I once had a similar problem with drives tripping out ...it turned out to be lack of oil on the slides. The machine had been sat for a long time before I got it and the oil had solidified in the oil tank blocking the lube filter..it didnt show a low oil alarm as the oil tank was always full but no oil was getting pumped round the machine!!

Well I >> MAY << have solved the "coolant splashing on the camera" syndrome :ddb:

This little beauty fell in my lap curtsy of eBay the other day

awemawson:
It has a 10" spinning disk and is actually designed to give a view port into a CNC machine that is awash with coolant. I never realised 'the proper deal' existed.

All the essential bits seem to be there (still in transit so not got my sticky fingers on it). It would originally have had a fancy mounting that fixes on with a ring of 3M VHB extra sticky tape, with a large 'o'ring kept squashed by the adhesion of the tape ( I assume that the tape is thinner than the 'o' ring ) and for initial mounting is sucked on with a vacuum. All the details are here:

No doubt I can fabricate something, but my bigger issue is its thickness. The lathe door slides and there is very little clearance between the fixed panel and the sliding door. One solution is to cut a hole in the door pane so that it is practically flush, but the door pane is re-inforced glass laminate sandwich. Until I physically get it I'm not sure which way to fix it - I suppose I could replace the door glass with a thick polycarbonate and pierce that.

Also used to be known as Kent Screens although the company seems to have folded.

Gert used to have one fitted to her trawler :clap:

I reckon you can make a simple one by breaking the blades off a computer fan and glueing a clean screen on.

awemawson:
Yes that was going to be my approach until I came across this one. I reckon that you'd have to regard the fan motor as disposable as fairly quickly the water content of the coolant would see it off.

Yesterday I sorted out the bin that the "parts catcher" dumps finished parts into. It's a stainless steel open box with a perforated base to allow coolant to flow out. It was filling with coolant and seemed to have been mounted on some fibre board which was blocking the perforations. WRONG - that 'fibre board' was densely packed fine brass and steel swarf bonded into a solid chunk. Dismantling it and scraping off as much as possible I ended up sand blasting both sides of the perforated base - got the faces of the perforated sheet nice and clean but the holes mainly remained blocked. Ended up pushing a 2mm drill through almost every one and there are hundreds :bang: Anyway nice and clean now and the coolant drains away from it nicely - I'm sure my wrist will eventually recover :ddb:
