Machine shop tools in Miniature

Barry Jordan with the model Bridgeport mill that first brought him to international attention. (Click photo for larger image.)

Introduction

Barry Jordan’s models first came to our attention after an article about his 1/5 scale Bridgeport mill and the tiny rotary table that led to it appeared as the cover story in Model Engineers’ Workshop in the December, 1997 issue. The Joe Martin Foundation’s first winner of the Metalworking Craftsman of the Year award, Jerry Kieffer attended a model engineering exhibition in England in 1998 and got to see Barry’s models first hand. Over the years we have followed his progress as he turns out machine after machine, each to the same superb level of quality and detail. What impressed Jerry the most about Barry’s machines in addition to the quality was the fact that they all work. These are more than mere models, they are functioning miniature machines capable of doing the same jobs as their full-size prototypes but in smaller scale. Although it would be difficult to tell from the finished models, no castings were used in their production. All parts are machined from billets of solid metal.

Barry Jordan was selected by Joe Martin to become the seventh recipient of the Joe Martin Foundation’s “Metalworking Craftsman of the Year” award for 2003. Mr. Jordan will be attending the 2003North American Model Engineering Society Exposition in Detroit April 26 and 27, 2003 to receive his award and a check for $1000.00. He will be displaying some of his prize-winning machine models at the Sherline Products booth and will be available to discuss them. We encourage all who can to attend the show, as it may be the only opportunity to view these outstanding models firsthand in America.

BIOGRAPHY

Barry J. Jordan was born in Derby, England in 1945. He left Joseph Wright Art School at 15, and secured an apprenticeship with Rolls-Royce Aero Engine Division, Derby in the experimental department. After developing a range of ultrasonic crack detection equipment used in non-destructive testing, he formed his own company in 1977 to manufacture this equipment.

In 1994, Barry was diagnosed with an inoperable brain tumor. Fearing the worst, he sold the business to Rolls-Royce and Associates, bought a Myford Super 7 lathe, a Raglan milling machine, built himself a workshop and went back to his boyhood love of model engineering. Fortunately, his tumor has responded well to medication and he is still turning out wonderful models from his home shop.

Barry is seen here with some of his models at a recent model engineering exhibition in England. Magazine cover photos of his machines adorn the blue backdrop. (Click photo for larger image.)

His first project was a one-inch scale mini traction engine. Then, looking for a theme different from the normal models seen at all international exhibitions, Barry decided to start making miniature classic machine tools. In 1997, he produced his first; the award winning 1/5 scale Bridgeport BRJ mill. This model took Best in Show at Harrogate, England in 1998 and has gone on to win many other awards in the UK. Barry is now working on his eleventh miniature machine, the Swedish made Tricept 805 five-axis machining center—quite a challenge. He says that his hobby has been part of his therapy.

Building the 1/5 AND 1/14 Scale Bridgeport Mills

By Barry Jordan

Bridgeport milling machines have a special appeal for me since I built my award winning 1/5 scale model back in 1997. I have now built a second model Bridgeport, but this time it is the ultimate in miniatures at 1/14 scale. This has to be the smallest working BRJ made to date. The overall height of 7.800 inches is from the base to the top of the motor case. Inside the case is an extremely small Swiss made electric motor. This is rated at 1.5 volts, but I am running it on a 3 volt battery concealed in the base. In the earlier stages of building the model I did consider having the motor in the base alongside the battery pack. This would have allowed a larger, more powerful motor to be used. However, because I wanted flexible movement of the head in all directions and the sliding ram to function as in the full size machine, I soon concluded that this idea was totally impossible to produce in this scale, so I reverted back to mounting the motor in the correct location as in the full-size prototype.

To complement the model I have also made a machine vice and a matching rotary table .800 inches in diameter. The small table has a ration of 60:1. Two miniature T-bolts secure the rotary table to the machine. To cut the actual T-slots, I had to make the milling cutters myself as no commercial equivalent miniature cutters are available.

Building this miniature was a challenge which I enjoyed executing to prove a point. Jerry Keiffer's beautiful little models (which appeared at Olympia in 1998) were such an inspiration to me that I had to try to emulate his excellent craftsmanship and show that we British are as capable of precision engineering projects as our American friends. I do not intend to do any further work in this scale as the parts are too fragile to make working models. Any future projects will be in my preferred 1/5 scale.

Here are several examples of Barry Jordan's work:
