The feed-screws on these models were changed to a left-hand thread, so allowing a “normal” feel – where turning the screw to the right resulted in a deeper cut; a far better arrangement than the “cack-handed” originals that did the opposite.
The 3-jaw chuck and the drill chuck delivered with this lathe were identical to the ones supplied earlier, with the ring-scroll portion of the 3-jaw the part gripped to turn the scroll being diamond knurled and drilled with 6 Tommy-bar holes.
Factory 3 Jaw Chuck: However, by the mid s the technical literature with USA-market machines was showing two motors: Emvo order no doubt to give the unit a “machine-tool” or “technical” appearance it was finished, apart from the black-varnished field-lamination area, in an attractive crackle-black paint to match the lathe. The Instruction Book for the Mk.
It includes options for more power, table saw and router table. A umimat, screwed in through the left-hand face of the casting, engaged against the cone, and drew the headstock down and locked it in place. The “Light” models were painted a hammer-effect green and with minor mechanical alterations only, including rather crude, cast-in degree-graduation marks on the front of the headstock. Late s carriage with a single locking screw on the cross slide, wasp-tail handles and crude, cast-in degree marking on the feed-screw handwheels.

I take very good care of my tools. This example also has a locking ejco on the cross slide. The machines enable the user to have a drill presslathe and milling machine.
See each listing for international shipping options and costs. Colours, as ever, pose a problem and instead of a single, standard finish, examples have been found in crackle-black, a light plain flat grey and others in either silver-blue or silver grey – with the latter two in a “hammer-effect” paint. It must be emphasised that the manufacturer did not use these, nor were the alterations given any publicity at the time.
It is capable of working wood, plastic and soft metals i.
This is not a factory part. Although the system worked well enough, it did not have the clamping power of the later type and would probably not have stood up well to the demands of heavier milling cuts.
The entire body of the drill chuck was also given a distinctive and effective diamond-knurl finish. That section of the base on which the headstock fitted was rectangular in shape, with a flat front, and bored to accept a large “inverted-cone” that allowed the headstock to be rotated or quickly detached.
This will assure proper bearing preload and achieve the best bearing life. Number of bids and bid amounts may be slightly out of date. Unique to the first one or two years of production the base’s other main identifying features were its middle section, formed into a convex chip tray with a flattish bottomraised ridges running along the front and back walls and the boring of the casting at both ends to accept two solid-steel, mm diameter bed bars each retained by a horizontal grub-screw.
Motors used on this model included the Dutch-made painted type the large “round” versionan early example of the very much stronger and reliable U90 but with more sculptured end caps as shown in the large picture in the brochure and the “regular” U90 in a colour to match the lathe. Free shipping to the lower 48 states. The E collets have just 6 slots and, as with a collapse range of only a few thousandths of an inch, are intended for use only with the “nominal” size marked on the collet.
Because it’s possible to convert a “W” to the specification of an ordinary metal-turning Unimat or use the “W” headstock on another machine it’s likely that the model may appear on the used market in a variety on non-factory specifications. Some versions of this lathe have been found with two locking screws on the cross slide, one in the normal position nearer the front and the other in line with it further back.
Some examples of this version have also been found with saddle and cross-slide locking screws the latter with a small brass plug pushed against the right-hand cross-slide bar but such fittings appear not to have emxo standard until at eco the Mk.
Notable for the introduction of a rounded “step” in front of the headstock through which a simple vertical alignment pin could pass, this was the last version of the Unimat to use a cast-iron base.
There were several serious oversights on this first model including a lack of provision to lock either the saddle or ls cross slide to their respective bars and feed-screws with a ‘right-hand” thread’ – giving that annoyingly counterintuitive situation where turning a handle to the right produced a moment towards, instead of away from, the operator.
Upon first assembly the base casting and headstock were jigged and a small vertical slot cut across the junction of their front nuimat. The plain bearings were lubricated through wicks, and it’s important not to take these out and squirt oil in directly – doing so will wreck the motor.
Manufactured in fully-machined cast aluminium they had deep ‘V’ grooves and were mounted in the reverse direction and with the pair used on the motor and idler stud at mmlarger in diameter. This had a big, round-shaped induction motor with matching wrapper paint, a small red name plate mounted unimaat down on the jnimat face of the headstock, green paint and die-cast hand wheels with the wasp-tail handles.
This article has multiple issues. By reversing the pulleys, and rearranging the belt runs, 11 speeds of approximately to r.
The ball races are grease lubricated – using oil will wash the grease out and foul up the inside of the motor, again promoting failure. Because of its construction, and the fact that the bed bars unimatt socketed into the base casting, it was necessary to dismantle the entire lathe if the tailstock had to be removed.
