Any laser guru's out there

RPE1

I admit I know nothing about lasers. So I need some help. I want to use a laser for tool positioning. I ordered a 650nm, 5 mW, Red laser module with adjustable focus. 4.5-5volt. I also ordered battery case to hold 3-AA batteries, giving me 4.5volts.

All I want to do is project a red dot on a paper plan to guide a tool. The laser will have to be on for a while.

Will my plan work?

Do I need more hardware?

I know many have used lasers to position tools for hollowing rigs. And that is essentially what I am doing.

Any help would be appreciated.

Should work fine. I use a similar set up for hollowing. Often my laser is on for 60 minutes at a time. Battery life is many hours.

Not an expert but did stay at a Ramada Inn once.

I use a laser centering device in my milling machine. It has small button cell batteries and has worked for hours so far. Based on experience with playing with cats and laser pointers with similar button cells, a red laser with 3-AA batteries might be able to run continuously for days.

BTW, the centering laser I use has a nice feature - it uses a rotating polarizing filter to make an extremely small dot, fairly dim. A large, bright dot is too hard to see the position precisely.

That will work just fine. The holding method is important. It should be easy, accurate, and fast to set.
