLancaster-tg1ze]

@@deanmccall5023 I want to know as well. I want to be informing people correctly. Either way, the nose and sides are both 40 degrees. Do you grind down the top side at all? To 40degrees?

[@adgieem1]

You lost me at your loose wheel. Please Be more prepared when making a video ,

[@WilliamLancaster-tg1ze]

Sorry about the loose wheel. You must have found that annoying. You need not look at any of my other videos. I like to show Woodturning as it really is. Some of those flaws provide teaching moments.

[@lagswitch8525]

Yikes man you want a even bevel all the way around that think looks mangled

[@WilliamLancaster-tg1ze]

Stuart Batty and Ashley Harwood are the best proponents of the 40-40.
