TMMR Bearing Puller for SKF

Bearing pullers are difficult to adjust for different bearing sizes. TMMR can be automatically adjusted to different sizes. Invented by Warwick Evans for SKF Mapro as part of a range of bearing fitting and removal tools, condition monitoring instrumentation and lubricant delivery systems it was designed by WED in Cambridge, developed in Holland by SKF Mapro and is manufactured in Hungary.

Warwick uses the classic new product development process, that is, Stages and works closely with client marketing, engineering, finance and management.
Project Stages are:

Sign NDA 

A statement of the project’s aims and objectives.
A design is only as good as the Brief.
The Brief should describe the end user and the market.

Design is dynamic and exciting. But, it requires careful planning.
The Proposal includes work to be done and a budget for time and costs.
Projects are done in Stages.
Work starts on receipt of a Purchase Order.

Feasibility Study and Concept Designs
Some ideas, are they feasible to make and sell at a profit?

Design for Materials, Process, Finish and Assembly (DMPFA).
Detailed design study including function, appearance, assembly, tool and component costs, timescales, etc.

Models, Mock-ups and Prototypes

We do not work for free. But, we are as generous in sharing resources, information and experiences with our clients and guests as we can be. If you feel we can help, please ask.

A well designed product is an intelligent mix of science, engineering, technology and marketing.

Flying a Spitfire

This is Spitfire MJ772, a Mk9 built at Castle Bromwich in 1943. It fought in WW2 and was then converted to a T9 two seat trainer at Eastleigh in 1950. I flew it in Germany on Election Day in May 2015. It was the single most scary thing I have ever done!

MJ772 lives in ‘Hangar 10’ a private aeroplane museum on the island of Usedom on the Baltic coast. I can fly in it, with a pilot, for 1200Euros for 30 minutes. Seems ironic to be flying a WW2 British Spitfire from a WW2 German Luftwaffe airfield. The instructions were: weigh no more than 70kgs, the parachute will add another 6kg. I weigh 92kgs. I diet.

In 2014 I meet Charlie Brown, the pilot, a moustachioed RAF instructor. He is a lovely man whose hobby is building bicycle wheels. I was only just down to 74Kgs. I told him I would fly naked if I had to. Charlie said that would not be necessary as the Spitfire has 1600hp Merlin engine. We waited all day for the German Air Ministry to sign off the Certificate of Air Worthiness for MJ772. They didn’t. I went back to Blighty.

Three months later I went back to ‘Hanger 10’ for another attempt. It rained and rained and rained. We couldn’t fly because the field was too wet. I went back to Blighty. That was it for 2014. I came back in May 2015. The documentation was in place, the weather was hot, clear and sunny, I weighed 76kgs. I wore a bowtie. Charlie Brown and the Spitfire were waiting.

The ground crew helped me into the parachute, I climbed into the rear cockpit. It was very tight. It felt like putting a big metal knapsack on my back. I am strapped in. We are ready to go. (Tip: play this very loud!).

This is the original concept study for Printed-Light 1.
Printed-Light 4 is, er, very different.
