Test #3 Aid

Front

Theatrical flats

Back

• - easy to fly, light weight, traditionally constructed of 1x3 with muslin, built with keystones/corner blocks, built so the face of framing touches the facing material which is traditionally muslin

• - joints held together by gluing and securing corner blocks and keystones to the framing with staples, screws or nails

• - doors battened end to end joints

• - toggles typically 4'-0" on center

• - typically made with 1x3 framing

• - covered with only muslin

Front

Hollywood Flats

Back

-easier to stand & attach to one another

• - sturdy in large area with little support

• - constructed of 1x3 with lauan covering

• - end to face joints in framing

• - wood glue & 8d coated nails to fasten framing

• - edge of framing members touching lauan facing

• - lauan facing glued & stapled to framing

• - toggle typically placed 2'-0" on center

• - rails are at top/bottom framing member of a flat, stiles are long vertical framing members that sit within rails, toggles are internal framing members between the stiles, other factors is the cover

• - lauan facing on flat might be covered by muslin (this fabric hides seams)

• - sheet material is 4'-0" wide by 8'-0"

• - double toggle is where the sheet material meets up with another piece

Front

Grain direction of a corner block

Back

• - parallel to sides of the block

Front

Does grain direction matter when making corner blocks and keystones?

Back

• -grain direction of corner blocks and keystones runs perpendicular to the joint, makes it stronger

Front

Grain direction of keystone

Back

• - length of the arch

Front

Cut list (hollywood flat)

Back

• - 4'-0"x10'-0"

• - 2 rails 1x3 @ 4'-0"

• 2 stiles 1x3 @ 9'-10 1/2"

• 5 toggles 1x3 @ 3'-10 1/2"

• 1 - 1/4" lauan @ 4'-0"x8'-0"

• 1- 1/4" lauan @ 4-'0"x2'-0"

Front

Know the 3 parts of a stair unit

Back

• - tread (part you step on)

• - riser (facing to the step, helps support the tread)

• - carriage (part that supports the tread & riser)

Front

Cut list (theatrical flat)

Back

-4'-3"x11'-5" (actual width of face of the framing is essential)

• - 2 rails 1x3 @ 4'-3"

• - 2 stiles 1x3 @ 11'-0" ( height minus 2 rails)

• - 2 toggles 1x3 @ 3'-10" (width minus 2 stiles)

• - 4 1/4" plywood cornerblocks

• - 4 1/4" plywood keystones

• - 2 1/4" lauan @ 4'-0"x4"-3"

• - 1 1/4" lauan @ 3'-5"x4'-3"

• - 2 rails 1x3 @ 4'-3"

• - 2 stiles 1x3 @ 11'-0"

• - 2 toggles 1x3 @ 3'-10"

• - 4 1/4" ply cornerblocks

• - 4 1/4" ply keystones

• - 2-1/4" lauan @ 4'-0"x4'-3"

• - 1-1/4" lauan @ 3'-5"x4'-3"

• - 1- muslin cover @ 4'-9"x11'-11"

• - always remember that the lauan cover might need the be shorter for covering

Front

Know the differences between the 3 types of stair units

Back

• - cut carriage: typically cut out of 2x12, needs additional support to stand, either legs or mounted to the platform it rises to

• - closed carriage: treads supported by cleats mounted to the carriage, needs to be legged or mounted to platform for support

• - independent stair unit: a stand alone unit that needs no additional support, carriage is made from 3/4" plywood

Front

Platforms

Back

• - standard sheet material 4'-0" x 8'-0" drives our choice of modular platform size (variations are usually divisions f the 4'x8" sheet)

• - lids are usually made from 3/4" thick plywood

• - framing us usually 2x4

• - 2 rails 2x4 @ 4'-0"

• - 2 stiles 2x4 @ 7'-9"

• - 3 toggles 2x4 @ 3'-9"

• - 1-3/4" ply cover @ 4'-0"x8'-0"
