Hi Juan,

I'm currently building a Great Planes P-51D with retracts, and just installed my first wheel well. I used 1/16" balsa. I edge-glued several pieces together, then hunted around the house and shop for a can or bottle of the diameter I needed for the well.

I found a hard plastic bottle of just the right diameter. I wet one side the balsa, wrapped it around the bottle and trimmed it to the right length. Then I glued the ends together with CA and slid it back on the bottle to dry. When it dried, I smeared a light layer of glue over the outside of it to help it hold its shape. That was not necessary. I should have coated the inside with finishing resin. That would help it hold its shape AND fuel-proof it.
