Never have understood how to use the set up block until now. THANK YOU so much.
This setup block works perfectly. Great job Ron
Sold! Just bought mine. Thanks for the video!
Nicely done. Good instructions. Easy to understand. Thanks
Glad it was helpful!
Thanks for sharing this very informative video 🙏🏼
Just bought one. Excited to try it out. Very reasonable price too
Well Ron I have to say this is the very best explanation on how to use a specific setup on any sort of grinding accessory.
I have been using the 40/40 grind for awhile and have ground it free hand. I certainly want to try your method because it looks to grind everything just right.
Very early this year Stuart was in town and I went to the all day demo. He has the grind down but has done it countless times.
I do a lot of wood turning and I certainly am interested in you setup.
Thanks for posting this.
Take care,
Gary
Thanks for your kind words. You asked if you could contact me. Yes, the office phone is (770) 962-3821 Eastern time zone. The website is www.ronbrownsbest.com.
Thanks Ron I will think about how bad I need this before buying one. I know I am sure interested in seeing for myself how it works.
I did not notice what it was made of either.
Thanks again.
Great video instruction~! I'm completely new to grinding, so this was very informative and helpful in demystifying this task. Heading to your website for more info~! Thanks much~!
@TEXT ME ON TELEGRAM AT hello catwalk city Hi Ron~! I'm looking into what "Telegram" is and I will reach out to you, unless there's another method of contacting you. And thanks for the notification~!!
Thanks Ron
Great video, Ron. Question: anyway to make this work with the
Varigrind 2?
Hi Ron, Interesting video and great explanation. Just wondered with your experience would you have any suggestions for using the Sorby pro edge for the 40/40 grind?
Although I have that machine, I have not tried to figure out how the 4040 Grind Set Up Block might be used with it.
Ron
Great jig. I’m having trouble getting flat or convex wings. Does it matter if I’m using a U shaped gouge? Everything else is working well, Im just getting concave wings. Do I need to turn the verigrind jig past 90 degrees or try to keep it at 90?
Please take a look at this short video ua-cam.com/video/2DF_VY2Ccwo/v-deo.html it should help a lot.
Ron
Hi Ron. Did you mean I won a prize? Still loving your jigs and have to several about you.
Thanks,
Steve Payne
Hey Ron Hope you are staying cool!!
Not at chance. Dehydration is the biggest problem. Blood pressure down lately.
Thanks for reaching out.
What material did you use for your setup block? It looked very sturdy.
I use an almost indestructible HDPE 1/2" thick. You could run over these with an 18 wheeler and have absolutely no effect.
Ron
The video shows you using a Wolverine system, and set the varigrind on step #1. If you were to use the Pro Grind system by Savannah would you also use step#1? Any other differences between the two? Thank you.
Dear H, The leg on any gouge holding fixture should be pulled all the way up as far as it will go. It doesn't matter if it is a VariGrind 1 or 2, the ProGrind, the SharpFast, etc. You would use a 3" projection on all gouge holding fixtures also.
Hello Ron, Keep water nearby to cool the blade if it gets too hot? I read an article in a woodturning magazine years ago which discouraged dipping hot high speed tool blades into water as this would degrade the molecular structure of the metal, causing microscopic cracks throughout the tip. Roll on 15 years 'ish, does it no longer matter? I have always laid my tool on my cast iron bandsaw table T slot and placed a heavy metal object on top of it ( a hammer ) to radiate the heat from the blade, a kind of heatsink. Do you have any thoughts on this matter. Best regards,and keep well.
They could be correct. I don't get the edge very hot before I cool it down. My M2HSS tools hold an edge plenty long enough to satisfy me. I am not disputing what they say. I just pass along what works for me. You decide for yourself. Buy an inexpensive tool and put an edge on it. See if cooling it with water makes a difference.
@@Ronbrownsbest Ok Ron, I hear you. Thanks for the reply.
Nice addition to tools. Have you ever considered making tools and gages for 6" grinder wheels? I can't be the ONLY turner with 6" wheels.
Mark: I have my regular set up blocks and the Quad Setting gauge available for 6" wheels. The demand for 6" grinding wheels is far too low to design everything for 8 & 6 both. You can't imagine the amount of design time and testing required to get things right. Also, I don't have a Wolverine system set up on a 6" grinder. I have 3 8" setups but no 6".
Ron
@@natraz823 NOT THE SAME! this setup block is calibrated for an 8" wheel. I have no idea what you will get with a 6" grinder.
I have your other set up gages and blocks, is this available separately? Cheers, Tom
Tom, it is a stand alone product that we just released 03-21-2020. You can learn more about it at www.ronbrownsbest.com.
Ron
Ron Brown Thanks Ron. Cheers, Tom
I would like to purchase your set up system for this 40/40 grind.
I use a 6" grinder.
Will it work with this size wheel?
Thanks for any feedback.
This has been calibrated for 8" wheels only.
Ron
Hello Ron - I have a Varigrind 2 (instead of 1). Would this jig still be compatible?
Thanks sir
If the geometry is the same it should work. Any other comments?
@@mikebulat ok. Is the geometry the same ?
I put the arm in the same position {angle} then used Rons gauge for distance of the VII cradle and was able to duplicate the grind.
@@mikebulat Awesome thank you very much. Ron expect a purchase soon sir.
kliddiard Just make sure the arm is at the same angle that it would be if using the Varigrind one, because the Varigrind II arm will not be all the way up like the varigrind one.
Ron, will this set up block work with a grinder with 10" diameter wheels?
This setup is calibrated for 8" wheels only. Sorry.
Ron: I am interested in this jig but only have a Varigrind 2. Have you tested it with that version?
I don't have a varigrind 2, so I have not tested it myself. I have not heard from any customers with the 2 yet either. This was an extremely difficult block to get right. The combination of leg angle and stick out took forever to figure out. It works magnificently with the VariGrind 1 using the recommended settings.
@@Ronbrownsbest Thanks, Ron. I ordered it this morning, since I'm borrowing a neighbor's VG1!
Have you considered a modification of your current jig to allow it to work with the Kodiak sharpening system by WoodTurnersWonders?
My 4040 Set Up Block already works with all of those systems. The Kodiak system is a private label of the Sharp Fast System. The tool holding fixture is almost identical to the VariGrind 2. The 40/40 will work perfectly with all of them. Pull the round bar all the way up, use a 3" projection specified, and make two firm points of contact.

