Assemble ABS

Cowls and

Wheel Pants

Basic skills, advanced results by nek Ben

hen you buy the latest and greatest kit, chances are

pretty good that the included vacuum-formed ABS plas-

tic cowl and wheel pants will need to be assembled.

Because of the assembly required, many modelers don't give

these ABS plastic parts a second thought; instead, they toss

them into the spare-parts box and opt to use aftermarket fiber-

glass replacements.

The truth is, the ABS parts in kits are usually of good quality

and don't require a lot of work to produce strong, durable, light-

weight cowls and wheel pants. The techniques and tips present-

ed describe how I assemble ABS parts for a one-piece look.

To produce a good result, you'll need some basic materials

such as fiberglass cloth, glue for plastic (or thin CA), putty,

styrene plastic and spray contact cement. These are used to

assemble and strengthen the parts and improve their looks. For

First, trim the parts for proper fit. This step determines how much

extra work you'll need to do later. The more thorough you are

now, the less filling and sanding you'll need to do later. Be methodical

with this step. The cowl and wheel pant parts should fit together easily

and not have to be force-fit.

this article, I used a cowl and wheel pant from Midwest's

giant-scale CAP 232. Let's take a look.

When the parts have

been trimmed but

before you glue them

together, scuff the

inside of the cowl

and wheel pants

with 60-grit sandpaper.

This will give the epoxy

(applied later) something

to grip.
