Needles
Leatherwork Sewing Machines require 135x17 needles sizes #10 to #22 or
135x16 (DI) leather needles, all available at Sailrite®. A size #20 needle is
used for most medium to heavy sewing.
Needle Types
Round Point
Round Point needles are
used for canvas and soft
leather. Serv7 needles are
modified Round Point needles
that have a humped scarf to
prevent skipped stitches and
reduce needle breakage.
Ball Point needles are
specifically designed for use
with knit or stretchy materials.
DI needles are ideal
for working with dry, heavy or
hard leather.
SD1 needles are optimized
for sewing heavy, dense
assemblies.
Needle Installation
Leatherwork needles are round on top, unlike home sewing machine needles. As a result, proper
installation must be exercised carefully. Improperly installed needles are the main reason users
call for help.
The needles have two distinct sides. One side has
a long channel or groove running the length of the
needle, and the other side has a short scarf (A)
(i.e., a carved-out area) just above the needle eye.
7 |
When installed, the scarf (A) should face toward
the right as you face the front of the machine.
Ensure the needle is pushed all the way up into
the needle bar (B) before tightening screw (C).
