Well, I got my 3-48 package of T nuts, four packages actually, ebay, on suggestion from another modeler. Don't remember who, but thanks for the advice, I took it!
Now I can epoxy my gear rails in place which really brings building tasks almost to a close.
Remaining:
Fit 3-48 T nuts to gear rails.
Epoxy gear rails in place.
Attach magnets to the motor excess hatch.
Attach flaps.
Attach elevator.
Make last bends in the wing gear wire.
Bend tail skid wire for tail wheel.
Silk nose area after fitting spinner.
Block sand the entire model.
Prime with Robert's 540.
Remove 90% of Robert's 540 with 360 sandpaper.
There's always little odds and ends and tweaking between tasks.
Then it will be time to shop for rattle cans.
Paint is close.
