Turps is cheaper than kero at Bunnings. Has anyone tried it as a lube?

Never even thought to try it, but it has it's own odour.

Just a heads up that odourless kero has the same OHS issues including exposure limits etc as ordinary kero. The low odour might in some situations even make it more dangerous than normal kero as the odour of ordinary kero warns folks that it might be time to do something about vapour build up. If someone experiences ill effects due to the basic hydrocarbon components then they might wonder why if the can't smell much and they are feeling crook.
Despite this I will be using it as soon as I use up the remainder of what I collected from mum and Dad's shed when mum moved into my sisters place. There were 4 bottles of regular Kero not to mention other flammables and various (many poisonous) garden chemicals. I took a van load to the waste transfer station and the attendant thought I was clearing out a nursery.

Hi Guys,
I took about 20 Ltr of old engine oil to the council dump the other day ! Talk about "Jobs Worth"...
I had to tip it into a large plastic container, which had a lidded hole on top with a grill across it. The container was as tall as I am, I had to stand on the bunding to reach the fill hole.
Now the waste oil that I had was in a 25 Ltr container. I simply couldn't lift the container that high, so I asked one of the attendants if he would give me a hand. "No" was the curt reply, "you have to put it into smaller containers" and off he walked, down between two skips and then lit up a fag !!!
I was able to rescue a 5 Ltr plastic bucket from some chap that was disposing of it, and used that to get my old oil into the tank. I disposed of both containers in one of the skips. I don't know if it was the right skip or not, at this point I didn't care.
I do know that an incineration plant was built not too far away, one of the neighbours suggested they might have taken the old oil.Best Regards:
Baron J.

4140, WD-40 and a pair of fish tins.
This morning I made a replacement M4 thumbscrew for my daughter's piercing saw. The 4140 I used knurled nicely with, tooth brush applied only to the top wheel, WD-40. Slightly coarser pitch than the original but close enough to keep everyone happy.
Certainly nowhere near the mess created with kero and a parts cleaning brush!

One of the things I find contributes to a successful knurl is not winding in too much. Empirically, I find that winding the knurls in around half the pitch seems to give a sharp knurl. Less and it is not fully formed, more and it risks distorting the knurl (for scissor type knurl, total movement would be double that).

Anorak Bob,
You seem to be using the knurling tool on a rear tool post. Is that so you get a better view or is there some other reason?

I can't stand the smell of kero either and use WD40 for knurling, much better than the slurry you get when using oil.
