Are the sliding fence SME supposed to droop a little?

I would say no bill they don't on mine. well one has a little because I need to trim some uhmw away from an edge.

It looks like the shot side is down a bit or maybe its the picture you need to make sure the centre been is very level with the cut line.

If you look at the real ez-1 there are levelers for the foam beam.

Bill,

Are the top edges of the frame SSMEs in the same plane as the shelf on the side of the cutting beam? If they are, then the SMEs should form a plane with the top of the cutting beam. Could it be that the plastic that the SMEs are screwed to needs to be shaved to allow the SME to sit on the shelf of the cutting beam?

Bill I see that the foam beam is not level with the end ssme and thats what the levelers are for. Looks like you need to go down a fare bit.
In any case it looks like the foam beam needs to be looked at Dino has a video on the EZ-1 setup.

If you look at the second photo it appears that the foam SSME is about 1/2 to a 1/3" too high at the FRONT SME.

I agree with Mel. When I added the foam beam to my DIY PBB I had to cut a notch out of the underside of the beam to get it to sit flush. See photo #2 in post #11 (http://tracksawforum.com/showthread.php?t=837&page=2).

Bill,

Does this help seeing the relationship?

The foam bar looks like it has a notch cut out of the end on Tom's table.

The sketchup drawing doesn't help. Too many other parts in the way to see how the foam rail aligns with the end extrusion.

I'm now guessing that the portion of the foam bar (where it becomes a B2B instead of and SME) is at a level with the top edge of the end extrusion.

I enclosed 3 pictures of two SSME. Please tell me which one is the correct alignment.

Bill,
The orientation in sample #2 would be correct. The top of front SSME would be even with the top of the SME portion of the foam beam. My photo and Dik's drawing show the foam beam and the front SSME at the same level. The difference is that I chose to have the beam go to the front of the front SSME (thus the need to notch the underside of the beam) whereas Dik in his drawing chose to have the end of the foam beam even with the back face of the front SSME. Did I explain that okay? I know what I am trying to say

Joe

Bill,

I think Joe and I are talking about the same picture, but the picture ending in ..009 is the correct relationship. The SMEs should rest on top of the edge of the frame SSMEs and on the ledge of the foam beam so that the top of the foam beam and the SMEs are in a single plane which is the top of the bench.
