MALE/FEMALE THREADED KNOBS

[morsa]

On the net there are several models of homemade knobs; construction techniques are essentially the same in all of them. Here I show some I did, taking ideas from here and there.
They are made with leftover MDF 1/2"; measure 2" in diameter and have six points:

Cutting valleys with 5/8" Forstner bit.


Cutting the knobs with crown bit 2"; on paper you can see a pattern with radius every 60 degrees.


Rounding out the ridges at the lathe. It could also be done at the drill press.


Rounding out the valleys with Dremel mounted in router-table accessory.


Elements ready for assembly. The small discs were cut with crown bit 1" in diameter.


For female knobs, the "T" nut is embedded in the small disk on the side to be glued to the star-shaped disk; for male knobs, "T" nut will overlaid on the free side of the small disk, the screw is tightened before gluing the elements, and the screw head fits in a recess created in the star-shaped disc. I used two components epoxy glue.

Finishing; with application of sealant,


and black enamel.


This is the final result.


Regards.
