During construction, get the building stabilized with regard to temperature and humidity prior to installation of finish materials and interior trim.
Cords for small power tools like sanders and drills can get in the way when you work on a bench. One trick to keep them from interfering is to make up a chain of heavy rubber binders. Loop one end of the chain onto the cord about a foot behind the tool. Loop the other end over a cup hook screwed into the ceiling of your shop. When done, unhook from the cup hook and put the tool in storage.
Install a carbon monoxide detector to warn of harmful gases that may be entering your home because of a blocked or damaged chimney or faulty heating system.
Here's a tip on how to increase the life of old wooden gutters. The first step is to lay a new rubber liner along the inside the gutter. Adding copper flashing along the edge seals the liner, adds extra durability, and allows water to run off easily. Finally, add a second strip of rubber on top of the flashing for extra protection.
The width of your bandsaw blade and its tooth set will determine the smallest circle you can cut without damaging the blade or the saw guides. Generally a 3/16-in. blade will cut a radius as small as 5/16 in.; a 1/4-in. blade will cut as small as 5/8, and a 3/8-in. blade as small as 1-7/16. The wider a blade, the thicker it will be and the longer it will stand up and keep its edge.
As with hand planes, the key to using chisels successfully is keeping them sharp. If they are not kept sharp, your work will suffer. If you are wary of taking your good chisels to the stone, consider buying a cheaper set to practice on. Store your chisels boxed, in a tool roll, or in a wall rack. Avoid magnetic tool racks; when chisels are magnetized small metal filings will cling to their edges, making honing more difficult and dulling a keen edge much faster.
Buying tools in sets dramatically reduces the cost, and you'll have a more complete selection when you need it.
There's a solution for dealing with wood screws which have broken off below the surface of the wood. If you don't want to risk damaging the wood by digging it out, try driving the screw deeper into the wood with a nail set. Then just fill the hole with a wood filler, and drive a new screw next to the broken one.
Remember that extreme temperatures can build in an attic without proper ventilation, especially with a dark colored roof.
If you plan to refurbish a major shop tool or other equipment, take some photos before you start. They possibly can save you some head-scratching during the reassembly process. Take pictures from a number of angles, and take close-ups of areas where you think you might have some questions later. The more complex the machine, the more photos you should take.
