Re: Making an ER40 Collet Chuck
$50, that is cheap.? So far a back plate, would you get one with pre drilled holes?
Having to drill holes i would be worried about locating the holes precisely enough. Hopefully the chuck works out and is accurate. -Jody

I just ordered one of these chucks from ebay. 45 bucks coming from china. All machined ground and hardened. Will it be good? Dunno. We'll see.
My $0.02 is that building a kiln to heat-treat one part (made from material not designed for heat-treating) is a fool’s errand. But O1 steel and harden it or just buy the needed collet.

Re: Making an ER40 Collet Chuck
Andrei The chuck you bought from directimports is sold out now. They could not answer me what the OD of the nut was. Just make sure you watch the listing of the chuck when they claim its back in stock the chuck will be double the cost.? They did that with a propain? torch? i wanted to buy. GP

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.

Re: Making an ER40 Collet Chuck
If you only do it once, you're probably right, though you don't have to make a really fancy furnace to do it. The video shows one that is essentially a pile of fire brick, and can be taken apart and reconfigured for whatever you might want to do with some firebricks and a torch. I have 4 firebricks, a chuck of the bottom of an old drop-in fireplace a neighbor asked for help removing from his hous a decade or so ago, and some pieces of an old kiln my son bought to do ceramics work with that turned out to be too power-hungry for our vintage 1963 house. It draws 60amps at 240VAC just for the kiln proper, not counting the additional ring. My whole house entry panel is rated for 60amp at 240VAC. In addition to a Turbo-Torch, I've got Michael Porter's book on Gas Burners, and a couple of 3/8" Mikey burners he sent me the parts for some time ago. It would be a cinch to put together such a furnace, use it, and tear it back down.
I'm considering putting a couple of 1" or 1-1/4" Mikey burners in the hulk of the kiln. I's sure I could do all sorts of interesting things with it.

Re: Making an ER40 Collet Chuck
We had that discussion, actually. Guenther thinks it is, and offered to walk him through the process. He's a professional machinist, so he defaults to making it for long life, and for his purposes, he's absolutely correct. Andrei, IIRC, suggested it could only be done in a high-cost professional carburizing furnace. I referenced older information from an older and also very professional machinist from a somewhat earlier time, who described ways to do this sort of work with simpler equipment, and Jody has the info he needs to make his decision. Personally, I'm not saying he has to do it, just that it would be cool if he does, and it would last probably more than a lifetime. I did say if Guenther is willing to walk him through the process, Jody should take him up on it. It would be a great skill to have! Guenther has a lot of experience, and is a tremendous resource for our or any group.

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.

I have a different theory on socks. We are all familiar with the missing sock at the end of the laundry cycle. Ever notice when you open the closet door that you seem to have half a bazillion extra clothes hangers?

The lighter is stolen, the thief goes back to the third

Re: Making an ER40 Collet Chuck
My last f150 died at 295k because i tore up the underside and it was not worth fixing. My current one is at 189k and drives like i bought it yesterday. It is all on how you maintain and how you drive it. Like any tool, if you take care of it she takes care
of you.
The pre 2013 duramax diesels are legendary. After that, not so much. I found fit and finish to be better on fords. Back in the 80s was the other way around.
Sorry for the thread hijack. Staying quiet now.

No hardening is not necessary, That is if you want to make a new collet chuck in a short time of use. My comment do you job right or don't do it at all.?

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?

No this is a misnomer. The missing items are stolen by creatures
from the third dimension.?
The most well known issue is with cigarette lighters which
are almost always lost then found empty. Butane, as everyone
knows, is the gas in the lighters and is of course the most
popular currency in the third dimension. Second only to spare
house keys.?
The lighter is stolen, the thief goes back to the third
dimension and parties it up usually wearing a stolen left sock
as a further trophy of the thief's bravery and skill. Once the
butane is depleted the lighter is returned in the hope that the
lighters owner will find it, realize that it’s empty and buy
another one.
Only left socks are taken for obvious reasons.
Missing small metal components are taken and used as
Christmas tree ornaments which is a bit peculiar since
Christmas isn’t celebrated in the third dimension (the
“Trinity” concept confuses them).
Whit?
PS not sure what this has to do with lathes or machining
stuff but since you asked.

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!
