I know there are these things you put on a spinning arbor
on a miter saw, but I want one for setting up a joinery
thing and there won’t be a spinning arbor.

Anybody know about a basic laser line device that
doesn’t need to spin but projects a line from
above?

Try a laser pointer. You can find them at office supply stores or Harbor Freight.

I have an aftermarket attachment on my drill press that projects two lines that, in theory, will indicate where the drill will drill the hole. Half of this will project a single line.

There are several models out there in the Big Box stores. Black & Decker makes one, “Sure Grip”, that fits easily in your hand, is battery operated, has a level vial on top, even has a suction cup to attach it to a flat surface either vertical or horizontal,and project a red laser line about 12-15 feet. Seems to work pretty well for such tasks as hanging multiple pictures on the same plane. I don’t know your tasks. I use a lase that is part of my DeWalt compound miter saw that is GREAT.

Loren, a few months ago, I purchased a few laser levels from Bosch, Dewalt, CST-Berger, Skil, etc.

The problem with using any of those, while providing a great reference for rough or large scale work, is that they all are terrible at fine detail.

In this link, http://www.southernsprout.com/projects/tools-and-projects-to-come/ (scroll down (from my (our) blog)), you can see the issue you’ll be facing with most laser levels. The CST used a rotary mirror/prism to project a “plane”. The others employed similar but not rotary. The lines were way too thick for precision work, but work great for foundation measurements, gutter alignment, picture frames, cabinetry, etc.

I think I have found some inexpensive things that might
work. You can get what is more or less a laser pointer
with no power supply but with a lens that flares the
beam on a 60 degree angle.

I found these lens units are made to a wide range
of standards though.

I only need to project a line about 6” long from a distance
of about 12”. It’s just for simplifying setting up of cuts
on a machine I use for cutting tenons.

To help all, I believe they are called “Fan” lasers when they spread the light, use that term to search.

here is a link to a number of “FAN” lasers. Although loren with your go gettum spirit you’ll probably figure it out much cheaper.

Here
is another resource for the diy types

Thanks all. The Harbor Freight item might work and
be less of a hassle to try the idea out with since it
has a mount and a battery wired in already.
