Re: Great Dane excavating co.
So a rain day today, made a mock up of a haul truck tire.
   It's big!!! Way big!!! Actually it's about 1/2" too tall for actual scale. When I designed the part I added treds, should have designed different. But this is just a trial print and mock up to see how I can do it. And I figure this tread pattern is unidirectional and will allow for a simpler mould making extract. I have to print it in four pieces then they will be glued together and worked to be used for casting in rubber/ urethane. But it's scale for the size tires on a 785b haul truck. The biggest one I can make and still be able to load with the excavator.

Re: Great Dane excavating co.
I love it! I need to buy a printer BAD! I have be wanting to build a mold for a specific tire used on the off-highway logging trucks here many years ago. You have done yours exactly how I thought I would try if I had a printer(pieces). Since I don't have a printer I started to make my mold out of wood but it is very difficult because the grain messes with a guy while machining it. It sucks basically is what I'm saying. RW, you're my hero...

Re: Great Dane excavating co.
How much do you think the beast will weigh all assembled?
I have full confidence that you will succeed and make your own tires but I'm worried if they'll be strong enough to handle the load. Just like the 1:1 trucks. They say the only thing stopping them from making bigger trucks is the tires strength. Gotta find that sweet spot between too firm or too soft of a compound......  ok, I'll stop right there. My bad. LolAnd don't burn your shop down when you start cooking rubber!
