Indeed so, in fact the Record has a corrugated shaft, and comes with a
cast collar which has matching corrugations on its inner face. Rather
than being screwed to the bench top, it needs to be bolted through, the
bolts going via a backing ring. Once engaged, this enables a *huge*
pressure to be exerted. Did i say *huge* ? I meant HUGE.

I have a couple of collars in the top of my 'old' bench, and a couple of
spares, one of which I always intended to go horizontally into the right
hand bench leg (the face vice is on the left)

In use, they are fiddly to set up, and tend to have little finesse
between slack and timber crushing.

But just the job for initial roughing down, or for work on green timber
or similar.

148495 paul womack <pwomack@p...> 2005‑08‑09 holdfast size?
I recently found a screw operated (modern, technical
version of a forged holdfast :-) at a fair price.

I thought it was anonymous, but during rust removal,
I discovered a shallow stamp that indicated
William Marples (Hibernia) and the usual
Shamrock.

What surprises me is the scale and weight of the
thing:

http://www.wdynamic.com/galoots/4images/details.php?image_id=1969

It weighs 2650 gm (5lbs, 13 oz) and the shaft
is 25mm (let's face it, it's an inch).

Are they usually this robust?

I have an old one which is about that size.  I don't think it is marked
but can check and report back if it is.  It has a smooth shaft like the
one in your picture.

Further research in the tool pile
reveals the following:

Record #146 screw-holdfast

1634 grams, 15/16" shaft diameter, 10" shaft length

Woden X110/B75 screw holdfast
1086 grams, 3/4" shaft diameter, 9" shaft length.

So the oldie's a biggy.

I'll head for the catalogues if I remember.

My unmarked example has: 11" shaft length, 7/8" shaft diameter and the
arm reaches 7.5" from the shaft.  Here it is in beautiful primer red:

A cleanup may reveal a maker's mark but it doesn't look promising.

Some rummaging in the book pile gives

1935, Buck & Hickman
pillar length x diam
10 x 3/4
12 x 7/8
14 x 1
16 x 1 1/8
18 x 1 1/4

1935, Buck & Hickman

Woden (not shown in catalogue, but I recog nise the model #)
Labelled as reach, opening, diameter of hole for collar
X110,   5 7/8,   6 7/8,    1 1/2
X111,   7 1/16,  7 5/8,    1 3/4
X112,   8 5/8,   9,        2

 From a previous post, my X110 has a 3/4 shaft.
Those collars are a good deal bigger OD than ID.

Sounds like my big 'un is a littl'un by
old standards! Mine is the 14 x 1...
