Rebirth of a Denford MIRAC CNC Lathe
nrml:
A 3D printed reservoir is a great idea, but what would you use to seal it to make it water tight? Will epoxy play nicely with lubricants?
awemawson:
Acetone vapour is supposed to work for ABS. I've not tried it as a vapour but I have dipped parts in acetone. I'd imagine another approach would be to dissolve abs in acetone and make a 'wash' to seal it.
Perhaps one of the 3D printing experts can pipe up - ping Joules !

So back to the white paint problem :scratch:
It looks pretty certain that the only way to lift the cover off is to split the electrical enclosure off the back of the lathe, and gain entry from the rear. However this is by no means guaranteed. It looks that all the wiring for the enclosure enters and exits at the top right hand corner viewed looking into the enclosure. The two seem to be held together by four large cap head bolts, and the one that is visible from the lathe side is welded to the rear panel of the lathe enclosure with the nut on the electrical enclosure side. Hopefully they are all the same.
Now it certainly looks as though were the four nuts removed and the enclosures separated a bit, the electrical one could be swung through 90 degrees or so to give rear access to the lathe enclosure, which may or my not allow me to unbolt the rest of the cover that I want to lift off :scratch: It all depends on there being enough cable slack, and until I try I won't know .
BUT there is a GOTCHA :bang: All the components in the electrical enclosure are mounted on a separate inner panel (which is a common practise) and there are large holes cut in this panel to give access to the nuts, BUT the panel has slipped down and the holes no longer align - a socket or box key will not engage the nuts :bang:
Now it should be fairly easy to realign the inner panel - the machine must have been dropped a bit at one time and it's settled the panel downwards - but if I shift it my PC mounting and PC bezel will no longer fit as they are aligned with the shifted panel.
SO - to attempt separating the enclosures I'll have to very carefully mark where the inner panel now sits, shift it upwards, undo the nuts, hopefully separate the enclosures and then hopefully get the cover off and paint it, and the re-miss-align the inner panel ! What a kerfuffle :scratch:
. . . or I could do a bodge job on the paintwork - just hand rub it down, brush or roller paint it and call it done . But I don't like rollered or brushed paint work on machines, and the rusty bits really do need the attentions of a grit blaster . . . . . . decisions decisions . . . . .

Denford seem to love to make their stuff difficult to dismantle. I bet their designer used to work for Leyland or something. I had a denford lathe that I needed to get the QC gearbox off the front only to find that 3 of the four bolts are easily accessible but the fourth is down inside the headstock sump in the bed and the only way to get at it is to completely remove the headstock, for which you have to remove the motor covers, the splashback, the interlock wiring the belts the motor speed change gear and the chuck guard interlock and even the lo-volt light. All to get at one damn bolt.

Andrew I scrapped a couple of bridgeport interacts a few years ago kept just about everything apart from the carcass,I may have a lube oil reservoir lying about somewhere,if that would do the job .
