    1/14th scale Bulldozer tread links. I'm guessing they are diecast, but the description says no.

    I am guessing not easily. Start with custom extrusion.

      The vertical mounting flanges appear to bolt on. That makes it a 3 piece assembly. The larger flat section could be made in a longer strip and saw off each one. The small flanges made in a sheet using tabs to hold them, a bunch at a time. Things like this are where a cnc mill and fusion shine !!

        I'm just talking out of my ass but using the equipment I have at hand....

        I think I'd weld it and make it in two parts, from the pics it looks to be two parts bolted together. Use several plates to make the bigger profile and then machine the welded piece. Same procedure for the 2nd part, weld up a U-profile I guess and machine the features onto it, then bolt them together.

            For once in the past couple of years I want something to be made out of metal

              Sand cast them out of aluminum, not hard, look ugly “Backyard Metal Casting”!

                I was going to suggest the same thing. Good excuse to build a foundry.

                You've already got the 3d printer to help make patterns. It's a natural progression......

                  I knew a fella that used to build some incredible all metal scale model bulldozers and I remember that he built his track pads and links by fabricating them from mild steel plates that he welded and ground in a jig that he built for the purpose, very time consuming but they did come out very nice.

                  I do know that 1/14 scale pads are now available commercially as linked to below, but I'm sure that's not the answer you are looking for.

                    Just program it into your CNC machine, and it should spit it out, right???

                      Doozer bet me to it. It's obvious, CNC man!

                        They said it wasn't die casting, but that doesn't rule out investment casting. Investment can be near-net sizes and incredibly detailed. I would use either 3D printing or machinable wax to make the negatives.

                          You just need a new printer that prints metal Tom Lipton had a piece printed out of metal a while back. Wasn't super expensive. I think he said you pay by the amount of material as complexity doesn't matter for the printer.

                            Here is the video. It was $78 for the part.

                              Have it printed in metal
