I am building my first full body in 20 plus years
Engine is inverted
Need picture of balsa blocks to nose ring
how do you cut the nose ring
The lite ply came apart when I tried drilling the center hole
how do you cut the 1/2 or 3/4 Balsa to go around the engine shaft
thanks

In general, bolting the wood to the spinner backplate would be a good start. You could laminate a stack of balsa and plywood with the grain going different ways.

Cut the nose ring with a jigsaw. I use light ply with a front surface of 1/64 hard ply, which makes the edge much less prone to damage. Obviously, cut it well oversize so you can file/sand it down to an exact fit.
BTW, before you install it, attach an offset sanding disk to the engine shaft and sand the balsa/engine mounts to the right plane by rotating the engine back and forth.

A rasp or two can be rather usefull .
just whacking on a square ply plate with a hole in it ,
useing the spinner & a cardboard spacer , to set the gap . ( as in Fitted With the motor in , aligned , to set true )
Then endless refittings of engine ! S?P, a ball pen line around spinner , Fair In with sanding block .
if Yr gunna F/glass cloth it , you need to go a trifle undersize , so it finishes matched .

Juan,
OMG! Ohhhhhhhh, My Gosh!
You're work is the cleanest I've seen. H^^
I should Post photos of the front of my models just for the laugh.
27 pieces, looks like a porcupine till I sand it down.
