Title: Using Nitrate
Post by: James Mills on December 01, 2007, 09:01:01 PM

I'm thinking about using Nitrate for the base on my next plane.  It's going to be a built up wing, at what point do you switch to butyrate?  I've read one or two articles where they said they used the nitrate to shrink the silkspan.

Thanks,

James

I use 2-3 coats of nitrate on the wood before silkspan, then for the first 3 coats over the paper. Sticky stuff. Makes a good base for whatever you want to put over it.

I apply nitrate to everything except the open bays.  I use nitrate as the entire substrate and for attaching the covering.  I also use the nitrate to begin the filling process on the solid wood areas.  I use Sig Supercoat (high shrink) clear to shrink the open bays, then go to Sig Lite Coat (low shrink) all over for the rest of the clear.
