The 'PC' in your subject line, but not in the description in the
body, suggests that this is the later CNC version -- the one which uses
a PC as the controller, instead of having it built in, as in my
Compact-5/CNC.
The toolpost and holders which came with mine (and which have
been augmented by some from eBay auctions) happen to be identical to
some sold for Myfords, IIRC. There actually were two styles,
sufficiently different so none of the parts were interchangeable.
The one which I have has a T-slot centrally located between two
female 'V's (on the tool holder), and the T-slot is engaged by a
cam-operated T-head on the toolpost. This is the style which I have
seen offered for Myfords. I think that the maker in England is
"Dickson" or "Dickenson", but I could be wrong.
The other style is similar, but the T-slot is not centrally
located, but rather offset towards one of the 'V's, and the matching
T-nut is pulled in by a screw which passes through the body of the
toolpost, and is operated by a wrench on the heads of the bolts. (Both
of these toolposts have two positions in which the tool holders can be
mounted -- one proper for turning the OD of a workpiece, and the other
proper for boring and facing.
In either case, the center-to-center spacing of the two 'V's is
critical, if you are making holders to fit an existing toolpost.
You can also get tailstocks and other accessories from eBay
vendors from time to time -- just watch it for a while.
Note that the toolpost described is *only* for the CNC version
without a compound. I've never seen a manual version (just photos), and
am not sure how different the toolpost and holder may be for that
version.
By "inside chuck jaws", do you mean the ones which are most
commonly fitted to the chuck, which can grip the ID of tubing by
expanding outward, or grip normal round stock? Or do you mean the
reversed ones, which grip larger stock on the jaw steps?
Come to think of it -- there are two styles of 3-jaw chucks for
the Compact-5.
One is like the chucks found on larger machines, with two sets
of jaws (inside and outside), plus possibly a set of soft jaws which can
be bored for specialized workholding.
The other style, which is what came with my machine, uses a key
akin to that for a Jacobs drill chuck, with the gearing engaging a set
of gear teeth on the OD back of the scroll plate, exposed to the outside
of the chuck. This style happens to have reversible jaws. Crank them
all the way out, and look at the teeth in the backs of the jaws to
enaged the scroll plate. In normal chuck jaws, they look like this
from the bottom:

while in this style of chuck, they look like this:

allowing the scroll plate to drive them either way around. Note that the
jaws have to be inserted in reverse order (3, 2, 1) when reversed to
center well.
I have never seen just the jaws on eBay (and if I did, I would
snatch up a set for my second (and more worn chuck) of the first style).
But I *have* seen auctions for the entire chuck of the first
style, with two sets of jaws (normal and reverse) *plus* a set of unused
soft jaws. The first of these auctions, I bid on and won the complete
chuck. I have since seen a couple of others brought to auction. Note
that these are *not* cheap. :-(
I have also seen a set of soft jaws sold separately. You could
get such a set, and bore them to make the reverse jaws you are looking
for -- even though they are not hardened, they could serve well.
Finally -- could you *please* turn off the HTML in your
postings? I have modified the HTML from your posting below so it will
not be recognized as HTML by your newsreader, and so you will see what
the rest of us (who prefer to use non-HTML-capable newsreaders for the
greater security the offer) see every time you post.
My changes were:
1) Replace every '>' with '}' (except those added by the quoting
process.
2) Replace every '<' with '{'
3) Replace every '&' with '~', so that simple spaces are not turned
into "& nbsp ;" (without the spaces), causing a single
character to occupy six spaces.
HTML is good -- in web pages where it belongs. Usenet news was
*not* designed to use HTML, and as a result it wastes space, and looks
ugly.
Thank you,
DoN.
