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.

@RonCovell Жыл бұрын

I thought of that. The small end of the cone is 1-inch, and the axle the cone rolls on is 1-inch, so I couldn't quite close up the small end of the cone unless I trimmed off a little material to make the cone shorter.

@lemontier Жыл бұрын

I thought that this video was outstanding. Forming cones that have a fit up flat and tight is tough. Tig welding an inconsistent joint on a cone is to me the maximum frustration with no way to avoid the roller coaster weld. Not to be able to get to the inside for raising the low areas makes it worse. The fixture that you demonstrated is really a work of art. Thank you

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.

@RonCovell Жыл бұрын

You are absolutely correct that each of the rollers rotates at a unique rate, determined by where it touches the cone. When I made the 'heavy metal cone' fixture, there is only one roller, so I know most of it was sliding, but it still seemed to work OK. The issue would be greater on a longer cone, and on one with larger size differences between the large and small end, but I still think that bending is a larger issue than sliding. kzfaq.info/get/bejne/o9OFmrdj2b7XoZs.html

I've been working in metal since childhood yet I always get to learn a new technique, pretty much every time I turn around. I've never had to make a cone, but that would've been helpful in making a few other sheet metal shapes. Most of my welding has been structural, but I've made a few fuel tanks and other types of tanks and I've seen some better methods than some I've stumbled through. Thanks Ron, always interesting!

@paulgerrity6077 2 ай бұрын

Very nice. I would add that I believe the many small rollers instead of one solid roller has more to do with the fact that they all need to spin at independent RPMs to properly track the sheet metal as the taper of the cone shape progresses.

While it certainly is an advantage to allow each roller to contact the surface of the sheet metal cone without slipping, note that you can actually make a nice cone even with considerable slipping: kzfaq.info/get/bejne/o9OFmrdj2b7XoZs.html

The pressure rollers are segmented because they have to roll at a different speed. When the mandrel turns half a rotation, the rollers at the large end have to roll a longer distance than at the smaller end. By segmenting the rollers they don't have to slide on the metal, causing extra effort to do the work.

@RonCovell Жыл бұрын

What you say is certainly true, but I build a cone roller without segmentation, and it works pretty well - even though there is a lot of slipping going on: kzfaq.info/get/bejne/o9OFmrdj2b7XoZs.html

@azyfloof Жыл бұрын

I'm guessing the gap in the final cone was because the paper template was a lot thinner than the sheet metal used for the cone, and you have to account for the material thickness. I'm surprised the machine didn't have a big wheel to grab hold of and crank it round :D I was waiting for you to bring in this giant wheel from off camera and slot it onto the end :P Excellent stuff as always, Ron!

@RonCovell Жыл бұрын

I think your idea about accounting for the metal thickness is right-on. I didn't think it would matter that much, but experience taught me I was wrong. Certainly a giant wheel could be used to turn the mandrel, but my half-inch 'breaker bar' worked just fine.

@azyfloof Жыл бұрын

@@RonCovell I also wonder if running the material back and forth a few times will stretch the metal out enough to close up the gap. Will likely work better with softer more malleable metals like copper and aluminium, not sure about steel though 😊

@RonCovell Жыл бұрын

From my experience with an English wheel, which is designed to stretch metal, I don't think Mike Cooper's tool develops enough pressure to stretch 34" of 16-gauge steel.

@1911wood Жыл бұрын

Your are correct. When calculating the blank size of a cylindrical/conical object you must use the outside circumference. In a previous life I used an Excel spreadsheet and later a parametric modeling program and a CNC machine to develop the flat pattern. The rolling machine Ron borrowed is nice for a pointy cone, open ( the frustrum of a ) cone can be made with a store bought sheet metal roller. I also added extra material that was marked by the NC machine to be trimmed away after rolling. This allowed us to have the finished edges to meet without any flat areas. We were rolling 1/8” aluminum.

@RonCovell Жыл бұрын

Adding extra metal to the edge of the blank, and trimming after rolling is an excellent solution to eliminating the flat spot!

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.

@edwardtaylor4785 Жыл бұрын

Nice project. I think, maybe, that the multiple small rollers are to better accommodate the difference in surface speed at the various diameters along the cone and, as you pointed out, a single roller would have to be pretty big to be stiff enough. A single roller would have to slip or skid someplace to deal with the different speed. Not sure if that would make. big difference, but it probably wouldn't make things better. Many shorter rollers reduces this problem. Very nice fixture BTW. Those first few cones were pretty expensive if they had to absorb the cost of the fixture. I get a lot of cones for exhaust systems from CONE engineering.

