Is there a formula for making home made airplane glue? I was wanting to experiment making glue such as Sig-Ment.
I'm 64 years old so I'm not looking to "Sniff" the glue .I heard about some person making glue from acetate or maybe photo film (undelvolped) mixing it with acetone and some other chemicals.

Any one heard of this or can give me a formula ?

Thanks

I think in the 30s they dissolved celluliod glasses frames, combs and other household objects in some type of solvent to make glue. MEK might work to dissolve it.

Isn't Ambriod basically dissolved celluloid or cellulose?

I've heard of dissolving photo negatives, toothbrush handles, and other plastics in acetone to make glue in the old days..........but I'm not sure if modern plastics would work the same as the old acetate types.
My dad told me that when he was a boy his dad brought home some sort of lacquer from work and they left the top off for several days to thicken it into glue.
By the way, THAT ticked my grandmother off to no end! [

Old acetate film and acetone to make a glue, used to be used and still is by an old timer I know, who still uses tissue to cover his planes.

Cheers.

Back in the 30's this was quite common, use old photo negatives and a little acetone from the local drugest and you had your glue.

"...an old timer I know, who still uses tissue to cover his planes."

I'm not an old timer and I use tissue and nitrate dope to cover many of my planes. I also use silk and dope for covering. To me, Monocote just looks like shiny plastic.

But, necessity is the mother of invention. I once saw an old model built during WWII that was covered with silk cut from an old dress, it had pink and green flowers all over it. The tires were pessaries. Point is, there were times when certain materials like glue, rubber, silk, balsa, etc. were almost impossible to get. Modelers found ways to fly planes anyway.

We are SO, SO lucky today. Anything and everything we could possibly imagine needing for our models is readily available to us. We can even buy pre-built, pre-covered planes called ARFs!

I work in a lab and pure acetone can be very dangerous to the central nervous system when inhaled or absorbed through skin. I would use extreme caution if you attempt to do something like this. When we handle it we use neoprene gloves and work in a fume hood. Just something to consider. Plus it's extremely flammable! Don't mean to be so negative but I would rather stick with stuff like titebond. I'll get off the soap box now.

sounds like a real bad idea to me. Why not use the stuff you know works and has been tested and proven.

I would say our "old timers" have done the job and testing and proving many times over. That doens't mean I'm headed to the store for glue making supplies. I still think it's interesting. Something for me to store in the back of my mind for a possible future "MacGyver Moment". Ya never know.....

Anyone have recipes for "safer" homemade glues? Something water based maybe?

elmers glue or titebond available almost anywhere.sometimes it is cheaper to buy ready made products than to make your own..kind of like buying a horse to make a bottle of glue.

Might just as well re-invent the wheel too.... Am I missing something? Why would anyone go through the hassle of making it?

For the same reason guys make their own target arrows or bullets or fishing sinkers, or fishing flies, diesel fuel, or beer, the list goes on. Looking in a machinist magazine I saw an article on making your own .60 size engine from a block of aluminum. Why!? when you can go buy one!? It's a hobby. People participate at different levels. Some buy ARFS, some pay others to built kits, some build from scratch, and apparently some are interested in making their own glue. It's the "I DID THAT!" principle. I suppose it bothers me more that some people would want to hinder an inventors/creators goals. Ya never know....while making homemade glue someone may stumble across a whole new formula never considered before. In two years we could all be paying $10 a bottle to buy HIS glue. It's happened many times. bla bla bla bla.....I think you get my point.

As I said before. It's alway nice to know I can grab a roll of film and a can of acetone in undesireable circumstances.

Homemade Glue Websites.

I found a few websites some of you may be interested in.
This site has one at the end called liquid cement that looks interesting.

This site tells how to extract Casein (used as glue) from milk using vinegar.

Interesting article about Casein glue used in full scale aircraft.....

The old glues were home-made from celluloid film and other items dissolved in solvent. The celluloid itself was very flammable. The resulting glue is genuinely too dangerous to be worth fooling with. Many movie films from those days have been lost because of the unstable material. Hide glue and casein glue are still in use and reasonable alternatives.

Make your own "Tite-Bond". Go down to the local slaughter house and buy some hooves. Boil them down to make what's known as Hyde glue. My grand dad used it to glue the front and backs of violins together. It stinks like 7734 though!

Rodney

Shag555, hide glue and aliphatics are two totally different types of glue. Titebond is an alihatic.

shag555

I really don't know that much about it... I just figured I'd add the two lincons. One thing about hyde glue that is nice for instruments, and probably bad for airplanes, is that with a little steam the glue will work its self loose. With a little prying, violin tops and bottoms come right off.
