More unknown attachments – Myford / Warco

[CJSParticipant @cjs]

Hi all,

Earlier this year I got myself a Myford Super 7, Warco A1S mill, and a good selection of tooling and material from a workshop clearance. The mill is in fairly good condition and I got it up and running with the VFD without too much trouble. The lathe was not fitted with a motor, but a few motors were included in the lot, one of which I managed to fit and get running. It's not quite as pretty and has a little wear, but certainly fine for my use. I need to improve the motor mount as it slips a little.

I finished my first starter project of a machinists hammer. Quite happy with the result, a lot of learning along the way.

I've been able to work out what most of the tools and accessories are, but I was hoping someone might be able to help me identify some of the below parts:

1)

The top part is a myford spindle/chuck mounting plate. These bottom parts look like some type of chuck plate, but the 3/6 bolt pattern doesn't align with the myford mounting plate. The centre hole does not go all the way through. The body appears to be stainless (not very magnetic at least, and very heavy), and I believe the black part may be carbon as it turns to dust when scratched with a knife, and is electrically conductive. I have one more which is threaded in the centre to fit the myford spindle. Quite odd. The larger part is stamped with either an "AK" in a circle cocked sideways, or possibly a logo with the side-profile of an eye. Two "3"'s which have been crossed through, "1.4571", and "43792". The smaller part is stamped "CG" in an oval and "93493" or "93483".

2)

This appears to be a 2 axis positioning plate. The brass knurled nut jacks the centre part up on a thread. The centre part can also freely rotate within the 3x radial slots, constrained between the two adjustable stops on the left. Seems like it wouldn't have the strength/rigidity to stand up to milling/turning operations, so maybe it's unrelated. The previous owner was in to making parts for fishing and to test fishing line.

3)

I've only put these cast parts together based on their matching colour. The T slot on the right angle fixture does not seem to fit the bed of either the Myford Super 7 or Warco. No markings.

4)

I suspect these parts are Myford, as the paint matches some other accessories perfectly. The numbering convention of the top part is also similar to another myford casting, but I can't find anything online relating to these numbers. 72/1939/1 and DBL 227/1 or 226/1

Interested to hear if anyone recognises anything!

Thanks,

Chris

The first part is a faceplate. Myford made them in two sizes. So look for 'lathe faceplate' to see how they are used.

The two parts are likely industrial surplus that the previous owner has acquired from somewhere and was in the process of repurposing into backplates. The numbers stamped into them relate to their previous life. 1.4571 is indeed a stainless steel grade. Type the other numbers into Google and see if anything comes up.

The second part seems to me to be upside down as pictured. I think it is something like a positioning stage for a microscope. You can move it in X, Y and Z and rotate it under fine control (the aluminium bit and the screw on the left).

Photo 3 home made angle plate. The right hand part looks to be upside down. The three feet give planar contact with, for instance, a surface plate. Maybe a height gauge bolted to the top in a previous application.

Phot 4, lower may be Myford small angle plate – used on the faceplate above and the vertical slide. Other part, no idea.

72/1939/1 looks like the base for the Myford saw table attachment.

The discs with carbon inserts look like part of a labyrinth seal. A mating face with multiple concentric rings would mate with it. From a comressor, vacuum pump or turbine.

[Nigel Graham 2Participant @nigelgraham2]

The tools behind it suggest the 2-axis device is quite small, but too large for use with a conventional microscope. Possibly a special type used for tool-room metrology, though.

Or it was a special jig for repetition manufacture of a small component for something unknown. Like the unidentifiable discs, it might have been something the previous owner had himself acquired lest they come in useful!

The numbers on the discs could be almost anything: steel grades possibly, but part-numbers very likely.

Agreed!

Re your two axis gizmo.

I have a very similar column section, without the two stages; mine came attached to a magnetic base, so I've made a column to fit the centre hole and use it as a fine adjuster for a dial gauge.

The one I have is signwritten "Ealing" on the top of the black arm, which would fit with it being a 4 axis microscopy stage of come sort.
X & Y with the dovetail slides, Z with the knurled nut and also able to rotate.

It's not in the current Ealing Catalogue, but it might point you in the correct direction.

The two axis device has been cobbled together from old style standard optics laboratory hardware.

The vertical motion device is made to carry a post with a tapped hole at one end and a short thread at the other onto which a variety of lens holders, filter carriers, small optical devices et al could be screwed. The evrtical movement was needed to carefully set everything to a common centre height. Regrettably the pin in slot fit was never exceptionally good so adjusting the height usually twisted things a fraction which could be frustrating until you learned the trick. That one looks to be Beck, Ealing-Back, early Ealing or PTI (Precision Tool & Instrument Company).

The twist device may be shop made, PTI or from one of the short lived lab accessory parts makers around in the 1950's and 60's. The twin screw bases are again probably from a small maker. There is a certain PTI air about them but the quality looks off. Ealing-Beck and Ealing versions are distinctive castings vertical screws holding a trapezoidal gib on one size.

Thanks for the helpful responses!

Baz is spot on, 72/1939/1 is indeed a part for the table saw attachment! I haven't come across any of the other parts.

DC31k also looks to be right about the "Myford small angle plate".

The two axis table being from an optical application seems believable. Thanks for the hints.

Two more parts have left me scratching my head today:

5)

The rounded/knurled nut at the back can be pulled to retract the flat bladed end and rotated so the little bayonet style pegs before the nut sit in/out of their groove at different depths. Can slide along the bar and be set at different angles. What it's used for? No idea!

6)

Obviously an indicator holder or similar at the back, but also has a tiny V block mounted on a tailstock style mechanism?

5) is the indexing pin/plunger for a change wheel dividing or indexing device. See, for example:

https://swarfer.co.za/lathe/divide.php

Maybe 6 was used to check something for roundness or diameter (zero the indicator on something of the correct diameter, slide the candidate part in and see what it reads). With it properly set and clamped, you do not have to mess around moving it side to side to find the maximum reading.

There is a video on Youtube of the Colchester Lathe Company. I think it shows them checked bearing rollers fresh off the grinder and sorting them into different boxes depending on size, so that anything that went into a particular bearing was very closely matched.
