Hi:

Reading the post and replies on the impressive -once more!- White 920 build  by Neil Craig I recalled an old SBS I posted on FB a couple of years ago on the topic of making simple treads on road wheels.

Here we go with some basic in detail wheels

We can see that basic tyre tread detail is raised while it should be engraved.

The challenge here is to have five grooves as tyre tread and a  must have is to have them paralell and evenly spaced too.

There you go the required tools for this task. A sharp and thin p.e. saw seems obvious. But, trust me, the critical key tool is the post-it block.

You may not notice it yet, but this is the basic principle. Combining the saw and the post-it block will give us a pararell cut to the workbench flat surface.

Just stacking more or less post-it notes we can determine the exact height for any of those tyre tread channels.

It´s easy and rather precise!

Notice you that placing the saw forward / backwards into the post-it block...

...we can control how much depth our channel is going to be with some good precission.

Once we have decided the saw potition and height for the first groove we are good to go.

So simple!

Once we are done with the first groove, just add as much post-it notes you may need to raise the saw to the next cutting position.

Here we go again... place the p.e. saw...

Ready for the second groove...

Rinse and repeat!

And this is the final product.
