First consider the speed of the vibration. If it is wheel or axle related it
will be a slow vibration. If it is driveline it will be three to four times

When I did mine I didn't have my lathe. Used my mill and rotary table and
did lots of passes, round and round. Is really smooth. Now I have a nice
lathe, could easily do an 8 inch chunk of aluminum. As far as the coupler,
taper locks are nice but instead I did a simple coupler, .0015 undersize.

Back to inverters. Be careful buying non UL Asian inverters. A lot of them
do not have a neutral to ground tie. You will find instead that the ground
prong or green wire is actually tied to the center tap of the output and
that NEUTRAL is 60

I would suspect that sunlight on the display raises the current draw of the
display. This current draw is on the 5 volt regulator of the entire meter.
Being an inexpensive meter the 5 volt regulator is also the reference
voltage for the meter. Current goes up, reference voltage goes down.
I am not so sure it would be a commutator bar. If it were you should have
worn brushes down by now. My guess would be more like a winding broke loose
and as rpms increase it moves out to hit the field shoes. If it were me I
would disassemble the motor and pull out the armature. You will see

What gives any indication that they can't tow as well as any other car or for

To be simple it is not all about just the fact that all cells get the same

Good point. It is very hard to hold onto metal above 70degC. I would bet the
max temp to be much higher than that. Also if you are concerned why not duct
air to it? In days way passed, we used 3" ducting on the cars we raced to
cool the brakes. It is very affective.

very small. Might work?

I purchased 7,500 kw (168 x 45) for about $1,200.00 through EBay. Supplied
the end plates and water hoses too. I think next time I will just buy a
salvage Volt and sell off the rest, then scrap it.

Yes, $46,000 is a lot of money but don't forget about the savings in fuel
dollars over say 10 years or maybe 100,000 mles. Is it maybe $15,000.00.
