I ordered a set to try too. Thanks for the heads up Bort. 
Pilot,
Thanks for posting about these. I would have been skeptical of the quality had you not given your stamp of approval ( which IMHO carries a lot of weight when it comes to any of this kind of stuff ).
Hank really has an advantage over many of the other China dealers if you ask me. First off his English is a lot better. Second he truly understands the market. He knows how to get the QUALITY up and still keep the prices down.
I hear you guys:)
Right now there has been a slight delay of progress on this because the half nuts on my lathe wore out again ( you need these for cutting threads) I will have to either order another from china or find a way to repair the old ones.
Meanwhile I may look around to see if I can pick up some of the lights people are asking about, that way I can get the pill in hand and decide if a run of copper slugs is doable.
I probly wont start a feeler thread for them until I at least get the lights in hand.
I do love your enthusiasm.
Again, said it before, I'm in for at least two HD 2010 copper pills! Understand though, VOB, take good care of that lathe, we don't want to burn it out any further!
not sure if this helps, but I saw a very neat thread (ba bam!) on homeshopmachinist a while back about making your own half nuts. I can’t remember the exact process, but the gist of it was to use some delrin tube cut in half length ways so it fitted within the metal shell (?), then clamped around the lead screw (or equivalent rod with same pitch and diameter) which was then heated with a blow torch while clamping down on the delrin. By the looks of it, the delrin softened enough to form into the threads. It’s a bit hazy I’m afraid, which isn’t helped by the fact that my lathe doesn’t have a lead screw (or half nuts!) so it’s a somewhat magical dreamed about lathe part that I don’t understand.
Either way, it sounded pretty neat 
if I put solder in the hole of the sinkpad will it be better than heat conductive paste??
does the 2 degrees higher temp make the sinkpads a lot worse?
You won’t notice any difference in real world application georgek.
It’s theoretical maximum temperature at some spot that has 2°C difference in the theoretical model.
Sure flat is better but it’s not like going from Aluminum to Copper :bigsmile:
The same can be said about having and XM-L at 2.6A and at 3A, no real difference in real world application...
only about 100 lumens, shining it on your wall won’t matter much, but outside 100 more lumens makes slightly more difference
I don't shine lights on the wall... I only care about outside but that is not the point.
i agree with your original point that the sinkpad vs noctigon won’t have much real world difference, but your 100 lumen less example i disagree with
I concur with Bort. Just fill the void of the SinkPAD board with a CPU silver paste and that’s it, or solder it and then polish the bottom flat.
but these noctigons are two for the price of one sinkpad. and with better thermal design, it almost makes me wonder why anyone would purchase a sinkpad again
not saying toss your sinkpad and buy the noctigon, but just makes sense for future purchases
Exactly. Makes more sense for future purchase since they are cheaper and “better”.
However, cost aside, both will function with relatively little difference. I think the analogy of 2.6A vs 3.0A is a flawed comparison. There is a noticeable difference there.
I was trying to say let's not ignore a small difference (2Celsius), mostly thinking on the number itself 2.6 vs 3, not the current itself 2.6A 3A. I was ironic in that post. I actually like to get the best out of everything, like AR coated lens even if I gain only 5% more light transmission, that 5% is not a standard of course, quality of the AR or single and double sided ca make a difference in gains, or even poor uncoated original can make a higher percentage gain.
Depends how you get your SinkPADs, but yes they cost something usually.
Anybody knows a website of Noctigon? Couldn’t find it.
Well sure, so they also got a manufacturing for direct copper boards? Interesting.
I also like the fact that the noctigon is easily available, and a good price, but the gold will reduce performance slightly, i’m not sure by how much though but i do hope its negligible, but it is possible the sinkpad may have a slight advantage being all copper, but i still agree that real world performance should be comparable between the two.
I thought only the solder pads were gold plated?
Either way, the results show a slight edge to the noctigon
