I'd like to get some measuring equipment for using on bike engines. There's a lot of old used Mitutoyo micrometers and the likes for sale on ebay. My question for anyone who's experienced using measuring equipment is, would it be a waste of money buying old measuring equipment since you don't know how well it's been looked after or does good quality measuring equipment generally stay in spec? I was thinking about buying an old set of micrometers and then getting them checked with slip gauges. Is that a waste of money? Do you need new ones for checking engines?
Like others, I still have my old Micrometers, Verniers etc from 30 yrs ago but I look after them. As said by Agricola, the micrometer will be ok if it hasn't been used as a G clamp...like wise the verniers will be ok as long as them haven't been used as a crowbar. The problem is you won't know how 2nd hand units have been used. Find an old boy who's having a clear out and you should be fine. Apart from that I wouldn't buy 2nd's to use as a true measurement. Just my 2p...

I'll keep a look out for a well cared for set. Engineers generally look after their equipment so with a bit of patience I should be able to find a good set.
