How to prevent rust in measurement equipment?
PekkaNF:
I have bought, begged, ordered some of the aforementioned raw materials.
Let's see what comes up.
1) For this Lew-Oil, in which order and method stuff should be mixed? All together?
2) I tried to mix liquid parafin and IPA, looks like there has to be lot of IPA and a little of parafin. Very mild scent, very little residue and cleans well. Will need a little balancing.
Any other tried recepies?
Some of the stuff is a little suspect and hard to find. I'm baffled of the camphor. Is't it sort of resin? Anyway, I found camphor oil, I suspect it is only usefull for scent, but got it included on the same P&P than oil of wintergreen, maybe I find some use for it.

My approach is to use syringes to extract (reasonably) exact amount of the liquids (oil of wintergreen and 10 weight machine oil) and squirt them in to a ground glass seal bottle (approximately 1 cup or) 375 cc. I then extract (about 3 cc) of the fluid and squirt that into my cotton stoppered prescription bottle. That is then "set" into a (usually corner) space that holds it when the tightly fitting case is closed.
PekkaNF:
Thank you much.
I have had a lopt of work and other activity to keep me bussy, I have been collecting some household chemicals. Few more coming up and then I can start to experiment a little.
I tried a little of my almost favorite cleaning agens: Liquid parafin (baby oil) and IPA. They don't mix at 50% concentration, sort of emulsion is formed, but that seems to clean and lubricate easily.
When I'll get the oil of wintergreen, I'll try Lew's recepie.

And yet my machines and measuring equipment in the main workshop don't rust. Why ?
One could argue your temperatures are back to front (for tools) not personel as the ambient temperature drops (at night) the water condenses from the air onto colder surfaces.
In the day (typically warmer) the moisture is absorbed into the air.
Having said all the above the thermal masses will be out of step with the surrounding temperatures.
What does anyone think?
... I heat the workshop - daytime 18 deg C and 8 deg C over night. Works for me :ddb:

Use gloves with the above, especially with wintergreen as it contains methyl salicylate, which contains basically aspirin. This can be absorbed through the skin. 5 ml of methyl salicylate contains approximately 6 g of salicylate which is equivalent to almost twenty 300 mg tablets of aspirin. Although the amount you will be using is negligible, if you have a blood disorder or ulcers it is possible that it will irritate you or worse.
Camphor is used in moth balls for clothes in wardrobes. It deters moths form laying their larvae and making holes in your cloths.
You could just use the mothballs! :coffee:
