Unlike a tap, a thread mill has a smaller diameter than the thread size being produced because the mill must be able to enter into the drilled hole and interpolate. Thread milling provides excellent control of the thread's major diameter because it can be controlled using the machine's cutter compensation. Understanding Thread Mills

5. Sizing the gutter outlet is a two-stage operation. The first step consists of choosing the downspout outlets required for the given peak flow. The second step consists of choosing a leader pipe for the peak flow or combination of peak flows. Keep in mind the following when sizing downspout outlets for different sizes of roof gutter.

Since we're working in Millirads, and we want to find the Radius, we need to start by multiplying our Target size by 1000 which will give us the total of 5 radians at this distance. But we only want to know the distance of 1 so we divide that total by the number of Mils we read. (Tz * 1000) / 5 = Distance to Target

Everything must have perspective, a point of view, to be communicated. To communicate the three spatial dimensions, we use the X,Y, Z coordinates. These denote height, width and depth. In referring to machinery we use the same X,Y, Z denotations, but we give them different values or meanings. To make it even more interesting, there…

There are 21,600 MOA in a circle, so a little quick division determines there are 3.4377 MOA per mil. At 100 yards, 3.4377 MOA equals 3.599 inches (3.4377 x 1.047). Rounded up, one mil equals 3.6 inches at 100 yards. • To convert MILs to MOA = MULTIPLY BY 3.5 (The precise math is Mils x 3.438 = MOA)
