But there are bronze bushes in the gearbox of a Colchester master lathe.Are just bearings, not bushes, bronze or otherwise.

Mr Honda, Mr Kawasaki, Mr Yamaha had a couple of things in common….they didn’t manufacture lathes .I get it - use the specified oil, if you want. But really, bearings are bearings, gears are gears, and lathe gears used in home workshops, and even repair workshops are not worked hard. Even if they were, it would be a good oil that beat the ability of modern engine oils.
If you don't agree fine - go take a look at anything made by Mr Honda, Mr Kawasaki, Mr Yamaha or others since the 60's....
Maybe there are (don’t recall there being but I’m not about to dig out my manual), if so engine oil is not about to harm them, to my knowledge.But there are bronze bushes in the gearbox of a Colchester master lathe.
Like I said before, your lathe, do what you like.Maybe there are (don’t recall there being but I’m not about to dig out my manual), if so engine oil is not about to harm them, to my knowledge.

Yup, been there recently with my M300. £1475 for a front spindle bearing (luckily I got a good used one somewhat cheaper) so based on that I'd spend out on the right oil - cheaper in the long run!Gamet bearings may 'just be bearings' but they are incredibly expensive
Iso 68 is what I use however I only use it as I’ve been advised that due to NZ being hotter than the UK, a thinner oil is better as the iso 32 won’t get flung around as well.We use iso 68 hydraulic oil in the machine tools we build. This is for lubrication to helical gears, worm gear sets, plain and roller bearings and also for hydrostatic bearings. I'm not saying that is what Colchester would recommend so I suggest you give them a call. They're based in Elland as Colchester Machine Tool Solutions and they should point you in the right direction.
Don't you mean a thicker oil is better in NZ?Iso 68 is what I use however I only use it as I’ve been advised that due to NZ being hotter than the UK, a thinner oil is better as the iso 32 won’t get flung around as well.
No, thinner.Don't you mean a thicker oil is better in NZ?
But thicker oil is better in warmer countries isn't it?No, thinner.
even if the manufacturers reccomendation is 50 years out of date....Wow, whole pages of absolute tosh about how people somehow know far better than the manufacturer about what (totally and utterly different) oils are better
By all means, run whatever crap you like in your lathe, but don't recommend the same crap to others and then expect no backlash!
As a rule yes, sticking with iso grade hydraulic oils most construction equipment manufacturers use iso46 in ambient temps of say -10 to30c but when the same machine is used In higher temps of say 0to40c+ they will specify iso 68 and in lower temps of say -20to20c they will almost always spec iso32 in the hydraulic system's.But thicker oil is better in warmer countries isn't it?
Oh yeah i forgot that ISO 46 had moved on so far in spec since 50 years ago... Oh waiteven if the manufacturers reccomendation is 50 years out of date....
