I like your table top setup and I think I like the tool holder add on also.
I'm the guy who got Probotix to make the first extended Meteor machine a few years ago. I simply asked and they said no problem, it's only a few inches of bar.
The only down side to the larger work area is that you really need cross supports to keep the .75 inch MDF spoil board from sagging in the center of the table. The sag is significant in the center if your doing any detailed cutting because the heights will be different depending on which point of the table its cutting at. You need at least 1 cross support in the center but I'm guessing 2 of them spaced equally from the front and back bars would best.
So 4DThinker where exactly did you buy the extra bars from that I see in the pictures? I want to buy some also to add the cross supports so the center of the table does not sag anymore. Do you have a link for exactly what I need to purchase? That would be helpful. Also what parts did you by to attach the new bars to the current table? Like 90 degree corner joints?
I've been sing my machine pretty steady since I purchased it mainly for cutting parts for products I build, and most of those parts are wood & .187 inch G10 Fiberglass sheets. The machine has always worked without issues.
I did have some trouble with Dewalt 611 routers burning up while cutting .75 inch birch sheets with a 1/4 inch end mill. I think I killed 3 routers on that project. Good thing Lowes had a good return policy
Speaking of that extra space the new Nebula will give you.... Here is a sign I cut for my wife's friend. Its 36" round and it's the flower of life sign.
We just painted the front of .75 inch MDF and then cut it out. It came out fine, I cut it slow
