What should never be used to remove drill shavings?
I don't think there is a lot you cant use to remove drill shavings, but a vacuum is a good idea. Unless there are drill parts around or other items you don't want to suck up. Also a pan and brush works.

What are silver and deming drill bits?
They are considered to be all purpose drills, and are used wherever the maximum chuck capacity is 1/2". Often they are manufactured with one or more flats. They are also called S&D Drills, Blacksmith Drills or Prentice Drills (Canada). All Silver and Deming Drills are 6" overall length with 3" flute length.

Which drill bit do you use to make a hole in melamine plates?
A standard HSS drill bit will do it. Be sure to back it with a piece of wood, or it may crack.
What types of drill bit to be used for hole of 12mm dia in 12mm SS plate?
A standard HSS drill bit in 12mm is all that's needed.
Can I use SDS plus drill bits in a standard SDS power drill?
If the bit fits and locks into the chuck you can use it.
What is the purpose of a glue gun?
Glue guns are designed to heat up hot glue for craft projects. The glue gun warms up special glue sticks, and makes it easier to apply this glue to the right place in the projects.

Procedure of theodolite methods in setting out of stage?
Procedure:-
1) Let LOM is the horizontal angle to be measured as shown in fig. O is the station point
fixed on the ground by a peg. Set up the theodolite over the peg 'o' and level it
accurately.
2) Set the horizontal graduated circle vernier A to read zero or 360° by upper clamp
screw and slow motion screw. Clamp the telescope to bisect the bottom shoe of the
flag fixed at point 'L' and tighten the lower clamp. Exactly intersect the centre of the bottom shoe by means of lower slow motion screw. Check that the face of the
theodolite should be left and the telescope in normal position.
3) Check the reading of the vernier A to see that no slip has occurred .Also see that the
plate levels are in the centre of their run. Read the vernier B also.
4) Release the upper clamp screw and turn the theodolite clockwise. Biset the flag
bottom shoe fixed at point M by a telescope. Tighten the upper clamp screw and
bisect the shoe exactly by means of upper slow motion screw.
5) Note the reading on both the vernier to get the approximate value of the angle LOM.
6) Release the lower clamp screw and rotate the theodolite anticlockwise ai azimuth.
Bisect again the bottom shoe of the flag at 'L' and tighten the lower clamp screw. By
means of slow motion screw bisect exactly the centre of the shoe.
7) Release now the upper clamp screw and rotate the theodolite clockwise. Bisect the
bottom shoe of the flag fixed at M and tighten the upper clamp screw. By means of
slow motion screw bisect exactly the centre of the shoe. The vernier readings will bw
now twice the of the angles.
8) Repeat the process until the angle is repeated the required number of times (usually
3). Add 360° for every complete revaluation to the final reading and divided the total
angle by number of repetitions to get the value of angle LOM.
9) Change the face of the theodolite the telescope will now be inverted. Rrpeat the
whole process exactly in the above manner and obtain value of angle LOM.
10)The average horizontal angle is then obtained by taking the average of the
two angles obtained with face left and face right.
11)Usually three repetitions face left and three with face right should be taken and the
mean angle should be calculated.
