I spent half the day outside finishing up Timber for a long-time FC member. Then I turned my attention to... well let's take a look.
Modeled after a well known mod box, but all wood. This unit has the GonG but no epoxy. Notice the side battery compartment, the battery will load from the side, snap in between contacts. I'm working on the door concept right now. The switch (momentary button) will sit atop the unit. The unit will be capped, top and bottom (just batter side cap on top, full cap bottom). Eventually I plan to eliminate GonG.
What you're lookin' at here is the bottom of the unit, before cap. The COIL heater is on the other side of the 1 inch disk with the 2 leads coming through. On this prototype, the switch is not under the heater, but above the battery and will be thumb operated. The battery slot (right) fits a 20700 battery. I'm not sure what way to go here, dual capability, just 18650 (smaller, lighter), or just 20700 (potentially better).
Here's the unit with the stock for the bottom and top.
