Adults, from left to right: Vincent Ambrar, Fredison Mombrasar, Andreas Mombrasar, Elisabet Dimara, Delilah Mombrasar. The kids were moving around too much for me to get their names straight.
Their address is:
Pandai Besi Awak Soba
West Papua Indonesia
Note: If this instructable wins any contests, I'll send it to them. They could do amazing things with it.
Step 1: Chainsaw Powered Sago Grinder
Step 2: Chainsaw Sago Grinder Billboard
Big chainsaws are plentiful here because of the timber industry. The area has valuable hardwoods sought by Malaysian Chinese traders.
The traditional method of making sago starch is to fell a sago log and pound the insides with wooden hammers until the starch grains are separated from the fibers. I've read that even that way, it's 1/10th as much labor as rice cultivation. With a power tool like this, it would take very little time to produce large quantities.
"Pandai Besi" means "blacksmith" in the Bahasa Indonesia language. Just like our word, it literally means "iron pounder"
Step 3: The Product Line
The local stores carry mass produced machetes and sickles like we have but no one wants them. The local people appreciate a finely crafted steel tool made to exactly suit the work they do.
Step 4: Prices and Volumes
This is an impressively well organized operation.
Step 5: The Forge
Step 6: The Bellows
The gasket material is very soft and hangs down on the upstroke, allowing air to pass around it.
It looks like these gaskets are made of soft foam. I've also seen them made from many layers of woven plastic bags.
Step 7: The Tuyere
Theirs is made exactly as it appears, there are no valves. The iron rod in the middle is only there to set the spacing between the two nozzles that blow air from the pistons.
The nozzles blow air at a hole in the side of a slab of tile or stone that stands vertically.
The side blast probably reduces the problems with clinkers clogging the tweer. That's a chronic problem with American forges, which blow air from below.
Andreas lit some wood shavings and piled charcoal on them. Elisabet worked the pistons and after a few strokes the forge was roaring.
Step 8: Ambai Style Canoe
I didn't ask if they have relatives there, but that island has a strong blacksmithing tradition.
The crossbeams are exactly 1 meter apart, which is how much room a paddler needs.
The outrigger log is a hibiscus branch, which is very light wood.
Step 9: Huge Dugout
I think it's made from a smaller log which is spread open with steam, but I haven't seen it done.
I think the style is from Ambon Island, but I could be wrong - anyone have better info?
Step 10: Cocounut Grater
You hold half a coconut against the spinning cutter and put a bowl underneath to catch the grated coconut.
The ornate wooden thing in the foreground is a speargun with a trigger mechanism made from a nail.
They also make really nice traditional coconut grating tools.
I bought a couple of those, when I find the photos I'll add them.
