Need a Longer Thickness Caliper

[Mike Turner]

I love these calipers from Lee Valley but I sometimes need them to be longer. Anyone have a good idea how to make something like them longer? I make flutes and I bore the long hole for the flute sound chamber.Occasionally one will drift a little and if I know this I can allow more wood to be left there when finish turning it...just maybe not turning the flute as thin. Anyhow any ideas would be appreciated . I have the longer set. Thanks in advance for any ideas !!!!

I ran across this, don't know if it will help you though: http://www.turnedwood.com/tools&jigs.html#Caliper

The base page is all about his jigs, that link goes directly to the calipers. It's a few pictures and discussions on how he makes and calibrates them.
