My choice for a CA substitute that bonds balsa very well is the Super Phatic Aliphatic Glue that was mentioned in post 25. As ghitt says, keep the syringe needle tip in water and flush it out with a syringe full of water after use. I think it's great and hope that Hobby Lobby continues to stock it. I like its wicking properties as it is comparable to thin or medium CA. I have tried thinning Tightbond but I think that Super Phatic makes a stronger joint. I can still tolerate the odorless CA if used in small quantities but now use Tightbond II, Super Phatic and epoxy due to my acquired intolerance to CA.
