Those of us that do hand-tool woodworking to any extent are intimately familiar with the marking gauge. This little gadget allows measurements to be transferred accurately and repeatably time after time without the need to use a rule. Once set, it doesn’t change.
This post was prompted by a comment that Todd Clippinger made on Twitter concerning his current stable of 15 (yes, FIFTEEN) routers. He said that, once a bit was installed and adjusted, he often would not move it until the end of the project, thus necessitating several routers. It occurred to me that marking gauges are used the same way. A gauge is generally set once, and not changed until all joints requiring that setting have been marked.
So, how many marking gauges do you have?
