I have been using an Akeda dovetail jig and just ruined the guide bushing.
It is marked 0.438", which is the exterior diameter. I can pay $25 ( 1/2 is
shipping) or use an old Porter Cable bushing which varies about .002 to .003
in diameter as you go around it with a micrometer.

I find it hard to believe that that .002" variation would be a problem.
Anybody had this experience and how did you resolve it.

Thanks

About 0.004 is all it takes to show up as a gap in a joint.
