NEW! 16mm / 5/8" Replacement Pins
Endpin assemblies whose pins don't have a threaded point.
Available in either carbon steel tube with 1mm wall or solid
hickory. Other materials available upon request.
Revolutionary Endpins and Sockets
One thing which I think all bassists and luthiers agree upon is
that there are a whole lot of poor endpin sockets in the world.
The pin can slip. The thumb screw can strip. The fit into the
bottom block can be poor.
The biggest innovation of the RobPin is the "Bottom Block Rest" which
takes on most of the bass's weight. This eliminates most of the
typical stresses on the socket, bottom block, and pin.

Once you have it adjusted to your preference, you only slip it in and
out of the socket when you are packing and unpacking the bass. When
detached, it might even fit into the accessory pocket of your bag! The
set screw in your socket needn't even be especially tight. The weight
of the bass goes onto the "Bottom Block Rest", keeping the bracket
Height and angle adjustment:
The RobPin comes with three interchangeable rods of different lengths,
giving it a good range of height adjustment. The angle of the pin
going to the floor can be set at 25°, 35°, or 45°. If your
endpin is not 10mm, then adapters are available. If it doesn't come
out of the socket, then you naturally need to remove the holding pin,
or have your luthier do it.
More about the RobPin
Anodized aluminum. Made in Germany. 1/4" UNC thread.
Also, you can have the unthreaded shaft either the standard 1/4"
diameter, or 5.1mm. The smaller shaft means that you don't need to
re-drill after making the pilot hole. This simplifies installation,
and likely improves accuracy.
Also, many people make the pilot hole with a 3/16" (.1875") drill. I
strongly discourage this practice. A #7 drill (.201", very close to
5.1mm) or a 13/64" (.203") is standard machining practice. Since maple
swells with humidity I recommend a 5.2mm (.205") pilot hole, and have
drill bits available.
This clamp is an improvement over an existing idea. A luthier friend
has been bugging me for years to develop this, but it was not until I
used one that I understood how useful they are. The back plate turns
9° left or right, but holds a right angle in the vertical axis.
Made of extremely hard Bamboo plywood with stainless screw and rods,
and the 1.5mm silicone pads are non-stick and easy to keep clean. 26cm
maximum opening. The advantage over spool clamps is that they don't
twist when tightening, conform to the tapers, and cover a wider area,
so you get a seam closed way faster than before!
Tailpiece Wire / Clamp
This cable/clamp system has been designed to maximize flexibility and
strength while minimizing bulk and weight. The cable is 133 strand
1/16" (1.6mm) super-flexible stainless aircraft cable with a nylon
coating. Break strength is 480lb. (218kg). Typical installed weight is
10 grams. The aluminum collar is 3/8" (9.5mm) diameter. A 1/2"
(12.5mm) collar is also available for cables up to 3/32" (2.5mm).
