Srimech.comSrimech.comIt's often difficult to find parts for hobbyist model making or small scale enginering. Here's a list of the best sources I've found for parts while making various projects. Unless otherwise stated, all these companies will accept small orders without unreasonable penalties and take payment by credit/debit card.
This is a UK-specific list; these companies won't necessarily be appropriate in other countries. Some of these are more regional and only appropriate if you want to pick something up locally.
I do not generally endorse any of these companies, I've just found them useful for the specific parts mentioned. If you find anything out of date, please let me know at jim-suppliers@mode7.co.uk.
