Making A New Pot Lid Knob

Making a new knob for one of my mom-in-law's pot lid

Difficulty Level (Easy, Medium, Hard, Insane):

The very first "actual" project that I used my lathe for shortly after I got it was replacing a little knob for one of our pot lids. Now, over half a year later I guess word got around that these knobs can be "fixed" so my mother in law brought her broken knob along with the lid it came off of.

This one was actually quite simple. The biggest challenge was to keep the Teflon in the chuck because it's so slippery and it wasn't a very big piece.

All I had to do is take a 2-1/8" hole saw, cut out a slug out of one of a couple of 1" thick pieces of Teflon I bought about 6 months ago for $20 at a scrap yard (which I've used for several small projects since), chuck it up in my lathe and turn it to its final shape.

Then I had to bore the inside out (0.160" deep), drill and tap a hole and clean it up and it was done. Scored some extra points with my mother in law (not that I had to though).

$20 bucks maybe?

It works great and my mother in law is happy
