    I know it's been discussed here before, but my searching has not found it. I have Nathans chiller, but I'm looking for the set-up on the other end. What kind of pump are you using for the water and how are you connecting everything. I would like to make the chiller water lines quick disconnect, but my local hardware store doesn't have anything like that. Photos of your set-up would be great.
    Thanks in advance.

    Fish pond pump from Home Depot, hose they sell with it, screw hose clamps and the infamous Homer bucket work for me. I just treat the chiller and hoses as a semi permanent unit and disconnect from the pump if I need to. Make sure you get the more powerful one.

    Thread bump for interest in Nathan's fluid cooled platen as well. That vertical grind setup is genius "think outside the box" ingenuity at it's finest!

    push-to-connect fittings and tubing work well for a simple quick disconnect.

    One important tip. Keep the water in your supply bucket clean as the chiller can get a little clogged of you have grinder dust in your bucket. For sure do NOT use your slack bucket as a water supply.:D

    Hydraulic fittings that are brass will work. They are used in the carpet cleaning industry and when you disconnect they won't leak. Parker makes these fittings and couplers.

    I use a cheap aquarium pump that lives in a Home Depot bucket and run lines to and from through holes drilled in a tight lid that are exactly the same diameter as the tubing so no contaminants get in. No charge for the run on sentence. :D

    Now you tell me :D
    I was using the slack bucket for my water supply and the pump got clogged up and the platen had got a little warm by time I noticed.

    Sticking with my grinders rat rod theme, for hoses I am using the hose off an old busted compression gauge and a piece of surgical tubing for the other.

    I am on my second pump ( I guess if I start keeping it in clean water ??? :p ) first one wasnt strong as I would have liked. I think my current pump is around 315 gph and that seems to work good.
