Building an ER collet chuck Part 1
HTML-код
- Опубликовано: 17 дек 2015
- We start to take on building an ER-40 collet chuck for a 9" Southbend lathe out of a hunk of 1144 Stress proof steel. In this episode we show the differences between the ER style collets and the 3C collets the Southbend uses and a few of the benefits and we start the boring on the chuck in preperation to cut the spindle threads Also trying out some picture in picture camera stuff so let me know what you think.

Great project. Looking forward to watching the rest of the episodes.
Thanks. I enjoyed the discussion on collets. Great shot of internal grooving.
Hello I really enjoy your presentation, it is crisp and you have a great voice for recording. Thanks
Great video, well shot and narrated. Thank you.
Another advantage of ER over C is the ER has two angled bearing surfaces instead of just one. This increases the purchase and clamping force on the part.
Yup you're right. These things have a hell of a grip.
This project is a good idea and you have made a nice start. Thanks for sharing.
Coming along nicely.Looking forward for part 2.
I've been on tenterhooks since the last video, and i'm so pumped for this project. I've recently got my first lathe, and I'm so excited to start making stuff with it, including some cool shopmade tools like this one
Best place to start off is learning to grind some toolbits. Mist of us out on RUclips have a video of our own personal way of doing it. I have one on this channel available in the beginner video play list.
I like the video thanks,,, I have made one last month also I have had to make the nut itself it is a little bit tricky to done but that was fun I have made three set for wooden rotary CNC also, And it works greatly.
I had a lot of difficulty with runout on two chinese ER 32 collet chucks.
I found the problem to be in the chinese nuts.
I curred my runout issues with a "Bearing" type nut.
I bought off ebay for a reasonable price.
Near "0" runout
Also the lock up with the bearing nut was much easier with the bearing type nut
Thanks
Really liked . You did great video
thank you for the insight on tge collets, ive been kicking around which set to go after to use between the mill and lathe. and you just kicked the 5c's out the window, though spin fixtures and what not would be an easy add on running 5c.
Just picked up some Silver and Demming style drill bits (reduced shank) from Drillhog; 9/16 to 1". Games Green has reviewed them. They work well and were only about $60 off ebay.
I made and ER40 chuck for my Atlas/Craftsman 12x36. Works well. I made mine for milling cutters to use the milling attachment. I find I use it more often than I expected.
I'll have to check them out. Thanks for the heads up!
good video. thanks for all the explanations
Looking forward to this one :)
Nice and on to part two.
Nice job some nice finishing cuts you getting there.
Thanks!
i am planning on doing a similar project for a pool cue lathe i am building (my 46 logan 820 does not have enough bed length or bore size.) but the collects are going to be delrin or some other plastic. this will be a great help thanks.
nice part 1 ready 2 .
Thanks, great video. Question on your tooling. You are using insert and getting good finish. I thought good finish with carbide needs high speed. Does your South Bend go over 500 rpm? My 13" Le Blonde peaks at 500. Can I use carbide? Thanks
Great vid and great explanations. Thanks!
Did the material cost mentioned include shipping?
Cheers & best regards.
Cool project! Would like to do this one too!
I have a big junk of 3 inch 4150 I could flame harden it?
if you make your own draw bar 3c collet its 5/8 26 thread hard to find tap
Like the Video and the way you explain your steps. Did you make your dial gauge stop block? Do you have a video on it's making?
I made it a while back before I had a mill. I paid for a night class at a local tech school to get some mill time and made the block and the fingers for my steady rest so I do not have a video. I will be making an improved version for the 13" lathe so stick around.
Nice set of drill bits? Please, I still need to get a lathe, mill, standing drill, etc... (I.E. I'm starting from scratch) 🤣
You are not the only one. I am addicted to these videos.
Oh my God I can dial in a 4 jaw Chuck pretty damn fast but that's got to be the coolest trick I've ever seen. So let me get this straight first you find the low then the high and then the nearest jaw to the mid-range set that is 0 and then go around and set the rest of the Jaws to zero?
One thing that is hard to find out is how many and what sizes do you need in ER32 collets to span from say 1/8" to 3/4" and cover everything in between in 64ths? I know I could figure it out but ... Will a set in 1/16ths do it? Are they really all metric but just relabelled in imperial?
This is some time later I admit but no they are not all metric. If they are labeled in inch they are in inch. I have some metric stuff that simply won't fit in any of my inch ER-32 collets.
where is the plug gauge video? Nice work!
Good video. Interesting that your ears are a measuring insturment for speeds and depth of cut. I have much better hearing than eyesight, and I hear chatter, howling (resonance/harmonics) long before I see them.
Yeah you can usually hear the chatter happening. You can also hear rubbing really easily on boring operations. A lot of times the camera picks up a high pitch squeel during boring that I cannot hear over the machine itself.
what is that music?
I read the comments and noticed nobody corrected you on ER collet use. The collet is snapped into the nut and then screwed into the chuck and the workpiece inserted in the collet. If done the otherway could damage the unit. This is a good subject to show and I'll be watching intently.

can you start telling type an cutter you are using
what do you think about using 4440? Cuz you can always throw it in a hard wood fire pit, let it get Cherry Red and pull it out, your done
It will warp slightly and you will have to grind at least the bore.
Greg,
Nice job! Why buy tooling when you can make it, right? There's nothing like building your own Christmas present! More comments in Part 2..........Dave
Awesome. Can't wait for next video. Would you be able to share the ebay link to the stock you bought?☺
The seller is maverickmark66. Just do a search for that and his items should pop up
ER40 collets are available to hold up to 30mm.
2.5 inch 1144 is 65 bucks for 10-12"online metals
What insert is that?
Seco ccmt32.51
Hi Greg, again a nice vid. You are mentioning your email address as the best way to contact you for questions. Did I miss the address or didn't I looked properly.Teun
I have to edit it in and I forgot to. It's halligan142@gmail.com
5 collets can be bought soft and bored ...harded ones can be bored also rockwell is not that deep ir hard there is a article in home shop machinist on how to make a 5 c set up for the 10..12 inch atlas/chraftsmann/clausing/southbend/logan lathe
ER's also have the self ejecting feature and unlike 5C tighten from the nose so no draw bar/nut or cam needed.
nice shirt :) ... try to post a technical drawing before machining part:)
Be carefull with heap material its proberly chinesium
Good video, but I do not like that steel your using, The finish cuts look like a poor quality of steel
yavaş konuş biraz yaw, biz de anlayalım :)

Cool project! Would like to do this one too!
