Compound Slide Rest fitted with the Combination Tool Post. Note the T-slot machined into the full length of the cross slide - this was to mount front and rear screw-adjustable stops (the abutment can be see between the gib-strip adjustment screws). A feature unique to Stark was the mounting of the ring carrying the micrometer-dial zero mark on two rods attached to the inner casting - they can just seen (on both cross and top slide) in the pictures above and below.

Plain Tool Post:
The Stark toolpost was carefully designed so that the stud which bore against the tool to clamp it down was not part of the tightening screw. The rocker and other parts were pinned in place - a thoughtful touch to help keep things in place and reduce the amount of time spent looking for misplaced components.
Four different models were available to fit the range of lathes:
CLEFT fitted the No. 2  (3/16" tools)
CLERK the No. 3 & 31/2  (5/16" tools)
CLEVE the No. 4 & 41/2  (3/8" tools)
CLICK the No. 5  (1/2" tools).

Combination Tool Post:
This was a well-made unit with provision for holding round as well as square and rectangular-section tools. The round-tool holding collet was fixed into an eccentric bush to provide a small range of vertical adjustment.
Four different models were made: the smallest code named CLIFF was for the tiny No.2 lathe and accepted tools up to 1/4" square and 5/16" round. The next version, for the No.3 and 31/2 lathes, had the same capacity and was given the accessory code CLING. Somewhat larger was that for the No. 4 and 41/2 lathes which took 3/8" round and 5/16" square tools and was listed as the CLIPP. The largest, which weighed a substantial 4 lbs and took 3/8" round and 1/2" square tools, was code-named CLOAK and fitted the large No. 5 lathe.

Ball-turning
Tool Slide. Designed for the easy manufacture of spheres up to 4" in diameter.

Screw Slotting Attachment for use on lathes with a 7" to 9" swing.
This device was intended for production purposes where quantities of small screws need to be slotted.
The screws were held between two jaws which, being mounted on a swivel base, could be swung away for loading and unloading. An adjustable stop controlled the depth of cut.

Boring Tool Rest:
another production accessory designed to assist in the manufacture of parts which required repetitive boring, recessing or facing operations. The tool was held in an eccentric quill which took round tools up to 5/16" diameter. All slide movements were operated by levers controlled with adjustable stops.
