There seems to be an assumption here that hardening is a requirement for the project. I'd like to play devil's advocate here and ask - Is hardening really necessary? Desirable sure, but necessary??? If this was a tool that was going to get constant daily use in a commercial machine shop I would say definitely yes. But in the home shop where tools get relatively minor use, I think we can get away with not hardening.
I'm just an amateur home shop machinist with not all that many machining hours clocked yet, so I may well be off base on this. What do you more experienced hands have to say about this?

Re: Making an ER40 Collet Chuck
Andrei, No I did not. at the time I had no idea what brick molding was. and they were darn cheap.? So I bought them off Fleabay. later I found the moulding had I known? I think I would have built them myself. Not really to save the $$ but for the personal fun. same with the nut and wrench too cheap to make imho. ?

The mystery of why it is so hard to find dropped small parts is a
long- standing one, but I am going to reveal the answer her based
intensive science experiments I recently concluded. The reason I
embarked on this research program was due to an experience I had
while working in a small breakfast room next to my kitchen. This
8' x 10' room had a hard tile floor, and nothing in it but a table
and chair. I was using the table to assemble a computer and I
dropped a screw. I distinctly heard the screw hit the tile floor,
but when I looked for it I couldn't find it. The floor was divided
into squares by the tiles, so I got down on my hands and knees and
searched the entire room tile by tile - no screw to be found.? I
called it quits and left the project until the next day. When I
walked back into that room, there was the screw lying in plain
site in the middle of floor!
This prompted me to enter into a series of experiments using high
speed cameras, lasers, special lighting arrays, and a plethora of
nuts, bolts, and screws. It took me a while to capture on video
what was actually happening but I finally found the answer: Time
holes!
I discovered that there are extra-dimensional holes 3 to 4 inches
in diameter and an inch or two off the floor. These holes are only
open from underneath. If you drop something in the location of a
hole from above it acts like it is not there; but if the dropped
object hits the floor and bounces?up into the
hole then it disappears! But the object doesn't go out of
existence because these are time holes; the
dropped object actually bounces into the hole and into
the future by several hours to several days, depending
upon how "deep" the hole is. This is why you can hear a dropped
item bounce but then it's nowhere to be found, only to turn up
later. The time holes are also sensitive to light so they fade
quickly in the open, and are more likely to be found under tables
and workbenches.
Isn't science amazing!
