Ok here is my homemade coolant flood system. Its cheap and makes a simply amazing difference in feed rates and tool life.
This is on the head. Initially I just used one of those gray barb fittings from lowes but upgraded to the flexie stuff. Both work great. You can also see my DIY DRO for the z axis, ($9)
the vinyl tube ($2) runs down behind the mill to the pump in the bucket.
Heres the cheapo boat bulkhead barb ($5) through the HVAC pan. ($18)
this is looking under the table at the coolant return through the bulkhead fitting, a short section of vinyl is attached to minimize splashing ($1)
This is looking into the 5 gallon bucket that houses a magnet laying on the bottom ($1) to attract small metal pieces.
Also you can see the pumps tube coming up, just suspend the pump 1/3 of the way up to keep the metal frags away from the inlet. I used a spare aquarium pump. The cheapest at walmart will do ($12)
Scummy looking huh anyone thirsty? I ran the power cord up to a power strip that turns the pump on or off. When on you cannot see the tool cutting but the chips FLOAT up and away, fall into the pan where they sink onto the bottom of the pan. From there periodically I collect them with a magnet and dispose of them.
I hope this is clearer than my verbal explainations have been.
