I've been going to get a gas setup with the portable tanks. I used to be
okay but it's been a long time. Gas is more versatile and works anywhere
you can drag the tanks but the inexpensive point and shoot wire machines
do make life easy over stick welding.

I don't know if the new paints and HVLP guns are any better but the guys
shooting lacquer had half a buzz on to start with. The shooting isn't
bad but the prep, prep, and more prep followed by sand, sand, and more
sand and then buff and buff gets to me. I can only massage the same car
so many times before I'm utterly bored.

I guess that's why he is repairing cars instead of designing them. He
should be introduced to the bean counters in Detroit. They'll explain why
that bolt is there because if the designers couldn't explain it to the bean
counters, it wouldn't be there.

Same here. Any car of mine that needed an engine wasn't worth putting an
engine in. Older cars were not made to last and that was true for every
part of that car. Even things like seats and headliners were shot by the
time the engine was shot. My current truck has 240,000 miles on it and the
engine is one of a number of parts that shows nearly no sign of going
anytime soon. The parts that have been repaired often were not repaired
right so some have needed repairing more than once, but otherwise the truck
is very sound.

Evidently you never owned a Buick or Olds with the 3.8 engine from the
early 80's. I know of many being rebuilt/replaced. I had the engine
replaced on my '83 Cutlass and drove it until the next one died. The
car had 130,00+ miles. Not sure how many as the odometer stopped
working. I was determined to drive it until it does. Left work one
day, started the car, drove 3 feet and it died. Took the company pickup
home and stopped at a car dealer on the way and bought another car.

Charity shop, sold as seen, acquisition as potentially 16x optical zoom
with gyro lens servo stabilisation.
Works all functions but zoom only out to about x4, above that then a
gear tooth jumping noise , then "zoom error" and have to power down.
Assuming it was dropped or something , when the lens was extended, what
will i likely find inside. Good SM with dismantling out there.
Stripped rack?, something bent?, no internal noses of broken bits.
Never dealt with one of these complex barrel in barrel in barrel lenses
, but am willing to give it a go.

Capacitance meter. Measure the capacitance to ground for each lead at
both ends of the cable. The ratio of capcitances will give you the
location of the break. For example, if you get 15PF at one end and
40PF at the other on a 36 inch long cable, the break is at:
15 / (15+40) * 36 = 9.8 inches

Yeah, but that's too easy and not any fun. You don't learn anything
by simply replacing it.
