You are amazing Thanks for helping out and thanks you for sharing your knowledge with me and everyone else here.
I still have alot of flex in the middle of my QCW, not sure how to solve this issue.
Not even leaning on it. Like touching it with my pinky and pressing down will move the table by about .010".
while everyone is complaining about the frame wobble. the machine mounted to the frame wobbles at the exact same rate so therefore there is not issue. the waste board, frame and cnc are all one solid mass so the bit and the workpiece are both moving together.
FWIW, the leg bracing kit for the QWC Foreman table made a HUGE difference in stability of the table. Before when running a project with lots of lettering with a V bit the table would shake like crazy from all the rapid moves. Now, it is rock solid when doing the same kind of job.
I’m satisfied with the stability of the QCW and legs as sturdy doesn’t even do it justice to describe it. However, I’m using only one 3/4" thickness in the slats (opting for a second layer for the actual spoil board), and during tramming noticed there appeared to be a small amount of deflection if I touched the surface while taking measurements.
I only got to dial it in just before heading out of state for the week, so will have to revisit when I return. In the mean time I’m wondering if anyone else noticed the effect themselves?
I can’t speculate what I’m seeing and why yet but am thinking the second layer will make it all go away.
looking forward to your response and evaluation Phil.

hey Dave good to hear about the newer QWC HD ,hoping its stable enough, let us know how it goes?

I finished some deflection measurements I had promised. This is on a Gen2 Foreman heavy duty QCW fixed stand. I used the same digital indicator and spindle bar used for tramming with measurements taken at the exact center of the work area. I don’t have my upper layer waste board completed yet so measurements are on the 3/4 MDF machine base (probably the same as most others have for their waste board).
With a piece of Walnut that measured 16x6x1.5" with a weight of 57.65oz it yielded 0.03mm deflection (with the piece stood up immediately behind the gauge).
With a piece of Limba that measured 21x12x1.5" and weighing 11.9lb it yielded 0.07mm deflection.
I suspect that when the second layer (waste board) is mounted this deflection will be even smaller because of the added stiffness it provides.
Generally, in the world of wood working, this deflection will mean nothing. But it might be possible that some detailed carving (like vcarve inlays in denser material stock) could be affected in some way.
Time will tell if I can detect any real effects though.
