I'd imagine that we have the japanese version of waterstones because their coarse natural stones stink. Yes, I have them. Both types. when you work wiht a good norton crystolon and india and go up from there in fineness if needed, you'll wonder why anyone ever needed waterstones in the first place (aside from a big format that's easy to use with guides). Nothing made in the world of japanese stones will cut consistently with a fresh crystolon in oil (fresh is more friable) simply because the coarse stones are the same thing as crystolon in japan, but water is an unsuitable carrier. They're generally faster than coarse diamond stones and more uniform at a given grit level, and won't care about soft metal (where as soft metal will pull diamonds off of electroplate).Jacob":xelj5191 said:I've used waterstones and diamond plates for nearly forty years without any problem. Water stones? Why critcise something you've never used, anyway? Why even bother to comment on them/................The impression I got was that they endlessly need flattening and they are short lived. Also they involve water which causes rust and may be incompatible with woodwork itself, on site or on work bench. Are you sure you've been using them for 40 years I thought they were a relatively recent enthusiasm? Ditto diamond stones - 40 years ago they'd have cost a bomb.
Yes. I was there 50 odd years ago knocking around with woodworkers and other crafts people. 60 years if you count school woodwork. Norton (or other brand) double sided oil stone was near universal standard. Sharpening jigs were there but not common. Japanese waterstones were unknown.Rich C":374ytb9v said:Do you have any evidence that everybody used them and didn't use water stones? Or is "everybody" in this context actually just "you"?
Your luck is better than mine, but in fairness, I didn't always end a shop session by wiping my tools. I live in an area that's dry in the winter, but above 63% relative humidity in the summer (especially because my shop is halfway underground, and thus cooler than the already humid outside air - increasing the RH).phil.p":jv9eikt1 said:There's little wrong with oilstones, I just prefer water stones. If you use them a little carefully they don't hollow all that quickly and as Pete said - I'd sooner have a drop of water on my hands, tools or wood than a drop of oil. I have never had a spot of rust on anything.
Anyway I promised myself I wouldn't get involved in this thread as it's always the same, just going around in circles.
In the US, it's unusually for temperatures to be low enough to get RH that high. There's someone from memphis who peruses the forums who claimed 95 degrees and 90% humidity (which isn't actually possible - a 75 degree F dewpoint, which makes for extremely uncomfortable hand woodworking - results in an RH of about 50%. The 50% figure makes it sound tolerable, but it's not. If the temperture drops to 80, the dewpoint generally drops, too, unless it's raining or foggy here).phil.p":1zujojiq said:Where I am atm the r.h. is 81%, which is quite low. Most days it's higher.
Indeed. I went bonkers over sharpening and getting as lazy as possible about it during the course of switching over to hand woodwork. I sometimes forget that quite a lot of the woodworking population doesn't finish with planes, nor do they do any rough work with planes, and they may sharpen something once every few shop sessions whereas I may work in the shop for two hours and sharpen something in heavy use every 20 minutes (more often if chopping with chisels).Lons":36biwsdu said:As a hobby woodworker I'm not doing peacework so the alleged few minutes extra it takes is of absolutely no concern to me and possibly applies to a majority of users these days.
I'd imagine that india is terrible as far as dewpoint and humidity, but that sign was a bit of a ruse. It's suggesting a dewpoint that is 7 degrees F above the highest ever recorded anywhere on earth (95F is the highest ever recorded, or 35C)SammyQ":1g2x5nev said:Coming back from Agra to Delhi at midnight, motorway gantry sign said:

Daytime temps were 48°C or so and in the monsoon, we had small (1m across) clouds drift in through the open doorway of the hill station school I was working with. You wouldn't believe it unless you saw it. One colleague thought the local cook was spiking our meals with extra "herbs" ( marijuana is as common there as nettles are here).
Surface rust was everywhere as you might expect and the rickshaws ( tuk-tuks) structural integrity had to be carefully weighed up before embarking(!!). Yes, I know, thread drift, sorry.
