Just finished my 1/24 scale "Perkasa".Frankly,I never new I had the patience!
Have started a 54" USS " Crocket" and have reached the balsa bending stage and have never done this before.The Crocket has very tight bends around the bow area,and involves a tight "knuckle".
I spent much time looking at balsa bending,and the use of ammonia as a fibre relaxing medium arose.
By experimenting, I find that a 50/50 solution applied to the area to bend for just a few minutes,then wiped off,renders the wood extremely pliable.
Gloves and eye protection must be worn,with good ventlation-
It does work!!.
Hope this is of use to someone.
