    Okay... was able to launch Big Shot on an O-3000. Due to high winds, weather cocked a bit. Main out at 11,385'. Nevertheless recovered 1 mile away, directly next to the farm entrance road. Still struggling with zippering the booster. Happened last year as well. Will change setup slightly next...

    Cutting 4" G12 body tubes

    Gonna try a 12" diamond blade on my miter saw. Thanks everyone for your responses. BTW, has anyone tried cutting these tubes with the blade running in reverse?

    Smooth fillets

    Try using Metalset epoxy. Easy to work. Sandable. After I tape off and apply the Metalset A4, I wet my fingers with rubbing alcohol and smooth the fillet. Once hardened simply sand with 120 grit or finer.
