Thanks...that was so easy.

There is a good set of step-by-step installation instructions.

Webb, do you have Form 906L in electronic format? I'd like to have a copy.

Can you give more information?  I have looked at two parts diagrams

I don't see any "pin" in the "end bracket" (SBL part no: AS864NK1).
 
Are you possibly confusing the "bed bracket" (SBL part no: AS862NK2)?
This is the bracket that bolts to the back of the saddle.  There are two pins
that can be used with it (SBL part no: 160X82) which are 1/4" x 1" long
straight pins. 

When attaching a taper attachment to a lathe, the bed bracket should be
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.

Re: collets:

mike allen
 

        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.

Re: collets:

Nick Andrews
 

Thanks!  I just got a set of 29 ER40 collets to use in my SB mill and this chart will be helpful for me.  I ordered a couple of tool holders to use them with to better grip random-sized mills or drills since I only have a couple of 3/8" and 1/2" BT30 tool holders but a sordid collection of cutters. I was debating if I should buy a set of metric collets too.  Figured I could get a collet block to use them for holding work in the vise or on rotary table as well.  Or in the shaper vise.  My Sheldon lathe came with a few 5C collets, but I haven't made a collet closer for the spindle to use them with yet.  While I may buy more 5C collets, a ER40 collet chuck for the lathe might be more useful and at this point cheaper.

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?

Re: collets:

Rick
 

I have both a SB9A and a SB13.  I have both 3C and 5C for each respectively.  That said, I also made ER40 collet chucks for both lathes.  This lets me use larger sizes on the SB9, and better grip range with much less collets.  They are slower to use than 3C or 5C, but not really an issue in a home shop.  I have also made collet blocks for the ER40 to use in my milling machine vise.


Re: collets:

Thomas Harrold
 

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.
