Personally, if I could choose a Convoy light in copper and get heavy anyway, it would not be the rather boring looking S2+ but it would be the S8 :sunglasses:
From personal experience, the Traditional Crush (pressure) knurling is very tough to do on very soft alloy’s like real copper, the soft material starts to build up on the roller blades. Turning and side broaching to produce the square knurling is a tad bit easier…
That graph comparing the XM-L2 to the XP-L is misleading, it uses an old outdated XM-L2 against the highest binned XP-L. If a newer high binned XM-L2 U4 were shown against it the graph wouldn’t show like it does. Just saying.
I don’t know anything about machining so I can’t speak to the reasoning, but I really like the new look. That “grenade grip” is very popular for good reason, and I really dig the cooling fins on the head. Gotta have a new one too I guess…
Of course, you are right. That’s why I wrote to treat it roughly. The author of the question does not give specific diodes. In fact, the author of the question referred to XML and XPL which have successors. Maybe it’s better to ignore this chart.
I have a limited experience crafting with copper, and I can say it definitively started to build up around my cutting bits when chopping a 1mm copper sheet carefully under my vise attached Dremel style multitool. This for sure has to do with its malleability/plasticity with its super high thermal conductivity. I ended up managing fine results, but took careful filing:
