Anybody build Dan Gelbart angled laser centre finder?
PekkaNF:
Little progerss today, I got a tad over 1 hour of garagetime and that was time well spent.
I made a POC (E.G. quick and dirty) test.
I desided to use plastic cable gland to insulate laser from metal, I read somewhere that some lasermodules have one polarity on body. Also rubber grommet holds the laser pretty well.
Body was made from sheet metal, I tested 20 degree and 10 degree angle. Easy to change angle and fast to make.
I used plastic batteryholder, lashed with wire.
5mW laser was way too bright with ambient light. Glare/diffration was disturbing.
I would prefer very much smaller and dimmer point. Has anybody tried 1mW and/or green laser?
Right now it looks very usefull on round/slatend surface and round hole/boss, but not that usefull on flat surface and scribed mark. Pretty sure weaker beam would help. I don'ät know ti what degree.
What do you think?

The results look just like that of the video Pekka :thumbup:

I just made a test rig. mechanically it's still all wrong, my only goal was to test 5mW red laser. Very tempted to order lower power module, but it would be nice to find unit with smaller beam diameter.

Make the holder solid instead of sheet metal? Machine vibration may transmit to the sheet, and that might be causing a thcker line than you'd get with a more solid mount.
Arbalist:
looks pretty good to me, just need to reduce the brightness.
