Return to the BUILD

In this issue, we will build the smoke generator assembly for the third funnel.

We have built these Smoke Generators before, so this steps should feel quite familiar.



Materials: The Spring is metal, the Filter is cotton, and the rest of the non-electrical parts in this issue are plastic.

The Third Smoke Generator

Step 1

Press the long, straight pin of the Spring fully into the center at one end of the Filter, as shown:

Insert this Filter assembly (Spring end first) into the Tank, as shown. Once installed, the Filter will stick out the top of the Tank and you should be able to push it into the tank against the resistance of the Spring:

Step 2

Fit the Smoke Generator into the Smoke Generator Holder with the wires fitting into this notch, as shown:

Step 3

Fit the two posts of the Interior of Third Funnel down into the matching openings on either side of the Smoke Generator Holder, as shown. Then, secure these parts together from the other side with two (2) EP screws:

Step 4

This Smoke Generator assembly can now be fitted over the top of the Tank, as shown. This is meant to be removable so the tank can be refilled, so do not glue these parts together:

Using the Plastic Band, secure the wires of the Smoke Generator to lower part of the Tank, keeping the wires taut as shown:


Our third Smoke Generator has been assembled and is ready to be installed into our Funnel! Keep this assembly and the unused Grille safely stored until we need them again later.
