Quick, repeated cuts are what I am after. I plan to build a deck in the spring.
I have a lot of things in my garage/shop so everything is either against the wall, or needs to be easy to move. That's why I bought a table saw with a wheel kit.
For the miter saw stand, I figured I would make a small stand the same height as my table saw, and I can just clamp them together and use the table saw's fence to cut deck boards (or anything else like that.) If I need to make longer cuts I can add a bench, also the same height, and clamp a stop block to make repeated cuts. As long as the stands do not shift around, all I need to do is measure once.
What I meant by "rolling stand" is I want to put it on casters. Caster brakes are useless, though; the stand would shift. I will need to have a way to keep it in a fixed place.
I am trying to think of a way to use screw jacks that would lift the miter saw stand off of the casters and keep it stable. Obviously any screw jacks with feet are able to do this. I think I might be able to do it quickly if I take the long bolt that is part of the screw jack and replace it with a long hex-head bolt. Then an impact wrench can do most of the work and I can simply use a ratchet driver to level it out.
So the screw jacks would look like this picture, except the wing-nut part would be embedded into the bench and the top of the bolt would have a hex-head.
I don't know if the bases of these jacks are actually threaded, or if they are welded together or if the wing nuts actually ride on the bases. That seems like an easy problem to solve though, I could always get one threaded for me if they aren't.
Bolts like this 18" long are about $10 to $20 with a hex-head. It seems to me that this would be a really good way of having a portable saw stand that can be moved quickly and effortlessly, and will not take very long to level up, or adjust to desired height. I could make a couple of new benches this way also.
EDIT: If the wing nuts on those screw jacks do simply ride on the base, I guess all I need is a bolt with the same diameter and TPI, and a second wing nut for each one. Should not be too hard to get from the fastener store.
