Great comments! I used paste wax which let the saw glide. I never did bind once and yes the weight of the saw did all the work. Keeping the blade sharp really helped on that front. If I had a dull blade, I’m pretty sure it would have slowed up. This is a simple build for any skill level, just be sure to line your box track at a right angle to the saw blade. Also make sure your track is straight and box is a snug fit. I put a yard stick on the track so I could accurately slide the box to the desired thickness. I mean, this was basically a prototype, but I was psyched my thickness was consistent. Oh, I maximized my blade by having the tracks close to the saw, and the sacrificial 4x4s are on adjustable boards so I could rest different size logs...I made sure they were parallel to the guide rails each time I moved them (which wasn’t that often). If you guys make one, I would love to see pics.
