Builder Tip #107 from HomebuiltHELP 
Watch: New Modifications to our Fiberglass Engine Cowl
Watch the techniques used by an expert to modify an engine cowl
Making major modification s to an off-the-shelf engine cowl is within your abilities if you understand the techniques. This week's Tip demonstrates basic fiberglass construction techniques by showing how to add a new rim border to the cowl's prop opening.

Using the polyurethane foam product shown in last week's Tip, a new rim is formed and shaped using a creative technique. It is then covered with fiberglass cloth and then resin is applied . Multiple layers of cloth are added until the desired thickness is obtained.

Watch and learn how easy it is to make modifications to fiberglass components with the example in this Tip video:

Interested in learning about    solid riveting techniques for building aircraft like those made by Vans Aircraft and others?
Working with    "solid" rivets  (the ones that need a bucking bar to be held on the back side) can be intimidating if you are not familiar with the relevant tools and techniques. As compared to blind rivets which are relatively easy to work with, solid rivets need a little practice and some specialized tools.

Once the confidence in setting these rivets is acquired, the opportunity for building a  greater variety of fast, sleek aircraft becomes possible (For example, the majority of Vans aircraft models are predominantly built with solid rivets).

Our popular DVD: "   RV Rudder Workshop" demonstrates and explains the basic techniques and tools for working with solid rivets. As an example of putting these skills to work, a rudder for the Vans RV7 is built in a step by step presentation. You cannot get a better preview and understanding of what it takes to build a Vans aircraft with this informative DVD.

Become enlightened today with the details of solid riveting by visiting the webpage below and ordering a copy of    RV Rudder Workshop!
