I was thinking of messing around with titanium and bronze, not anything crazy but certainly unique. I can't say I'd use them for a laser host anytime soon, maybe the bronze though. When I have extra time on my hands I'll come up with something.I like copper better than brass for heat sinking, but I would be fine with brass battery holder and focus knob. I'm interested in what you have in mind with exotic alloys.
From the three laws of thermodynamics, heat can be moved from one body to another without doing macroscopic work by conduction, convection and radiation. Heat will move from one body to the other when they are in thermal contact until an equilibrium is reached. Primarily what we are interested in is radiant heat. The rate at which a body emits radiant energy is proportional to the fourth power of its absolute temperature, also known as Stefan's Law. P=sAeT^4, where P=power radiated by a body in W= watts, s=a universal constant, 5.6696 X 10^-8 W/m^2, A=surface area of the body in m^2, e is a constant called emissivity and T= absolute temperature in degrees K. As can be seen by this equation, the radiant energy is independent of the material it is made of. So, it would seem that heat is moved into the air from a body simply by its surface area and not because of its ability to conduct heat into or out of it. If you have something more to add to this or to counter it, please show me.
Yes, I could do that, only the bigger one though (14500 battery bay) since I don't have any 10440 tail cap switches left. Do you mean knurled, as in the decorative pattern? If so, I could give it a try. The black material is a carbon fiber wrap BTW, it's hard to see since the image is small.Also, would you be able to make something just like the brass hosts in your uppermost right picture on the OP but solid brass with perhaps a kneeled midsection vs that black material? If so, I may be interested in about a month.
