Hi to all

Lets talk about a dip or spin coater, any of you heart of it !!
That are machines even aesy to make,

dip-
as it say's dips the cu clad board in a tank and pulls it slowly out
to make a even layer on (i try't one,it works great)
its real easy to make with a slow turning motor and eventualy some
simple plastic gears travel time i mesured was ab. 30cm/min
Have somewere a drawing from it.

spin-
Heck lets take a fast spinning motor mount a plate on it (similar as
a grammophon player) i build me first 12 years ago from an old 5¾
floppy drive

BTW. I prefer the dip system it covers both sides the same time and
the drilled holes are also covered.
