all this talk about CA reminds me of a video I saw about CA as a sealer. For the life of me, I cannot find the video i initially saw. So here is another one, some other "woodworkers" use CA as well. Might be a good indication for lathed plugs =p

I have not made balsa lures for years, but when I did I vacuumed them in what we call 'Airoplane Dope' here, which is probably what Kosta is talking about, "Celluloid" in acetone .
I have vacuumed my later lures in Prop a few times and it seems O.K but the wood I use now is a lot harder than balsa and really does not need hardening.
There is a 'How To' here- Post #39:
I am wondering about breathing and using your finger to push CA glue around as a sealer, I thought it had cyanide in it????????
Oh yes, I still have some of those old lures (about 25yo) which were dipped in Dope and don't bother using it, it breaks down and cracks, breaking the paint and clear over it -
Try Propionate, should be much better then 'Dope' - BUT, you can't trick me, I am not going to get into that "Epoxies V Prop" thing .

Hahaha, let me guess, been there done that a few times hey Pete? So you got me thinking when you mention that your using wood harder than balsa; where does bass wood fall in the catagory of hardness/ floatation characteristics? I haven't done any work with basswood yet but to my amateur eye it seems like a good compromise between balsa & true hardwoods. Thoughts?

Thanks for the encouragement Prof! What are your thoughts in regards to a particular order of epoxy materials to gain optimum flexibility & resistance to penetration? For example if a person sealed with Etex, then did one coat of Etex for a topcoat, then a clearcoat of Devcon 2ton would that result in a lure that is more "flexible" as well as durable than say a balsa lure which has been sealed, topcoated, then clearcoated all with Devcon?
Also, I just want to apologize to Balsabee for somewhat highjacking this thread. I like to think that this lurebuilding forum is probably one of the most forgivable types of forums to highjack on because there is no such thing as wasted or useless info here!

Pikester- I have not had the pleasure of working Bass Wood, but when I was over there I did have the pleasure of feeling it, nice even grain and very light. I could not buy any because on my return, Australian Customs would have arrested me, then nailed me to the plank and floated me back. We are paranoid here (for good reason) about importing wood worms and borers, that would eat their way across the country like everything else we have snuck in over the centuries.
Saying that I would like to get hold of a lump, and I dare say I could probably buy some here somewhere.
Here is a link to a site with all your timbers and their properties - as you can see Bass Wood is 4 times the density of Balsa, but there are apparently a lot of grades in Balsa.
