To get the length ofjack rafter take your square and measurefrom 10 to 12 and you will find it to beabout 15 3-16 inches, which means thatto set them on 12-inch centers cut eachset of them 15 3-16 inches shorter and fortwo feet centers cut them twice 30% inchesshorter each time. To get side bevel oftop cut off jack, take length of commonrafter on blade and run on tongue cut onblade; in this case they would cut 10 and13. In getting cuts for hip or valley al-ways use 17 on blade and rise on tongue. To determine the proportion a roof risesto its width always count from 24, as 12. part. It is all right for common raftersand is good for hip rafters only on halfpitch. I am giving you herewith a method ofroof framing that will work on a roof ofany number of inches pitch to the foot,which is very simple and easy to remem-ber, and one that I invariably use. and 24 are whole pitch, therefore 12 and12 are half pitch (24-7-12=2), 8 and 12are one-third pitch (24-J-8=3) and 12 and 6are one-quarter pitch (24-=-6=4).Fraternall} yours, C.
