yes this ^^^^ @Airwalker16 the nuts bolts and washers are for the eye bolt which IS for hanging the heatsink.@Airwalker16, the small screws with the flat rim around the head, I used to attach the cob to the heatsink, the longer ones without the rim, I used to attach the reflector adapter. the black screws , I'm assuming are to mount the heatsinks. The eyehooks for hanging the rope ratchet hangers to. lol I haven't figuered out what the small nuts,bolts and washer are for yet. Thank for your help Airwalker. Finally got two cobs mounted to heatsinks. I was overthinking the ideal holder. Thinking it would literally "lock" them in tight. Eh, not so much.
From a certain point I'm using only A2 or A4 stainless screws (credits go to @stardustsailor ). Especially these inbus ones are awesome and look great (IMHO).Its easy.

M4 7mm optional if you got reflectors or you told me you plan to use reflectors.
The M4 nut and washer also fits M4 12mm Black.
hex heads are slightly more of a pain in the ass to deal with, tracking down an allen wrench and all. but damn those SS ones are sexy as well. its the small touches that take a nice build to the next level. That and those Junction boxes that Robin makes. I hear each one is a custom hand job.From a certain point I'm using only A2 or A4 stainless screws (credits go to @stardustsailor ).

Been a long time since I had a custom hand job!hex heads are slightly more of a pain in the ass to deal with, tracking down an allen wrench and all. but damn those SS ones are sexy as well. its the small touches that take a nice build to the next level. That and those Junction boxes that Robin makes. I hear each one is a custom hand job.
I have been moving to torx screws away from Philips heads, tired of rounding them out. All SS of course.hex heads are slightly more of a pain in the ass to deal with, tracking down an allen wrench and all. but damn those SS ones are sexy as well. .
And then the pot will backstab the terminalshe assembles each one by hand while watching Game of Thrones. When you receive this junction box, you will feel the love and care that has gone in to its creation.
well you are in luck. Because Robin Told me each one is a Custom (by) hand job. he assembles each one by hand while watching Game of Thrones. When you receive this junction box, you will feel the love and care that has gone in to its creation.

Ad hoc testing with 60mm sparse staggered anodized pin fins and a tiny bit of fan cooling performs really well. The fence post idea will work.As en vogue as passive is these days, are any of you using pin sinks actively or semi-actively?
My thoughts for a cheap fence post fixture.....
Pin sinks in a 4"x4" vinyl fence post with a 100mm fan in one end blowing through it.

You could probably get away with using any pin sink with a 70mm base for a 50w cxb3590/ideal holder cooled semi-actively. I've seen some on alibaba for <$5
Quick math has me at:
4x heatsink - $30 (possibly cheaper) shipped
100mm silenx fan - $9 @frys
36" x 4" x 4" vinyl fence post - $10 @home despot ($30 for a 108" piece)
I've always liked how a 140mm fan fits nicely in the end of a 6" fence post and 100mm should fit even better in the 4". Problem was always that that orientation sucks for the heatsinkusa style sinks but it's perfect for pin sinks.
Either way I think the potential for building a very lightweight/cheap to cool lamp lies in using small pin sinks with a fan blowing horizontally through the case.
It would work better if you attached the circulation fan in the middle- and sucking, not blowing.As en vogue as passive is these days, are any of you using pin sinks actively or semi-actively?
