JIM - I don't think ANYONE can have just ONE welder. Dad gave me his "Will-Weld" AC buzz on welder when he bought his AC/DC Miller Thunderbolt about 1980. I still have the buzz box, I can actually lay a fairly nice bead with it. I haven't used my Miller-Matic 185 Mig in almost 10 years. I bought a Miller Dynasty TIG DX200 about 1998, but with the price of shielding gas, tungsten, welding rod, it's expensive to practice enough to get good. I bought a new water cooled torch for it, and a water cooler. SON welded some 1/4" the aluminum to make an intercooler mount for his jet ski, used all 200 amps, long welds, had to wear TWO welding gloves to hold the torch. I've got a wireless foot pedal for it too now. I'd like to get good enough to butt weld soda cans together. And I have an oxy-acetylene torch too, strictly for heating. SON bought a used Miller-Matic 200 that needed some work, and parts, it welds like a new welder, it's called a 200, but in reality, it's closer to a 300 Amp welder.I got a Hyper-Therm 40A plasma cutter too, good cutting up to 1/4" thk steel. When the price of steel went crazy about 2005 I stopped building stuff.
Was about 2004 or so I built a small flywheel K321 too. I found a Forged Alcoa aluminum rod, had the big end of the rod machined for a Clevite 77 bearing insert, the machine shop offset bored the rod to pop the piston up in the bore a bit,, more compression.. WE did some porting to the block too. Put a K361 cam in, but it's too close to the stock cam. I put the old heavy big flywheel into a K301 I had, it was crazy what a dog it became, was real slow to gain rpm, pulled alright, just slow. The K321 on the other hand gained rpm like an electric motor not hooked to anything. I was pulling my FARMALL M around the yard, I pulled off of the damp grass onto the dry concrete, shoved the throttle wide open running in 2nd gear, the fast 2nd gear in my 72, and instantly I was at 3600+ RPM, both rear wheels slipping/spinning making 8-1/2 inch wide black streaks across the concrete.
I mow with my Cub Cadet TANK LZ54 zero turn now, 27 hp Kawasaki for power. It throws clippings 10-12 feet, two swaths away from where I'm driving. I've got a couple spots in the yard where the clippings are piling up a bit. We've been lucky enough to get a tiny bit over "normal" rainfall this summer in our area, we made up a deficite of just over an inch of moisture over the past 2-3 years.
