Following the latest UK Government announcements, non-essential businesses (doesn't that sound cruel...) are now examining their positions and responsibilities. We are truly fortunate at Hemingway in that our workforce is a very close team, isolating here together - 24/7. However... parts of our supplychain are groaning.
Accordingly, although we will gratefully continue to accept your online orders, we will NOT automatically take your payment, unless we believe we can get your parcel away in a timely manner. Our hope here is to reduce stress and uncertainty (your's and our's) by not holding your money whilst we battle any stock and carrier issues.
PLEASE continue to send orders using the "Confirm" option now shown at the checkout. We'll then contact you directly with our current stock and carrier position. All being well, we'll then take your payment (over the phone or with an online payment link) and get your kits away pronto. Alternatively, we'll register your interest and contact you again when conditions improve.
Whilst this is admin-intensive for us all, it seems to be working well. We have only a handful of "Confirmations" not yet converted into payments and shipments. In due course, we will return to normality.
Stay strong and safe - these are the times that try men's souls! ___________________________________________________________________________
A Call to Arms
Like many millions billions, you may now be locked-down and anxious?
With the TV spouting either doom or repeats and social merriment on hold - count yourself blessed that you have already set up that special isolation room - the Workshop!
Whilst nothing short of a Hemingway Ventilator Kit (sorry, not coming...) would be especially relevant, the act of achieving conquers fretting every time. What if, by the time that "All Clear" sounds, you'd become an Olympic machinist with extra workshop assets and a deep love for Engineering? Now that would be time well spent.
The UK currency is as weak as a weak thing (March 27th: £1.00 = $1.24 = €1.12 = AUD2.02) offering a deluxe silver-lining to our fine customers in the Colonies, on the Continent and down under in the Antipodes. Strike now chaps!
Incidentally, the US National Institutes of Health (N van Doremalen et al) report that the virus can remain stable on steels and plastics for up to 3 days and cardboard for up to 24 hours. Even if we had succumbed, only our very luckiest customers receive their Hemingway order in 3 days so the kit itself would not increase your exposure. If you can curb your excitement however, it may be sensible to leave the courier-handled, cardboard parcel untouched for a day?
We'd guess that the Quorn Universal Tool & Cutter Grinder is known by just about everyone who owns a small workshop. If you haven't built one - "odds on" you've thought about it?
Launched by Prof. Dennis Chaddock and Model Engineering Services in 1974, the Quorn is a triumph of engineering design and a hugely desirable asset.
Now... what if we were to tell you that:
• Following an agreement with Ivan Law at MES, Hemingway are proud to have become the sole authorised supplier of the Quorn. • The new Quorn Mk3 design has been released, offering customers a much quicker build and easier, more accurate set-ups. • Full material kits are now available. Not just castings but everything required to complete your Quorn Mk3.
Ivan Law's beautifully designed Fixed Steady is now available with the addition of finely adjustable fingers, allowing a stable centre position to be quickly established and securely locked.
From Ø1/4" to a massive Ø5" [Ø6mm-Ø127mm], you'll not be stuck for capacity on longer jobs!
3 versions are now available to suit:
• Myford 7 Series (Super 7, ML7) • South Bend/Boxford (9" & 10") • Myford 254 & 254 Plus
Recently completed by Michael Stratton (UK) this Seal Major has been built to a very high standard. Michael has also included a vertical distributor, water pump and radiator to his own design. Watch the unsilenced engine later in the video - a lovely crisp crackle!
This engine is a 30cc version of Westbury's "Seal". Designed in 1950, the Seal Major has been used in both 4ft - 6ft boats and 5" scale locomotives for the past 66 years. It presents the constructor with a challenging yet "do-able" project - you'll find plenty to learn along the way and huge satisfaction when it finally fires!
While the ordinary hacksaw is an indispensible hand tool for all metal workers, the manual labour involved in operating it is tedious when a great deal of cutting has to be done on large metal sections.
To earn its keep however, a powered hacksaw must be man-enough for the job but also small enough to avoid dominating the workshop. Westbury devoted a great deal of thought and experimentation to this design which is surely the world's most compact. The machine is just 7½" wide, 9¼" tall and sits on any bench deeper than 17". It's about the same size, and just as portable as, a standard toolbox!
This great machine will quietly slice 2" thick steel whilst you get on with something more interesting. An adjustable weight and hydraulic damper regulate the cutting load and the machine knocks off once the job is done. The vice jaws swivel for mitres or for gripping tapered stock and a length stop is provided for accurate repeat cuts.
The machine cuts at 90 strokes per minute using standard 10" blades and the stroke is adjustable between 2" to 3½". Metal is cut on the backstroke and the connection of the frame to the driving crank is arranged to produce a downward thrust on this stroke and to relieve the load on the saw as it returns. The heart of the machine is a 15:1 worm/wheel gearbox which is supplied complete and ready to fit. The 90W x 240V motor supplied with the kit is suitable for both 50hz & 60hz supply and provides 20% more torque than Westbury envisaged.
