Making wooden screw down knobs.

materials=Coach,Bolts,Plywood,Glue,Epoxy resin,28 mm/35 mm forstner bit or spade bits,60 and 28 mm Hole saw 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 Hole saw and forstner bits.

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 mm

Cut out the knob body with the 60 mm Hole saw ,then cut out the spacer with the 28 mm Hole


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!https


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!https


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.

Everyone woodworker can always use more knobs. Making your own sure does save some dough. Nice work on those knobs and video!
Thanks for sharing.
