Highly recommend Todd for your machine shop needs in the Lycoming County and surrounding areas. He's very personable and professional as well as a great communicator. Awesome turn around time and quality work on cylinder head rebuilding and refurbishing, with reasonable and affordable pricing that is hard to beat.

I own a commercial auto and truck shop and I have been doing business with Simpson machine for almost 3 years now. Todd has machined many auto and diesel engine heads for me and I've had great results every time. I look forward to continue doing business here.

Does great work, no issues with multiple cylinder heads and lawn mower engines 👍
