| When spinning pegs in for initial fit, use
soap on the shaft and look carefully for irregular wear pattern (from
one pegbox wall to the next). Use 320 grit sandpaper to correct
for irregular wear - that is, if one wall is tighter, sand that area on
the peg shaft so that each pegbox wall bears the same amount of
tension. |
|
| Finished distances from the peg collar to
the pegbox wall are as follows:
D - 11.5
mm
A - 12.0 mm
G - 10.5
mm
E - 11.0 mm
When approaching these distances be extremely
careful: make small cuts with the reamer and check frequently to
insure that you are not removing too much material from the pegbox.
The reamer can be spun counter-clockwise in the hole so that rather than
cutting away wood it is compressing the wood fibers and thereby
enlarging the hole very slightly
For initial fit, leave the peg collars at least 1 mm
further out than the distances shown above and fine tune the fit as they
are "spun-in". At this point (with the collars 1 mm
further out than the finished distances) the peg shaft can be marked and
cut off. Scribe a mark around the shaft on the outside of the
pegbox wall, and cut off the waste with a fine-toothed saw just beyond
the scribe mark. Use a fine file to slightly dome the end of the
peg, rounding it over just to the scribe line. Sand\buff with
successively finer grades of sandpaper up to 1200 grit. |
|
| When done this way, the finished level of
the peg will be slightly lower than the pegbox wall. Liberal
application of peg dope and a lot of "spinning-in" will
generally bring the pegs in that last 1 mm. |
|
| Lightly buff the shaft from the collar to
the pegbox wall first with 320-400 grit abrasive, then with 1200 grit
polysand. With the pegs spun in to the box, and the excess peg
dope brushed away, paint a small amount of mineral oil on the shaft from
the collar to the pegbox wall. Loop a strip of soft cotton cloth
around the shaft at this point and vigorously buff the oil into the
shaft. |
|
| Locate the position of the hole in the peg
slightly distal to the collar from midline on the G, D, and A pegs, and
slightly proximal to the collar (from midline) on the E peg. Mark
the locations with a scribe. Drill the holes with a ___ bit.
Be sure to adequately support the shaft on the off side to prevent
splitting when the drill breaks through. Pass a round needle file
over the hole on each side (radially) to chamfer the edges of the hole
and thus lessen the likelihood of breaking the string. |
