It depends on what you want to measout. For less than a 90° angle, use the numbers below 90°. For angles more that 90° use the numbers above 90°. A flat surface has an angle of 180°. At any given point. If you make a point somewhere in the surface, and raise an end 1°, The angle @ the pivot point is 179°.

All purpose presentation easel a DIY project


You never know when you are going to need or want an easel to show off your art work, maybe your kids want to finger paint who knows they could be the next Van Gogh. Building a display easel is very simple and can be done in just a few hours.

You want to start with two pieces of wood cut to 2x82" these pieces will form the front legs of the easel. Using a table saw cut the tops of the wood to a 15* angle. Take a measuring tape and measure 78" from the bottom of the wood (up to the angle cut) mark this spot on both pieces.
Using a drill, drill a 3/8" hole through the widest side of the angle as a right angle to the cut. Repeat for the second front leg.

To make the back leg cut a piece of wood down to 2x81" long, using your drill, drill two 3/8" holes in the widest side of the wood. One hole should be 39" from the bottom of the wood and the second at 74" from the bottom.

Your art work needs something to sit on so to make the cross bar cut a piece of wood down to 2x47".

Now you are ready to assemble your easel. Take the front and back legs and lay them on the floor next to each other with the back leg in the middle. Rotate the front legs to the angle is facing the back leg and line up the holes. Slide a bolt into the hole and place a washer and a nut on the end, keeping it loose enough to adjust the angle. Stand up the easel and spread the from legs so that they are 45" away from the back leg. Tighten the bolt and you have the angle right and lay it back down.

To attach the cross bar, measure 38" up from the bottoms of the front legs find the center and drill a 3/8" hole in each and bolt the cross bar to the legs. To keep the legs from spreading too far you can attach a chain between the cross bar and the back leg. To do this you thread the chain through the hole in the back leg and tie it off. Attach an eye screw to the cross bar and loop the chain through it to keep limit how far the legs can spread to the angle that you want to work or display at.

My Bosch DWM 40L angle finder has locked itself on 888.8 and I can not swithch the machine off, even when I put in new batterie it does not correct itself, please can you help.


Open the the moveable arm and make it straight (180 degrees) or in line with the other.Take the screw off of the black cover at the elbow (1 screw). Lift from the round part and lift off. Then loosen the two screw just inside the cover. This will allow the flywheel to spin and you should now get a read out. If the flywheel does not spin then you need to replace that piece. Gently tighten the two screws and put the cover back on. Hope this helps!

There is an electronic component that is defective and it draws a lot of current (more than the normal rating) this makes the batteries over heat, if it's new ask for replacement of the tool.

It is a device used in measuring and sometimes drawing angles?based on trigonometry


Could you mean a sextant? I found other tools of measuring angles at a
distance before I reread your question and noticed it was under
science and astronomy. Most of the following tools are used to measure
angles of stars, planets and locations.


Sextant
=======
"A sextant is a measuring instrument used to measure the angle of
elevation of a celestial object above the horizon. Making this
measurement is known as sighting the object or taking a sight. The
angle, and the time when it was measured, are used to calculate a
position line on a nautical or aeronautical chart. A common use of the
sextant is to sight the sun at noon to find one's latitude. See
celestial navigation for more discussion.

The scale of a sextant has a length of 1/6 of a full circle; 60°,
hence the sextant's name. An octant is a similar device with a shorter
scale, 1/8 of a circle; 45°, which was in use until 1767 when it was
quickly replaced by the sextant. In 1767 the first edition of the
nautical almanac tabulated lunar distances, enabling navigators to
find the current time from the angle between the sun and the moon.
This angle is however sometimes larger than 90°, and thus not possible
to measure with an octant."
http://en.wikipedia.org/wiki/Sextant

"Practical celestial navigation usually requires a chronometer to
measure time, a sextant to measure the angles, an almanac giving
angular schedules of celestial objects and a set of sight reduction
tables to help perform the math. With sight reduction tables, the only
math required is addition and subtraction. Most people can master the
procedure after a day or two of instruction and practice."

