MT Center Gauge

Keep yourself CENTERED

The MT Center Gauge eliminates the guesswork from precisely centering mortise and tenon joints. The precision-machined parallel arms quickly adjust to the stock thickness, placing the marking bar right in the middle. Just scribe each side of the bar and you’re done. Each marking bar is precision-machined from stainless steel (ideal for working with marking knives), and each has a pencil guide at its exact center. The parallel arms open to accommodate stock up to 2" thick.

Choose from four mortise and tenon widths (five for the metric system). Changing the width of your mortise and tenon layout couldn’t be easier. Simply remove the two thumb screws holding the marking bar in place and switch to the width you want. The imperial set comes with 1/4", 3/8", 7/16", and 1/2" marking bars. Or, if you’re like most woodworkers these days and work in both inch and metric depending on the project, the Deluxe Kit includes all nine marking bars. These are all the sizes you need for stock from 1/2" to a full 1-1/2" thick and more. 

The MT Center Gauge has been a popular OneTIME Tool over its handful of releases. Now, we decided to make it part of our permanent lineup. Like all of our tools, the MT Center Gauge is precisely machined and carefully inspected in our Strongsville, Ohio factory (just south of Cleveland).
