What Our Customers' Are Saying…

Best Quality

Is there anyone better than R.E. Thomas? Answer: NO. He is absolutely the most clever, and best machinist there is. Also, the best guy you will ever meet. He will never do you wrong, give you bad advice, or sell you a product that isn’t of the highest caliber and best quality on the market.

Bill Faulkingham

Beautiful Hardware

"I just wanted to thank you for the bushing I received today, As usual, you made them perfect. Ron, I can't thank you enough for the beautiful hardware you made for my boat. It all looks so good, I hate to mount it on my boat. I want it to hang on my walls of my family room! He, he, he! Also Ron, you've been nothing but a pleasure to work with. I will always keep you in mind when I need some custom machining done."

One of the Best Investments We’ve Made

"We bought a set of Piranha Line Cutters 6 years ago, one of the best investments we've made. Haven't had to call a diver since. Great investment for a commercial crab boat."
