I ordered a laser kit this afternoon ; a Survival Laser 660nm 300mw. Already shipped, due to arrive this friday/1 july! (THANKS, Gary!!)
I've been advised that I might need teflon tape for the focusing system.
I am disabled with a heart condition, and I do not drive due to my cardiac medications. I can walk short / moderate distances (say, about 45 minutes) (but NOT in this 100+ degree heat we are having!)
SO... I more or less "live online" - something I have had to learn to do since my last round of heart surgeries (2005). I can't "run out to the local hardware store".
I order a lot of stuff from Walmart. It's cheap and usually convenient.
When searching the Walmart site for "Teflon Tape" we have this:
Walmart.com: Search Results for "teflon tape"
... 25 results; 24 different tapes, and a liquid thread sealant at the bottom of the page. (for some reason the liquid thread sealent is "non-drying", whatever that means).
Dumb newbie question: Will "any" of these do? Is there any PARTICULAR reason to choose one of them?
EDIT: About thickness... the first batch towards the top are "standard density", with no thickness listed. Then comes a batch that are all "3 mil". There are a couple that are "3.5 mil". And I think some do not really list density or thickness.
-----
And how about that liquid sealant?

Unfortunately, express shipping for this is unavailable. If I ordered it today, the arrival estimate is between 8 july and 18 july (?? sheesh).
-----
Are there any alternatives to Teflon Tape? I did a few searches...
One person said they put a tiny amount of superglue on the threads. BUT that stuff crystalizes (?). Even a TINY amount of "superglue crystal dust" getting into the lens or the diode...
(and I don't have any superglue at present)
In a couple of searches, a couple of people (including jayrob, I think) mentioned that there are alternatives to teflon tape, but did not say what they were.
The other day, while reading old threads (for general laser knowledge), it SEEMS like I accidently ran across this issue - not really understanding it at time. Someone mentioned smearing "something" on the threads, as an alternative to teflon tape. I can't remember what it was, and I can't seem to find the thread.
-----
I'm aware of the cautions when using teflon tape... that it can fray, and pieces can get to the lens / diode. I see that as meaning use as LITTLE tape as necessary, screw the lens in and out a few times after applying the tape, and immediately remove any pieces that have frayed off. AND check it now and then.
Thanks
