    Ok, cleaned up a bit, removed the reference table, mounted the main table and did a quick test fit of the Z Axis bottom part.

    The naked machine


    Some bits on it



    Z axis, ballscrew is just 'hanging' onto the overhang, not mounted. The Z axis needs some of the holes to be drilled all the way through and I need to find the location of the bottom carts. I did not have the measurement at hand when I machined the holes on the larger mill. As these are not threaded, I have a bit of margin for error.

    I have to say I think your 3d printer might be a bit over engineered ;)

    That is a work of art ;)

    Can anyone recommend me a nice simple watercooling solution for the 4KW Spindle.

    I had considered something like:-

    6mm fish tank tubing (size to be confirmed)
    Small fish tank pump
    Some form of container that allows the heat to leave the cooling cylinder.

    Ive seen some elegant solutions that use a CPU type cooler for a closed loop system, I am all ears ...

    Thanks

    Something like this (With fans stuck on it) would work well

    Simply splice the radiator into the return.

    Thanks. Certainly an option.

    I like this too, not sure how adequate it would be on a 4KW Spindle.

    I would worry that's underpowered but I also read you don't need a lot as the spindle are pretty efficient and don't make much waste heat. I'm going to use a 2.2kw spindle for maybe up to 10 hours per day 5 days a week I'm hoping a 200l barrel will be enough on it's own but if need be I'll use one of those heat exchangers I linked to I can get them much cheaper than that link from scrap yard friend so if you ever want one just PM me and I'll sort it out.

    I'm only going to use a maxijet pump (Aquarium style) but it'll be fine as long as the head height is enough (Which it is 2m's) but will need to reduce it for the spindle (13mm standard hose pipe on pump)

    The heat exchangers are 25mm pipe compatible

    These fans are pretty quiet and pump a lot of air also cheap!

    Just drill some holes in the fan casing and cable tie it to the radiator it's probably best the blow through the radiator but even if you suck I bet it would work great.

    You can fit 2 5" on the heat exchangers but 1 6" would be fine on it's own.

    It seems most get away with 20 litres or less. Your 200 will be a massive overkill.

    Ha ha ha now I take that as compliment from the man who's building his cnc machine from concrete and called it after either a norse god with a big hammer or the god of war lol.

    I have the space and the waterbutt so I figured why not ;)
