"Just a short note to let you know how we feel about your products. Our company produces high quality, split-bamboo, fly rods for a rather small group of demanding fly fisherman. We started in 1960 and are pretty proud of our collection of testimonials. We are happy to tell people about how satisfied we are with yours. We use your J-4 to drive the cutters on our milling machines. We could have chosen something less expensive, but honestly feel we made the right choice with going with Themac. Your
products are the finest of quality, well designed and expertly manufactured."
Charlie and Steve Jenkins
We have been using this J7 style Themac grinder for over 30 years now and it continues to provide us very accurate results with a predictable reliability at a very competitive price. Other P&WES facilities have tried competitive products and all have switched to the Themac J7 model grinder motors. We really appreciate the quick turns on the removed units.
