Cooling a water cooled spindle, without pipes everywhere & huge water tanks/buckets!

Ok ...water pumps.

it seems the plastic tubing spec for the water cooled spindle is 8mm OD & 5mm ID ...but most of the water pumps on Ebay seem to have nothing of the sort...so is everyone using water pumps with reducers/adapters?

If you are only cutting/drilling pcb and other soft materials. do you even need to bother with cooling? I have been running my wc spindle without cooling for about 10 years now and have never felt the spindle get hotter than hand warm. Obviously if I was doing very long runs cutting hard materials I would keep checking it did not overheat, but to date I have never had need to water cool. G.

Dunno...never had one. I just assumed the fact that they were called water cooled spindles meant you had to water cool 'em!

I'll probably be running jobs for about 45mins to 1 hour max ....but for the sake of a pump & a bucket I think I'd rather err on the side of caution (my machine already has the plastic tubing installed into its loom, so I only need to add a pump & I'm off to the races - but like I say...which pump, which outlets!)

My pump has 8mm connections and I was assuming/hoping that the 6mm tubing would stretch enough to go on...
