Measuring a reamer?

[BP1]

I am picking up a reamer from a fella that has lost the specs to the reamer.How does one go about measuring the neck and freebore thanks for any help?

Send it to the reamer maker and ask them to check it for you.

If you have someone in a machine shop that has access to an optical comparator, they can tell you exactly what you have.

Most reamers have that info on them....,

Most reamers have that info on them....,

I have 225 reamers from all of the various manufacturers and most do not have the throat and freebore information stenciled on them. The exceptions are the 'Match' reamers which I have called out the measurements for and a handful of standards such as the .308 Palma 95, 6PPC variants and similar competition reamers. All the rest have no information,not even a print number in many cases.

As detailed above, find an optical comparator, send it to the reamer company or try to 'get close' with a set of calipers (not recommended). If you need precision as with neck clearance on a tight neck chamber, get someone to lend a hand with an optical comparator to get it right.

Regards.

Measuring a reamer is very hard to do, we use 100X comparators and watch stack-able tolerances. You have to be very careful because a good micrometer will ding the flutes and that's the end of a good finish . The only way to really get the correct circumference size it will cut is by sending it in and having us do it for you , i will measure any make reamer for free . just send it in to me, thanks Dave

Will you stencil the FB and NK measurements on the PTG reamers that are not noted?
