Making a tire from scratch

[Tage]

Very nice, thanks Bill

What material did you use to cast them? Liquid plastic or rubber?

I need to do something like this on my truck model. I only have 11 tires to make though :)

That works for me. Great tutorial. This is definitely one I need to commit to memory.

Thanks Daniel, Mike, and Jeff.

Mike I use a polyurethane rubber, it's distributed by BJB Enterprises, Inc. It's a 42 durometer, fairly soft but they make
other hardnesses. They have a nice variety of resins. I buy most of my resins from them!

And thanks to whoever moved my post to the right place, I must of hit the wrong button.

Ahhh...cool. I think that is the same stuff that I used to make my last tires.

Did you make these as a hollow tire? I take it you probably used some sort of foam insert to fill the void if you didn't pour them solid?

If you have any pictures of the mold making and pouring the tire, I would be interested in seeing them too. Like I said....this is right up my alley on what I need to do. The last tires I did, I poured them as solid rubber. I'd like to get away from doing that this time just to save some material.

Sure Mike I have a tutorial on molding and casting , I'll post it in the next day or two.

Thanks Bill for making the next tutorial. That's the part I'm totally unfamiliar with.

A tip that I saw years ago to create the tread for the tire was to get the artwork Photo etched in thin brass cut half way through rap that around the tire buck then stack another layer of PE of thicker material using the same artwork cut all the way through.

I have a hobbiest CNC machine I want to try your technique and cut the threads on the CNC from sheet stock.

Hi Vince, the photo etch process would work, but you would have difficult time sanding the the brass to get a nice smooth
surface on the tire.

The CNC would be the way to go.

Hi Bill,That is outstanding work! So you cut all those tiny tread patter bits by hand? That would really test my patience. :-) I need to look at this rubber you use. I always wondered how I could make a realistic tire.Thank you so much for posting.Manfred

Hi Bill, Thank you very much for this fantastic tutorial! I'm sort of stuck with my current project (an 1/16 M923) because of the tires. A lot of fresh ideas here. Great! Hans

nice work on tire, what metal type did you use to cut side profile of tire?

[bills69camaro]

I used a inexpensive metal I bought at a Home Depot.

regular steel plate they sell?
