Star patterns in milled parts

I have some old tools that were originally nickel plated. They have become dull and rusty over the years and I would like to refinish them. Do I have to remove the old nickel before plating? Can I plate new nickel over the old nickel (once it is prepped)? Is there a way to polish the old nickel...

I am looking to build an oven that uses a torpedo style heater. I have no knowledge whatsoever of electronics and would trust a monkey with a gun before I trust myself to wire a pid. Would it be possible to run the torpedo heater without a pid and if it is possible would it be smart?

Hey Guys!

So I finally decided to ditch the Anodizing Co. I had been using to anodize the custom pickguards I make for my customers guitars I build. I've done several weeks of research, but by NO means am an expert on anodizing...
