4mm Knob Making Mandrel


4mm knob making mandrel



This 4 mm mandrel is made from high grade 316L Stainless Steel. It has a screw thread on one end.  Screw our M4 sleeves onto this end of the mandrel and simply wind the glass on the sleeve to make your own knobs .

We suggest putting a little dot of bead release to seal the end just to prevent any glass entering the thread.

M4 Sleeves for these mandrels can be found here

I also have a Knob making kit with a tutorial
