I was planning to use a windshield washer, in conjunction
with a '555' timer circuit to give me adjustable spurts of
coolant, instead of flooding, 'cause, some jobs, I have a
wet-vac that I use to suck up chips as they're being cut...
getting the swarf outa there keeps the finish better, and
extends the life of the cutting edge. as far as being O.T.,
I plan on using my M07 relay output for the intermittent,
and M08 for continuous, with M09 shutting off both relays.

This may get axed as off topic - and if so I apologize
and would
welcome people to respond off list, its just that I know
of no other
group that would have good ideas.
When I'm machining manually, I don't mind so much using
the squirt
bottle for coolant supply. However, I'm not so sure
that's going to
cut it when I get the CNC running so I wanted to setup an
easily
controlled flood coolant system (but cheap - since I'm
good like
that). I was going to try building one using a
windshield washer
pump. You can basically get them next to free (if not
free) at a
junkyard and they're easily controlled with a dc relay
off the
parallel port. Has anybody tried this? Anybody know any
good
reasons why this may not work? The only concern I have
is duty
cycle, but if another pump is practically free, maybe its
not an
issue. THoughts?
