Seems like every time we go to a festival
to show our products, folks come over to our booth and ask "Do you have any
Siminoff shirts?" The answer has
always been "Sorry, no" but now we can say "Yes." We've just added T-shirts and
caps to our catalog. The T-shirts are olive-colored and have an illustration of
the end-view of an F5 mandolin on the front of the shirt, and the back-view of
the mandolin on the back of the shirt so they can see you both coming and
going! The caps are adjustable (but as you can see, a bit too big for my
grandson) and are in brown. There's more info about them in the product
Many of you had a chance to read the story in Mandolin Café about my involvement in the launch of Gibson's F-5L
mandolin back in 1978.
We have also posted a PDF file of the article (although this one has only black
and white photos) in the free downloads section of our web site at
- it is at the very bottom of that page. And, by the way, you will find many
more free download documents there that you may find informative.
There has been a lot of interest in the
H4 mandola, and we have had several requests for H4 mandola kits. The H4
differs from the H5 in that the H4 has an oval soundhole, an 11-fret neck
(i.e., it joins the body at the 11th fret as compared to the 13th
fret for the H5), a 4° neck pitch (the H5 is 6°), and the fretboard rests on
the soundboard instead of having a fretboard extender like the H5. We have been
working for several months to develop the patterns and tooling to build the
parts for this instrument and will be officially announcing our H4 Mandola Kit
next month. At the moment, we have posted our H4 rosette (which is different
from the F4 rosette) and the H4 neck to our on-line store, and we have
completed the H4 ProSeries Drawings, which Kali has added to our on-line store
Lastly, a reminder for those of you who
may have missed last month's newsletter that you can now follow us on Facebook.
Aside from tidbits about the daily goings on at Siminoff Banjo and Mandolin, we
are also posting short videos that focus on various luthierie tasks. Please visit us on Facebook.
Thanks for building with us...
I've always felt that I had the uncanny
ability to read wood. Before we lay open a board or glue up a soundboard or backboard
set, I test my "magic" powers to evaluate the outside of the wood and try to
predict what the grain and figure will look like once the board is carved or
shaped and the grain is laid open. Usually I'm close. But every once in a while
Mother Nature outsmarts me, and we discover natural anomalies that prevent us
from selling the board as an A, AA, or AAA grade. Aside from natural
discolorations and blemishes, I've discovered insect remains in their little
burrowed holes, blind holes in maple that are the remnants of bung holes
drilled into the tree to drain maple sap for syrup and plugged back up by bungs
left to be grown over by subsequent tree growth, parts of barb wire fencing,
nails, bullets, buckshot, and more. Of course, boards with these physical
defects are either discarded, used for test instruments or find their way to
campfires. (I love camping with music friends and watching their expressions as
defective soundboards or necks are thrown into the fire. My wife, Rosemary, and
I, and Lynn and Amy Dudenbostel had the pleasure of giggling about that while
feeding a campfire in the Great Smoky Mountains.) The boards with natural
discolorations and blemishes, however, go into our Seconds box to be sold at
festivals or made available to those luthiers who visit our shop looking for
bargains. So, from time to time we end up with some soundboards and backboards
that we can't put in our kits or sell as first-line boards.
We have about two dozen soundboards and
backboards in our Seconds box, and they are available at very good prices (50%
discount). The Seconds are carved to the same graduations as our regular
boards, and aside from their cosmetic blemishes, they are perfectly usable. In
most cases, these blemishes are invisible when the boards are stained and
shaded. There are also a few boards where there was a machining flaw in the
figure on both halves of the board, but all of our Seconds are usable or easily
repairable. If you are interested in seeing our list of Seconds, drop me an
put "SECONDS" in the subject line, and I'll send you a list. And, if you see
something on the list you would like to see a photo of, I'll be glad to email
you one. Please note that because of the price reduction and handling costs,
Seconds are sold as is and are not returnable.
· Luthier's T-Shirts - Our luthier's T-shirts are of made
of high-quality olive-colored cotton and are silk screened on the front and
back. The front of the shirt boasts a front-end-view illustration of the F5
mandolin, and the back of the shirt shows the butt-end (as if the mandolin is
going through the shirt). Shirts come in adult S, M, L, XL, and XXL, are part
#2110 and are $14.95 plus P&H.
· Luthier's Caps - You don't want to be dressed in
one of our shirts and not be wearing a cap! Siminoff luthier's caps are brown
and are beautifully embroidered with a front view of the F5 mandolin. Caps are
adjustable for a wide range of sizes. The caps are part #2100 and are $13.95
· H4 Mandola ProSeries Drawings - The latest addition to our ProSeries
Drawing sets is the H4 Mandola. As a result of its oval soundhole and unique
soundboard, the H4 delivers a full, rich, deep tone. This set features 19 pages
and includes numerous "variations" so that you have the option to build an H4
mandola with more contemporary features such as the 13.5° peghead pitch of the
H5 rather than the 17° peghead pitch of the H4, the full fingerrest of the H5
vs the scant fingerrest of the H4, and more. All variations are clearly
indicated as to the differences and options. The H4 Mandola ProSeries Drawing
set is part #DH4 and is $34.95 plus P&H
|Luthier's Tip: Repairing Ribs|
Rim bending is not a project that stirs
every luthier's spirit. Even for those of us seasoned benders, we occasionaly
get a piece of wood that has a mind of its own and either doesn't want to bend
the way we want it to or cracks when and where we don't want it to. One way to
get closer to good results is to ensure that the grain of the wood (as seen from the end of the wood) lays as flat
as possible as shown in "A." Grain on the bias ("B") is fine as long as it
doesn't approach grain going across the ribs as in "C." Ribs that have grain in
the "C" orientation are very difficult, if not impossible, to bend.
If you end up with light-to-mild cracking
across the ribs, it is better to try to close the gap first rather than just
trying to sand it out. Successful closure can be done with cyanoacrylate glue
(Crazy Glue®), some wood cauls that are prepared to the shape of the curve, wax
paper, and two 3" C-clamps.
Prepare the wood cauls to the right
curvature. Sand both the female and male faces of the cauls smooth. Cut two
pieces of wax paper about 3˝ x 3˝. Test fit the cauls on either side of the rib
and set the C-clamps to the approximate opening (so you don't have to spend a
lot of time turning the clamps after you have applied the glue). Run a bead of
cyanoacrylate glue down the joint, put a piece of wax paper on either side of
the rib (over the glued area, of course), position the cauls, and tighten the
clamps securely. The photograph shows only one clamp, but it is ideal to use
two clamps so that you fully tighten the cauls on top and on bottom (apply a
clamp from either direction so you have full access to each clamp's turning
lever). Allow the glue to dry for 15 minutes. Remove the clamps and cauls, peel
away the wax paper, and sand the glued seam smooth. The joint should be
virtually invisible and will become more invisible as you sand through the
upper few grain layers of the wood.
Usually, these cracks occur in the tight
bends, and it is in these areas that ribs are typically shaded darker than
other areas, so the seam will become even more invisible.
