Here is some recently discovered footage from 2013! Somewhere on planet Earth, a kid named Dean started building a factory. Using custom built and retrofitted equipment, I set up production of these little heatsinks in my garage. #makermade

This Brown& Sharpe #00 automatic lathe was built in 1954 in Providence, RI.

The 2016 production lot is in development. The new products include five PowerPeg sizes to choose from, as well as several heatsinks.
The quality of the PowerPegs has been improved. These threads are class 3B, which is as good as they get. The threads are also 40% deeper which means more strength, and more design freedom.
I have adopted strict quality control methods, and plan to produce around 200 of each size PowerPeg using a retrofitted Brown&Sharpe screw machine.
The pegs are #RoHS comliant; fabricated from alloy C145 copper, and ENIG plated.

I ran out of money.
In the meantime, here's a cool graphic!

This machine cuts a thin layer from the front surface of PowerPeg, making it perfectly flat.
The machine consists of a motorized clamp, and an air-powered broach. When the air piston is actuated, the copper part is dragged past a carbide blade.
The result is a curled copper circle, only 0.005" thick. The finished surface is flat and shiny.

I built this in 2012.
1) grabs the PowerPeg and spins it at 300 RPM
2) smoothly moves in a countersink from the right
3) removes sharp edges from the PowerPeg threads
4) ejects the PowerPeg
Low budget, but she's a beauty. Since the first production run we have integrated this process into another machine, so this one is retired.
It looks nice on my bookshelf. I have come to appreciate the unfinished look. It's like an art piece.

I've completed 30 blank bars with the heatsink profile. Next they will be milled and diced into various lengths.

Some circuits have a number of PCB heat sources requiring cooling. For example H bridges are comprised of four FETs. Power supplies may have many LDOs, FETs and driver ICs. LED strip lights are all the rage this year.
These heatsinks will provide an off-the-shelf part for cooling multiple components on a single PCB. They will be available in different lengths. Each length features a number of receptacles.
Many PowerPegs can be attached to a single heatsink. The heatsink effectively becomes a very 'beefy' ground plane.
The heatsink serves as a 3rd PCB layer, and provides shielding.

This design provides a 4:1 ratio of air fin surface to PCB surface.

The WC-43-A is the same size and shape as the GP-43-A heatsink. This water cooler connects to any 43 Series thermal connector.
The brass fittings fit a 1/16" ID tube.
I tested this cooler at 9.9 watts with great results. The temperature rise was only 40 degrees celsius.

This RTV microfluid circuit was made using a PCB as a mold, and casting liquid rubber onto the surface. The tiny PCB traces produced small channels which water can flow through.
This is an early prototype, but my idea is to build tiny water coolers using these rubber fluid circuits.
