towdude3...That is correct; 3 legs are better than 4...Check out this link that explains why:
http://mathforum.org/library/drmath/view/53267.htmlI have a dremel 1680...I've read that the inline orientation of the motor is a major contributor to the excessive amount of vibration...Other (higher quality) saws, such as Dewalt, Excalibur, Hegner, etc, all have the motors mounted sideways instead, which is a more natural setup that uses a simple cam to make things happen...The inline configuration uses a cam as well, but also needs to use additional parts in the linkage in order to "twist" the direction of motion 90 degrees so it can make the arm go up and down.
Mounting a saw like the Dremel to a
sturdy stand takes care of most of that vibration...Something else to look at is that the Dremel manual highly recommends (almost mandates) mounting the saw, whereas the Excalibur manual simply states that mounting is optional...The Dremel manual also talks about using padding between the saw and the stand...A lot of the manuals for the higher end saws don't even mention anything about needing to use padding...If/when you start looking for an upgrade, take a look at the various saw brands user manuals; they may give little hints like this that might help you make the best decision.
