Laser Cut Hardwood Knob with a Threaded Insert
Instruction
Information
This handy wooden knob with a 1/4"-20 threaded insert has a variety of uses in a workshop. This workshop knob can be used for woodworking jigs, table saw fixtures or clamping parts together. The diameter of the knob measures a comfortable 2-1/4" outside diameter & includes risers at the bottom for greater ease of use in tight situations. Included are the parts to make a counterbore jig with a drill press. The counterbore will ensure the threaded insert sits flush with the top of the knob.
Instruction
Step1: Hardware Used
Qty 1 - Tee Nut, ¼"-20, Fastenal #1137964 or equivalent
Qty 2 - 5/16" Flat Washers
Qty 1 - 5/16"-18 Hex Nut
Qty 1 - 5/16"-18 Hex Bolt
Notes: The Tee Nut will be permanently installed into the Knob. The bolt, washers & nut are used for gluing the knob parts together.
Step2: Laser Cut 4.5mm Thick Plywood Parts
Step3: Glue Up Knob Parts using hardware (except Tee Nut)
Using a good quality wood glue, apply glue between each wood surface & stack the assembled parts as shown. Tighten the nut securely. Wipe out any excess glued that has squeezed out. Allow to dry for 2-4 hours. Remove the nut, bolt & washers leaving only the glued up knob.
Step4: Glue Up Counterbore Drilling Jig
Using CA glue (or wood glue or a combination of both), assembled the parts of the drill counterbore jig as shown.
Step5: Add a 3/4" Dia Counterbore to top of glued knob
Using a drill press & a ¾" diameter Forstner drill bit, clamp & align the jig to a drill press table. Insert the glued knob into the jig. Drill a ¾" diameter counterbore into the top of the knob at a depth of 1/16". Remove the knob from the jig. Repeat if you are making multiple knobs.
Step6: Add threaded insert (Tee Nut) into knob at counterbore
Place a ¼"-20 Threaded Insert (a.k.a. Tee Nut) into the end with the counterbore. Hammer the threaded insert until it is flush with the top of the knob. Add 3 coats of clear acrylic finish. Presto! You're done!
