Bench power supply is one of the best purchases I've ever made since getting into this hobby.
Wow that is a ludicrous price. Most of us could flatulate a better design. Based on what I see immediately in front of me I would use two of these mk2 3d printer bed plates. Put them in series. https://www.amazon.com/dp/B01HPXA8EC/ref=cm_sw_r_cp_apa_O.vjybW7MW53F then I'd take my shittest power supply set it to 24V and maybe some constant current at 500mA to 1A and see how hit it gets under the aluminum. https://www.amazon.com/dp/B00O8DJ8QC/ref=cm_sw_r_cp_apa_ndwjyb2N27R1A
Best part you dont need a controller cause even that silly $1000 device is only giving you a adjustment pot. Then if your wife changes her mind you can start building a 3D printer.
Go to harbor freight and treat yourself to one of those laser aim non contact thermometers too. You'll marvel at how much money you saved and how even the heat is.
Gesswein is Canadian, as is Caswell.
Not knowing where you are, I suggest you searching for a jeweller's supply shop.
In Vancouver there is Lacy West.
I'm pretty sure Rio Grande and/or Ottofrei will ship those chemicals to Canada.
Edited to add, I purchased this power supply from Amazon.com with no problems.
I can't respect a video where someone shrinks their tubing with a lighter. Get a heat gun you savage!
Personally I started to make a bench supply out of an old ATX power supply (though I was just going to provide 12 and 5v outputs and deal with stepping it down externally) when I came across a good deal on one of the cheapies like this. A project is nice but I had other things I wanted to get to where this would be helpful.
