I cleaned up the table with some Scotch-Brite on an orbital sander. My shop is heated and we don't have very much humidity in Boise, I just wipe it with an oily rag and it stays in pretty good shape.
As you can see I copied the vise design from the one on my Ellis saw. I picked up the Heinrich fixture locks used, at reasonable cost from a local used machinery dealer. eBay might be a good place to look; they are close to $100 new. I made all the rest and probably still have the CAD files if that would help. The two piece fence is bolted to the back edge of the table and is easy to remove if more space is needed.
I originally only made one clamp but quickly decided how much more useful two of them would be, so I made the second one. I can get a 6" wide piece in the saw using the front set of holes, any wider and the clamps are easily moved to the rear set of holes.
The saw works so well I haven't used the Ellis horizontal in years; if I did more fabrication that may be a different story. I do mostly machine work, it is very handy to be able to walk up to the saw set the stop, clamp the work, start the cut and walk away. This also makes repetitive cuts easy, once set up you clamp the stock then move the left stop out of the way. because the right hand stop is still clamped tight all you need to do for the next parts is slide the left stop back over, lock it in place and slide the stock over for the next cut.
