I had a Kreg miter gauge for my last table saw and eschewed a sled.
With a new saw coming, my thoughts are turning to sleds and miter gauges and I've just realized that I'm not sure of the use case for each.
At 1st glance, it seems as though a sled would lose accuracy relative to the cast iron top while gaining lateral and Fore & aft accuracy. That of course begs the question of sled design and build execution accuracy. Relative to a miter gauge, are we talking more than a .001 - .002 improvement over a miter gauge? I'm looking at the MicroJig Ultimate sled with a lot of interest - what do y'all think of it? Then there is the problem of where to put the darn thing when not in use.
In the other corner, we have the miter gauge. Quick to deploy and easier to store and uses the cast iron top as the flat surface. However, the piece is clamped with fingers and mine are not as strong as they have formerly been. That seems to be more important for actual miters rather than a simple 90° cut. Again, what is the difference between a miter gauge and a sled with clamps for a 90° cut?
To those willing to provide a quick education, my heartfelt thanks.
