Title: Wicking CA
Post by: Kim Mortimore on May 22, 2012, 07:23:27 PM: How far will the thinnest CA wick into a joint with no gaps? I need it to wick 1/4".

Thanks.

It will wick four inches or more, right to your hand holding the bottom of the part being "glued" and the wicking will attach your hand to that part. Been there, still do it. Damn.

Ty,
Got any pix to show us? LL~

Oh, it will wick farther than that. It will wick four inches or more, right to your hand holding the bottom of the part being "glued" and the wicking will attach your hand to that part. Been there, still do it. Damn. H^^ D>K LL~
But it does require a right amount. Use the long tubes that attach to the spiggot, then you can put that stuff right where you need it. H^^
LL~ HOW TRUE! rd

Post by: Dick Pacini on May 23, 2012, 01:36:07 PM: Yes, CA wicks very well. I have glued a part to my hand. I have glued my sneaker to the floor. (watch those drips) I have glued leadouts to the guide tubes. I have glued a level to a wing. I have glued a wing to the bench. (again, watch those drips) HB~>

This is a sticky subject.

I have glued my finger to my tongue. My finger was burning so I stuck it in my mouth. REAL BAD IDEA ~^ HB~> HB~>

I have done it and the plane had quite a few flights before I totaled it at a contest. No stress cracks anywhere during it's lifetime. But, it takes extra work to do CA joints right. Like extra holes on the ply lamination on fuse sides. Baking soda or micro balloons for gap filling. But, without proper ventilation the CA fumes will get to a person. Don't ask me how I know. H^^

Oh, by the way, take a scrap balsa block that is soft. Start putting CA on the end grain. I have had it comeout at the other end of a six inch block of balsa. Now moisten another block of balsa and try it. The CA will not go too far. It is the absence of air and sometimes moisture that causes CA to go off. You've seen the little puff of smoke if you use enough of it. D>K
