Cooling is a GO

Cooling - connected and flushed

I got the new fittings and hoses hooked up then flushed the water chiller and the induction heater. No leaks, cooling is a go!

Cooling - New metal base for cart

Before putting it back on the cart I replaced the top plastic liner with 16 gauge sheet metal that I cleaned and lightly wiped down with oil. I think I’ll go back and add a lip around 3 sides with the box break to catch any falling sparks and molten beads of metal that try to escape.

Back on the cart!

And here it is with cooling set up on the new cart.

Now to move on to power. I am making a quick disconnect near the breaker box. I will need to draw and 3D print a small enclosure for the 3/8″ dual splicers. More on that progress here.

Hooking up cooling water and power

Hooking up cooling water - parts laid out

Hooking up cooling water, but first, fittings!

One trip the hardware store later and I’m ready to hook utilities up to the induction heater.

Hooking up cooling water isn’t the only step… Power!

I also ordered a larger variac, a 5000VA 220V model to aid in testing and firmware optimization. I have a small 2000VA 120V variac but running it on such low voltage skewed a lot of the readings. The variac is nice because running full power while testing new features can a bit nerve-racking and wasteful.

Reactor Forge on the Bench

Reactor Forge on the Bench

The Reactor Forge on the Bench and ready to hook up!

Reactor Forge on the Bench

This new rolling stand from SAMs club was perfect for holding the Reactor Forge, Bernard Weldcraft 3 gallon water cooler, extra bricks, and coils. I just need to replace the top plastic insert/mat with a piece of sheet metal. 

High-level action plan:

  • Publish existing mechanical specs, unit wiring schematic, core control board schematic, to Atmel C code to Github.
  • Add my current issues and changes that need to happen to each of the above topics in Github for proper tracking.
  • Work on those issues, changes, and improvements.
  • Make the next version, test, refine, and repeat as needed.
  • Work on BOM supply chain.
  • Kit logistics: work on which parts will be preassembled and which will require user assembly.
  • Create and publish a kit manual.
  • First test kits for users, feedback, etc. etc…

What’s next after getting the Reactor Forge on the Bench?
