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.

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.

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!

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.

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.

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
@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. kzbin.info/www/bejne/o564mIdoqb2mp8k

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: kzbin.info/www/bejne/o564mIdoqb2mp8k

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.

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.

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.

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: kzbin.info/www/bejne/o564mIdoqb2mp8k

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
@RonCovell Жыл бұрын
Many approaches to this. Ideally, I'd use an annular cutter to make the holes (like a Rotabroach): kzbin.info/www/bejne/h5ykoYx9oJemh7c 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!

I made a flattened cone using the card stock layout method to form it from 16 gauge aluminum. T0 aluminum so it was like butter.

Any idea how long it took to make that fixture? Even with a water jet to cut all those ribs it seems like it'd be a solid week of work just for the structure, plus time on the lathe to cut that taper.
@RonCovell
@RonCovell Жыл бұрын
I didn't ask Mike how long he spent building that fixture. I know it would take me at least a week - probably longer. My little 1/2-horsepower lathe would really struggle turning a cone the size of that mandrel. Fortunately, Mike has a couple of pretty serious lathes.

Heck no! That's a very expensive chunk of aluminum to start with, and it takes many, many hours to machine an aluminum cylinder into a cone shape. Who would want to throw away that much time and effort?

Hi Ron How did you prevent the weld from shrinking and turning it into a cone shaped banana..did you work the weld after welding I have done similar jobs in the past in steel and stainless ..had problems with the dreaded banana Cheers mate love your work
@RonCovell
@RonCovell Жыл бұрын
I've made quite a few cones, and none of them have curved like a banana. I can see how this could be a possibility, particularly with stainless. I didn't stretch the weld by hammering after it cooled, but that would be way to correct any distortion if it did happen. I think the smaller the diameter of the cone, and the smaller the taper, the more of a problem 'bananaization' would be.

Mike told me that he made many passes. I figured that it takes a certain amount of torque to start the metal bending, and it's probably better to just keep going, rather than to make many passes at different 'depths'. Seems like it worked fine.

@pmcquay1

Correct me if I'm wrong but I don't think there would be a flat spot on this one, because the mandrel is always supporting the material against the smaller rollers, as opposed to a traditional rolling machine where the rollers are not the same size as the finished part, and it relies on having 3 points of contact to do the bending, so at some point you get the end of the material passing one of the outside rollers and the distance between that roller and the middle one becomes your flat spot. You lose adjustability with this method though, you have to have a mandrel for every size of part you want to make.
@RonCovell
@RonCovell Жыл бұрын
Thanks for chiming in on this. It's true that the flat spot would be smaller on this fixture than on a traditional slip roll, but Mike Cooper (the fellow who made the fixture) told me that he got flat spots, so I thought I'd take steps to alleviate the issue. You are absolutely right that this design is locked in for one taper, although you could use selected sections of the fixture to make cones of different sizes, as long as the taper was the same.

It's pretty challenging to make a 180-degree dome from a flat piece of metal. One of the issues is that the center tends to get too thin.

No plans are available, but it shouldn't be too hard to make a similar machine. None of the dimensions are critical - except the diameter and taper of the mandrel. As I said near the end of the video, I believe the mandrel could have been made from hardwood - which is much cheaper, and easier to turn.
