My best recomendation is to get a nice little grounding wrist strap from radio
shack or equivalent. See that it has a larege (maybe 10 Mega ohm) resiostor i t
n it or it might not be safe for you if you get a big shock. Also, don't touch
the pins or wires if you can avoid it. the wrist strap should connect to a
ground. It can be a pipe or a large metal object like a shelf ihat's all you
have. I actual;y ran a wire through the house from my 2nd floor room to the
pipes in the basement. Very nice. I had a metal pag and strap. the pad was ont
he floor so I was always grounded. I don't recomend that over the strap thpugh.
It works, but could be dangerous without a HIGH resistor. The wrist strap is my recomendation
Prdon the poor typing, nut my built in trackpaf on my computer died so editing
is a pain. I haeve an external one, bu it;s too sensitive and it bounces
areound, I'm salos sitting in a car seat turned a rolling chair. comfortable as
heck, but not complete, so it is VERY abnormaly low. My chin is 4 inches over
the computer desk! hehe! (:
I be a normal height when i borrow my mom's drill, so i can finish the
underframe. I DON'T recomend screwing 2.5 inch screws into wook by hand without
predrilling1 OUCH! that made my wrists tired!
I'll be posting my plans for the chair to my web page as well. The plans will be
specific to thr 1984 pontiac sunbird bucket seats! Oh, so soft andplush! I'm
going to hit send and lean back with the chair on FULL back tilt@ Hehehehe! (:
