hi all , its been an age since ive posted, but im back for advice! is
anyone familliar with the 4 postion toolpost these use, not the quick
change type! mine doesn't index, and has a nut on the top which needs
nipping up. the correct handle is on, the internal parts are there,
theres 2 indent plungers one is free but the one that is connected to
the toolpost base doesn't move. is this wrong? i cant find a parts
drawing for this on the web and have never took one to bits.... also,
the t nut that tightens the toolpost clamped, should it be a tight fit
in the slot, or would one with an 1/8 of an inch of play be acceptable
heres me hoping for some guidance!
thanks paul!, i'll give them a ring, but ive been meddling this aft, and
to have sorted the indexing out!! but now ive a more simple
question :D how
does the toolpost lock down ? mine has a hex nut that i
need to loosen and nip
up with a spanner, now 25 odd years back as an
apprentice i remember using a
student an am sure the top part of the
post had a half nound nut on top, also i
notice a verticle hole running
verticaly, parallel with the locking stud, could
a pin hold this in
place so when the locking lever is used to unlock and index
round the locking nut is loosened?
oh and it looks like the t nut has been made(wrongly) as to allow the
to work ive (mis)used an old slip block as a shim..... for now
oh dear, neither the 1800 or the old online student manual show my
after speaking to the service bloke at colchester, i believe
topslide(compound) is the type for the american market, and am
wondering now if
its an after market one,at least one from another
lathe.... so the next question
is to do with the underside of the
toolpost! mine has a grid machined on the
bottom and the threaded tube
that runs from the bottom to top also is machined
the same. has anyone
seen this on a student before?
there was a bloke in my town(york) who had an old student at home but
last year so that avenue is closed to me now unfortunatly, i
posted a similar
question on the colchester user forum (yahoo groups)
but have had no answers
i'll fettle it tho!
I still have the 4-way block from my MkII student, that just has four
indexing holes in the bottom.
I really can't remember how the rest of it was arranged, I modified in
in an irreversible manner to accept a Dickson post.
If anyone can make good use of the block itself, it's available for
