Putting a radius on a grinding wheel with our Yuasa Radius and Angle Dresser. Link to Stan's video for a more detailed setup: • Yuasa radius and tange...
Nice work ! Reminds me of my days as a die maker grinding carbide punches and sections on a Reid Surface grinder. The punches and sections were for 4 and 5 Station progressive lamination stamping dies. This was in the late 60's to early 70's . I was 23 yrs old. Just finished my apprenticeship!!! I was on top of the world as a journeymen die maker.
A really informative video, but aren't they all. You cost me money every time I watch one of your creations. I end up looking for whatever interesting tools you are demonstrating. Great job Steve.
@@SolidRockMachineShopInc I purchased a DoAll 6×12 manual machine ($155) and a Gallmeyer& Livingston #45 12x24 hydraulic machine ($55) Both have mag chucks and coolant systems. At the same online auction I also purchased 2 radius dressers and lots of magnetic transfer blocks, extra wheels , small vises and compound sine plate. I need to watch more of your videos to get a glimpse of your DRO setup. Thanks for sharing all of your knowlege!!!
Man, you have some cool stuff! So many things one can do with a surface grinder, hoping someday to find a used one that isn't too beaten. Thanks for showing this, I wasn't aware you could "form tool cut" a groove with a surface grinder.
As Colonel Sanders would say, finger licking good... Nice info and demo of what you are doing. Stan's video was nice showing the setup steps. Looking forward to your next video.
Hi Steve, now that you have your wheel dresser, it is nice to know the distance from the centerline of swing, to the edge of the base that goes against the grinder back rail. That way if you have to grind a radius larger than the width of the wheel, you can use your digital readouts, and a little math, to reposition the wheel for a new segment of the radius, and positioning the wheel to the work piece to blend in with the previous wheel path. Gooday!
Another fine vidio packed with nuggets of information. Like your new radius dresser, relatively easy to use... After being shown how by an expert..! I wonder the likelihood of picking this up as a bargain in Oz.. Haaaa. See you next vidio. Carl from Oz.
It is based upon the distance of the diamond tip to the center line of the swing of the radius dresser. Convex and concave are determined by which side of center line (above or below) you are on.
I don't think you mentioned it on the video, but how did you position the dresser so that the diamond was positioned inline with the lowest point of the wheel?
You turn the dresser at 90 degrees and take a light cut on the wheel side, zero the DRO and do the same to the other side of the wheel and read the number on the DRO. Then divide the DRO number by 2 and move that amount to the center of the wheel.
@@SolidRockMachineShopInc I don't mean centering on the sides, i mean centering on the tangent of the wheel, so that the radius you dress doesn't end up being an ellipse on the wheel.
@@sccolbert I am not sure I am following you. You can rotate the dresser at 90 degrees and line the diamond up to the dresser center line master so that the diamond tip is located true to the dresser center line. I don't know if this is what you are asking.
@@SolidRockMachineShopInc Man, this is hard to describe. So, the axis of the surface grinder that runs on the ball bearings and that runs parallel to the face of the grinding wheel (the primary "back and forth" axis) . You have that axis locked down for dressing. How do you position the dresser along that axis so that the diamond is dead inline with the bottom of the wheel? If I am thinking correctly, if the diamond is not dead-on inline with the bottom of the wheel, the profile it will impart to the wheel will be an ellipse instead of a true circle.
@@sccolbert Now I understand. The way I find center is eyeball center of wheel snug the table down then traverse in Z axis to dress the wheel. then move in the X axis slightly and traverse in the Z again. if you hear contact you keep moving slightly in the same diction until you no longer hear it then move back slightly to center line of the wheel. you can repeat a few times to get almost perfect on center.
It depends on the diamond tool and how deep the radius. If my memory is correct I believe I dressed a small as a .06" concave radius in the past. You can go much smaller doing a convex radius Steve
A machinist with a US GENERAL tool box?? Blasphemy!! Lol nah just joking. How has it held up? Debating buying one myself. Not a fan of the brown Kennedy. Great video by the way.
I have many older Kennedy boxes and like them. I hear the new one are not as well made. That US General is a very nice box too. I only have the one and no regrets buying it. The drawer selection is perfect for our use. I would not hesitate to get another one if needed. Steve
Every video you post is a goldmine of knowledge. Thanks
Thanks for the kind comment and you're welcome.

Looking forward to the video on the CBN wheel. Thanks for posting!
It should be the next video.
Steve
I purchased 2 surface grinders last week. I'm so glad I found your channel!!!
Awesome! Hope you find our videos useful!
Hi Andrew,
What kind did you get?

Wow! looks like you had a great auction. The mag chucks alone are worth way more that that.
Steve
I always enjoy seeing the fancy grinding setups. :-)
Thanks for watching Brian.
Steve
bcbloc02 - Isn't that when I'm holding the angle grinder with both hands?
Thanks for the great lesson Steve. I learn new techniques in every one of your videos.
You're welcome Eric.

craftmanship + quality !
Thanks Claes.

Morning Steve, Another great video of machinists know how
Thanks Warren.
Steve
Enjoyed Steve, good stuff!
ATB, Robin
Thanks Robin.
Steve
Great work nice lesson on the diamond dresser.
Thank you Steve you are joy to watch and share in the comments here.
Lance & Patrick.
You're welcome Lance & Patrick.
Steve
Very interesting content,thanks Steve and Kathy.
You're welcome B Clare.
Steve
Thank you!
As Colonel Sanders would say, finger licking good...
Nice info and demo of what you are doing. Stan's video was nice showing the setup steps. Looking forward to your next video.
Thanks Ryan.
Steve
Well done on the radius, nice to see how you'll prep the CBN wheel... 😎👍
Hi Pierre,
Hopefully that will be the next video.
Steve
I really appreciate your tutorial. Great job.
You are welcome!
What a score on that dresser....they are almost $2K new....
I Know. I was happy to get it at the price we paid.

Good lesson, discussion/demonstration...thanks for sharing your knowledge and time
You're welcome Chuck.

Another fine vidio packed with nuggets of information.
Like your new radius dresser, relatively easy to use...
After being shown how by an expert..!
I wonder the likelihood of picking this up as a bargain in Oz.. Haaaa.
See you next vidio.

Thanks Carl.
Steve
Very nice job. Great instruction and demo. enjoyed. Thanks guys.
Thanks Randy.
Steve
Very nice video! I was able to find the dressing stick by searching for Boron Nitride Dressing Stick
I believe Mine came from MSC.
Steve
Another great video,thanks.
Thanks sound limit.
Steve
Nice tool. Thanks for the video.
You're welcome Harold.
Steve
Nice radius dresser . Cheers .
More great lessons ! Thanks !
Thanks Brian.
Steve
Used a similar radius dresser for many years
Hi Eddie,
I used a number of different styles in the past and this style is my favorite.
Steve
great video
Thanks Sandia.
Steve
👍
Watching in Alabama
Thanks for watching Anthony.
Steve
Thanks for sharing
Thanks for watching!
Steve
👍thanks for sharing more of vast toolmaker's skills!
Rather like the dark finishes from heat treat to add contrast and make the grind stand out more.
You're welcome James.

May I know sir the formula on how to set the dresser to a convex and concave.
It is based upon the distance of the diamond tip to the center line of the swing of the radius dresser. Convex and concave are determined by which side of center line (above or below) you are on.
I don't think you mentioned it on the video, but how did you position the dresser so that the diamond was positioned inline with the lowest point of the wheel?

What's the smallest radius this tool can profile?

Sir one video angular surface grinding and use for sin cos calculation new video send for CZcams
