Lab Power Supply Update

So i got in and did a bit more work on the lab power supply. Finished off marking out and drilling every hole for every component so i do not have to go back and make a mess inside when i start to wire things up. Other than 2 tie bars across the top, the lower half of the case was done in the image below.


Mounted the switch mode PSU into the case, its held in with 4 M5 bolts and is not going anywhere, the fused, switched power connector and EMI filter are also bolted in with M5 bolts. The earth wire will be bolted to the case also with M5 bolts as well as serrated washers, so it cannot go anywhere. Go over the top on safety is my motto.


Mounted all the front panel items. From here its now just a matter of wiring up the spaghetti and making it all work together. But that will be another day, i do not think i have any wire suitable for 240v ATM and will need to go and get a meter of 3 core to pull apart for the internal wiring.


Homebrew Bending Brake

So there is this channel on youtube that i like to watch, Old School Forge by Chandler Dickenson, he is a blacksmith and a bit of a funny bastard to boot. Here is a link to his channel have a watch: anyway he has a saying Need A Tool, Make A Tool and I am currently in need of a tool, that tool is a bending brake for think stock aluminum sheet metal 1 ro 1.2mm thick.

I went looking on line as well in the local retail chains and they wanted over $100 bucks for one and well, i am not building the Taj Mahal or anything that good, so i figure I will make one out of either crap i got laying about or whatever i can find at the local bunnings. So $20 worth of 3mm mild steel angle, and $5 worth of hinges and some bolts and clamps I already had laying about and boom, we are in the sheet metal bending business.

It has an opening just a tad over 300mm and that is wide enough for anything I will ever want to bend, mounts in my vice on a bit of old scrap pine 3×2 and is accurate enough for the kinds of bodgey jobs I am making. Which currently is a lab PSU with 3 channels. Anyway that’s enough gabbing, time to go and do some more project work. And remember the motto, Need A Tool, Make A Tool.

I should also mention, to get the hinges to sit flat, you need to pop the pin out and flip one side over, other wise your crap will not sit level.

A small update: IT WORKS.
