These things are pricey, with even the cheaper folding ones starting at
+/- US$ 150, and many of them seem to be a bit fussy to install on different saws.Having moved and reconfigured the shop, I needed something quick to get a job done, so here's my minimalist version, made from scraps and one ripped in half tubafour, that uses French cleats to attach to my Unisaw:
Although it works fine just as it is, eventually one would want to add aprons to stiffen the top and route dadoes for the miter gauge slide, etc.
Since it did the intended job admirably and with spades, I'll probably keep it and spiff it up a bit.
(And no, C-Less, Festool does not make one!)
