RWTF, I have some small reels of mig wire here which I use quite often, it's seems to do a good job most of the time as you say, just a case of cutting lengths and cleaning off the copper with scotchbrite and a quick wipe with Mek solvent .
I've noticed a few old parts (mainly from ancient air guns and the odd cast part) aren't so easy to weld small areas as the wire and other grade steel rods I have don't seem to flow as well and there's a temptation to lean on the pedal which gets parts a little too hot, it's probably not an issue with most jobs but I'd like to try the Nickel Steel rods as people say they flow in really well.
Perhaps i've just had a few 'dirty' castings/forged parts in a row but I'd like to try some other rods which may make life easier and still allow parts to be blacked or blued.
We have to think in stereo over here, millimeters and the metric stuff can be easy to work out sums but I still use feet and inches, pounds and ounces because they're easier to divide.
Imperial threads, good once you have a grip of what's out there, I play with Brit motorbikes so had to adapt to all the weird and wonderful combinations of thread sizes, often different on one end of a stud to the other.
It's all good fun though
