I turn a Nut into a tiny Adjustable Wrench

In this video I'm turning a stainless steel M20 nut into a tiny adjustable wrench. All three parts are completely made out of one single nut. First I turned the thread and the hexagon away on the lathe. After cutting a slit into it I was able to open it up with the help of a torch. A few heats later I had a very straight and flat piece of stainless steel. I first went then on the milling machine and milled the whole part to the final width of the wrench. I then cut of a piece with the hacksaw to make the body out of it. With a tiny t-slot endmill I was able to mill the t-slot very nicely with a very low feedrate and a lot of oil. After milling the square hole and drilling the deep 2.1mm hole I started to shape the outer contour. Then I moved on by making the movable part of the wrench. I milled it all in one operation with very careful steps to not risk and chatter marks or whatsoever. After filing the square bit round I sanded the rectangular part until it fitted nicely into the body. I then cut the M2 thread and cut the piece off with the hacksaw, assembled it with the body and sanded both parts flush. Then I started rounding off all edges with needle files, sandpaper and finished it with very fine steel wool for a brushed finish. All what's left to do now was making the knurled adjuster nut. For that I forged the remaining of the nut into a square piece, which I could clamp in the four jaw chuck on the lathe. I turned it round, supported it with a live center, put the knurling onto it, drilled and tapped the hole, chamfered it and parted it off. Then it was just a matter of quickly assembling the three pieces.
This was a very cool little project for me. I really like how it turned out. It's a very cool little item in my opinion.
