[woodknots]

I use a push block to keep pieces square and steady when needed. Like Marc Summerfeld does in some of his videos. If I need to I drill a hole in the push block big enough to get the jaw of an F clamp into. Cost= $0 because I use scrap that I would have burned anyway, plus the push block gives blow out protection at the end of the cut.

Same here Charles - I attached an old push block to a piece of scrap wood - when the edge gets chewed up, I just replace the wood.
