I forgot to mention that IMO you should just use the CA to tack things in place and actually use a good wood glue for your construction. I use Tite Bond II myself but Elmers is good and there are other good brands too. I got mint thru Tower but I think you can get it at Home Depot or Lowes also. Epoxy for the firewall and fuel-proofing 15+ min type only and if you thin it, just add a drop or two of alcohol. It thins out very quickly to a brushable consistency.
