I've got the cam going today, I'll be casting.
steady rest, follow rest, carriage lock, and
a test of a leaf pattern to go onto a small bowl
this is a test for a new designs I'm working on.
I'll be making molds this moring plan on firing
up the furnace about 3:00 pm cst ( gmt-6 )

I am posting a copy of a reply I received from Mick Collins, the
owner of one of these machines and the link to the picture I had
previously posted. Hopefuly we canget him and the others he mentioned
to join in our little project.

Hello DuWayne
                 Very pleased to hear of your interest and e-group.
You
are very welcome to add a link to my site. I only wish I could help
with
some info' re castings or patterns but I've been trying for some years
to locate either but without much luck.  Re drawings, I do have a
complete set, approx 80 sheets, hand drawn on A4 size paper by
David.  I
do know that he sold several sets and Mrs Urwick, now a very elderly
lady, still owns the copyright, She will be thrilled to hear of this
group and I'll write to her to see how she feels about the drawings
appearing on the net!

   I do know of one chap on your side of the pond with a complete set
of
castings and of another would-be builder in N.Z. and will forward your
invitation to both of them

   Meanwhile I'll be happy to answer any questions re operation and
performance of the machine.

Recently I saw an article in an old Pop Mechanics about a Hamilton 3-in-1 type machine - kinda looked like a watchmaker's roundbed lathe on steriods.  Apparently it never went anywhere commercially (maybe it wasn't any good?)

Thanks to JWE and the last article he posted I could create a better
drawing of the machine.  I scaled the drawing and maped it on some
quad rule paper to a scale of 1" per grid.  Only posted the front
view so far,  hope to get the other views done later this evening.

Some thoughts on an alternative way to achieve a Metalmaster type of machine
to test concepts or for someone who can not machine large castings.
There are lots of small horizontal bench mills with adjustable knees lying
around in the back of machinery dealers and scrap yards all over the
country.
I bought my Burke mill over 20 years ago after seeing it under some other
junk in his bone yard.
The Benchmaster also springs to mind as a possibility.
There were many others such as barker and Cincinnati mills.
I am attaching a picture of my Burke mill and one of a Benchmaster but these
are only two of many possibilities.
For instance some like the Barker do not use a knee but put the spindle on a
dovetail and provide a rise and fall lead screw for it.
This is another way to achieve adjustable center height.
Urwick achieved his concept by doing some very original thinking.
In the third article I posted to the files he mentions that with the
improved capabilities and technology when he was writing in 1982 there were
more possibilities at that time that when he originally designed it.
Now almost 20 years later think of the technology improvements available as
well as the old machine discards that that technology has obsoleted from the
commercial shop that we can take advantage of.

Would be great to have a regular picture of this machine in the files
section so if someone happens along and isn't sure what this is all
about.  Also for some of the non CAD users would be great if some of
the dimentions and drawings be in JPG so would have an idea how

Just spent some time with the specifications and drawings, and did
some estimates of the basic dimensions of the machine.  I uploaded a
quick drawing of the system with these dimensions.   All of these
look like they are within the  size range that would be capable of
being reproduced in the home shop.  Except for the bed casting most
parts look like they are fairly comparable  in size to parts made for
the gingery mill and lathe.

Hello All,

sounds like a great project and a cool little lathe. I got
a 'Rotozip' for Xmas and this looks like a good way to start making
some of the patterns. I will be adapting the 'Zip' to my CNC dremel
engraving machine which has fairly accurate X,Y,Z capabilities.
Although not a large enough platform for the larger parts. guess I
could make the longer parts in several pieces then index and fit
together for casting.  I'll be looking forward to seeing some of your
drawings and if anyone is experienced in converting to 'G' code might
need some help in getting started.

Saving files in ver 14 works good for me. I've gotten to
the point where I do all of my drawings in 3D this might
not be the best way to go, time consuming just for drawing
but you sure know what fits and what dosn't.

I'm not much up on lost foam, but unless you have a way of
injecting foam into a mold don't you have to remake the
pattern each time. Making wood patterns would be my choice
once you have them you can cast all you want. Making
cores is not hard using co2 set or air-set ( I've been using
an air set called alpha cure i think thats right the labels
off the can.)

I've also made molds and cores from a mix of 1/4 plaster
and 3/4 sand need vents though if using fine sand. A few
days drying time and then I usally bake them a while.


The air-set type have a lot of advantage you can use mutil
piece molds and glue them togehter.I've done sculpters with
up to a dozen pieces in the mold.

I have Acad 14 and 2000, so it doesn,t matter to me.  Some of the
compatible packages and the one freeware version I found only seem to
support up to the 14 version. Any sugestions on what version we want
to settle on ?
  I have been looking at some of the specs, and trying to scale parts

the gingery lathe and using a piece of 3/8 x 4 x 18  ground flatstock

I'm also on Acad, I'm using LT 2000, so I vote for any acad version, DXF if

Well just what I need another project but I've
had a lot of interested in this lathe since
I first ran across a pic of it a few months back.

A point I'd like to bring up is a drawing format.
Personaly I like autocad mostly because I've been using it for long
time now ( dos versions )up to the current autocad2000.

But DXF formats are not all alike every autocad ver.is a little
diffreent and some of the other cad prog's don't use the same
standered I ran into this writing dxf to g-code software.

Not trying to make rules just get it so we can share info

Hi Y'all
Welcome to the group, there was considerable interest in the message
I posted to the 7x10 group, so I started this one.  Hopefuly we can
get enough interest going to see the project done.  I have included
links to the information I could find on the web, and am looking
through a bunch of my old Model Engineer magazines to see what I can
find on this machine. I also e-mailed Mick Collins ( one of the
links) to ask his permission to keep the link and also to join the
group.  I will be posting notice of this group to the gingery-machine
group and maby we can get some participation from a few more people.
