If it did, however, I would add 2 more bolts and attach it to both the top and bottom slot and it would definitely be dead on rock solid. I may do that anyway.

If I had ti to do over, I might have done the top cross ones a little differently, I would not have cut two slots in the top so quickly. I would have put one in the top and one underneath. I am still trying to come up with a 2-way sliding cradle, and debating cutting an additional slot in the bottom anyway.For the moment, I need to put them where I want them and slap a clamp on them if I don't want them to move.

very good. glad to hear it's solid.

Do you really need 4 sliding crosses on top? maybe just three? one for a fence, two to capture the wood. I can see how just two would work as well. since you seem to have multiple t-tracks in one "extrusion"

Are those two pieces of vertical ply acting as your fence? I noticed that the fence works better on the opposite end of the Bridge handle, because the downward-forward motion of the bridge pushes the material forward. Unless I have my bridge configured wrong? I'm starting to think i'd prefer an up and down hinge style rather than a handle so my wood stops moving. Not a problem on the EZ-one with the 6-way stop setup, but otherwise i find myself needing to readjust against the fence often.

Otherwise, go solid top (double 3/4" MDF) and eliminate the sliders completely? just need to embed some cheap t-track. That thing will be solid as a rock.

If you do solid top, you can even make festool style dog holes. Another member here, Mike, gave me the idea. There's a jig i had 3dprinted online for $11.50 shipped. I'll make a post about it once it arrives.

All budget friendly. I like it very much!
