The Recycled Jet Engine

Step 5 The Exhaust

---

Having both my main housing and flametube completed, my vision was piecing itself together much more nicely than anticipated. A nearly imperceptible, yet present, flame of excitement sparked within me. I knew my next move was to complete the exhaust.

After what you've gone through so far, this part is really a piece of cake. This is the green part in the diagram.
Fist I selected a can slightly smaller in diameter than the one we used for the flametube. This will be referred to as the "exhaust can".
Next trace the exhaust can onto the back of the main housing. This was pretty easy because it lined up perfectly with the grooves on the bottom of the can.
Draw another circle with a smaller diameter that you will cut along on the bottom of the main housing. We need a smaller diameter than the actual exhaust can so that we have room to JB Weld it.
Use a ruler to draw yet another "X" type shape on the back of the main housing like before. There should already be a hole marked for the shaft to work around.
Cut out the triangular-like pieces on the main housing.
On the exhaust can, draw a circle on the bottom to be cut out. Again, there are awesome grooves to help you. You'll want to keep the resulting disk in tact for the fan shaft later.
Finally, JB Weld the exhaust can to the main housing. This combination will now be referred to as the "housing".
