in step #1. A four-way prop wrench works well for
this operation. Twist the bolt all the way into the roller
until the head contacts the wood, or strong
resistance is felt, then remove it.
3. Rub some bar soap or paraffin wax as a lubricant
onto the shaft threads of the 1/4-20 roller knob, then
screw the knob in and out of the threaded hole to
distribute the lubricant. Do not use excessive force
when performing this operation to avoid breaking the
knob or stripping the threads. If the threads tighten
up, remove the screw and add more lubricant. You
want this screw to be very easy to install and
remove.
FINAL ASSEMBLY
NOTE: The following steps describe assembling the
Smart Stripe for right-hand operation. If you are
left-handed, simply switch the position of the knobs,
hex nut and dead pin from one side to the other.
1. Now is an excellent time to decide where you
would like to mount your Smart Stripe. It need not be
mounted permanently, but it will help to have it
mounted when loading the roller. Position the base
where you will mount it, then use a pencil to mark
the mounting screw locations on your workbench.
2. Remove the backing from the pressure sensitive
decal and apply it to the recessed area in the base
as shown on the box cover.
3. Attach the right and left uprights to the base with
four #6 x 1/2" sheet metal screws. Notice that the
right side is fixed and the left side is adjustable.
Tighten the left side screws just enough to hold the
upright in position, but still allow it to be moved.
4. Use the roller as a spacer to set the distance
between the front and rear uprights, then tighten the
screws on the adjustable side. Make sure the
uprights are parallel to one another.
5. File or grind a 3/16" wide flat spot 1/16" from
one end of the threaded steel shaft.
NOTE: The blade holder should be “broken in” by
screwing the threaded shaft through it several times.
Turning the threaded shaft with an electric drill works
well for this job.
6. Insert the threaded shaft into the hole nearest you
in the left hand upright. Verify that the threaded
insert is centered, with its tabs overlapping the sides
of the right and left blade holder, then thread the
shaft through the blade holder assembly. Keep
turning until 1-1/2" of thread protrudes out the
opposite side of the blade holder. Insert the threaded
shaft through the hole in the other upright.
7. Install the small knob on the threaded shaft on
the flat spot end. Install the 8-32 x 1/8" Set Screw
into the small Knob and tighten.
8. Wrap a thick cushion of paper towels around the
threaded shaft to protect the threads, then grip it
tightly with pliers. Use a 7/16" prop wrench to thread
the nylon hex nut on the end of the shaft as shown.
NOTE: This special hex nut is intentionally not
threaded. When fully seated, it will remain locked in
position. Thread the hex nut onto the shaft until it just
touches the upright, to remove any side-play.
9. Hold the roller between the uprights with the
threaded hole on the right. Slide the 1/4" dead pin
through the left upright into the unthreaded hole in
the roller. Insert the roller knob through the right
upright, then screw it into the roller until you feel a
little resistance.
10. Check your work. Does the roller turn freely
without side-play? Does the threaded rod work
smoothly, also without side-play?
