Balsa is stripped using a simple balsa stripper and single piece of 1/32 inch balsa. Total cost: $8.50. Total difficulty (1). This is easy.
Step 2. I weigh each 36 inch strip. Balsa strips are 1/32 inch by 1/16 inch. Pieces weigh between .145 grams and .360 grams each. Sort from light to heavy. Heavy ones are stronger and used for wing leading edge, wing center rib, and certain braces which are more subject to abuse. Lighter ones are used for center ribs on the wings, stab, rudder and fuselage.
I did use .004 boron on the inside and outside of each horizontal fuselage outer pieces.
Cheers! Balsa cut and frame built in 1 weekend.
Just be very careful to align the balsa right to the plans. Cut the pieces and sand the tips to get them to fit closely but without creating stress. That is what creates warps or mis-alignment later when assembling.
