Good ideas for infeed supports George. I have 3 of
these guys I use when needed for infeed/outfeed helpers. They suit my needs but can be a little of a pain on uneven floors like my shop/driveway.
Nathan, you're right about the downsides of a miter gauge. I have trouble with longer pieces using mine which is precisely what prompted me to finally make a shooting board. I'd disagree about the friction issue being a problem for miter gauges though. More surface area=more drag from friction. And unless your Dr. Who, your work has to be smaller than your sled 😉 But I agree that friction is a concern in general. I think in both cases, sled and miter gauge, the greatest source of friction is in the miter slot/runner. At least on my table saw. I wish all saw makers would standardize miter slots as dovetails. When I had
my sled, I put formica on the bottom side and that worked great.
If you go to my project on the bad place, you'll see I built it with two hardwood runners. I eventually replaced them with a single adjustable runner.
