Reply To: Questions about digital calipers

[Buccaneer]

This is the $40 one off Amazon I bought last year.

While it reads accurate,
it’s hard to get an accurate reading on a piece in my lathe, as when you
slide it off, the reading changes, when you try to lock the caliper
and remove it.
That said, it would be plenty good to measure seal sizes, bores, etc., anything
you can read while the caliper is in place.
I use mine a lot for scribing preset distances when laying out parts to work on.

While working on the lathe, I find myself using a quality veneer calipers
I’ve had since 1977, or my dad’s old Craftsman micrometers.
Harder to read with my tired eyes, but accurate.

Prepare to be boarded!
