Looking into making a corrugating tool for HO

    Mine is HO scale. I made the thing to make my own because I ran out of the Campbell's corrugated aluminum. I think I rather buy theirs than make my own because the stuff they sell is reasonably priced and looks great. The stuff I made looks ok, but not as good as I would have liked.

      Dave,

      It's not supposed to look good. But you solved a problem in excellent shape. [:thumbu] (still missing)

        That little house looks pretty neat. Love the satellite dish and TV antenna.

            how bout cutting a profile on a pc of aluminum or steel and putting in a small press instead of rolling it

              I just have this affinity for wanting to roll it. Don't know why, can't explain it.

              I see a cutter would need to be fabricated. I think that would be a little harder than grinding a piece of tool steel like one would use to cut threads with. Then use a CNC machine to profile the round part. I have it all sorted out in my mind how to go about it and will write up a complete report here when I get into it. I want to try and see if I can turn my Sherline mill into a lathe to cut the round part. If this project fails then it'll be on to making a press.

              Thanks for the input, Joe. Never know what somebody else might come up with when suggestions are put forth like this.

                Bernd:
                I see you are building a metal building on another thread, sense the building is made of real corrugated metal, couldn't you use two pieces of that material as a press?
                Just a thought?

                  Good point. I took a closer look at the ends of the metal corrugations. It really doesn't look like a corrugation. It looks more like it was run through a set of rollers that produced a crinkled effect. You might be able to get some formation by pressing but I don't think it would give good results. I'll give it a try and report back in a few.

                    Ok T.C. I've got the results. Doesn't look good. I rubbed it with a piece of insulation foam. All it did was make the depression for the chimney hole. I also tried a piece of wood. Didn't work. A piece of softwood, didn't work and a blunt rounded end on individual valleys. Takes way to long plus there is a possibility of tearing. The aluminum foil measure .004" thick, that's .1016mm for you metric people.

                    Looks like I'll need to make the rollers.

                      Did you try other thicknesses of foil?

                      Thursday, I was thinking of this project, while I wrapped the turkey in "heavy" baking foil. It was less thick than what you tried to use. Wondering if the foil used was ultimately too stiff for what you were trying to accomplish. Heavy duty foil measured 0.02 mm, compared to your 0.1016 foil. Yours was five times thicker in comparison.

                      Before concluding the process is not working, try something thinner from the supermarket,, that isn't the thickness of an aluminum pan.

                      Maybe dragging a stiff long bristled brush across it would give you more ability to follow the underlying surface, with less risk of tearing it up..

                          Thanks T.C.

                          It's not turning out so bad at all. There have been many ideas and solution put forth. Now when somebody asks how to do their own corrugated metal there is a collection of ideas that have been tried that show the results.

                            Ok Dave, here's the tinfoil hat...........er I mean tinfoil corrugation test using both heavy duty tinfoil and standard tinfoil. First I measured both. Believe it or not they both measured .001" or .025mm thick. Anybody care to coberate those dimensions or are we talking about splitting hairs here?

                            Here's the results in picture form. The tinfoil containing the red and blue circles is regular tinfoil. The tinfoil containing the green circle is the heavy-duty tinfoil.

                            The red circle I did with just running my finger over the foil. The blue circle is done with the nylon bristled brush as is the heavy-duty tinfoil with the green circle.

                            I might mention I had to position the foil to get the light on it right so you can see the corrugation. I think if you gave it a weathering coat it might fill in the valleys and you'll never see the corrugations. To me this material is to thin for its intended purpose. I think even in handling to cut it into sheets you'll lose the corrugations. I'll continue with the roller idea.

                            Anybody else have any ideas, add to the thread. The more info the better.
