The Riker previous owner told me the story of who took possession of the Riker from him, with the idea that he would be able to buy it back should that time ever come.  As the story goes, the next own

Hi there, finally I’ve managed to open my account on this page lol. Here are a few photos showing our Locomobile which will eventually become a double decker ww1 “battle bus”. Long way to go but

A few more photos of the Locomobile before we really make a start on her.👍

Ian,

I think you will find that the tires are actually polyurethane. This is usually supplied as a two part liquid that needs to be mixed together, de-gassed (bubbles removed in a vacuum chamber), and then poured into a mould. Most companies doing this sort of small numbers work make a very basic mould and then turn the required profile with a big lathe and a very sharp tool. Alternatively it is possible to make a mould out of, say, fibre glass which could enable an exact copy of an original tire, complete with writing, but of course the man hours add up then. Polyurethane is available in many different hardness's and toughness's and if you can get the right one it will far outlast natural rubber. this is what modern tank wheels are 'rubbered' with.

David,

Nice technology information on the evolution of hard rubber tires.  It almost makes one think that with some time and patience, you could pour your own "modern" hard rubber tires.

Nice projects for sure.  If I get to the point of hard rubber tires, I think I would give it a go and cast up my own tires.  I wonder what the pot life is and how viscus the material used for the tires is?  Can it just be poured or would it need to be forced?

Here’s a few photos of the Liberty rear wheels with her new tyres moulded on. Thanks for correcting me on the material , knew it was “poly” something lol!!!

So far so good 👍

Hello Ian,

Thanks so much for posting the pictures of your new "Liberty" truck tires.  You can see the way these tires were turned on a lath the shape the circumference and form the groove.  I am also interested in learning more about the source these "hard rubber" tires.  Did you only have new "rubber" put on the rear wheels?

It appears that the crsftsman, who did this project must have filled the form with water first in order to know just how much poly product was needed to fill the void.  I almost guess that the liquid Poly was poured into the mold in at least two places if not four with sprew ports in between to allow the air out.  I think I would like to give this process a try sometime!

Ian, Did you invest any time sanding out the lathe turning evidence, before you put the Liberty on the road? I am very impressed with the end result regarding your new rear wheels!

Here is a different approach on page 3. I was lucky some years ago to obtain vulcanised strips off a traction engine.

This forum is GREAT!  I have been given some terrific ideas on restoration of several items in my back yard, along with the dream of a Riker based around my engine.  I will post a picture of a 1910ish J. I. Case wagon wheel, part of an under carriage that I have, and make roadable wagon.  Sadly, as the picture depicts, it is currently on steel wheels.  This talk of Poly....tires has given me the idea that I could pour my own "hard rubber" update tires on these steel wheels and end up with a steel spoke J. I. Case wagon that I could tow down the road, (maybe with the Riker or one of my antique tractors).  The nice thing, the modern hard rubber tires would look the part as well as the simple steel wheels.  🙂

Here is a few more pictures of the Case wagon running gear.  It is these wheels that I want to try my hand at pouring my one rendition of a hard rubber tire using a Poly product.  the first three pictures show the steel spoke wheels.  The last two pictures tell another story.  I am missing one of the original cast iron hub caps.  I decided to send one cap off and get a set of bronze caps that I can polish and make the gear a bit more showy.  One cap is the original cast iron cap the second is one of the new Bronze caps, (still need to be machined to fit).  Maybe someday the future Riker project can pull this Case wagon dressed as a Military supply wagon in our local parades.

Ian, 

Have you learned what the name or the polyurethane product was used for making your rear tires?  I have done some scouting around, (and found several possibilities),  but would like to find a more affordable source for the Poly material..

Nice Peugeot... What is the current status of the truck?  Your picture is about 10 years old.  I really like your cast spoke wheels!

Al.

If you look into the thread, you'll see the current status of the Peugeot on the last page. On page 3 and 4 there are some pictures of what we did with the front wheels. It is not quite finished yet, but running good.

Hello Cel,

What is the name of your forum Peugeot thread?  I would certainly like to read about your project and see the current status.  I am still not the best with migrating around in this HMVF, but I am getting better!!!!
