Hello From Oregon

[Wrekage]

Hi all,
I was very happy to find this forum. I am new to the hobby but have a passion for heavy equipment and working with metal.
My first project will be a toy metal skidder for my 4 year old son. I have it drawn up in Inventor so now its time to start cutting and bending!
I will post pictures as I go and as time permits.
Does anyone have a source for tires? The scale of this will be Mighty Tonka size.
