I am out of thin CA glue again. I just bought a large bottle thin CA glue last week. I drove across town to the Hobby shop and they are sold out of thin CA glue. "NOW WHAT"!!! I bought a large bottle of thick CA glue and retuned home. I squeezed 1/3 of a bottle of thick CA glue into an empty thin CA bottle. I filled the bottle up with acetone and shooked it up. I did a test and it works just like thin CA glue. I filled the 2/3 bottle of thick CA glue up with acetone too and shook it up and now its medium CA glue. I got 2 bottles of CA glue for the price of one bottle not counting the 10 cents worth of acetone that I used. This little trick saved me $10.00.

I think I'm going to give that a try. CA is so darn pricey.
Does anyone know of any downside to this idea?

Only downside I can think of at the moment might be reduction of shelf life due to pretty rapid evaporation of the acetone?

Dont worry about the mule going blind 'til you get the cart loaded!

Or strength! The CA wicks into the wood and then bonds things together. If the acetone is wicking into the wood, there is less CA there. I don't know the "ins" and "outs" and chemical makeup and all, but I am sure this is not how they make the stuff in the first place.

It might be good to do a few test strips to see how strong it is, how brittle it is, how long lasting.

Len:
Definitely good idea on the test strips, but isn't that why the liquids we use are thinned---for better penetration and coverage? If the acetone is wicking into the wood, should it not carry the dissolved CA with it, creating a better bond? Or at least, no worse? It seems there would be less CA present, but what is there would penetrate/hold better, if the dilution was not to an extreme. Yes? No? Am I up in the night? Opinions, please.

You can dilute epoxy with alcohol, but if you dilute it 50-50 and then use the same amount, you will end up with half the amount of glue for your glue joint. Same thing goes for the yellow carpenters' glue. You can dilute it with water. However, if you use the same amount, you will end up with half the glue.

That, plus there is the unknown effect that this dilution makes upon the product itself. Will it weaken it? Probably. Will it make it brittle? Don't know. Again, I would think one should do a bit of testing first on something that doesn't matter.

I am guessing that you and I would be a little put out if we discovered that "Warm Stuff" was suddenly cutting their CA 50-50, using a base thinner to get by cheaper. Why, then, would we do that to ourselves?

I would be a we bit leary of any glue that was cut in this way.

for really cheap prices on C/A go to Lonestar balsa
and order some real large 8 oz.bottles and some small caps and empties

click on the link and go to the glue section

Just for your info to any one out there that buys the large quantity of ca, this stuff will last for several years if you keep it in the freezer! It takes about 30 minutes to thaw and does not loose any of its abilities to glue wood or fabric. The last 3 airplanes I've built were glued together with ca that was in the freezer for well over 18 months and they have not come apart after numerous flights. It doesn't seem to make any difference if it's thin, medium, or thick ca.

Dumb Question time, again! How much CA glue does it take to build a .35-.40 size model? Is the "odorless" sort any less of a health hazard than the regular kind,or should I try the non allergenic sort? Thanks
