THEA 103 1st Edition Lecture 6 Outline of Last Lecture I. Medieval TheatreII. Renaissance TheatreOutline of Current Lecture I. Screws/BoltsII. HingesIII. Locks and RiggingCurrent LectureI. Screws/Boltsa. Screw: Is measured from top of shank to point. Has threading. Will lie flush. Is tightened by torqueing the SHANK.i. Philip’s Head: star shape, Flat Head: one line, Roberston/hex-head: pentagon or square shaped keyb. Describe a screw using length (from top to tip), gauge (fatness, width ex. 6 gauge or 8 gauge) and shank diameter. Another measurement considered is the distance between threading.c. Example of describing a screw: “#6 (gauge) 3 in (length) Philips’s (head type)d. Bolt: No pointy end, made to go through a drilled hole. Uses nut and washer to secure. Is tightened by torqueing the NUT.ii. Stoke bolt/machine screw: requires screw driver and wrenchiii. Hex-head bolt/Cap bolt:iv. Machine Bolt: dome head, won’t be flush. Length measured from BOTTOM of shank to tipv. Lag screw or lag bolt: (Not a true screw or bolt, but a hybrid): meant to gointo a material, used when you can’t get to other side of a material. Is POINTY, meant to PIERCE.vi. Carriage Bolt: Requires HAMMER to install. Needs wrench to fix nut. Unusual shank shape that gets hammered in to secure things. Measured by diameter of shank. Drill a hole as big as the shaft before installing.These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.vii. U-Bolt: No pointy parts, shaped like a U. Has a plate that acts as a washer.Used to hang thingsviii. Forged eye-bolt: stronger eye-bolt. All one piece. Used to hang rope, chain. Can hold a lot of weight.ix. Standard eye-bolt: Less safe, bent hook, not as strong.x. Stage-screw: MISNOMER, actually a bolt. Used for quick changes, has a lot of torque. Triangle shaped head.II. Hingesa. Piano Hinge: Long thing hinge, used on pianos. Lots of tiny screw holes. Double-acting hinges can swing both ways.b. Strap Hinge: Very strong. Two triangles joined by a pivot. Used for barn doorsc. Butt Hinge: Slightly smaller than back flap. Rectangular with 2 screw holes.d. Back flap Hinge: Most common. Can go both ways, double-acting. 3 screw holes. Can have removable pin, can pull apart for changes. Made for surface mounting.III. Locks and Rigginga. Wagon Brake: Used to stop wagon with casters on it. 2 kinds.b. Caster: Wheel. Think, shopping cart. Can be fixed or swivel. Need to turn on a radius in acircle? Use dumb castor and an axis point.c. Coffin Lock: Can lock and unlock quickly with key. Can be pulled apart. Square with hole in middle. Used for things like flooring.d. Roto Lock: Loop and saddle and bolt. Used to get 2 pipes at 90 degrees. e. Cheeseburger/Cheeseborough: 2nd way to get 2 pipes at 90 degrees.f. Speed Rail/Key clamp: Fixed, has holes for allen screws. Used to hold 2 pipes at 90 degrees.g. Flange: Circular or square. Used to secure piping to a flat surface. Pipe fitting.h. Turn Buckle: Used for rigging. Will only be as strong as its weakest link. Can make very small adjustments to height by turning.i. Chain linkj. Shackle: Uses bell and pink. Aircraft cable: Uses nicopress sleeve to synch wires cable together. This makes connection permanent. Has “Thimble,” a loop at one
