No doubt chamber reaming to deep will make every gunsmith sick. The attached photo is a new tool coming out called the Lambeth/Kiff Micrometer Adjustable Reamer Stop.,Patent Pending) In short this is a add on device that controls the depth a Reamer can cut. It uses the reamer itself as the micrometer pinion and the barrel tendon face as the anvil. It does not matter where the tail stock or carriage is located, it measures off the reamer. It works with a floating reamer holder too. These new Micrometer Reamer stops have 50 indexing marks and will allow for .0005 adjustments. The gunsmith can preset the Micrometer Adjustable Reamer Stop to about .020 out and ream without worry. Then re-measure adjust once and make the final cut right on the money. These tools will be available in a couple of weeks from Dave Kiff at PT&G, Nat Lambeth at ngl_services@juno.com and several Gunsmith tool suppliers. See attached photo.
