Cutting and grinding gears for a 1904 touring car – and having a shot at repairs for a rifle manufacturer
Because of our reputation for producing high quality work, we are cutting and grinding two sets of gears for vintage cars which are being restored.
One of them is a 1904 Winton touring car, similar to the model pictured, with a two-speed gear box.
In 1903, a Winton was the first car to travel across America. Starting in San Francisco and finishing in Manhattan, the journey took just over 63 days!
All of the gears have been reverse engineered from samples supplied and will be quieter than the originals because they will be hardened and ground.
Elsewhere in our workshop, a local manufacturer who has been making shovels since 1740, has used Kenward to regrind some tool holders and repair a spindle. Both were required rapidly and we obliged. The company has since sent us a shaft to manufacture and its housing to rebore and rebush.
The customer – recommended to us by one of our sub contractors – is delighted with our work and has said that we will be their preferred supplier for any more breakdown work.
A West Yorkshire-based precision rifle maker has used us to machine a new part for one of his machines. The job was urgent as the machine was required for a lucrative order to go the USA. This is the third time this customer has used us since the middle of 2019.
A large local recycling plant and incinerator suffered a shut down when a peg on a key machine snapped off. Working into the night, we manufactured a replacement and got the plant running again within six hours.
We also continue to develop our core business of manufacturing gears, shafts and pinions for industrial and military applications and we are seeing an upsurge in orders from existing and new customers.
The recent commitment to invest in CNC machining centres with live tooling and a five-axis milling machine will enable the business to manufacture certain products more efficiently, increase our production capacity and give us the capability to machine larger components.
Kenward Precision is delighted to have been invited to manufacture a new set of gears for a 1912 Hispano Suiza Alfonso car which is undergoing restoration.
The gears will be reverse engineered from the originals supplied, (right), but the new ones will be finely ground to ensure that they operate as quietly as possible.
The work will involve turning the blanks, slotting some, spark eroding some, cutting the gears, case hardening and final grinding.
This car was named after King Alfonso XIII of Spain who liked it so much that, at one point, he had 30!
Our apprentice Liam Medley is coming along well in learning the skills of worm shaft and worm wheel machining. He is developing into a key member of our team of highly skilled engineers.
We are in the process of manufacturing more gears for naval radar equipment which requires extremely precise gear cutting, heat treatment and final grinding.
Meanwhile lot of thread grinding of stems for sub sea oil and gas equipment is going through the workshop at the moment.
The stems are manufactured from various specialist alloys, such as Inconel, which requires extremely precise set up and grinding to ensure that they operate correctly in arduous conditions.
Many of the stems also require phosphor bronze nuts to move up and down the stems. These also require extremely precise machining.
More grinding of metal sprayed rotors is being done to support the repair work of motors undertaken by our sister company, Westin Drives. These are quite often required to be delivered to extremely tight deadlines.
Our machines have been particularly well employed in the past month, in response to a large and varied order book.
Among the jobs completed was the thread grinding of stems made from Inconel, a nickel-chromium based super-alloy mainly used in extreme operating conditions.
Grinding this material calls for a high degree of skill by our engineers. We also manufacture nut to fit the stems after they have been ground.
Elsewhere in the workshop, we manufactured three urgently required components for a large local engineering business which had suffered equipment breakdowns.
Urgency was also a requirement of a new customer who wanted a shaft splining to fit into a gear box. We succeeded in meeting the five-day turnaround deadline for this work.
Meanwhile, we have supplied special precision pinions and gears for a new naval radar system. The work required precision turning, gear cutting, splining and surface and bore grinding.
Our team of engineers are completing a large spares order for Europe’s largest supplier of boiler cleaning equipment.
The work, mainly of pinion shafts and helical gears, has taken several weeks and has included many of the processes we offer – turning, gear cutting, gear grinding, splining, surface grinding and bore grinding.
Meanwhile a large chemical processing plant that uses Kenward as a preferred supplier for engineering repairs has sent in large, complex valve which requires machining to a high tolerance.
Locating the valve on the grinding machine proved a challenge but we are now ready to start the machining process and return it within the tight schedule required by the customer.
Elsewhere in the workshop, we have completed the machining of a large set of nylon gears for a manufacturer of liquid filling machines. The customer uses Kenward regularly for the machining of gears from several different materials.
We are pleased that a recently reformed manufacturer of textile finishing machines is using us as its principal supplier of precision engineered components. These include special screws and fixings, small and large shafts and special blocks and brackets.
Finally, few precision engineering businesses will machine cast iron bar due to the potential for the swarf contaminating the lubricants. We simply change the lubricant when the job is finished.
We are happy to machine cast iron and we get fairly regular work of this type.
Metal spraying and grinding capabilities are being used to good effect at Kenward Precision Engineering.
Several customers, including leading gear box suppliers, are sending us shafts to be metal sprayed and ground back to size.
We also offer the same service, but with chrome applied to the component, then ground back to size. Several customers use this service, including industrial valve suppliers and gearing specialists.
Our engineers have just received an interesting challenge prompted by a client's machine breakdown: an order for the supply of two new worm and wheel sets which must be delivered within eight working days.
Although this is an extremely tight deadline, we are confident that the delivery will be made on time.
We were recently approached by a large international valve manufacturer to undertake some urgently required final grinding work.
Our skilled team of engineers completed the job ahead of the customer’s expectations. As a result of that, plus the quality of the work, we have been promised more business.
Kenward Precision Engineering is renowned for the quality of its final grinding, so please get in touch to see how we can help with your grinding needs.
A major manufacturer of crop protection products contacted us one Friday afternoon.
Could we manufacture a new internal flange for one of their processing lines for delivery the following Monday?
Working over the weekend, our experienced engineers managed to reverse engineer the flange which was delivered to the customer first thing on the Monday morning.
Our customer was absolutely delighted with the speed of the service and quality of the work.
If you require our engineers to reverse engineer a component for you, please give us a call. It is one of our specialities.
A local specialist engineering business required 10 sets of bevel gears to be cut for an urgent repair job.
Our engineers had to set up two specialist bevel gear-cutting machines to the precise measurements and ratios required and run them constantly for 12 days to achieve the delivery date.
As a result, we have been awarded more work of this type by the customer.
We have been commissioned to reverse engineer a selector gear for a 1914 Humber motorcycle for a local enthusiast who regularly takes it to rallies during the summer.
The work will involve turning, gear cutting, heat treatment and final grinding.
Humber Ltd was a pioneering manufacturer which produced the first practical motorcycle in Britain by fitting one of its bicycles with an E J Pennington two-horsepower motor in 1896.
The company's early motorcycles were built under licence by Phelon & Moore with a single-cylinder P&M engine and two-speed chain-drive transmission.
This licence was terminated in 1905, so later models had Humber 496 cc, 596 cc and 746 cc engines.
Meanwhile, Kenward Precision has been awarded gear cutting and gear grinding work by a leading Yorkshire-based gear box specialist.
The business was won because of our ability to meet deadlines and to produce high quality work.
