The table is very stiff, just use a thicker top so that the clamps don't deform the holes in the top, I have built 2 like this, the second one I did as little welding as possible and it is pretty flat, maybe a sheet of paper can fit under a straight edge in places.
The plates the legs bolt on to...
The biggest problem with the thin top is the clamps distort the holes, it doesn't take much force, the table can be stiff enough if it is a reasonably designed box.
I don't want to be captain obvious but the reason it was bakelite was to insulate the engine heat from the fuel pump, hopefully he never drives it and takes it everywhere on a trailer. Fuel boils , engine stops, wait a long while and get going again!

Just a tech question, why would the trunnion need to be shimmed, this was a 5 axis machine with a center of rotation in space somewhere, doesn't that get handled by software and parameters, mrzp?
In your " long run time / quick swap over " situation a second spindle seems like a better idea, it also gives redundancy for doing maintenance or possible breakdowns, you are not relying on just the one spindle. Cheaper to just duplicate what you have as well.
I do some similar work, I don't use a fixed number of repetitions per bar as it is a recipe for trouble if a bar is cut short, our material lengths can be supplied random from 5 to 6.5 meters and are not always cut up / divided into exact lengths.
Anytime you walk up to the machine you can look...
The trick to be making that at a competitive price is that you have to be making thousands of similar items to keep the mandrel bender, turret punch, press brake, powder coating line, packaging dept. and so on busy for the rest of the month. If you take all the processes to make that part in...

I have ripped the blades off a few of the budget fans, it is the sudden change from blades hanging vertically to be being fully extended horizontally that does the damage, the blade gets a mark or dent from the stop in the housing. By starting at a lower speed around 1000rpm gets the blade...
Staying with the cobot method, if you cut the stock to the required size before the sanding it means you don't need to be so careful with the subsequent handling.
Do all the cutting and machining operations first so as to use the cobot to handle small pieces against a stationery belt sander ...
What about running the cutter offset to a side, so that the outside edge of the cutter just cleans up, pretty sure it is not the problem here but is it not better to run a face mill so that the cut is not completely centered, what I mean is that there is a side force on the tool pushing either...

What do you have coming, I also use your double station vices and am in the process of automating the loading with a cobot, strip parts, 30 to 60mm wide and up to 220mm long,
Thanks
Ok,
back on to the topic,
I am also in the process of adding a parts loading cobot to a vertical twin pallet machining center. The robot is on the way, grippers are decided but the next big deal is the in machine work holding.
The work I do is all aluminium cut from flat bar, 25mm wide to 100mm...
I originally purchased a Fanuc / Lincoln package as a foot in and learning setup. It did help in that when the time came I knew what I needed and what was going to work for me.
Fanuc is Fanuc, a teach pad with pages of drop down menu's, I have no doubt it can do anything the others can except...
What machine and what control?
none of the tool changes are using tool length comp - G43 H** , on my one machine this is fine, Siemens 828d but it has a proper restart procedure.
