hi to all
i hope some of your guys can helpme on this:
just about a hour I acquired two micrometers, i bought them because i believe that they are Mitutoyos micrometers, any way i got the smaller (0-25) for +/- US$ 8 and the bigger (50-75) for $10 8), they are used condition, very dusty and a with little of rust.
the lettering of the brand are lost because of the previous use
besides of that, they are in very good shape, sliding smoothly, just because of rust, long time no use or dust, rotating the thimble is a little tight... and if i want to rotate the thimble with the rachet, is has to be very slow, in other way the rachet star to doing clack clack clack (i dont know how to describe that jaja but you catch me the idea)
this just happens with the bigger one, the smaller are fine
and now i want to ask for a hint for how to get this old micrometers in shape, need to disarm, clean, lubricate, and reassemble..
if they are mitutoyos for real, i don´t want to make some mistake in the process of rerestoration that can compromise the acuracy...
well, here are a picture:
here are a the reference:
still very happy with this couple, i realy like the old tooling and machine, just like the old valve amplifiers and radios. ;D
thanks in advance
Saludos!
