| F22 Bulkhead shown with harder points for canard and corners. | F28 Bulkhead. |

| Seatback with 3" wide heat duct. I later made a 2" wide map pocket. The seatback is 4" wider as are all bulkheads. |
This is the back side of the instrument
panel. Cutouts
for the legs are 2". wider per side and 1"
taller. The
top portion has been removed for slightly better

| I made these landing gear bulkheads but later modified for middle sump tank. | I am using infinity landing gear so this area can be used for fuel. |
|
|
|||
| Firewall with engine mount tabs. I later changed the firewall top to get rid of the fairing shape. |
|
|

| The screws shown have been ground down on the edges to help the screws have a better grip when floxed in. | The temporary Firewall. I used to wonder why it was needed but as you put the fuselage together it becomes obvious. Glad I followed the plans. |

| This is a digital thermometer I built to read the temperature of my epoxy. I use a higher temperature cure. I use Poly Poxy from Aircraft Spruce. It has a higher tensile strength if I heat cure it. I make tents around the bulkheads (actually all parts I make) then I blow hot air into the tent using an electric turbo heater. My typical cure temperatures are from 130°F to 160°F. | You think this looks bad you should see my drivers license photo! When I first worked with this epoxy and fiberglass I got all arrayed in this getup. I had done fiberglass before on some earlier projects. Those previous products were much more toxic. So, I started out this way with this project. One day I removed my mask and could hardly smell a thing. I then realized that it wasn't necessary. Now I don't use a mask, or gloves. I could do it in the nude but I don't think that picture would look look any better. |
