I’m not aware of that product, I used a two part rubber https://www.ebay.co.uk/itm/266270964862 ... media=COPY
The pigment is added before mixing the two parts together. There are lots of colours, not that you want yellow or pink tyres .
I went for a hard compound due to the weight of the tank, 20kg is at the moment. I have fair bit of experience with silicone rubber making moulds for resin castings. But silicone would just be too soft. For this application.
I almost got 15 tyres from the quantity I bought. I did fluff up and mix two of the same part together so it never set.
There is always a little wastage too , I did not google too much so I did not find another supplier. Often materials like this are supplied in large quantities , not geared to the hobby user. I don’t like having too much rubber or resin stored not to be used for years.
I only had one mould, had I made t more than one I would not have mixed more than new tyres worth at a time due to the sort potlife.
Not sure how that urathane in a tube would cope with the UDT pattern on your Draggon Waggon tyres , excellent choice for a project, getting in and out of the various air pockets in the mould.
As mine is liquid , and a very simple shape. I am able to tilt my mould to get it flow and I suck the air out as I poor to help it flow.
It’s the experimenting with different materials I enjoy and if it’s economical to as well then that’s a double win. There is a lot of material in a standard sealant tube so very much worth trying out. If your tyres wear out quickly you can make spares cheaply.
I will soon start making the tracks. I am in two minds about the rubber track pads , I could not use my current method to cast the pads ,I could I suppose but it would be very tedious. I am minded to to cast the rubber onto the metal links direct. As I don’t know how attaching each one would be feasible.
The urathane you show may be the answer I have a method using something like that in my mind now.
I am already planning my next project A US T30, I would love a diamond T to haul her around with, so I would need a lot of tyres . Planning the next project before I have completed the current one is a bad habit of mine.
