I don’t want to intrude upon Bill Phinn’s cycle thread discussion … but I would like to share this with fellow microscopists and anyone else with a serious interest in thread-forms and/or Imperial/Metric approximations.

It should be self-explanatory, so there may be no need for replies or discussion

… that’s fine by me.

Edit: __ incidentally, it’s interesting to note that Japanese standards are available at relatively modest prices.

Apparently there is free on-line access to British Standards On Line via some libraries, but the page on BSOL describing which ones has been taken down.
You used to be able to access via a Northern Ireland library card, but I think that was withdrawn last November.
Unfortunately my Derbyshire card doesn’t provide access as they haven’t bought an account for cost saving reasons.
Lancashire still claims to, but I don’t have a card there; do we have any Lancastrian members?
I think one or two libraries do have access, but only from their own buildings, and some universities allow access, but via their own intranets.
