STATE BOAED OF AGRICULTURE. 



Fig. 5. — Self-Spacing Frame. 



These frames have grooves in the top bar for fixing the comb 

 foundation and holes in the end bars for wires. Fine tinned wire 

 (No. 30 gage) is threaded through these holes, stretched tight and 

 fastened. To these the sheets of foundation are fastened by em- 

 bedding the wires in the wax. "\^arious devices are sold for the pur- 

 pose, but any narrow piece of iron with a shallow notch filed in the 

 end will do. This is kept warm over an oil stove or lamp and is used 

 by drawing the notch along the wire, bearing on just enough to bed 

 the wire without cutting through the sheet of wax. In doing this 

 work the frame is slipped over a board on which the foundation is 

 laid.