@RonCovell Жыл бұрын

Yes, there is no question that breaking the rolls into smaller segments reduces the 'sliding' a solid roller would have. I have made cones with a solid roller, so that issue is not a deal-breaker: kzfaq.info/get/bejne/o9OFmrdj2b7XoZs.html

Sounds like a cool project. I've found T0 aluminum rather difficult to source. It is not stocked by my local dealers, so I've had to special order it when needed.

Wondering if you could show how to build a cone shaped multi section 45" firepit cover? I'm thinking of using galvanized flashing with seams like hvac ducting.

@RonCovell Жыл бұрын

I think your idea could work well, and flashing is inexpensive, and easy to work with!

When you first showed the fixture I thought the setup was intended for the attachment of the leading edge of the sheemetal (not the middle). So that rotation was in one direction while slowly adding additional pressure every rotation , similar to sliproller.

@RonCovell Жыл бұрын

Well, you certainly could use this machine in a similar way, but that's not how Mike configured it. This video shows another approach with only two rollers, rather than the three on Mike's machine, and on a slip roll: kzfaq.info/get/bejne/o9OFmrdj2b7XoZs.html

Ron, I have a question that I think you could answer, and would make a great video. I want to make a set of fenders for my car, but what's a good method to get them to match other than just eyeballing it? I will probably make them from fiberglass or carbon, but ideally I just want to make one with clay on the car. Then I'd cast a mold and try to mirror it. How do you accurately mirror a metal fender, or part?

What do you think of having 3 tapered rollers, all in one, like a parallel roller, but all with the same taper, you may be able to direct roll sheet steel to form your taper.

@RonCovell Жыл бұрын

That would be the best way to go, and there are some specialized rollers made in that way: kzfaq.info/get/bejne/d6uJgtt1rJO4kZc.html

Ron great video. I noticed you did not show the transition when welding a long seam. Did you stop or was it continuous. I'd like a video on how to join long welds, with multiple methods if possible arc tig mig?

@RonCovell Жыл бұрын

It was a more-or-less continuous weld. I stopped a few times to re-position my body. Here's a video that addresses welding long seams in more detail: kzfaq.info/get/bejne/pLRpn7agvNubkps.html

Great video! I have a sheet metal question. I need to drill 54 1/2" ID holes along the long side (3/4") of a 1/2" x 3/4" x 36" piece of 1/16" thick aluminum angle. The centers of these holes need to be spaced 2/3" apart so there is a 1/6" wide space between their edges. Also the bottom edges of these holes need to be flush with the top of the short side (1/2") of the aluminum angle so there will be a 3/16 space between their tops and the edge of the aluminum angle. I only have a drill press to do this work. What is a good approach to accurately laying out and drilling these holes?

@RonCovell Жыл бұрын

Many approaches to this. Ideally, I'd use an annular cutter to make the holes (like a Rotabroach): kzfaq.info/get/bejne/h9Fxo7x40JjXgYk.html First, I'd lay out a centerline for all the holes, spaced 5/16" away from the corner of the angle.. I would do the layout on the OUTSIDE of the angle, so you will have to find a way to hold the angle upside down and horizontal in your drill press. A drill vise is a convenient way to do this. Next, I'd use a pair of dividers to lay out the hole centers along your layout line. Last, I'd centerpunch the center of each hole, and drill with the annular cutter. Easy peasy!

Hey maybe next time you might include spec’s on your tig setting’s. Other than that it was awesome. I’m not sure where to start. Thanks Ron Murphy

@RonCovell Жыл бұрын

I sometimes do include the welder settings in my videos, but I didn't this time. Here's a rough overview: DC, electrode negative, 65 amps, 3/32" 2% lanthanted tungsten sharpened to a sharp point, at about 45-degrees, with 15 CFH argon and no pulsing. Did I miss anything?

Love the clean workspace and precision of your work. I was wondering if a modified version of this could make different angle cones. A center threaded shaft and multiple threaded disks to allow you to vary the distance from large to small end of the cone.

@RonCovell Жыл бұрын

I have made SMALL conic sections using the technique you describe: kzfaq.info/get/bejne/g8eKkteV1ra2cYU.html I don't think it would be feasible for cone this long, especially with one end so small, but I've never experimented to find the limits.

Hi Ron, I’m in the woodworking trade myself, but I love metalworking for fun. I’m curious if there is a variety of sandpaper that you find best for this type of metal work? Not looking for brand names but abrasive type. I favour serated aluminum oxide for most of my work on bare wood and finishes for instance.

@RonCovell Жыл бұрын

I use aluminum oxide for most of my abrasives. I'm told that newer abrasives like 3M Trizact are superior (and considerably more expensive) but I haven't invested in them yet.
