RE and Blord, have you gotten your springs from me? And if so, did you have any luck testing them?
Sorry to bump this after a few years, but I wonder if anyone has ever found a good source for external springs. SL has them, but $5 a piece is just way too much...
There was also this thread: http://laserpointerforums.com/f49/external-lens-spring-76107.html
Another possibility is if someone could get the exact measurements of the SL springs, diameter, length, and lengh when compressed, then you could probably order some cheap from someplace that makes springs, but there would probably be some large minimum order.
I use a spring and tape but not the Chinese tape. The mm spec is too thin more of a chance of getting a piece onto the window of the diode. i use a hercules teflon tape . I'm a pipe fitter and this is thick tape. one time around the threads and your good to go forever.When you use the tape keep running your fingers around the threads it will seat it deep into the threads. the more this is done the better it will form. This will help a lot try iy you'll like it really.
The first third of the barrel closest to the diode doesn't need tape. start a little higher to the focal point.
