Re: Ideal Top Bar width?
If you used 1 1/2" bars in the brood nest, and your bees built straight comb without joining it to an adjacent bar, then you may be over the hump. You can add new bars to the brood nest between existing straight bars,, and the odds are good that new bars will also get built straight.
As it is the honey bars that will get rebuilt after a harvest, and those are suggested at 1 1/2 inches, you should be OK.
