Hi Kevin - Good to see Stearman is back on the bench.
Look forward to seeing the progress.
My " longest" build was 15 years, Spit from a plan.
Catch up soon.
Regards
Colin

Considered how i would attach the windscreens after painting so come up with this effective solution.

1. lay up some glass cloth on a backing sheet to match the fuselage profile

2. Bond the windshields to the moulding and finish to size - they can then be painted off the model

3. II'll make some predefined locations so they can be cleanly fixed after painting

Undercarriage - ABS fairings trimmed to shape - Leg fairings fabricated with a bit more ply steaming and shaping

Ive previously covered the swivels (some years ago)
Ive reduced to clevis lengths by annealing , re-drilling using a jig, cutting off and re-shaping.
The rigging wires are terminated by silver soldering an M2 screw to fit the clevis using SS band from Mick Reeves models

I will upgrade the panel pins with proper nuts and bolts

A few interruptions by the head gardener this week but finally silver brazed all the rigging straps. Fabrication started by sawing the full depth of a cheese head M2 screw and a V slot ground in the strap. Flux applied and screw inserted into 2mm hole in a fire brick for brazing.
