Re: collets:

ww_big_al
 

The ER40 collets do not have a gap in their range. There are 29 collets in a complete imperial set. Most “sets” sold are not complete. I had to purchase individual collets to make a complete set. What I like about the imperial set is the collets overlaping ranges so I can select a collet in it’s middle of the clamp range.

About the ER collets, each collet covers a range of 1mm. I use ER 32 collets because I found them on sale. I wish I had ER 40 collets because they go bigger. The ER collets go from the printed size down 1mm. Never put a bit or stock bigger than the printed size into an ER collets because it could distort the collet.

The ER collets hold bits/stock over a longer length than a 3c or 5c collet, giving them a better grip. The modestly priced sets will give you 0.0003" TIR which is pretty good. Do to the range they will hold, you do not need an exact size. Nothing wiggles I'm the ER collet like it does in the 3c or 5c collet if the size is not perfect.

I purchased both both a square and hex holder, and a lathe chuck that mounts on a backplate. All pretty reasonably priced.

I use one set of collets for both my lathe and vertical mill. While I have both imperial and metric, I have only used the metric set because it gives me complete coverage from 2mm to the top of the range. The imperial set has gaps that exceed the 1mm range. I simple measure the bit/stock diameter in mm and chose the next integer size collet larger if it is between sizes.

Just my experience...

"Complete set"; are you sure you want or need 1/64", 1/32" or 3/64" collets? They're in the set. My first size either 3C or 5C is 1/16" (well, I do have a 5C 3/64" but I do not anticipate using it any time soon!) Sets of 3C's also include hex and squares (something that the ER series can't handle). Obviously more collets in 5C, as they go up to 1-1/4" or larger with closers and such. The typical max 3C (also 1A you will find interchanges easily) taps out at 9/16".

There are standard metric sizes and the are decimal sizes by thousands. A "complete set" is crazy expensive in 5C and probably unobtainum in 3C/1A.

Here's my (mostly complete) set:

JohnB: exactly right on the grip range.  Go watch youtube video from Joe Pi - he covers collet grip issues, and explains it very well.

 

BTW, for the original poster of this topic: If you have 20 3c collets, you may be close to having a full set.  I rarely see a lathe with more than 15-20.

Number of collets to cover a given range is dependent on the grip range of the collet.

 

5C do not have a very wide range.

 

I think the ER series has a wider grip range per collet than the 5C.

Re: collets:

        I think theres different sets & they go by what the fraction size is . so you may have a set of 16 in 16's but not have the 32's between the 16's which would make a 32 piece set if that makes any sense . I remember reading

        somewhere that the guy said to get the metrics in the ER's cause there is a better grip range . But I could be totally wrong on both accounts

Long story, so forgive me.

I had an early 405 9’ Workshop. it had a “Top Oiler” headstock, I Changed this out to a later side oiler. While I was doing thisI also used a 10K spindle.
(Yes the 9” Workshop and 10K have the same journal dimensions.)

The primary reason, at the time, was that the 10K spindle has a slightly larger bore. 55/64 vs 49/64, or 0.860 vs 0.766. This is enough to add a lot of versatility.

IN ADDITION the 10K spindle will accept a SB proprietary 6K collet. It does this without any adapter. These allow one to hold 5/8 stock through the headstock as opposed to the upper limit of 1/2 THROUGH THE HEADSTOCK with the 3C.

6K collets are expensive and rare, I took me about 8 years to collect a complete set. I can go from 1/16 to 5/8 in steps of 1/64.

I highlighted the 1/2 THROUGH THE COLLET because there are some 3C collets larger than 1/2” which, have an internal step bore, and allow you to insert material to a depth of about 1”.
I had them in steps of 1/64 to 9/16” at one time. I sold my 405 some years ago, along with the larger than 1/2 collets.

One thing which has not been mentioned. Is that the 3C/5C/6K collets are available in in botjh square and Hex. Not so with the ER’s.

I use 5C on my 10L and I do have some hex and square collets. I find them quite useful. I do have and ER-40 setup, but I mostly use that for odd size work, since my 5C’s are incremented in 1/32” steps.

I do miss having the 1/64 steps of the 6K’s but while I still have the collet set, I don't have a Lathe to take them.

One other note. The ER’s with their adapter stick out beyond the spindle 1.5 to 2”. I don't care for that.

mounted so that the top surface of the swivel bar runs flat and true to the
ways of the bed (there is some play in the mounting holes in the bracket
to allow some minimal movement for alignment).  Once the bracket and
swivel bar are set and running true, one is to drill and ream through the
pin holes in the bed bracket into the saddle and install the two 1/4" x 1"
pins.  Then, if you choose to remove the taper attachment for some
reason, you can use the pins to relocate the bed bracket and avoid the
necessity of re-aligning the bed bracket and swivel bar when re-attaching
the taper attachment.

Good Luck!

5C collet closer

Ruth Busch
 

I purchased a 1958 South Bend 10L that came with a set of 5C collets.  The lathe has a collet closer lever that mounts on the left of the headstock. 

 

How should I be using the collet closer?  I noticed sometimes when I adjust the closer knob and pull the lever to tighten the collet, it will sort of snap and the stock seem firmly gripped.  Other times I cannot find the snap and grip point when I adjust the knob and pull the lever; this causes me to question if the work is properly gripped.

 

What is going on?


9" Taper Attachment

Hi, Folks,

I have a taper attachment that is missing a minor part and a couple of bolts and washers. I've "finally" decided to complete it and to install it on my 1946 9C. (The missing piece is a simple steel block with a tapped hole to clamp the fixed end bracket to the lathe bed. I figure 2" x 2.3" x 0.5" should do it.)

I've looked at several videos on Youtube, including Tubalcain's TIPS 561. He showed an exploded parts page.

There is a pin on the fixed end bracket. I cannot figure out its function.

A. Anyone got the SB literature on this thing?

B. Do we have a library somewhere? I've never tried to access it.

Thanks,

Dave
