If you have purchased Martin replacement bridge pins for your import guitar, you may have been disapointed with the fit. Many imports have 3 degree bridge pins, while the Martin pins are 5 degrees, so they do not seat deep enough.
It's an easy fix. You can take it to the shop and get them to do it, or you can do it yourself. I started checking around for reamers and was shocked at some of the prices I found online (Stew-Mac @ $57.49 was the highest). I even checked on Ebay and found some, but with shipping costs figured in they still seemed high.
I finally found one at Harbor freight for $3.49. (

If I was operating a guitar repair shop and working on high end guitars, or making custom guitars, etc., I might consider the high dollar tools. But, for the task at hand...simply enlargening existing holes, the Harbor Freight tool does the job.
I corrected the problem on two guitars in about 30 minutes, which included loosening & re-tightening/tuning strings.
p.s. You might want to add some tape on either side of the T-handle to keep it from accidently falling out on your guitar top.
