Default Toolholder unseating in the Dickson style toolpost - update

[...]


Just done that and all 8 T pieces seem to be flat and the holders
undamaged in the clamping area. One T piece closest to the chuck has
obviously met it on occasion as it has some evidence of an arc worn
slightly into the surface but otherwise OK. The T piece I crashed is
flat even though that incident broke a small part off the flange at the
top of the eccentric pin. The spare parts included 2 T pieces, both
flat, one complete eccentric shaft, and the bit of eccentric shaft that
fits in the T piece, both ends having been broken off.


In the holders I have, none has the spool-shaped adjuster nut. I would
assume that they were removed, but I don't know why.


I think this has been mentioned before but not much point in having a
quick change tool holder with those nuts missing as you can't just throw
it into place and have the height correct.


Shame you're in the US and the holders are in a state from what you said
before. The Dickson holders always seems to fetch good money in the UK
on ebay. Luckily having had the Toolmex version and then bought the
Harrison with a Dickson and holders I now have 5 which will take 22mm
height tool and a couple of ones to take round or square to about 17mm.
I haven't found a use for the Morse taper holder yet. That allows me to
keep the commonly used tools set-up with a couple over to set-up with
other tools as required.


I'm also suspicious that the Dickson toolpost I have is too small for
the Clausing 5914 lathe.


I have looked at www.lathes.co.uk which is normally a good source of
info on lathes but it doesn't seem to mention the Clausing 5914, maybe
some rare variant of a more common Clausing. Any way another search
showed the 5914 to be a 12" lathe and I have a Kerry 11" and the M300 is
13", both are fitted with a Dickson toolpost and holder width of 73mm (2
7/8") and the height is 63mm (2.5") and that seems appropriate and was
given as suitable when I bought the Toolmex for the Kerry. Dickson do a
smaler size IIRC so maybe that is what you have.


Anyway good luck on your choice of a new toolpost and let us know how it
goes.


Thanks. It should arrive this week, although I will be away from my
shop this weekend.

Ahh mental anguish until you get home to play again.