Apart from a plug, the kit contains ALL necessary material. In all, there are 21 cast components of aluminium, iron and gunmetal. Barstock, fasteners, electrical components, drawings and construction notes are there too, along with an Eclipse Plus 30 ALL HARD blade to kick you off. Incidentally, the base casting (15" x 7½") arrives pleasingly flat so, unless you feel compelled, it will not require flycutting.
Now perfectly engraved scales can be produced time-after-time, with none of the "variations" that haunt the amateur's work! A slender, dovetailed ram slides solidly and accurately under the complete control of the operator. A rotating turret carries 3 fully adjustable stops, allowing lines for units, fives and tens to be struck. The cutting tool and turret can be set at either end of the ram allowing both cylindrical and flat work to be completed at any angle. The complete fixture is held in the tool post and can be set-up in the same time as any cutting tool.
This classic tool is as satisfying to manufacture as it is to use! Radford's unique design was a sensation when it appeared in 1970. The original design however required constructors to cut their own rack directly onto the back of the ram and a pinion directly onto the spindle. With Riley's update, the rack and pinion are provided as finished items so that no gear cutting is required. Along with drawings and construction notes, the kit arrives complete with all necessary bar material, fasteners, springs, HSS tool together with the rack and pinion blanks.
Rotary Broaching, although in use for over 100 years, is a rare sight in the small workshop. And yet, "drilling" square and hexagonal holes in virtually any material has never been so easy! The Compact Rotary Broach can be held in lathe's tailstock or the miller's chuck and will effortlessly transform a pilot hole into an accurately cut hex, square or spline up to a major diameter of 8mm (5/16") and a depth of 7mm (1/4").
This allows infinite possibilities for the production of custom fasteners, miniature sockets, clock and valve keys, carb jets, tapping collets, double keyways, etc..
Compared with end-milling, flycutting is often sited as the slower and therefore inferior process for milling flat surfaces. Whilst this opinion may hold water for industrial scale work where large volumes of material must be removed at the minimum cost, for finishing cuts in the smaller workshop, flycutting is by far the better bet.
Unlike expensive end mills, your flycutter will last indefinitely. A dulled cutter can be brought back to perfection on the bench grinder by sharpening just one face. The cutting diameter can be adjusted to any surface up to 7" wide, allowing a finishing cut to be made in just one pass. Provided the head of your miller is square to the table, the resultant surface is both uniform and flat. With a light cut and a slow and consistent feed, the finish obtained on steel, iron and non-ferrous materials can easily resemble surface grinding!
The design is very sturdy and the body includes and integral parallel arbor to be gripped with a collet in the miller or lathe. The kit arrives with all necessary materials together with a square 1/4" HSS toolbit. The arm, produced from 3/4" square bar, is a particularly interesting and satisfying component to make!
Situated in the centre of Britain's cotton and coal industries, Benjamin Hick grew his Bolton foundry business to employ over 400 men before his death in 1842. His son John then partnered with William Hargreaves in 1845 to form Hick, Hargreaves & Co, supplying a vast range of stationary and locomotive steam engines, boilers, water wheels and mill gearing to customers at home and overseas (including India, Russia, Spain, South America, China, and Japan). In 1864, they were also responsible for the introduction of the highly efficient American Corliss valve gear into the UK.
This particular 10nhp engine was shown by the company at the Great Exhibition in 1851, alongside their diminutive 2nhp Oscillating Engine. Geoffrey King, a professional Engineer and member of the Newcomen Society, detailed this 1" to 1' replica in 1956 from the original Hick drawing set. The vertical layout made this engine particularly suitable for driving "manufactory" line shafting, with the cylinder, valve chest and feed pump installed in a pit below. Where more that 10nhp was required, gangs of engines could be coupled together and managed by a single boiler and "engineer".
Complete with its 7" x 8½" plinth the model stands almost 14" tall propelling a 7½" flywheel. With a bore x stroke of ¾" x 1 7/8", the engine has a double acting slide valve, an eccentric driven feed pump and a Watts type governor, driven directly from the crank with bevel gears. An imposing runner, the 'Crank Overhead' shows a great deal of movement when underway.

Instrument Maker's Vice
As in so many fields of human endeavour, suitable tools are a prerequisite to progress. Once the sideline of cutlers, instrument making has a long and distinguished history, with elite craftsmen working hand-in-hand with surgeons, chemists, physicists, astronomers and industrialist of every flavour to develop the equipment necessary to analyse results then exploit new scientific findings.
Within the instrument maker's workshop, highly prized manual skills are developed over many, many years. Filing, sawing, lapping, chasing, honing, scraping and polishing small parts to within infinitesimal tolerances to create world-changing devices.
This versatile vice provides movement in virtually all planes, allowing a workpiece to be firmly gripped then locked in exactly the right attitude for further finishing. The 1½" wide jaws open to 1" to accept flat or cylindrical work. The vice's iron base is cast with an integral 4" long tenon so that it can be securely held in a larger bench vice. The kit arrives with all necessary material, drawings and construction notes for this hugely useful platform. Click the image for a closer look.
