Vintage banjos from yesteryear feature a friction type non geared 5th string tuning peg with a 1:1 ratio as seen in this original nickel-plated tuner on a Vega Martin VIP-5 banjo manufactured in 1975. Some collectors prefer to leave these original parts in place to sustain the value of a classic instrument.
As seen in this 1994 gold-plated Stelling “Masterflower” 5-stringer, modern banjos come routinely out-fitted with a 5th peg bearing a rounded gear box with fine-tuning ratios.
In his workshop experience of installing modern geared 5th string tuning pegs, the BRC founder has encountered a couple of banjos in which it was discovered that the truss rod within the interior of the neck was oddly positioned and blocked proper seating of a contemporary tuner. When inserting a newer tuning device, the BRC craftsman prefers that the rim of its rounded gear box sits firmly on the outward slope of the neck at the fifth fret. This facilitates the geared tuner to be stable and snugly secured in the peg hole which has been lined with a mix of wood glue and sawdust. Rubber band compression protects its alignment during an overnight drying phase.
On the rare occasion when the truss rod preempts proper seating of the new tuning peg, the BRC founder fashions a wooden collar to act as a spacer and stabilize the replacement tuner. Shaped somewhat like a signet ring, this collar is constructed by stacking thin layers (about 1.8 mm thick) of maple veneer united with wood glue. The buttressed “Show-Me” ring is then gently sculpted with sand paper.
The above vintage 1968-69 Baldwin C banjo originally came from the factory with an old fashioned 1:1 ratio friction 5th tuner, but the truss rod location prevented proper seating of a replacement geared tuning peg. The Show-Me collar was installed to stabilize the new 5th string tuner and is hardly visible to the viewer.
On the underside of the Baldwin C neck, the buttress of the ringed Show-Me collar is barely detectable to the eyes of the musician and does not interfere with musicianship.
The above banjos are part of his antique and active instrument collection, and the BRC founder wishes all our readers to be safe and be well. Peace.
