I know what DOESN'T work is the specialty kits they market to rejuvenate headlight lenses.

Yep!
Mostly they are fine sand paper all the way to 1000 grit.
Auto body rubbing compound will do that job just fine at a fraction of the $$'s.
Heck even tooth paste (very mild compound) will do it also with more elbow grease.

Good idea.... I will order today!

I just made it a habit to pull the cable every time I'm in the garage. No more standing on my head to bleed off the moisture (Cable operated tank drain).

Yup!
3M auto body compound works great!

Most probably know this already but if you are needing to find the center of round stock to drill a hole, the quickest way I have found is to use a ruler or something straight on top of the round stock, then place the drill bit on top of the ruler. As the material is moved back and forth, the ruler will rock from side to side accordingly. Once the ruler is straight you are in the center of the material, or at least close enough for most purposes. The same can be done on a lathe to get the cutting bit in center.

I have a tool for that. Chuck up the round part and the V will pivot on the round stock until the two lines are lined up. Won't work in the lathe, but works on mills and drill presses.

got a link?

This was handed down to me. I'm sure it was purchased prior to the internet's existence.



Thanks BB.


Yup, I have seen those before. I'm just cheap though, I use what is handy.

I used it for work when I was a toolmaker, so I had to be precise. If I needed to be more precise I'd use an edgefinder on both sides and split the difference. That only works with a mill, though. If I needed it to be within 0.0005" I'd use my indicator, but that's a whole different ballgame than garage work.
