Glue dry technique failure

burn

Don’t try this at home. I did and it didn’t work. I tried to use a lighter and a portable blow torch to add heat to make white glue dry faster.

 

As you can see, it really didn’t work. I had no idea of how flammable balsa was. Foam is also very sensitive to heat.

I had some luck using stray heat from my computer fan. This worked very well. So I got greedy and wanted to see if there was another way of applying heat.

To add insult to this injury it didn’t fly. I trimmed the plane quickly in their living room then tried to fly it off the balcony. Dreaming it would fly away and perhaps some child would find it.

Well that didn’t happen. It just headed straight down and smacked on the roof of some utility building.

  1. Yes, balsa burns like dry grass. Even heat from a magnifying lens will set it on fire. To get the glue to dry faster, leave the cap off and let it dry out a little in the bottle. Try heating the parts with a hair dryer, or heat lamp, before and after putting them together. Drier wood may facilitate the glue drying faster. Hot sun may have the same effect.

    To some extent this might weaken the glue joint. Glue must be wet to flow and soak into the pores of the wood.

    Foam will likely melt from the heat of a hair dryer. Try it on a scrap first.

    I guess I am patient. I let one thing dry while working on another. Plan the build sequence accordingly. Let the tip plates dry while cutting out the tail parts and tapering the stick. Let the tail parts dry while making the rib and hold down. Let the rib dry while making the motor hook. Let the motor hook dry while strapping on the wing and pushing on the prop. Let the whole thing dry while making the motor.
