Staggered guide rollers are not a new idea, several of the old-time (80's or 90's?) 4x6's had it as a feature (Ridgid I think was one brand (as in the pipe wrenches).
I came at it from my obsession with square cutting.? You get best blade support and hence most accurate cutting on a normal saw with zero clearance between the rollers and the blade.? But the bearings just destroy themselves in short order because of swarf rolling through the zero gap, putting huge load spikes into them.
So I made completely new guide assemblies and drilled the guide brackets (that the rollers attach to) so the rollers are only 0.022"? apart (in line with the blade).? Both rollers are on concentric mounts, so there is no way to adjust them. The blade 'snakes' the extra 0.003" and is very rigidly held and absolutely square to the brackets.? Makes the blade a bit harder to put on as there are no pinch-rollers to hold it any more, but its ok. Finished making them a month or 2 back and haven't evaluated them fully yet, but early indications are good.??
I've not investigated it, but I think you'd be able to jigger the standard guide brackets by filling in the hole that mounts the outside side guide roller, by Loctiting?a bit of studding in place, or a rod in if its not threaded, and then redrilling, so the bearing mount is 4-6mm higher on the upper guide and same amount lower on the lower guide.? It doesn't need much.?
Its nice to have removed an adjustment point and improved rigidity, plus the side guide rollers should last indefinitely - jv
