My project came with the largest sewn baggage compartment possible with the series 5 fuselage.

In my pile of parts I found a cardboard template for the baggage compartment, but I did not find anything to make the floor out of. I have read that it is balsa core material and that was about all I know. I assumed it was a sandwich panel.

Well today I needed to run to my hangar to look in my 912 cowl box to aid in selling that complete set of fiberglass parts and I found two things I was absolutely sure I didn't own: The fiberglass glare shield piece for my instrument panel, and a flat box with two pieces of end grain balsa core material. Score!

I can't fathom that the balsa is usable without skinning the top and bottom with fiberglass or maybe even super thin aluminum sheet.

Is the core material normally all that is supplied or should I plan on doing some fiberglass wet layup?

TIA
