At the far western tip of Papua, on the outskirts of the town of Sorong, is a place called Tempat Garam. This means "salt making place". The Mombrasar family of blacksmiths have their shop there. They build boats, make any kind of tools, and invent labor saving devices.

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:
Kapiten Patimura
Pandai Besi Awak Soba
Tempat Garam
Klawasi Sorong
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

Yohanis Mombrasar shows me one of their inventions, a chainsaw powered sago grinder. The local staple is sago palm starch. The sago palm grows in dense stands in fresh water swamps just behind a barrier beach. The whole trunk is composed of starch and fibers.

Step 2: Chainsaw Sago Grinder Billboard

The family has a knack for clear visual communication.

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

Here are some of the things they are ready to make at any time.

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 how much their major products cost and how many they can make in a month.
This is an impressively well organized operation.
You are not only innovative, you're staggeringly interested and observant.
We're lucky to have you looking out for us.
Sorry we missed you at the Maker Faire.
Keep up the amazement and inspiration.

Great contribution - thanks. I'm impressed with their technology. (The more you understand about technology, the more you respect these kinds of solutions.) Maximum respect to these innovators.

Is there anyway to find or get some of the hand tools they make? always looking for that sort of thing... seems the hand made stuff is made with so much more care and so forth than the stuff you can find in the big box stores here in the states...

Try sending them a letter to their addr in the ible. Maybe you know some missionaries to Sorong who could buy for you. let me know how it goes!

A friend of mine is a professional fisherman. He told me he made a fillet knife out of steel straps that were used to wrap around shipping crates. Tell them about that.

Note on the perahu (canoe). I'm pretty sure that the big one is natively Papuan. I don't ever remember seeing the big ones in Ambon, just the thinner types, but I could be wrong. Also, on a side note, how long have you lived/worked in Indonesia/Papua? And where at, exactly?
TimAnderson (author)  mindsystem5 years ago
I lived in Jayapura for a few months in 2004 and did some traveling. Java, Madura, Bali, Southern Sulawesi, Kri Island near Sorong. Where are/were you? What kinds of boats, blacksmiths, and ingenuity are you seeing?
born in Ambon and lived there (on and off) till '98 when things got heated. then lived in Jakarta for a while and then Papua for about two and a half years.. now I'm State-side for college. most of my knowledge is from older videos of the place that I saw while I was in Papua, and memories of Ambon from when I was younger.. which is why I said "I could be wrong".. anyways.. as for ingenuity..? well the Malukans make some of the best wood boats out there, or so I've read. the kids in my neighborhood always make little "spear guns" using rubber bands and broken umbrella parts. and an old military man who used to live next door had a couple spear guns like what you have pictured, but shaped more like rifles, with stocks and all... that's all I can really remember right now, but I'll ask my parents if they can remember anything as they'd be more likely to.
