Why is this? Wouldn't it be easier and more accurate to put a square on the corner? Stephen Danago Merritt Island, Florida A In small boxes and very simple assemblies, using a square would probably be sufficient. When projects get larger and more complex (for example, a cabinet that has several internal compartments), checking a couple of corners with a square does not give you a reading of the overall project — just those specific sections of the piece. The comer-to-comer diagonal measurement technique is not only fast and extremely accurate, but it is also very helpful during the assembly process. As many of us have discovered, when you are in the middle of gluing up a project — a step that, as Ian Kirby likes to point out, is not easily reversible — it is not uncommon that the clamping pressure is applied unevenly and measuring from corner to corner across a clamped-up subassembly is that you can quickly check to see il thai is the case. If your project is a bit out of whack, you can change your clamp positions and clamping pressure while the glue is still wet and get the assembly square and true before the glue cures. — Rob Johnstone Q1 am looking to buy my first miter saw. Is it worth the extra money to get a saw with dual bevel? If I buy a single-bevel saw, how will it limit the saw? Jason Schultz Englewood, Ohio April 2010 Woodworkers Journal A If you're planning to install lots of crown molding requiring compound miter cuts, a dual-bevel miter saw will give you the full range of compound angles, both right and left, without having to rearrange your moldings 011 the saw to cut them. But, for general woodworking, a single-bevel miter saw might be all you need. That's the type I own, and I've used it for more than 10 years without wanting for more. Generally, they're less expensive than dual-bevel models. Either way you go, buy a 12"-diameter saw to maximize your crosscutting width and thickness. — Chris Marshall Q1 have heard that keeping rechargeable batteries in the cold is damaging to them. My shop is only heated in the cold months when 1 am doing a project. Should I continue to bring the batteries and chargers in, or can I keep them in the cold and continue lo charge them? LaMar Burns Bountiful, Utah Measuring diagonally across an assembly is a fast and easy way to see if it is square. |