@@Ronbrownsbest Thanks for the clarification.
This setup block is available at www.ronbrownsbest.com or directly here www.ronbrownsbest.com/index.php?route=product/product&path=20&product_id=737
Where can I buy one of these setup blocks?
You can get them at www.ronbrownsbest.com. They now include the riser block so you don't have to grind the pocket arm. These are calibrated for 8" grinding wheels.

Shouldn't cool HSS with water. HSS doesn't lose its temper when overheated, but when quenched gets brittle!
True at very high temps. You should never let your turning tool get up to that high temp before cooling off. Hot to the touch, but cool on a relative scale will have no effect whatsoever. Keep the tool cool enough to handle and you will be fine.
Are you connected with the comment to me below? Looks like your picture but does not seem like your UA-cam channel.

Ron,
Just a quick note to let you what I think of your new 40 40 grind setup jig.
IT IS GREAT!
It does exactly what you say it does, it is easy to use (if you follow directions), it is repeatable, and IT WORKS!
I reground one of my older 5/8 bowl gouges and then took it to a machinist/engineering friend. He inspected and measured it thoroughly. His verdict: 40 degrees on the nose AND on the wings with a single facet.
Once again you have a winner!

Like the jigs and I've bought them all. I hate the piano music.
We appreciate the feedback!
Overly complicated! But hey, nice “custom” gage that we all need to build or buy (where)? Doug Thompson makes it much easier.
I must be an idiot, but it appears there are an infinite number of ways to get a 40/40 grind, and I don’t understand any of them, including this video.
Sam Angelo just posted a new video and does a very good job of explaining the 4040 grind. ua-cam.com/video/op3XPi9ZobI/v-deo.html. Also Stuart Batty has a good video on his method.
@@Ronbrownsbest Well, I bought your setup block, Ron. Wish me luck!
