I would think casters on the corners would keep it from tipping with a heavy load placed on the end.

If you don’t want to do 6 or 8 casters…how about the 4 casters towards the center as you said, then some adjustable feet on the corners. That would help you level it on the uneven floor, then retract/remove them for moving. If you’re able to lift the corners just a little, it could be as simple as a block of wood.

Go to my Blog, and look up “A new look for an old workhorse”, and you can see how I built the saw cabinet when I re-furbished my old Craftsman table saw….Look at how I built the platform for the base to sit on….Braced up underneath and casters on each end…I later put 2 more casters in the middle, and levelers front and back….This will give you some idea of how to build a support platform, and then go from there….

^^ This. However, I’ve found my workstation is heavy enough that I hardly ever need to lock the casters. It reminds me of football practice back in high school when we had to push around the blocking sled.

I find the problem with locking casters is; you can never get all 4 casters in a position where all the brakes can be applied. This is true of small casters, those around 3 or 4”. Large casters, like the ones used on hospital gurneys are accessible for locking, but the smaller ones get hidden under the framework and don’t leave enough access for your foot. At best, only 2 casters can be locked and it still takes some maneuvering to get the platform into locking position. So, what is the solution? Use retractable casters that allow the platform to rest solidly on the floor.They cost a lot more. Moving the casters toward the center of the load really doesn’t answer the problem. By placing them at “far corners”, increases stability as table saws tend to be top heavy. I would not use more than 4 casters. When I built a platform for my cabinet saw, I wanted to use large casters, like 5”, but that would place the saw top too high above the floor, so I made the platform to accommodate 5” casters, by welding offset pieces at each corner. That kept the top 36” above the floor. Recently, I finalized the position of the saw in my shop and have discarded the mobile base. I hope some of this helps you.

I don’t see why moving the casters inwards would decrease stability, and by moving inwards I mean side to side, not front and back. The 2 front and 2 rear casters would still be at the outer edges of the base, but instead of having them at the far left and far right ends, I’d move them in closer to center by roughly 18-20”, placing them roughly 40-44” apart from each other.

Then combined weight of the 2 saws will primarily be in the center of the workstation and take up about 40” of it, so I don’t see the possibility of it tipping when working a heavy project or stock on either the left or right end.

If you go back and look at my saw station, you’ll see that I had removed the casters in the middle of the platform, and just used the ones on the outer edges of the platform….I then added levelers to each of the corners to adjust the height of the cabinet….My out feed table is between my two saws, and neither one of them moves….The levelers help stabilize the cabinet, and makes the height where I need it to be level…..The casters do not move unless I want to move the saw, in which case I don’t…..Only to check the oil in the motor, or change a belt out….or check the pullys…...So some things that some people tell you just doesn’t hold water….It’s your saw station…...do it like you want to…..!!

The one I made for mine uses 6 casters. (I didn’t post it as a project). I use 2 on either end and 2 i the middle. I have a craftsman 21833 saw and a router on the left wing. The rest I made into storage.

I’ll try and take a picture later tonight. My thought is for the weight you are projecting, would be to have something in the middle also.

I made one for my delta saw with 6 casters.

The base is an open torsion box underneath. if you think of a torsion box without one of the panels. I made the base from a 3/4 birch ply and 3/4 torsion frame all glued together. no screws except for the outside frame. I then put 1 caster in each outside corner inside one of the torsion box holes. Then another 2 in the middle on the outside of the frame.

I then just capped it with a 3/4 cedar panel for aesthetics

Locking in place was easier with just 4 toggle clamps. see in picture. the ends can be hand adjusted for height to lock the roller base anywhere in my garage… which does not have a level floor due to a floor drain in the middle of the floor. depending where I use the saw, the toggle clamps have to be adjusted to where it sits.

Most of the time i only use the 2 front toggles to keep it in place. there are 2 more on the back side outer corners, but are rarely needed

Having 6 wheels does make it rock sometimes when moving around, but all 6 rotate and it just takes a little man handling to get it into the place I want it..

So far i have been using it a couple years without issue. added more cabinets and storage to it as well as dust collection and a folding outfeed table.

it caries a lot of weight and still moves easily.

Also, as for the racking or twist. there is none. the base is so stiff that as I move it around, it may rock on 3 or 4 casters . the base does not bend at all.

if you put bigger toggle clamps on it, you can lift the entire unit off the ground and with enough adjustments actually level it on a non-level floor.

If I was to build a mobile station for my tablesaw, router and have storage on it as well, I would look into building the base with a torsion box. I have a cabinet under my drill press that I built with a torsion box frame. There is no room for casters except on the outside corners. It’s one heavy son-a-gun but doesn’t sag anywhere and the casters work fine.
