hehe, well, that's what my partner says, so I guess he's wrong.

I'm not saying that wood glue isn't better than CA in some situations, but making general claims without supporting them, or making "I think..." statements, doesn't really help.

well its specifically called wood glue for a reason but I guess there are other glues better suited for putting wood together...

FRom personal experience wood glue is stronger then CA glue, However when it comes to events such as bridge and boomilever i have found tht Wood glue is just too strong and heavy. also it doesnt quite seep in enough into balsa or bass. This is where CA glue is better. its not too strong and it is light. its like when using types of wood, why has everyone settled on Balsa and bass wood? because for its strength and weight it serves the best purpose. I mean Oak wood is extremely strong but le me tell you most everyone with any sense wouldnt be caught dead using Oak for their bridge because it is too heavy and too strong for the purposes we need. Personally that is why i believe CA is the best because for its weight it is as strong as possible. like with building your bridge. you want it to fail at 15kg, because then you know you havent over built the bridge.

Is CA glue similar to Krazyglue???

Check the ingredients of Krazyglue. It'll say "contains cyanoacrylate" if it has is.

yea, i think wood glue is just too strong, i mean when i use super glue, it always breaked at the wood, not the joints. And i'm not even using the liquidy type of super glue

I have built numerous bridges out of both wood glue and CA. Guess I'm the only person to support wood glue. Although it is heavy, I have found the glue to be very useful for shear and tension. I have mixed it with weldbond and water in order to get it lighter. The weight is somewhat significant, about 0.5g as oppose to .25g by CA but to me it isn't enough to switch to CA. With CA i found constant problems with the glue. I find out sometimes i put glue and it stays but is not fully connected and just partially connected but since it is strong, it will stay for a while. When it comes to testing, i found it that it breaks there because of the glue. Wood glue expands so if there is a gap it will fill it while CA will seal the wood. Don't get me wrong, I have built very good CA towers and bridges. However wood glue has a more consistent and higher average ratio.

what do you mean by "partially connected" that's why your suppose to put light pressure on the two pieces your gluing, so when it dries it'll dry attached together.
