Tom from One Fab Engineering in Blenheim, Marlborough, New Zealand

Meet Tom
Tom Healey is a seasoned professional in the stainless fabrication industry, with a passion for precision and a commitment to excellence.


With over 15 years of hands-on experience specializing in sanitary tube fitting and welding, Tom has become a trusted expert in catering to the unique demands of the wine, food, and dairy industries. His craftsmanship has contributed to the production of top-quality products in these sectors.


Beyond his career, Tom is a devoted family man who cherishes every moment spent with his loving wife and two children. When he's not busy in the fabrication shop, you can find him out on the water, pursuing his passion for boating, sailing, and fishing. And for those rare moments of relaxation, he enjoys the occasional round of golf.

Jim from One Fab Engineering in Blenheim, Marlborough, New Zealand

Meet Jim
Jim McCabe has over 15 years of hands-on experience in stainless steel sheet metal and tube welding, with a special focus on the wine and dairy industries. He was initially drawn to the precision of the craft, and that passion has driven him ever since.


When Jim's not in the welding zone, you'll find him on the sidelines at a rugby match. Rugby's all about teamwork, and those values have stayed with him from his own playing days and continues to influence his approach to his work.


Outside of the workshop Jim also enjoys a round of golf to unwind, or recharges at home with his young family who are a constant source of inspiration and purpose.
