It's not usually difficult to get AC for my cordless drills, either. It's very convenient that I don't have to, though. OTOH, cordless saws are more marginal, but the later models are still useful. Like I said, I use mine to cut down sheet goods, though I just bought a more precise (corded) saw for this purpose. Many times the getting an extension cord out and putting it away is more hassle than the rest of the "project" (e.g. hanging pictures or curtain rods). Cordless tools are great for these small "projects".

I have 100' extension cords hanging on the walls of the shops, right next to the doors. I leave them plugged in, and just lift off the number of loops I need. They are about 5' per loop so it's easy to see what I need. I generally use the cordless drills to work on computers, and the regular drills for most other work. Like the 1/2" hammer drill with a 1" masonry bit. :) -- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge.

I have been able to remove some molded on strain reliefs by cutting off the wire and pulling it out of the jacket, then rolling the strain relief across the bench while pressing down. Generally, if you can break a small area loose, a few drops of water or alcohol will seep intp the cracks and allow you to seperate the rest of the jacket. -- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge.
