That's very interesting! I lived in Peru 4 a year doing missionary work and have also visited Indonesia and Mexico so I understand a little bit about what you are talking about.Hi All,
It's been a while since I posted here. I didn't have the space or resources to tackle anything interesting and after a while I wasn't even lurking. It looks like that's about to change.
I moved to the Philippines a while back. In the coming year I'll be tackling a project that requires a substantial amount of welding on 4mm hot rolled mild steel plate. Running mains power to the work site just isn't in the budget. Neither is a new engine driven welder. Large portions of the country are, "off grid". There are *NO* inexpensive broken welders. When they break, they get repaired and/or sold to somebody who will fix them. Used machines sell at not much of a discount from new price.
I'm going to be stateside from Feb. through June of the coming year. Shipping a commercially built rig, or even the generator head off of one, back to the Philippines would drive the price higher than buying new locally. A home built welder head based on a heavy duty alternator should be under my economy shipping limit (50 lbs.) and labeling it "scrap auto parts" should get me under the minimum value for assessing import duties.
At this point I'm sort of pre-scrounging parts. I've got a 1 liter three cylinder including computer and wiring harness out of a Chevy Geo lined up as a power source for the trial and error phase. I've got a cheap Arduino programmable controller with four stepper motor modules. Since I'll be using the controller to regulate field current and engine speed, I'll probably be better off starting with a blown alternator. It would be nice if it had good bearings and winding's but I can fix that if I have to.
Does anyone have suggestions regarding the source for a core?
Any ideas on where I might scavenge heavy gauge magnet wire for a choke coil? Any (constructive) criticism?
Do you mind telling us what your project is, and why you moved to the Phillipines?
