Default RE: Kit building glue

Elmers wood glue and Titebond have held strong over time. I built a Wanderer glider back in 1981 and still have the well worn wing hanging on the wall. The Bridi Trainer 40, which I still fly today, was built the next year. Both the glider wing and the trainer glue joints are holding strong after all this time. Wood glue is great and so is the patience required when you build with it. Sometimes I long for those days on the work bench in high school when I would frame up a wing, turn out the garage light and let it sit till I got home from school to unpin it the next day.

Hope that helps,

Tony

I use Titebond. But I make sure I clean up any excess real good. Mostly because I'm a weight nut and when sanding sheeting or other areas it makes a big difference if you get rid of any excess. I can't use CA it kills me. I loved using Ambroid but build time is a little longer in my opinion.
klord125,

It wouldhave beeninteresting if you had been able to back up the big difference with figures; at least an estimate.

Zor, My point wasn't from a weight thing. Thats just me from 1/2a days and haven't been able to let it go. I was refering to sanding the glue. It makes a big difference when final sanding from an ease stand point. Just my .02

Man, what great memories.   We used to build our planes in woodshop in school.   Helped in our grades but we still had to make birdhouses, whirlygigs, and simple furniture for the better part of the grade.

Good to, the school board let us use a schoolbus with driver for a weekender to Patuxant River, Maryland for an AMA contests.  Those days are long gone and not likely to be repeated.

You said that you were a weight nut and I interpeted (I think logically) that removing the surplus was saving lots of weight of the model.

I was suggesting that you could havegiven an estimate ofhow much weight it was saving.

I like wood glue, Ambroid (Sigment, Duco) and epoxy. I only use CA to fab jigs. For me, CA is terrible if it get on something that needs sanding.
As an aside about weight savings: the 1933 Darmstadt D-28b 'Windspiel' sailplane was built with a primary goal of a very small, efficient, manoeverable and lightest sailplane possible to take advantage of small thermals. Quoting Martin Simons' book 'Sailplanes 1920-1945'- "All joints were carefully wiped before the adhesive set." is found on p82.
Interesting stuff that goes to show there is nothing new under the sun!

I have never weighed the excess glue that I removed. Its not that big a deal on larger planes. But it can be on smaller 1/2a and such planes when grams/ounces are a big deal.

*Titebond - For general building. No need to work fast, its just a hobby.
*CA - Little tack jobs, small repairs, ca hinges, maybe a fiberglass patch. Too expensive to use regularly.
*30 min epoxy - High strength areas.
*Less than 30 min epoxy - thinned with denatured alcohol for fuel proofing.
*Gorilla Glue or any other polyu foaming glue (I used to use ProBond, cant find it anymore) - Where 30 min epoxy wont work. Like some windshield installations (very fine bead), wing mounting joints, robart hinges (couple of drops does fine), and wing sheeting.
*GOOP - Stick anything to air. I use it to glue parts to Polyester glass fuses (epoxy doesnt stick so good to polye), like air tanks to a polye fuse.
*RC-56 (or equivalent) - for canopies that i dont screw on.
*JB Weld - Thinned with denatured alcohol makes a good heat shield inside a cowl and on the fuse.
*Hobby Finish Reson - For glassing to wood, also makes a good filler when mixed with micro balloons or saw dust. Sands like hard balsa.

For making cowls - Thinned 30 min epoxy or finish reson. Finish reson is a little more stiffer than epoxy. Both are durable.

The only reason I dont use West Systems reson is cost and quantity. I dont need so much. UNLESS - I'm making a glass fuse which I havent done yet.

What is the best glue to use for laminating large doublers without worrying about warping?

I use titebond. Sandwich them between two pieces of straight wood and weight it down.
