The Dirtiest jobs in history

Tony Robinson ran a series on the Dirtiest Jobs in History where he supposedly performed some of these nasty jobs himself.
Well I reckon I've found another one for him ! Cleaning out the soluble oil tanks on my J&S 1300 cylindrical Grinder and my J&S 540 surface grinder. Having to drain them in preparation for moving, of course it made sense to go the extra mile and clean them out - yuck - vile clots of nasty submarine something or others that possibly came out of Dracula's bowels !
Only got the Bridgeport manual mill, the Brideport Interact CNC mill, and the power hacksaw to do. Then I need to decide if I should drain the hydraulic oils from the grinders.

Yeah had all that on my 540 .
don't know, maybe a good idea to put a magnet in a cup below the oil return .
and this one I like .........add 2-3 cc of 100 percent pure citronella oil to the new oil .
this is the stuff that they put in 3-in-1 oil to make it smell nice
it's about 5.50 on ebay for 100 ml of it .
this will give the workshop that precision smell of 3-in-1
Could add it to the Bridgeport cup oil as well ... such a tiny quantity will not do harm and 100 ml will last for years ...has the added benefit of ...it is also an insect repellent .
all the best....mark

Do so!
If the grinders have external tanks like the one on my 1400, they are unstable when lifted and are very likely to dump a dozen gallons of oil each on the ground.
You can treat the move as an opportunity to decant the oil into a collection of drums and clean out the crud that will be in the tanks. Since the filter is on the pump outlet, the tanks fill with most of the unpleasantness that the oil washes out of the grinder. Then you can strain the oil back into the tanks at the other end.
Of course, if they've got internal tanks and the oil has never got crudded up, then ignore the above and save a day of unpleasantness :-)

Mark, the hydraulic oil tanks are internal assemblies - I reckon I'll have to pump the oil into a cask. I'm tempted to replace the coolant with straight oil when finally the workshop gets re-instated, but that is likely to be at least a year as I have to re-roof the barn that will form the workshop, put down a new concrete slab with the novel feature of all being at the same level unlike the exisiting one which is all over the place, and it might be quite a good idea to put doors on the gaping hole where they should be - it's only a hole of about 25 foot wide by 12 tall - slightly excessive ventilation I reckon <G> - oh and there's that wall that's canted over at about 5 degrees that needs knocking down and re-building. In all not just a weekend's work !

If you want some straight oil Let me know as I get some in 5 gallon drums and 45's It been used in some very expensive lathes in showroom conditions and then drained out when the machine is shipped. The nice H&S men say they can't keep oil on their premises so it's a pain but I have to go up and collect it all for free..........
Worst bit is it's not near any of my customers so I have to make a special trip and that cost me at least 1/2 a gallon of diesel..........................
BTW I have set of heavy duty machine skates if you need them, take 7 ton per skate. -- Regards,

John,
"It would be if you stopped harping on about it and got on with it <g> " Well the SOLD sign is up, but it seems that means very little in todays housing market !
The minute I arrive at the new place I'd like a 45 gall drum or maybe two of that straight oil please ! I better not have it here as I'm already increasing and not decreasing the pile. I took delivery today of a 1 ton Blacksmiths Power Hammer - couldn't let it pass as they are like rocking horse poo - poor old Pallet Line chap couldn't manage to get it onto the tail lift of his truck - eventually used my 3 ton chain lift to pull it <G>

One warning - citronella oil is at least mildly toxic, which is probably why insects don't like it.
The main ingredient of citronella oil, citral*, probably isn't significantly toxic though - it occurs in lemons and other citrus fruits, and is also the main ingredient of lemongrass oil, but it doesn't seem to repel insects much. I conjecture that something else in citronella oil, perhaps methyleugenol, does the insect repulsion, but can't quote any research to substantiate that conjecture.
Lemongrass (oil) has been used for years in Thai etc cookery, and seems to have no bad effects, at least in the quantities you might be exposed to by adding it to soluble machine oil. It might be better for adding to soluble oil from a smell point of view, although it doesn't deter insects much. It's usually about the same price as citronella oil.
If you want to repel insects, try neem tree oil products (caveat - one of the biggest UK importers of these is a close friend of mine, but we have no business connections).
Actually a mixture of neem and lemongrass oils would smell nice, and nicely deter both insects and the growth of bacteria in the oil - I haven't tried it, but in theory it seems like a really good idea.

God only knows what was living in my coolant tank but whatever it was came out one day, got the H&S guy in a half nelson and disappeared back into the tank.
This is brilliant news because besides the demise of the H&S guy every one knows nothing lives on these guys so now clear coolant tank, just throw the odd tub of Denenone in it as it's the friendly bacteria or so the tube says.................... -- Regards,
