Dual Rim Rod Set for Banjo
This rim rod design is for use with a 3/4"-thick wood rim and a Gibson-style resonator flange.
The location of the upper neck attachment bolt is determined by the neck attachment hole in the tone ring (Gibson-style flathead or archtop tone rings). To install a neck purchased from us, align the bottom of the fingerboard (the fingerboard/neck glue joint) with the top of the tone ring.
Transfer the neck attachment bolt locations to the neck heel, by marking them through the holes in the wood rim. Drill two 5/32"-diameter holes in the neck heel and install the neck attachment bolts.
Drill 11/32"-diameter holes in the wood rim for the rim rods. The rods should be parallel to each other and to the bottom of the rim. The upper hole should not be drilled completely through the rim. The lower hole should be located to allow sufficient clearance for the tailpiece bracket beneath the resonator flange.
Minor adjustment of string height above the fingerboard:
• To raise the string height, loosen hex nut (B), tighten hex nut (A), and retighten hex nut (B).
• To lower the string height, loosen hex nut (A), tighten hex nut (B), and retighten hex nut (A).
• Hex nut (C) should remain snug after any adjustments.
Do not adjust more than 1/16" in either direction, to avoid unnecessary compression or possible delamination of the wood rim. Insert a nail in the small hole midway on the lower rim rod, to prevent the rod from turning while making adjustments.
