Slot car guys?
I collect HO scale. I got tired of the same old, so I decided to build some bodies. At the time I was really into Rat Rods. Here's a few in my collection.
All made from sheet styrene, super glue and a spray bomb.
I cast this body in resin based off of a HW body. The chassis was built from tube stock. Same thing for little red in the background.
Here's a little before and after. Tyco 40 Ford.
