Work on the cooling rack waits for some black paint (I just got some today). So in the meantime, I have lots of little odds and ends to take care of. Here are a few:
The ash has to be cleaned out somewhere. The easiest place is out the bottom; some of the woodgas guys have used ammo boxes extending below the bed, and so I decided to follow suit:
Welding on an ammo box is not easy ; the metal is very thin, and burns right through. So I covered my mistakes with some JB Industro Weld. Good stuff:
I also have to run "plumbing" for this thing. Every device has to be connected in an airtight fashion. So I am a plumber with a welder.... I have been plumbing with the same 20' gate pipe used in the cooling rack:
Here's the cyclone filter with an intake pipe:
Notice the double jointed bend. This is a little smoother, and so the gas should flow easier. It's only one extra weld to make. Same bend on the gas exiting the hearth, and a flange to aid disassembly later:
This long pipe will run to the starting blower. A tee off this line will go into the cyclone. Again, I will attempt to smooth the transition.
I went to Lowe's and bought some pipe caps:
No welding! Just screw them in.
Anyway, I have the paint now, and soon the rack will be back.....in black.
