Edge Jointing - JoinTech Clincher Fence Machine Complete Instructions And Setup

EDGE JOINTING

Edge jointing is the process of creating a straight, true and square edge on a board in
order that two or more boards can be joined together. A jointed edge will not make
the sides of a board parallel. To do that, joint one edge of the board then using that
edge as a reference (against the saw fence) rip saw the board to get a parallel edge.
After sawing, joint the sawn edge taking a slight cut (
Using the SmartFence, pieces as small as 6" long x
small as a 1 / diameter straight cutting bit. This can be done safely because you can

use a small cutter and a very narrow gap in the fence. However, you can use a cutter
as large as 1" in diameter and 2" cutting length. For most work on 3/4" boards use a
1 / x 1" long cutter. 1 / shank is a must to keep chatter to a minimum. A
2" 2"
ter, long-fluted upcut spiral is suggested for general use. Use a guard to cover the
exposed bit and the fence gap above the board. Always cut from right to left with the
cutter rotating into the wood. Whenever possible cut with the grain of the wood. If
that is not possible, slow the router speed down and take shallow cuts. Rate of feed
is important. If you feed too fast you get a wavy surface and if you feed too slow you
will burn the wood. Keep pressure down and keep the piece against the fence, first
the infeed side then transfer the pressure to the outfeed side as the piece passes the
cutter. Use of featherboards will help regulate this pressure against fence and make
this operation safer by keeping fingers further away from cutter.

3. Loosen both clamping knobs (3-4 turns) on outfeed section and push knobs
into back of fence (see illustration). This will disengage indexer rods from
keyways on fence body and allow them to be rotated.
4. Turn both indexer rods to adjust to the desired offset. Each number from 1 to
7 viewed through the windows represents fence offsets in 1/64ths inch. For
example, 4 is an offset of
fence body and re-tighten clamping knobs. Do not over tighten.
Note: Both indexers must be set to the same number to maintain
squareness of fence face.
5. Refer to illustration. Rotate the router bit so that its cutting edges are oriented
east and west relative to fence. Place a square or straight edge against the
outfeed side of fence to overlap the cutting edge of bit.
6. Adjust position of SmartFence by using the micro-adjust thumbwheel on
CLINCHER to align cutting edge of bit to the offset (Outfeed) side of fence.
7. Using scrap pieces for test, joint an edge for final determination of your fence
setting and readjust as necessary;
* If your leading (jointed) edge of board catches the corner edge of
outfeed section, your bit is not out far enough. Micro-adjust fence back.
* If your board is slightly concave over its length, the cutter is too far out
and not aligned to outfeed section.
* If your board is slightly convex over its length, it may mean that too
much pressure was applied against fence when passing into and/or
away from the cutter.

For general use in jointing operations, set up the SmartFence as follows; Set the
outfeed section indexer rods to 7 and the infeed side to 6 and align fence to cutter as
above. The infeed section then can be adjusted inward as needed to remove more
material in one pass without any need of recalibrating fence setting.
