Shimmed top fuselage up 5/16" to center for T-21 ( 1 5/8" x .058) cross tube at STA O. Cut/fit T-21 tube using the smooshing tool and then hammered on anvil to fit. All done cold, no heat. Fit remaining T-14 (7/8") cross tube, T-11 (3/4") diagonals and small T-5's (1/2"). Made first wind chime while fitting diagonals. Guess that ain't bad for "amatuer built".
