Basic Leveling Tools M.S.Martin Sept M.S.Martin Sept. 2005
Hydrostatic Level Consisting of clear tube and working on the principle that water finds its own level. It’s critical that there are no air bubbles in the line.
Boning Rods T-shaped timber, used in sets of three to achieve a level line by sighting along them. Sometimes used for trench bases. Look at larger picture on next slide.
Spirit Level All Carpenters have one in their tool box. Can be used for plumb and level lines. It can also be used in set-out work. See next slide for an example of this.
Automatic Level / Dumpy Level Base Plate Horizontal Circle Eye Piece Circular Bubble Sighting Pointer Objective Lens Focusing Knob Fine Adjustment Foot Screw
Laser Level Used similarly to a Dumpy level. But, where a dumpy has to have two people to use it, one for the staff. A laser can be used with only one person.

S.H.H.S Building Construction. Levelling is the process by which differences in height between two or more points can be determined. Leveling is a branch.

Light Microscope Eyepiece Contains a magnifying lens that you look through.
Microscope The Pieces and Parts. Body Tube #1 in picture Allows light from objectives to pass upward to form first image.
Microscope Notes. Eye Piece Also called the Ocular The part of the microscope you look through to see an image. The eye piece magnifies what you are.
MICROSCOPES. Microscope Parts: How to focus your microscope… Use COARSE focus 1st. Coarse focus - rough focus, larger knob. Use FINE focus 2nd. Fine focus.
Preparing a slide Before adding the sample, clean the slide with ethanol and cotton wool. Hold at a 45° angle Lower slowly to avoid forming air bubbles.
