I am doing a little study on foundation. I am modeling it in a CAD package and want to double check my research. When I have the results of this little study I will post them. Here are the questions for you foundation gurus.

1. What is the wall thickness (at its narrowest point) for comb? Does this thickness vary from small cell, standard worker, and drone foundation?

2. What is the spacing of the various kinds of cells? i.e. small cell=4.7cm/10cells, standard worker=5.4cm/10cells, drone=6.6cm/10cells and so on and so forth.

3. How deep is a typical cell in a ten-frame set up?

4. How many cells are on a medium foundation of small cell, standard worker cell, and drone cell?

"Each cell is less than 0.1 millimeters thick and maintains that thickness to within a tolerance of 0.002 millimeters"

I’ve only really tried to measure worker brood cells, but I don’t think they vary that much between the different kinds of cells.

>2. What is the spacing of the various kinds of cells? i.e. small cell=4.7cm/10cells, standard worker=5.4cm/10cells, drone=6.6cm/10cells and so on and so forth.

Spacing from center to center of the comb midrib? That is dependant on both the thickness of the comb (which is dependant on the diameter of the cell, see below) and the size of the bees, but it's safe enough to estimate that a beespace between combs will be 3/8" and the thickness is listed below. Basically natural sized worker comb is 31.75 average, but it varies. I've seen as small as 30mm and as large as 35, but it averages right around 31.75mm to 32mm.

This was brood comb:

Spacing of the cells themselves?

Standard varies a little but is all right around 5.4mm. Small cell foundation is 4.9mm. Natural sized worker cells run mostly from 5.1mm to 4.6mm. Natural drone comb runs from 6.0mm to 6.6mm. Drone foundation usually is about 6.6mm

There are pictures of measurments of various foundation and plastic here:

>3. How deep is a typical cell in a ten-frame set up?

A typical cell for a given diameter for brood comb is pretty consistent. A typical cell for honey storage varies greatly. The spacing of the frames may affect the size of the cells, but it’s the size of the cells that affects the depth of the cell.

http://www.beesource.com/pov/lusby/table.htm

A 5.5mm cell size (close to typical foundation) has a comb thickness (both sides) of 22.6mm (11.3mm per side). A 4.925mm (small cell) cell has a thickness of 21mm (10.5mm per side) and a cell with a diameter of 4.7mm (near the small end of natural sized cells) has a thickness of 20.20mm (10.1mm per side).

It depends on the diameter of the cell.

>4. How many cells are on a medium foundation of small cell, standard worker cell, and drone cell?

I don't have the numbers in front of me at the moment. I have them in a document at home. I’ll try to find it and post it.
