How long does tritium stay bright?

10- 12 years ish. I forget the exact half life. It will lose its brightness over time. I was able to get phaux some replacement pieces for a acog that had tritium as an illumination source that had gone dim.Comment

You interested???
I found a power supply on ebay that its output is rated at 0-120vdc and 0-3a for about $300 shipped. I have found others that are the same voltage and 1a of output for a little over $100. One thing I am not sure of is exactly how much current I really need. From what I have read doing small stuff is not going to require much. The larger items will require more though. I would like to buy as much power as I can right up front. Does that seem worth it?Comment

There are any # of easily accessible products to make that. What seems to be more important is a good etcher.Comment

Interesting. I ask because it might be possible to approximate tank resistance. If you know that it might help determine how much power you'll need.Originally posted by inline 6 View PostMen have become the tools of their tools.

I didn't anwser directly because I have not actually done any yet and have not made up any of it. I am doing small pieces, keep that in mind. I called a place that has 30yrs. experience with it and they sell a small power supply that only goes up to 1a of current. The told me that was plenty for small parts. They sell a larger one that will do 7a of current and they said that one will do several square feet of material at once. So I man going to try and find something in the 1-3a range tops.Originally posted by BERNIE MOSFET View PostComment

Would it be easier to get the desired ranges out of 220v rather than 110v? I am finding some cheaper units out there that will do what I want but they are setup for 220vac input only.Comment

Use some deep cycle batteries in a bank and recharge them occasionally.
or 220v like aboveComment

Several ways I can think of.
This could be done first with a full bridge rectifier circuit that will take the AC 120Vrms and rectify it to a about 108Vdc. A buck boost converter can raise(boost) or lower(buck) that 108Vdc to the level that you would need.
Any easier way with less regulation of the output would be to use a variable AC to AC transformer with a full bridge circuit. The output Vdc would vary as the transformer changes.

Why not use a heat treating oven or jewelers kiln to heat color the parts?Comment
