Over the years, I always had a variety of instruments to
make at any one time and therefore have never really been in the position to
make batches of any one component. Making three mandolins, all the same shape, has
allowed me to do this recently and it certainly is more efficient. Take these
three necks; they all need to be routed take the carbon fibre reinforcement.
you get the router and jig out, set-up the cutter this takes the same amount of
time whether you are going to route 1, 3 or 50 necks. Even cutting the CF to
length, hack saw out, marking out and cleaning up the dust afterwards- time saved.
To ensure accuracy, I use one of these jigs from StewMac to
drill the holes for the tuners.
The holes are drilled ¼” for the tuners shafts
but then the holes have to be counter-bored to 8.2mm to take the bushes. Having
24 holes to counter-bore, inspired me to make this simple jig. The steel tube
is aligned with the drill, the ¼” hole slips over the tube, toggle clamp to
hold it firmly and drill. The phrase involving old dogs and new tricks springs
And here are the 3 completed heads.
You’d have noticed that all of the heads have wings glued on
to them. The head is the widest part of the neck and it would be such a waste
of valuable resources to have the whole neck blank the same width as the head.
