HOW TO USE
Step 1. Mark the center line
Mark the center marking line for the dowel holes to be drilled on the two boards to be connected.
Step 2. Match up the lines
Align the center marking line on the board with the white index mark of the jig. Tighten the jig firmly, but do not over tighten.
NOTE:
If the board is placed at the edge of the end jig, add a piece of scrap wood
of the same thickness to the other end to avoid uneven stress, causing bending
jig.
Step 3. Drill dowel hole
Put the drill bushing into the guide hole of the correct size, and insert the drill bit that meets the size to drill the required depth. Repeat the same process on the other board.
Step 4. Edge-to edge joints
Apply glue to dowels and hole. Insert the dowels in one board, then put in another board , and clamp securely until dry.
CENTER CALIBRATION
Measuring the Gap
Step 1.
Tightly clamp a piece of dimensioned/squared wood that is wider than the
center block.
Step 2.
Switch your caliper into the metric system and measure the gap between the
centerpiece and the orange plates. The measuring spots should be the center
point of the fences, which is right above the lead screw. Record the measuring
results of both sides and calculate the delta.
If the deviation of both sides is under 0.2mm(around 1/128″), the calibration
is complete.
NOTE: if your caliper does not work in the metric system, manually convert the readings into metric results.
Adjusting the Gap
Step 1.
Loosen the lead screw to release the wood and ensure the gap of each side is
wider than 1/4″ for later adjustment.
Step 2.
Remove both PH screws on the locking plate of the adjusting end.
Step 3.
Pull the locking plate towards the centerpiece for clearance to adjust the
adjuster nut.
Step 4.
The pitch of the lead screw is Imm per revolution. If the gap of the adjusting
end is wider than the fixed end, turn the adjuster nut clockwise, and vice
versa.
Step 5.
When the gap deviation is 2mm, turn the adjuster nut by two rounds. If the
difference is 0.8mm, turn the adjuster nut slightly over 3/4 round.
Step 6.
Push the loose locking plate towards the adjuster nut then fix both parts
together with the PH screws.
Fine adjustment
Step 1.
Repeat the steps under
“Measuring the Gap” to verify the distance deviation. If the deviation of both
sides is under 0.2mm(around 1/128″), the calibration is complete.
Step 2.
Repeat the steps under the section of”Adjusting the Gap”.
Step 3.
You can repeat this process cycle until achieving a satisfactory setup.
