I rip 2x4s at 1 1/4 inches. I get two TopBars from that that are 1 1/4 X 1 1/2 inch, which is perfect for the two sizes you need. Small for brood large for honey. Just turn them to the side you need. I also get a largish peice of scrap from the two cuts which I can use as emmergency topbars or as general scrap wood I use for other miscellaneous purposes. If you don't like the rounded edge, just make it 3 rips instead of two, but I like the rounded edge bars for the honey topbars and the squared edges for the brood nest. This lets teh bees pull air from back to front when they fanning for evaporation or heat management.
