Nice one Celso. That's almost exactly how I made mine. I didn't get the clearance angles perfect but it was acceptable in use by grinding a bit of extra clearance on the insert.

That worked out good!

The easiest to do is a sliding lid , I make my boxes with half lap joints doubles the glue area , and a half lap for the lid into a groove cut the grove off from one side , and the sides should line up .

Ready made boxes. :med:

You may also need one of these to fit your micrometer in it  :lol:

Amazon for the tiny hinges? Most of my wooden-boxed tools have little hooks & eyes, these are really hard to find, but a search on Amazon/eBay for "Dolls house hooks" brought up some likely (if not particularly elegant) candidates.

Muzzerboy:

He was probably using the capacitor to help shift the phase on that leg of the circuit.  I don't know how much it would shift it, it's been WAY too many years since I did any calculations like that, makes my head hurt just thinking about it.

I did something similar about 25-30 years ago to test a PLC interface for some 3 phase power monitoring equipment when I only had single phase available in the shop.  I used the inductance of a 1000' spool of wire to shift the signal to the monitoring equipment.

A ground fault detector (GFI or GFCI in N America or RCD in Europe) checks to see if the sum of the L and N currents is zero. It should be zero - if it isn't, it means that some current is finding an alternative path from L (or N) back to ground. So yes, if you connect a bulb from live to ground, this will be testing that the GFCI / RCD is working ok. Modern "split circuit" consumer units have 2 separately protected circuits so you can connect the lights to one and your loads to another. Then, when you trip a power circuit you aren't left in the dark. Very clever.

If you connect a load from L to N, this should not trip the circuit. However, this won't do a whole lot to create a third phase. The only reason for fitting a capacitor like that would be to adjust (improve) the power factor when you have a large inductive load. It doesn't help the load to work better but it can mean you don't pay so much for your power. I'm not sure the guy really knew what he was doing but as I said, I couldn't be arsed to watch the whole thing.

I have few tools that came with cheap plywood boxes and were DOA.

One will need practically all new innards, cheap box, cheap taping head set, probably will hack up something to suplement rigidy or dump contents into plastic box....

But there are some tools that deserve proper box.

Saw this:


But hinges and hardware that is available on local hardware store is outright ugly. I understand that to mount the hinges inside (as is tradition) would demand more wood or tiny hinges.

And those locks/clasps, they are getting worse and worse every ear. I don't like magnets near my tools. I have made a jewelery box that had magnets, they worked fine, but not near my tools.

Suggestions?
