Huh! I actually have some tape exactly like that. I got it because it was supposed to be wrapped around threads of water pipes before joining them together. Supposed to prevent leaking. When I threaded the pipes together, the tape shredded right off. Is it supposed to do that? Is there...

I'm not home right now, but maybe when I get the chance, I'll take the lens barrel out again and see if there's still a spring in there. I know for sure there never was one between the heatsink and focusing ring. When I removed the lens barrel the first time, I made sure to keep the host...

Is the purpose of that spring simply to keep the heatsink from wobbling around? From what I'm understanding so far, that's the case. But I ended up putting a thin rubber shim between the side of the heatsink and the inside of the host this morning. That seems to be holding it tight now and...

I sure hope that little spring isn't too important because I never saw one. Hopefully, it remained attached to wherever it was and I just didn't notice it.

I guess great minds think alike! :crackup: But I did end up getting everything all back together again and working right. When I was about to give up, I figured I had nothing more to lose, so I unscrewed the top portion of the host, took out the heatsink that was rattling and put a very thin...

Got it done. Thanks! I ended up with about 3.5 hours of sleep. :tired:

No offense taken. But trust me, I took a lot of precautions so it took me quite awhile to do these correctly and safely. Eye protection was used too of course. I would have done something like this with something lower powered, but I don't have anything else. As for burning--I actually feel...

You mean on the threaded part? How about using Lock-tite? Would that have the same affect? The idea is to keep the 2 parts together, right? I had originally inserted a paperclip between the ring and the flat silver surface to keep the focus from turning so easily. The paperclip has gone...

Look at the picture OVNI posted. That's the part. But on mine, the ring portion became separated from the cylinder portion. I have them back together now. I didn't realize turning the ring is supposed to turn the cylinder to focus the laser. Since they separated, there was no longer any...

That's ok, it doesn't appear that the lens is missing after all. I scoured the floor looking for it, but it was never missing. Since the ring came off and then putting it back on resulted in having a "blue flashlight", I had assumed there was a lens behind the ring part. Now I learned that...

Yeah, that's it, except the ring portion came completely off the threaded cylinder part. When I screwed it back in, it wouldn't focus anymore. Then I discovered that they were supposed to stay together and turn together to focus. Since they came apart, the ring part turned by itself. I...

I just received my SF501b 1.5--1.8W laser from Scifi lasers and now the focusing ring came off and when I put it back on, the only light that comes out is similar to a flashlight. I only had it for 6 days and now it's not shining like a laser anymore. FWIW, that focusing ring needs to be...

I'm taking requests for more pics like the ones above!

I just wanted to amend my review with a couple more videos that I thought would be helpful. I had originally stated that the beam on my laser couldn't be seen during the daytime. I should point out that it was sunny that day. Now we've finally had an overcast day with some light rain. I...

The price for the laser being discussed is $129.99. You can go to this site: SF501B 445nm Blue and then select 2W--2.4W as the version. Then you'll see that price. It's a great price too! Other manufacturers will charge quite a bit more for a laser at that power level.

When did you order yours again?

Re: My review of the SciFi Lasers SF501b 1.5--1.8W I'm glad you like the pictures! They're probably better than the videos anyway. Other members have produced far more superior videos. I don't know if it's my camera or if it's just me.

You might be disappointed to know that the items in order from left to right are: A flip-phone cell phone that cost me $5 and will be obsolete at the end of this year, a white ball point pen, a silver mini-mag flashlight (AA), and an upside down eyeglasses case.

Here’s my review of the Sci Fi Lasers SF501B 445nm blue 1.5—1.8W laser. It’s my first review so I hope I end up doing a good job of it. I ordered it on Feb. 27th and it was shipped on March 9th and I received it on April 1st. So, a month and 3 days. Placing the order was pretty simple and...

Skype? You'd have to help me with that too! :) Never done it before! Maybe you could do a video for youtube. You said it takes about an hour. Maybe you could do a video in 4 parts. But I imagine having to explain everything you're doing (especially to a novice) would increase the time...
