@Mario Turcot not sure what all you want out of these things. Overall height adjustment can be increased with shims but earlier you said you wanted “micro adjustment”.

Technically, to get the 1/1000” adjustment that implies down here in the Imperial States of America (not sure how fine “micro” is in a metric realm) you’ll need to find a way to turn the screw in 1/100 revolution increments. But, even with a 1/2”-16 thread screw you have to measure out 1/50th turn increments. You probably don’t need that fine of adjustment.

Also consider genuine leveling pads like these

https://www.mcmaster.com/leveling-pads

The little “10-32 nickel plated steel leveling pads” can support 700# each and have 2” of thread for $5 a piece. You’d need to make a mounting plate from 1/4” steel. With a screw that small you’d need to protect it from lateral force but with a long enough wrench you could easily subdivide a revolution into .0001 increments.

My apologize, I should have express myself a bit better. By micro adjustment I meant more in the 1/16 increment. There is many hydraulic/air compressed system I could have look at but those aren't accurate, unless you put the money on the table. I understand that it's hard to figure out what I want without having a concise idea of the table and it's components.

In essence you have a rolling cabinet (32" x 54") with a top (36" x 58") sitting on it. The top being a torsion box. The cart will most of the time being used as an outfeed table for the table saw. When I want to make an assembly I simply move it away from the table saw and work from 4 sides. Since my floor have a central drain with a ~1" pitch I want it to stay flat. The torsion itself is not rigid enough to compensate for any uneven surface. That's why I want to be able to slightly adjust each corner individually. I might Not need to make any adjustment at all. But better be happy than sorry  [tongue]

My fault, only skimmed the thread.

Sounds like the floor is the problem. If it isn’t too late you might use adjustable height locking casters.

These only have a half inch range...

Those casters look pretty sweet. I already have the casters and like you said floor is the problem. What i am really concerned is to mitigate the torsion box distortion. I will give a try to what I found at LV and see if it keeps the surface flat.

On another note, I will incorporate the Vac-Sys into the table. The Pedal will be in the front center fixed into a little cove like on that thread and the pump will be on a shelf close to the top. Not sure yet about the position. In the event that I want occasionally to move it out of the cart can I use stander air pressure quick connect? The bases have a quick connect on the body but the pedal and pump are fixed.

Hi Mario. I'm still not quite sure what you are trying to achieve...are you trying to level the entire outfeed table, or just the torsion box top? I have those levellers you showed in this thread, and as said earlier they are pretty course threads...and they are not a tight tolerance and tend to wiggle a bit...having said that, I haven't used them on a bench with that kind of weight....If you are looking to just level the torsion box I remembered watching a outfeed table build by downtoearthwooder and he used tee nuts and floor levellers that I have also used before, and they don't move.....here's the link if you haven't already watched this series. I think he shows in part how they work around the 10 minute mark..but he drills a hole in the top of his table for access....

The torsion box only. I know a picture worth 1000 words  [scared]

First the torsion box alone will be around 80lb. It's made of 1 sheet of 15mm, 2 sheets of 12mm and 1 sheet of 18mm. In addition I have 2 t-tracks on the long side in the front. The T-tracks are for any clamping needs but mostly to hold and position the vac-sys bases.

On the bottom side of the torsion box I bore 6mm inset on each corners (possibly 2 more in the center). The insets are to keep the torsion box in place where the "levelers" will protrude. I actually have that part figured out, it will not be a micro-adjustment but at least some way to have the torsion box somehow flat.

I'm now at the base where I will have storage on each sides. Once I have the base constructed it will be easier to get a good picture of table.

I came to this late and see you have the leveling figured out, but I would recommend bolts and nuts to level the table.  I used that method to level a miter saw on a stand I built a decade ago.  Works well.

It works well and is relatively simple.  I can’t claim the idea, but I don’t recall where I found it.  Just for future reference if necessary I will add one more photo

More pictures


The above picture shows the frame where the "levelers" (6) will be installed. That from will be on the top of the rolling cabinets. A similar frame will have the wheels on it and will support the whole table.

The above picture shows how the "levelers" will look. The Torsion box and the MFT top will sit directly on the "levelers".

I Hope this help to figure out what I want to achieve.  [big grin]

*UPDATE*
Adding the Vac-Sys tracks

Only the track on the edge is installed & taking measurement for the second track.

It's coming together slowly  8)

One more

Now that the two tracks are installed, I'm working on the 18mm piece that fit between the tracks. I have to make a rabbet on each side to accommodate the tracks. Next is the facing to hide the ply layers  [big grin] The top is about 75lb right now and if I lift it from one corner, there is no apparent bow. it's pretty stiff and rigid   [scared]

I was planning to use poplar, but poplar is a pretty soft wood. Any suggestion that will not break the bank?

This will round up the top, next is the base.

The actual cart you see under the top will be converted into a dual flip top for the thickness planer and oscillating sander units. Similar to

What is available in your area for a reasonable price? My preference would be hard maple and my second choice would probably be soft maple.

Thanks for the suggestion. I only need 20' so maple should fit in my budget.  [big grin]

For future reference, do you think I can trust that chart. Not all wood are listed but does that gives me a good representation of NA wood hardness?

Mario,

Thanks for sharing the Fisher's clip. His 180* swing design is unique and better than the usual one. I also found his video easy to follow (good pace of delivery), with no distracting or annoying music throughout.

@ChuckM I like that one a lot. The only thing I would add is a open closet switch for each tool. That way only the tool on the top can be powered.  [big grin] or a simple limit switch



Oh and even better. An electro magnetic switch that will control both tools at the same time prioritizing the one on top. Yeah that's how I will make it  [wink]  Now I only have to brainstorm a way to hook up dust collection.

I forgot to mention that he is good with keeping his talking to the subject matter with little to no unnecessary explanations (I call it the Norm Abram style), and hence his video length is well managed. I went to his youtube channel, and found his project videos are 15 minutes +-, others mostly 5 to 10 minutes.  I'll scan them out to see if anything is worth my full viewing.

@gnlman yes I watched that video at least 4 times  [big grin] I'm slow to build something and that table would take me a few years to put together  [embarassed]

lol...at least you have started your project...mine still in my head speaking of slow.....hahaha

Yes he's very detailed...but was only meaning for you to check out his table levelers....but appears you have the issue solved nicely.

Found that cutting board that fit perfectly the size of the vac-sys base

The board will help sliding the base onto the tracks and also protect the vac-sys rubber seal/feet

Not much done on the weekend  [embarassed]

The vac-sys base glide like a champ on the tracks  [big grin]


I shop around for hard maple for the edges and it was $200 from home depot  [scared] Going to pick up some at my prefered lumber yard this morning.

All that need to be done on the top is the edges, sanding and finish. Tackling the base design today. It's going to be a multi-bay type base. something like this
