|Digital Vernier Calipers|
Caution! When using the steel calipers,
be careful not to scratch your blank.
Carefully close the ends onto the blank
and don't run the calipers down to the
blank to find your measurement.
If the calipers are not your thing, I would highly recommend at least the tried-n-true 'Tip Top Gauge'. This is an easy, inexpensive tool that do 90% of your rod building work.
The Tip Top gauge will also measure inside dimensions such as winding checks and hosels. This is basically a 'Go-NoGo' gauge and we have one of these by our order processing area. It's quick and if you drop it, it won't get tweaked like the dial calipers. Good quality dial calipers will range from $30 to $100. The Tip Top gauge is less the $5.
