PM-1440GT Features and Specsįor full specs and details, see the Precision Matthews PM-1440GT product page and PM-1440GT owner’s manual. Because of all this, the PM1440-GT would be a great choice for gunsmithing, toolroom applications, and as a general-purpose shop lathe. This lathe is suitable for high-precision work, can handle 2″ material through the spindle, and has great capacity (14″ over bed swing, 40″ between centers). The PM-1440GT engine lathe is a versatile machine tool because of the level of precision, the capacity, the features, and the pricetag (starting at about $8500.00 when this article was written). It’s going to be a lot of great content, so make sure you’re subscribed! The PM-1440GT will be featured in the lathe series, and I’ll feature the Precision Matthews PM-949TV Bridgeport-style milling machine in the milling series.

What’s more, I’ve partnered with Precision Matthews to bring you all a complete series of content covering the fundamentals of lathe and mill operation. In this article I’ll give you a complete walk-through of the PM-1440GT, evaluate its performance and precision, and share the tooling and upgrades I’ve added to this lathe. I’ve had this lathe running for over 6 months now (see my “arrival story”), and I love it. After a long search, I decided on the Precision Matthews PM-1440GT. It was painful to sell my Logan 11″x36″ lathe as I had put a lot of time and effort into customizing it, but I knew I needed more precision, capacity, features, and accessories/tooling. It was precision rifle gunsmithing that finally motivated me to “do it”. It’s been something I’ve contemplated, considered, and shopped for on and off for about 15 years.
