Nice and well done!
Is that a Dtr 12mm copper module?
I have been skimming posts on the G8 lens and haven't seen a issue with limited threading on a module, only the G7.

Maby RedC will chime in.
Enjoy, be safe and glad it brought back childhood memory's!
Yeah I didnt think much about doing that, but remember i just bought a lathe, so I could try cutting it down a MM or two I guess?
No, its not a DTR module, its just a cheap one I bought off ebay that came with a lens but swapped out with a better G8 lens.
The part that the diode is pressed into definitely looks like copper, but not sure about the chrome part as I never filed it off to see what it looked like.
I might grab a DTR one later, as it didnt feel very tight in the host and slipped in rather easily, im not sure if the DTR ones are a different diameter or not? My main concern was thermal heat transfer, I put arctic silver grease all around it, so hopefully that helps.
I would get my hands on a G2 lens. The M140s have pretty good beam divergence specs that don't necessitate the use of the longer focal length lens. You should do fine even with the short focal length lenses offered on eBay for under $8.00 each. Unless you are trying to see the beam profile at great distances you don't need a G8 or G7 lens.
OK interesting to know, I had been advised that a G8 lens would give the best efficiency, but at the expense of not a nice tight beam.
This thing burnt my carpet about 2 metres away, so it certainly appears to be giving its full power.
If i go with a lower efficiency lens, will the beam still look as bright in the sky?
I dont care too much about seeing the bean profile at long distances, if anything, I would be happier with a more tight, round dot at a longer distance, my main concern is not loosing too much power.
It almost looks kind of like it does produce a tight beam, but has a fatter secondary beam that slightly surrounds it like a very narrow spotlight.
Im assuming this is due to the optics?
I should grab a G2 lens and see how I like it I guess. The module I bought on ebay does come with a glass lens, so I guess I should try it too.
