Re: Angle Iron Ways

Graham,
It might be possible to very easily profile long ways. The electrode
holder doesn't need to be very rigid as it hovers above, but does
not touch, the part. I wonder if you could mount the electrode (Z
axis) on ways made of stretched wire/cable parallel to and above the
part. You would hold the work and pull the anode, with a third
cable, down the way cables over the part. The feed cable could be
pulled by a stepper/capstan. The tank could be a plastic rain
gutter. Power could be run down the cables which are positioned
above the salt bath. The down feed could be manually adjusted at the
end of each pass. I guess the feed rate could be adjusted based on
current. I have a multi meter that talks RS-232 which Mach should be
able to read.

Sounds way to simple to be do-able.

finishing tiling the shop instead of reading about ECM.
