Large Scale Layout Tools

Make a T-square and compass sized for big layout tasks. Enjoy the accuracy for years to come.

I find the issue is that most layout tools live in one of two camps: they’re either small and precise tools for fine woodworking, or large, cheaper tools for rough-in carpentry. Of course, some manufacturers do offer layout tools that are both large and precise, but they can get expensive quite quickly. Our answer to this quandry is the tools you see above: a shop-made T-square and compass, both sized for large projects. These two offer size and accuracy, while also boasting a low cost in materials and even lower cost in time. As you can see above, these two tools couldn’t be simpler. The head of the T-square is kept at 90° by a dado, and its blade is stiffened by a pair of aluminum bars. As for the compass, a lap joint connects the two arms at the fulcrum, while they pivot on a thumbscrew and lock on an aluminum slide. The slide is routed to shape from sheet stock, and the pivot needle is shaped from low-carbon steel. These tools are certain to improve your large-scale layouts, and all they’ll cost is a few pieces of wood, a handful of hardware, and a pleasant day in the shop.
