Kinya,

When replacing reeds, what size drill bit should I use to widen the opening in the reed and what size for predrilling the reedplate prior to using the tap bit?

I couldn't tell from your articles.

Hello Bluzmann,

Use a #55 Tap Drill Bit for the reed plate and a #52 Clearance Drill Bit for the reed. This will accommodate the 0-80 bolts perfectly.
