As you may know for my current project I am building a 1/16 scale farm tractor. I needed tires for it a devised a simple way to make em, considering I didn't have anything besides fairly conventional tools.
I started by measuring the tires on a 1/16 scale tractor then transferring those measurements to several pieces of walnut. The walnut varied in thickness depending on the size of tire. Here, walnut resawn to 3/8 is drilled with an 1-5/8" forstner bit then cut on a band saw.
I screwed the halves together and sanded them even, marked them, then took them apart.
Using a round file, I began to file at a slight angle off from 90-degrees at predetermined points. Then, on what was deemed to be the "outside" of the tire, I rounded down the valleys to give the tread bars a more raised look. Notice the notches at the top and right side of the tire have been rounded off, the others have not yet.
The two halves are rejoined with woodglue, slightly offset to give the distinct bar tread pattern. After a brief final sand, I'm ready to mount onto an axle!
So there is how I spend my days off from the fire department, gentlemen! ...doing tedious, intricate work is something I crave!
Hope you enjoyed this brief glimpse at my process! More pictures will arrive soon!
