Right Triangles

Given any 2 Parts of a right triangle, be able to complete the whole triangle instantly... (run, rise, angle, pitch, tangent or slope)
-------------------------------------------------------------
Oblique Triangles

Given 2 angles and one side or 2 sides and 1 angle. You have your angle instantly.

Need the Area??? The Jobber 6 can give you that too.


Bolt Circles can be solved in seconds. Know the diameter? Know the bolt pattern? The Jobber 6 will give you everything you need to know to complete it

If you know any 2 parts of a circle, let the Jobber 6 will tell you all the rest.

Need the area? Once again the Jobber 6 can give it.

Here is an example of how the Jobber 6 could solve a more complex circle using the segmented rise function.

All that is known is the radius (12'-8 1/4") and the cord (23'-6"). Default spacing was set to 1'-10". with special spacing changed 2'-4" and 2'-1".

With the Jobber 6, the everything you need to know about this circle can be know in seconds.


With the rake-up function on the Jobber 6, you can solve the increasing length for studs in a raked wall or gable end. Using the stored values of the run, rise and slope, you can then set the default spacing for each.

The example to the right, the default spacing is set to 1'-4". But at any time, a special spacing can be added. In this case, special spacing was set at 1'-6" and also 2'-6". Once this special spacing has been done, the default spacing will automatically go back to the 1'-4", the spacing you already set at the beginning.

The rake-down function works in a very similair way as the
rake-up function with the exception it starts with the high side of the triangle and works it's way down.


Simple to the most complex roof systems are no match for the Jobber 6.

In this example, we have a 5 1/2 to 12 pitch and a 24'-0" span. In a matter of moments, we can find the common rafter length, hip pitch, hip length and the jack lengths just by the touch of a few buttons.

If you are working with a hip roof, you can figure your Jack rafter lengths (see picture below). Set your default spacing to whatever you desire and off you go! It really is that easy.


Stairs have you baffled?

Do you have the floor to floor height, the maximum riser height, the length of the tread? If you do, you have everything you need in order to solve this entire stair design.

The Jobber 6 will let you know every detail of the stairs based on the information you provide.

It is that easy!! And with the 0 to 15 keypad, your number of keystrokes is drastically reduced and time spent is easily cut in half.


Find degrees for miter cuts and miter pitch in just a four steps.

Figuring cubic yards of contrete is something every builder and contractor has to do. One of the new features on the Jobber 6 is a cubic yard button.

Figure anything from footers to clabs to concrete walls. How much concrete do you need? Don't under estimate or over estimate. Hit a few buttons on your Jobber 6 and now exactly what it will take.

Pouring an odd shaped slab? How many yards of concrete are required?

Seem Complicated? Not for the Jobber 6. Have your answer in less than a minute!


Need to square up a floor? A wall? If you know any 2 parts, the run, rise, or slope, the Jobber 6 will give you the missing part of the puzzle.
