Quote: "WHAT! Build a gas job with white pine? Now wait a minute, pine isn't heavy. As a matter of fact, it's a soft wood, while balsa, as probably few of you know, is classed as a hard wood (all trees that shed their leaves in the fall are hard woods).

After some experimentation and the building of one gas job with pine, it was decided that pine was satisfactory; in fact many people prefer it to balsa.

Construction time was about the same as with balsa, although it was a little more difficult to work with until we learned the different tricks. For instance, on the first attempt we used Weldwood in preference to model airplane cement, thinking the latter would not do.

However, when it dried it was so tough it could not be cut with a razor blade. We then had recourse to casein glue, which while satisfactory in other ways, took too long to dry.

As a last-ditch resort, model airplane cement was tried but it did not work very well until a fillet of cement was added (much the same procedure every model builder uses for square fuselages). This did the trick; the cement held so well that the wood broke before the cement.

Wood in sizes up to 1/16 can easily be cut with a single-edged razor blade. The ribs were cut around a tin can template in this manner. Curved parts were eliminated wherever possible because pine splits very easily. But wherever they were used, they were glued together in straight sections and then cut to shape.

Two tools that proved priceless in making this model were a Syncro Jr saw and a variety of sandpaper blocks bearing rough, medium and smooth sandpaper. Remember, the only difference between the beginner and the expert is that the expert uses sandpaper.

As for the weight, pine when properly used will cause the ship to weigh no more than the old type of balsa ship, while possessing the advantage of great strength..."

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
