Sealed all of the cut edges with CA before sanding. Several coats of primer filler were needed.

You can see the scale difference between the kit's cardboard version and the scratchbuilt one (closer to scale).

Why did you feel the need to seal the cut edges with C/A before sanding??

Superb craftsmanship.

How are you getting the perfect cut circles?

Hi John! I found out (the hard way) that some balsa sheets are prone to chipping very easily. So I rough cut the outline, run a bead of CA along where the finished edge will be and then I can sand/file/ream out with less chances of breaking out or chipping. It also stiffens and hardens the balsa so that it almost feels like styrene or plywood. poppy - Thank you! It is very flattering to recieve a complement from one of the Masters!!! Jedi - Since I don't have a MotoTool, I resorted to wrapping some sandpaper around the sharpened end of a pencil. I then reamed out the roughly punched holes. Takes a lot of time!!! (ugh!)

BTW poppy, since you've finished the fabulous Hellcat, what are you working on next?

Dremel (rotary) tools are great for some things, but for uniform holes and avoid chipping and splintering, forstner bits are the best. Dremel tools are to high torque and unless you put them in a dremel drill press I forsee problems. Any wood tends to tear, because you are cutting across and with the grain at the same time. Forstner bits will put its' pilot dead center and cut and lift the wood out. Any clear through holes should be backed up any way by scrap anyway to avoid tearout. As far as bezels, since you seem to be laminating, if you would ream out the hole from the backside it would create an undercut which would allow only a small piece of the bezel to show through with no cutting or trimming necessary.
