Looking for some advise for machineing flashlights

[Tekno_Cowboy]

I'm looking at building a few flashlights of my own, and I was just wondering a few things:

1. Best method for cutting inside/outside threads

2. If anyone here does type II or III anodizing

3. What is easier to start with when working on a first build : Stainless Steel or Aluminum

4. Are there any cheap CNC shops in the US, just in case I can't manage it myself

???

Any help is welcome!

I know the anwers to most of those!

1) There's several good threads in the old archive on cutting threads on the lathe. If you single thread them on the lathe you will find you can match almost any thread. Using taps with the lathe works well too if it's a small, common size.

2) Most folks find a local metal finishing company. HA involves hazardous materials.

3) Aluminum is MUCH, MUCH easier.

4) There are cheap shops, but they are all expensive for single unit jobs. The setup (design and special setups) is the expensive part.

1. I don't suppose you could link me to a couple of those guides? I'll do some searching too, but it usually takes about 3 hours to find what I'm looking for with the forum search tools.

2. I should know that Sulfuric acid is dangerous, since most of the holes in my clothes were eaten away by Sulfuric acid :naughty:

3. Cool, I have tons (literally) of aluminum extrusion, barstock, and rod sitting around after a failed business venture of my Dad's :thumbsup:

4. So once I get a good prototype built, I might be better off hiring a CNC shop to run the production runs?

That's a great place to start. There's a lot of info in the thread "Silly newbie tricks" http://www.candlepowerforums.com/vb/showthread.php?t=54273.

The thread is devoted to hints and tricks and tips for the beginning machinist. Some really skilled people have contributed to the thread.

Here's tip #1. Almost every trick that works for a professional can be adapted to small, benchtop lathes.
