So even though I'm on vacation, I decided to go to work...WHAT!!!...(well I don't have a lathe at home) to try and make a bolt knob. To my dismay we were all out of 1" aluminum rod but we did have some black nylon. I thought, why not, it's very strong, very resistant to chemicals and very easy to shape. This is what I came up with. I think when vacay is over I'll try out some different designs and probably make one out of aluminum. Nothing better then making something for yourself and getting paid for it!
