Introduction: Making Wooden Screw-Down Knobs ( the Easy Way )
Making wooden screw down knobs.
28 mm/35 mm Forstener bit or spade bits
60 mm Holesaw
Step 1: Marking Out Template
I've made a simple template for the shape of the wooden knob, draw 2 circles 1 at 60mm and the other at 75mm divide the 75mm in 3 equal parts and transfer the centre and the 3 out side marks through to the plywood with a point . then drill through with 3mm drill then countersink the holes on both sides. (the countersink help with locating Holesaw and Forstner bits
Step 2: Cutting the Handgrips
Using the 28 mm forstner in the middle hole drill down to 6 mm this is to locate the spacer when assembling, now drill right through with the 35 mmbit all the outer holes
Step 3: Hole Sawing
Cut out the knob body with the 60 mm Hole saw ,then cut out the spacer with the 28 mm Hole saw
Step 4: Putting Rounds on and Inserting the Coach Bolt
Round the main body of the knob I'm using my table router for this but it could be done with a rasp.
Insert the coach bolt in main body of knob,the coach bolt as a square just under the head this needs to be hammered flush into the plywood
Step 5: Final Assembly
Glue the 28 mm spacer with wood glue and epoxy the washer to the bottom and then tighten everything down with a nut and wrench
Step 6: Finish and Paint
Put some nuts on the coach bolt to protect the threads from the chuck and then sand to a smooth finish i used automotive paint primer and top coat.
