It hit me - the reason you seem so good at everything you do is that you're willing to experiment and learn and try again, and very quickly learn from those mistakes. Thats a great skill to have.

It's such a pleasure to see the videos of a gentleman! Many thanks to you!

What a scandal it would be if someday we found out that just outside the camera view of Ron's admirably clean workspace there were hoarded stacks of newspapers, piles of laundry on the floor, and teetering piles of tools and scraps.

You have great mentorship skills! Thanks for a very informative and pleasant learning experience!

Thanks for the video, you are in deed a great master in metal forming and workshop technics.

[metalworkingdude]

Wow, great video. Love that fixture too! I remember when I first saw you forming cones out of 1/8” plate and using those cones to build stunning suspension uprights. That was a life changing experience.

Thank you for sharing your expertise in your videos, super interesting and very didactic, cant wait to experiment myself!!! Your channel is amazing! Greetings from Mexico

Mater Ron, how educative insight into the preparation and a nice recovery for the undercut 👍always a chance to learn something useful, as always

That green brake is a gorgeous machine.

Impressively accurate for such long skinny cone dimensions. Very nice. Great finishing job too.

For a wooden mandrel, I might worry about shape stability long-term as the wood slightly swells and shrinks due to changing humidity. Then again I've never made anything from wood that required tight tolerances so maybe I'm overthinking it.

Hi Ron.

Fixtures are king.
I like to design odd stuff just so I can make a new tool or fixture.
Another project done well.

Wonderful art, and homemade cone machine. Great video Ron.

Beautiful work and presentation. I made a cone for my project just yesterday but mine is certainly crude compared to yours. Nevertheless, my cone is satisfactory for its purpose: it stands on a gas stove burner and is used to radiate heat into a small space. I did the math to make my pattern then placed it on a section of used black stove pipe to mark the cuts. I cut it out with a plasma cutter then rolled it into a cone shape by hand. Mine is riveted together. I like your idea of making a mandrel from hard wood - I will try that next time to get more control on the final shape.

nice work Ron, i watched this this video because im involved with high quality double lock standing seam roofing, therefore i have to learn to fabricate waste stack vent pipe that wont leak from 26g painted steel. ive learned some techniques but id love to make a tool that would make some of it easier...

I remember Mike being featured in your How To Work With Tubing video. The things that go through his mind when he creates his sculptures! Almost as much work building the fixtures and tools as the actual sculptures themselves.

[willclark]

What a fantastic fixture! As usual, you give a super-clear explanation of each part of the process, and leave me with the (false) impression that I could do it too. 😁

[stewartmcneill]

Hi Ron thanks again for your skill and knowledge your the craftsman

[billdlv]

Nice work Ron👍 Your friend Mike is very talented

[shinergriff]

Hi Ron, I appreciate all you do it's very interesting to learn form a skilled man such as your self.
On the cone rolling fixture you spoke about the many rollers rather than the singular one you mentioned that it was the rigidity was needed you were of course correct, also I might add that the distance each roller must travel per revolution of the mandrel would also be a factor.

Good afternoon, Ron! I thoroughly enjoyed the video as always. That is a very thoughtfully designed fixture Mr. Cooper built with all the supports and the series of small rollers. I wouldn't have thought of that and as a result would have ended up with lots of flex as you described. I appreciate you taking the time to share the process with us and even more so for showing your solutions to the minor problems you encountered along the way. Using the simple hose clamps was brilliant and worked like a champ.👌 Cheers, buddy. I hope you enjoy the rest of your weekend.
