Installation Tips
Peghole spacing: Plate-mounted tuners can't work efficiently if the pegholes are improperly drilled. Our Mandolin Peghead Drill Jig ensures precise 29/32" spacing for accurate alignment for these tuning machines.
Bushings: We recommend the Standard Peghole Reamer to cut smooth, perfectly round holes.
Mounting screws: Pilot holes required. Installing delicate screws into hard wood requires great care and accuracy. We highly recommend the #1712 Depth-stop Drill Bit (5/64" bit) for the pilot hole before installing these screws. Lubricate the screw threads with cutting lubricant (also wax or a bar of soap) to reduce friction and help them thread properly.
