Moore & Wright
Baty Baty has a rich heritage dating back to 1932, originally specialising in the manufacture of high-precision dial indicators and cylinder bore gauges. The company later diversified into non-contact measurement, introducing Optical Profile Projectors and the renowned Baty ‘Shadograph’ series, which set the industry standard and are now proudly manufactured in Bradford, England under the Made in Britain accreditation. Building on its gauging expertise, Baty expanded through the acquisition of John Bull and British Indicators, adding calipers and flexible fixturing to its portfolio. The range evolved further with the introduction of pioneering camera-based Video Inspectors, enhanced by Video Edge Detection technology to deliver greater accuracy, repeatability and speed. Today, this legacy of innovation continues with a new generation of vision and inspection technology, including the high-speed Baty Velo FV for volume manufacturing, alongside the versatile Baty Venture FV and Baty Venture FH. Since joining the Bowers Group in 2010 and relocating manufacturing to Bradford in 2023, Baty has further strengthened its capability to deliver advanced metrology solutions for modern manufacturing.

XTHSY Pistol Grip Bore Gauge with Indicator
BORE GAUGING Engineering Students at Weymouth College Benefit from Bore Gauge Donation CASE STUDY
The XTHSY Pistol Grip bore gauge is a useful option for those requiring pistol ergonomics with a large digital indicator. The LCD digital indicator fits into a standard 8mm clamping shaft at the rear of the pistol-grip. Pistols of this type are available for all measuring heads in the XT range.
equipment likely to be encountered in industry. Engineering student Louis Poulter said:
Geoff Williams, Lecturer in Engineering at Weymouth College said:
The XT Digital Bore Gauge from Bowers Group is of great benefit to my students. It allows them to measure internal dimensions, including bore diameters, to exceptionally tight tolerances. We are delighted that Bowers Group has kindly donated the bore gauge to the college, and that they recognise the value in contributing to the quality education of the engineers of the future. It’s great that the students understand that time is money in industry, and that investing in a decent piece of kit can eliminate expensive mistakes, therefore reducing scrap. This guarantee of accurate measurement allows businesses to make up the cost of kit quickly, providing a great return on investment. As part of their engineering qualifications, the students at Weymouth College need to be able to demonstrate that they can carry out a range of measurement techniques and use the equipment competently. The college required students to carry out the inspection of a shallow 40mm bore, but previously could only offer digital calipers to perform this task. Unfortunately, in relatively inexperienced hands, the digital calipers were not nearly reliable enough. The college, therefore, needed an instrument that would be better suited to inexperienced hands, in order to achieve the measurement task required and enable the students to demonstrate their competence with metrology equipment to meet the demands of their Engineering course. Bowers Group supplied Weymouth College with an XT Digital Bore Gauge Set, with a measurement capacity of 20-50mm. The XT digital internal Micrometer boasts a large, clear LCD display and IP67 electronics protection. Its proximity output allows bi-directional communication, giving greater flexibility for data acquisition and storage, which could be useful for the collection of SPC data in a later part of the students’ course. The extended mechanical travel of the XT range means that special heads can also be manufactured to accommodate users most awkward measuring problems, for example; threads, splines, slots, grooves, deep-holes and many more applications. The bore gauge is perfect for use at Weymouth College. The ratchet stop ensures consistent measurement, and the precision setting rings mean that the bore gauge is set and ready for the students to use. The 3 point design means that the bore gauge naturally centres itself in the bore, making measurement quick and simple, and unlikely to be mistaken by the students. It is also more representative of the
The Bowers Group bore gauge is clearly much more advanced than anything else available. It’s really accurate and reliable, so perfect for measuring the dimensions of components. To illustrate the fool proof nature of the bore gauge, 2 engineering students used it for the first time and compared measurements. Although they had only been briefly shown how to use it, the first time they handled the bore gauge and made a measurement revealed only a micron difference in their measurements, which is the equivalent to one thousandths of a millimeter. Bearing in mind that the width of the average human hair is 75 microns, this is an exceptionally small discrepancy in the two measurements taken by extremely inexperienced hands. More traditional methods of measurement, for example; calipers, micrometres, and telescopic gauges, do have their drawbacks in an educational environment. Although a skilled inspector can achieve accurate results with a good level of experience and practice, students often find them fiddly and struggle to achieve accurate, repeatable measurements. When measuring bores, students need to make sure that the micrometer in use is placed exactly over the widest part of the hole in order to achieve an accurate result. And with Vernier calipers, excellent eyesight is needed to read them to 100th of a millimeter, therefore differing measurements from operators can occur. In addition, equipment such as this needs calibrating once a year, which takes time and can be expensive. Geoff Williams continued: Throughout a long career in Engineering in the Defence industry, mainly at the Defence Research Agency and its predecessors at Portland, I have been a keen advocate of Bowers Group’s 3 point bore Micrometers. Their accuracy and ease of use have saved my employers a great deal of money over the years, not only by speeding up the measuring/inspection process, but also by reducing errors and scrap.
