Wood beam

Which is it? 3/4 ton or 1200lbs?

With the beam laid horizontal, and then oriented with the thick edge vertical, is the hole vertical or horizontal?

any beam be it wood or steel would be placed the "hard" way......I knew someone would ask that and thats why I stated the 3/4 hole is bored through the 6 inch diameter
1500 is the safe factor as it gives me a little leeway, 1200 is around the weight dry/ no battery/ radiator empty

No. For example, a header for a door or window opening of 8’ (less of a point load) would be 2-2x10’s. Your single beam is actually weaker than 2 pieces fastened together and will deflect or fail.

Thanks, I had my doubts and its why I asked
I had 600 on it many times and there was never the slightest deflection but doubling that weight I was skeptical
