With a small one-person shop, it helps to have supports and guides to handle materials. With the table saw blade under the work most of the time, it would be nice to know where it is at all times.
I had a couple of laser lines that I wasn’t happy with because it was very difficult to get them level especially over long distances. Also, the batteries were always dead when I went to use them. They have found new use in the shop…
I purchased a 3 Volt transformer from Aspire Technology Solutions and wired in a pigtail so that I may use it with batteries if I need to. Plugging it into the light outlet made it easy to control.
