  • 3D printed track for Pershing and "EZ8" Sherman tanks

    Started a little side project to create some T84 chevron track pads to replace my worn out nylon Tamiya track pads since Tamiya has discontinued making new tracks for the Pershing/Sherman. The T84 pads are those seen on the "FURY" movie Sherman but were more commonly used on the Pershing tanks of the 1950s.

    What started out as simply creating pads turned into much much more. During testing the prototype T84 pads worked so well I decided to take the next step and make center guides and then they worked out well. Dare I attempt end link connectors...you bet and after a few tries darn it got those to work well.

    So now I have all the working components and just need to print them. Well I dove in and had the all the parts printed on mass. JVM3Dconcepts did the printing and suggested I make the "production" parts out of a high strength engineering resin which I did.

    After I received all the parts I though "What did I do, this is going to be a lot of work". A complete set of dual pin Pershing tracks consists of 1148 (+ - 2) individual parts and I still needed to dismantle my Tamiya Pershing tracks so I could reuse the metal track pins, that's means dismantling another 1148 individual parts. I will be moving around 2300 parts to make one set of tracks!! OK that sound like a lot of work but it actually was very easy and took less time then I expected.

    I will not bore you with the assembly photos so here are the test run photos conducted on my Tamiya Sherman and the end photos of the tracks on my Pershing. It should be noted that these tracks work on Heng Long Pershing tanks as well.

    If you have any questions feel free to ask. You can also view some of the video testing I did on my Instagram @ fsttanks

    Final fully assembled tracks on Pershing. These tracks only use metal pins the rest of the track is all 3D printed. The white "scratches" on the pads is normally to see on black plastic as it starts the wear in process. It will soon take on the correct weathered and worn look of real rubber pads used on tanks.Click image for larger version  Name:	13E00ADC-7BCD-4481-9898-B52581AC8597.jpg Views:	0 Size:	319.6 KB ID:	373151Click image for larger version  Name:	81FEF0B4-6197-4DE3-90FD-7C93CC0E5AC5.jpg Views:	0 Size:	309.7 KB ID:	373152Click image for larger version  Name:	134D26B7-40A9-479C-B4C2-3AD2EA895BB0.jpg Views:	0 Size:	170.5 KB ID:	373153

      Looks like they are working out well. I'd guess they're robust being engineering resin and your use. Were they at least a mindless assembly of parts so you could sit and watch Fury while doing so? Weathering tracks I enjoy. I'm not sure how much I'd enjoy assembling them with that many parts though.

      Great work.

        Great work.
        The tracks are far more robust and functional (smoother running) then the stock HL plastic or Tamiya nylon tracks they replaced, but not quite as robust as metal tracks. They are providing a viable option for something between plastic and metal where the correct look is desired even after/when the paint/weathering wears off with use (not like the current T84 chevron pads that end up as shiny steel).

        Assembling them was actually not to mindless of work. It actually was a bit fun once they started taking shape. But it's not something I want to do every weekend though.

        I am working on another more commonly used track pad replacement for the HL and Taigen/Torro Shermans that will replace the incorrect steel metal chevron pads used on Taiagn and HL tracks. This will more correctly represent the actual rubber of the chevron as the track wear. No more shiny steel "rubber" chevron. Those should be up for testing soon and I suspect they will be just as good or even better then my T84 tracks.
