Details on WW Collets for work holding in the Sherline lathe and explanation of R8, 3C, 5C, ER16, ER32, ER40, and all the various identifiers for collets. - Jak na to + styl
I’ve purchased that Collet set + added on several of the very small ones for making my very tiny 1:25 scale model parts… INCREDIBLE TOOL HOLDER🤩🤩🤩🤩
Very good video.
I have to point out ww collets full set 900 dollars. Dial indicator and 4 jaw chuck anywhere from 100 to 300 bucks. The collets are nice and I see the appeal. However, it really isn't that much more work to measure. I agree with you the only real reason someone should entertain collets is if they are turning out repetitive parts. Personally I machine firearms for personal use (its a hobby for me) so there is really no reason for a hobbyist to get them unless they start a business.
Great information here and you speak very well and try not to linger on any one point of discussion which makes for a highly informative and very well laid out video. Good job.
Awesome video Sir
Another excellent video............Thank you.
Also your new website looks great! I like seeing a "place holder" for projects and am looking forward to seeing where you go with that.
pro trick : watch series on flixzone. I've been using it for watching a lot of movies lately.
@Quentin Kayden yup, I have been watching on flixzone for since december myself :)
one thing you Don't say is that the spindle nose is an M0/1/2/3 taper standard!, this is the why for the adaptor at the chuck end, to adapt this Morse taper into the angle the collet standard is, R-8, ER-16/32, NT or cat 30/40 etc. it is THIS taper which closes the collet, so needs to be right for the chuck screw thread taper, so it clamps down BEFORE the collar on the collet chuck bottoms out. (what is shown here is for Micro machining, you don't normally see this drawbar style, except on watchmakers equipment, their mills (rotary heads) and lathes, ie 6/8 mm boley, Lorch, Schaublin, and of coarse sheerline) what you normally see is this taper inside a drive centre, which forms part of the chuck body, the NUT provides the closing force, or a drawtube with a cam lock toggle lever (aka the Hardinge style), or hydraulic/electric slave cylinder, (the 'swiss' cnc machines, HAAS, and others).
There are lots of chucks that work with ww collets or even have them directly addapted for sherlines and unimat and watchmakers lathes.
Can someone please explain the concept of runout? Also can Sherline and it's WW collets capable of turning a watch balance staff?
Taig offers an adapter for $30 that screws onto a 3/4-16 spindle with an ER16 chuck on the opposite end.
Sherline bought out Taig several years ago.
Another excellent video for the Sherline equipment owner💯💯 .
I also noticed that my WW Lathe Collets set fit the Mill (making total sense since it’s same headstock) but in all honesty, I PREFER the LATHE attachment DrawBolt with the Knurled
Round Hand-Tightening Knob -vs- what you get with the Sherline into Mill Collet set. [U know what I mean]??
👉For the life of me I don’t see ANY REASON why the lathe collet setup would be harmful or a long term issue for use…Can U?
👉BTW: I just noticed the QCTP “A2Z” that your rocking in a video. Can you please tell me where you purchased that, cost & if your happy with it. I’ve purchased just about EVERYTHING as far as attachments & tools for my 2010 Mill & 4100 Lathe with the exception of the Sherline’s QCTP very expensive attachment😉
Again Great job on All your videos, U R MY GO-2 Source for Sherline machine info💯
Cheers

AtoZ went out of business several years ago in case you haven’t already found out. Little Machine Shop has a QCTP (OXA size) for the Sherline lathe.
HI IF YOUR @ .0015 R.O. BY THE CHUCK ------ WHAT' S YOUR R.O. BY THE END OF THE PIECE ? THIS COULD BE CAUSED BY THE DEPTH OF THE SHORT COLLET C.BORE LIMITING CONCENTRICITY GRIPPING FORCE. I'D REALLY BE WORRIED WITH TRYING TO USE THAT TOOL LIKE THAT EXTENDED END WITH ANY KIND OF WORKFORCE TORQUE / CHIP LOAD AGAINST IT JUST MY THOUGHTS MIKE G.
3:29 i see the endmill moving 👀💀
I would be choked if I was seeing .0015 runout on a collet.
Stupid Kills !!! ..How True
.0015" is not minimal. That is a mile in machining terms.
