Our blade guides are very simple but sturdy devices for use only in tight radius sculpting. Their main function is to serve as a visual reference for the operator that tells him/her when the blade is getting off its nominal center. We know from experience what happens when the blade gets wrapped around a .5" radius roller guide (even briefly) at 1725 RPM; you start breaking blade welds (metal fatigue).
They're spaced far enough apart to see a little gap on each side of the blade. If you use blade guides to bully the blade through a log by over-driving the feed, you're just going to end up with squirrelly cuts and wasted wood.
Check out the video (#1 below) of the Mesquite log we ripped without any blade guides if you doubt.
But then, if you really want to cut tight corners, these are the blade guides you want to use. To see 1/2" radius turns, see videos #2 & #3 below.
