True Bore Alignment System In-Depth

Also published on our sister site: Ultimate Reloader. If you’re working as a gunsmith on rifle barrels, actions, or related parts, chances are that you spend a lot of time with critical alignment. Every time you go to machine these parts you’ll need precise alignment with your lathe spindle. And these alignment tasks can eat […]

DRO Install on Precision Matthews PM-728V-T

No milling machine is complete without a DRO, and I’ve finally installed one on my Precision Matthews PM-728V-T! Now I can use this machine to its full potential! In this article I’ll give an in-depth review of the MagXact magnetic 3-axis DRO that’s optional with the Precision Matthews PM-728V-T. What’s In the Box Here’s all […]

How-To: Align Z-Axis Power Feed Install for Precision Matthews PM-949TV Mill

If you’ve run a Bridgeport-style vertical milling machine, you’ve probably worn your arm out cranking the table up and down. I know I have! And now it’s time to add a much-anticipated Z-Axis power feed for my Precision Matthews PM-949TV milling machine! What’s In the Box The ALIGN Z-Axis power feed comes with everything you’ll […]

Hands-On: NEW Precision Matthews PM-728VT Precision Bench Mill

I decided it was time to add another milling machine to my lineup! And this time I’d go smaller- I already have a Precision Matthews PM-949TV (9″ x 49″ Bridgeport clone), but for some jobs, smaller is better. It will also be nice to have a mill that I can leave setup for things like […]

Building the ULTIMATE Lathe Spider For Your Lathe

One of the first things I do when I get a new piece of machine shop equipment is to decide how I’ll “customize” the machine and organize all of the tooling. Machining is a very personal thing, and it’s therefore “just a part of the process” to get things dialed-in and setup the way the […]

Lathe Fundamentals 101: Lathe Safety

HERE IT IS EVERYONE! Lathe Fundamentals is officially underway, and I’m kicking it off with one of the most important topics, lathe safety! This series will span several years, and will be broken down into 100, 200, 300, and 400-level topics, each in a series. Please explore the navigation at the beginning and end of […]

Precision Matthews PM-1440GT Lathe In-Depth Walkthrough and Demo

For years I’ve wanted a high-precision engine lathe. It’s been something I’ve contemplated, considered, and shopped for on and off for about 15 years. It was precision rifle gunsmithing that finally motivated me to “do it”. It was painful to sell my Logan 11″x36″ lathe as I had put a lot of time and effort […]

3-Phase for the Shop: Static Phase Converters -vs- Rotary Phase Converters -vs- Variable Frequency Drives

So you are the proud owner of a heavy piece of iron with one or more 3-phase motors. Welcome to the club! These machines old and new can represent a great bargain either at auction, or via private sale. Heavy machinery with 3-phase power is difficult to move, and requires a power conversion option if […]

iGaging EZ Data Micrometers: Overview, Measurement, Data Logging

When you get into serious precision work, you need the ability to measure with a high degree of precision and accuracy. When I’m chambering match-grade rifles, “tenths matter” (0.0001″). When I decided to upgrade micrometers, I knew I needed tenth-level resolution/accuracy, and wanted to cover a 0-3″ measurement range. The new iGaging EZ Data micrometer […]

3-Phase for the Shop: 3-Phase -vs- 1-Phase Power

As a Mechanical Engineer, electricity and power have always been a touch of a mystery. I can recall my Electrical Engineering classmates talking about things like phase diagrams and other “non-mechanical” things that were fascinating, but very different from what I was studying. Since then, I’ve learned a lot about wiring and power. Having wired […]
