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?
Just noticed it needs an oily rag rubbing over it, probably the second time its been out of the box for about 20 years
I suppose I should consider making a bit of cash and selling mine, but to be honest, I dont think they are worth much these days. Guess Ill follow Tommy and give em a good clean, then put them back again

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...
What are you going to measure? you lost me after Mitutoyo micrometers, is this for rebuilding engines or checking tolerances ? slip gauges?drrrr my brain's froze,
