Re: [Harp-L] Steel Reed Thickness

["Monsterharp" <Monsterharp@xxxxxxxxxxx>]

Use a peace of tapered rod. insert it gently till it stops mark it and 
measure at the mark with an outside micrometer.  If you have an assortment 
of fairly clean
drill bits you may be able to get fairly close measurement with the non 
business end. You could also try stacked point gauges from the auto store.
None of these are perfect but somewhat close.
