Operating Instructions
Setting up and operating your sled
Introduction
The UJK Technology professional coping sled has been designed toease the cutting of difficult end grain timber sections on the
router table, from short lengths that are tricky to hold through to longer lengths that become a problem to balance and support.
The unique design of the UJK sled solves these problems allowing the safe cutting of end grain sections. The sled is ideal for the
cutting of components that have tenons and scribe interlocking joints. It makes them easier and more accurate to produce, but
also provides support and control making this task safer for the user.
Ensure that the router is disconnected from the power supply
until total set up. Check that everything is assembled and
tighten before using:
1. Load the router cutter to be used into the router, ensure
that the power is disconnected, position the assembled sled
into the T track on the router table. The guide washer will
need to locate into the T track, the washer needs to be
positioned at the front of the base board. Check the position
of the main base ensuring that this clears the diameter cutter.
It is possible to adjust the position of the base board by
undoing the two screws that hold the T bar in place, and
reposition parallel using the 5 pre drilled countersunk fixing
holes on either end of the base board. The aim is to get the
base board as near to the cutter to add support to the
workpiece, but ensure that the board does not make contact
with the cutter by revolving the cutter by hand. Ensure the
screws are re tightened.
2. Remove the sled from the table. Set up the main fence
on the router table; this needs to be set to the depth of cut
required (this might need more than one pass). It is important
that the fence is parallel to the T slot in the table. If using a
cutter with a bearing, set up the fence in line with the bearing,
and ensure that the fence is parallel to the T slot. Reposition
the sled on the table and check the position of the clear
Plexiglas guard. This may also need to be adjusted by
repositioning on the set of pre drilled holes; ensure that it
clears the fence.
3. To load and hold a workpiece, ensure the length stop is not
obstructing by pivoting out the way. Wind up the hold down
clamp heads so that the workpiece can be slid through the
body of the sled lining up parallel to with the nylon fence. The
fence on the router table acts as a length stop. The end grain
face of the workpiece should hit the router fence squarely, with
no gaps. This visual check allows the user to check the set up.
If there is a gap, check that the router table fence is parallel to
the T slot or the grain face of workpiece is cut square.
4. To hold the workpiece within the sled, slacken off the
pressure of the two knobs securing the top clamping plate.
Slide the top plate back to make contact with the workpiece.
The timber section is in positioned and secured between
the top plate and the nylon fence. Tighten the two top plate
clamping knobs to hold the clamping plate in place.
5. With the hold down clamps not screwed down on the
timber, it is possible to adjust the position of the clamping
beam. The aim is to adjust the position of the clamping beam
so that the pressure is central to the workpiece. This is done by
slackening off the two clamping beam locking knobs and the
operating handle on the opposite side of the sled, this allows
the clamping beam to slide along the length of the sled. Once
centralised on the workpiece, re tighten the handle and knobs.
When the clamping beam is positioned, the workpiece can be
held in place by gently tightening down the clamp head onto
the workpiece, securing this in place within the sled. This will
not require a lot of pressure as this will only distort the base
board.
6. The nylon fence can be used to help reduce the splintering
and break out on the back edge of the workpiece. To do this
slacken off the pressure on the workpiece; on the underside
of the base board are the 5 screws that hold the nylon fence
in place. Slacken off all of these just enough to allow the fence
to slide, reposition on the table pushing the nylon fence in
towards the router table fence. Once set, re tighten the screws
to hold in place. The nylon fence can be cut with the cutter, and
will not damage the router cutter; the nylon will get worn away
doing this.It is possible to make a replacement wooden fence
using a key hole cutter.
7. To set up the cutting height of the router cutter, ensure
that the workpiece is held in position within the sled and
positioned on the in feed side of the router cutter. To view
what is going to be cut away with the router cutter, look in
from the far end of the out feed fence of the router table, raise
or lower the cutter height using the height adjustment of the
router. Ensure power to the router is still off.
