Just love playing around and building everything I can. This one has full length 19" deep combs. About as large as you can get without losing a bunch of comb to heat.
An-Nahl, The bar length is a total of 20 inches. Taking into account the part that rests on the cleats, I'd say the comb is about 18 inches across.
Paul, Very important. It needs to be 1-3/8. Some will say smaller or larger depending on whether the bees are making brood or honey comb. I made all mine the same. You may get a little bending or wave on the edges, but if you keep on top of it, it is correctable. And call me Mike...
I should add for anyone building a TBH, that it may be best to keep the bar length for your TBH the same as a langsthroth bar. It will allow you you transfer the comb into standard equipment, or even sell to others (If they do the same). When they are all different "custom" build TBH's with varying bar lengths, you lose many possibilities and flexibility.
