I have been working with this father son duo for some time now, a little over a year. And I cannot express enough the amount of gratitude that I have for being referred to them. Every idea I've ever thrown at them they have been able to bring proof of concept and so much more. Whether small jobs like tapping helicoils to welding, or bigger builds like prototyping and milling, Topline is my go to. Every machinist that I've met there are very skilled and knowledgeable. Joel especially is very patient and informative. He doesn't act condescending even though my persistent questions probably deserve it! He's given me great guidance on how to improve on my CAD work and always offer suggestions and improvements. They are a gem and I hope they stick around for a long time.. otherwise I could be out of business with out them! read more
