thank you and welcome to FineScale
Step by step pictures follow because I wanted to show how I made the front and rear bumpers from scratch
I didn't have any styrene shapes like this on hand so I started with a piece of acrylic cut from a CD jewel case
This CD case parts was needed for a solid core to glue the rest of the parts around and onto in a laminate fashion
I used .010" thickness styrene sheet to cut out the parts and pieces for the bumpers
Plastruct stock square rod was cut, drilled and shaped for the rubber bumpers on the front
notice I inserted a scrap piece of the same acrylic of the same stock before drilling to avoid tearing and breakage of the fragile styrene
brass wire is measured, bent and cut to size for the front bumper
The front winch guide rollers assembly
For the rear I made a drawing because I got tired of running back and forth between the computer and the bench which are in two different rooms
keeping everything nice and square while the glue cures
the bumper assemblies were tac clay tacked into place for the pictures
As soon as the bolt head arrive in the mail, that will be the final details to add to these
thanks for looking
