507 Mechanical Movements PDF: another great mechanism resource

507 Mechanical Movements

Not too long ago I told you about three great mechanism references, one of which was the not-so-cheap Mechanical Devices Sourcebook.

Well times are tough, and I've been reminded of the Sourcebook's Grand-daddy: 507 Mechanical Movements.

The link is a free PDF (507 has long since crawled out from under copyright protection) and there is no sign-up or anything like that.

So go ahead and stash it in that "resources" folder we both know you have. 😉