An angle gauge?
===============
"The gauge is used to tally trees in variable area plot sampling. The
variable plot method is generally faster than fixed area plot
sampling. The gauge usually has basal area per acre factors (BAF) of
5 to 40. The average diameter of the trees to be sampled is what
determines which BAF to use. The angle gauge comes in several shapes
and serves the same purpose as a cruising prism (see cruising prism
below). 2004 price range: $10-$33."
http://ext.nrs.wsu.edu/handtools/tools/measurements/#clin



A clinometer?
=============
"Optical Reading Clinometer
Model No. PM-5/360 PC
Measures:Altitude angle/Percent slope
Heavy-duty clinometer for measuring vertical angles. Clinometer has
two scales: angle in degrees above or below horizontally level or
percent slope. Sighting allows user to simultaneously view object and
read slope."
http://www.pge.com/003_save_energy/003c_edu_train/pec/toolbox/tll/tool_catalog/misc_instru.shtml

"Measuring with a Clinometer

A clinometer is a tool that can help you to measure the angular height
of the Moon more accurately than with your fists."
http://www.learner.org/channel/workshops/lala/moonjactivities.html


A protractor?
=============
"Use tape to hinge two rulers together end to end at a 90
degree angle. Hold one ruler so that it points straight out
to the horizon and the other one points to the straight up
to the zenith. Tape a protractor to the rulers so that the
base is on the horizon line and the zenith line cuts the 90
degree mark.

To determine the altitude of the North Star where you live,
hold the rulers horizontally at eye level. Look at the North
Star and move the ruler to point at it.

The number of degrees or altitude of the North Star can be
read on the protractor."
http://spikesworld.spike-jamie.com/science/astronomy/c421-03.html


A transit?
==========
"These units are for the serious builder or contractor who requires
greater accuracy. These instruments are designed with a heavy-duty
dome shaped head that holds a double ball bearing center, giving the
user 5 minute readouts. Model 300B has a 1° vertical arc and two
leveling vials. Units use a 3-1/2 x 8 thread."
http://historywired.si.edu/object.cfm?ID=186

http://www.contractor-books.com/CB/Optical_Levels/Optical_Levels.htm?source=google


"Set up for the class five angle measuring exercises. Get each
participant to measure each angle. Rule out any clearly wrong
measurments; average the remainder. Now score each participant on how
little his/ her readings vary from the class's average.

An alternative test for your transit is to go to a large field. Along
one edge, mark perhaps 5 locations all in a straight line, perhaps 50
feet apart. (Use a longer distance if you can measure it accurately,
and space allows. (You can see they are in line by looking along it!)
About 150 feet from the baseline, at a point perpendicular to it's
middle, stick a pole in the ground. (The location does not have to be
precise.) Now measure angles between the baseline and the pole at each
of your locations. Next, prepare a map of what you have measured.
Start by drawing a line on a piece of paper. Mark 5 evenly spaced
points along it. Draw the angles you recorded. The lines going away
from the baseline should all met at one point if your readings are
accurate.

Remember: Any measuring device must be able to return the same reading
every time it measures the same angle, weight, length, etc. It must
give the answer in usable units.

With the transit, a major element in achieving success will be your
skill in devising something that will allow you to point directly at
the distant objects which define the direction of the two arms of the
angle.

How you read off how far around your pointer has swung will be another
critical area."

How do you find an angle measure for the angles XYZ if it looks like it's 63 degrees?


Place you protractor over the angle to be measured. Make certain the centre line is aligned with the apes (point) of the angle and one arm (of the angle) is aligned with the protractor's bottom edge. You can now read off the size of the angle by noting the position of the other arm under the protractor's degree scale.

How to build a wooden pyramid frame for school children, 2metres on each length of base.


cut 4 pieces of 2x2 to1.5 inches short of 2 metres. lay them out end to end to form a two metre box. it can only work one way. then take string from corner to corner to find the center, making a crosshair. then stand a level rod at the centre to the desired height and fasten equal length lines from each corner to the peak. using a compound mitre saw, place an angle finder at the bottom and top corners to give you the angle to cut your piece with the saw set at 45 degrees, to give you your compound miter for the top. just set the saw blade to line up with the angle finder to get the bottom cut. the length of your "tight" string line frome corner to peak is your length of "hip" piece

Skil 2100daf angle finder


I was trying to reset the zero on my angle finder. It's a Powerfist Digital Angle Finder, the same as the Skil 2100.

After turning the unit on, if I press the Miter and Hold button together and hold them, the unit goes into 'calibration' mode. (The display flashes 0.0). If you do nothing, it will always stay in this mode forever after that.

You can then reset your unit - it takes time however and patience.

With the aid of a large protractor, draw angles on a large sheet of paper (I used a couple of 11 X 17" pages) from 0 degrees all the way up to 220 degrees.

Turn on your angle finder and make sure the numbers are flashing 0.0. This will be your 0 degree reading. Hold the finder closed and press the Hold button once.

The display will now read 10 degrees. Open up the finder until it matches your 10 degree marks on your paper and press the Hold button again.

The display will now read 20 degrees. Open up the finder until it matches your 20 degree marks and press the Hold button again.

Continue setting your angles in this fashion up 'til you reach 220 degrees. The next button press will close the calibration cycle and the numbers will stop flashing.

Your unit is re-calibrated. Now, if it's off - you've only yourself to blame.

Good luck!
