24' Diameter Dome Assemblage
Fabricate 24' Diameter Dome
 | Cutting truss boards |
The boards are accurately cut using two power miter saws bolted to runners clamped to a rail constructed from 2 parallel 2x4s.
 | Drill guide used in drilling connecting member |
A drill jig combined with a TECH Craft drill guide is used to accuratedly drill the connecting members.
 | A pattern panel is used to create panels |
Two different precisely constructed pattern panels with side cleats are used in constructed the subsequent panels. Ten equal lateral panels and thirty pentagon panels.
 | Boards being drilled to make wedge connectors |
The scrap lumber from cutting panel boards is cut in multiples of 4" lengths. These short pieces are then drilled for 7/16" bolt holes on 4" centers, starting 2" from the end.
 | Ripping the predrilled Wedge connector boards |
The short predrilled wedge boards are run through cutting guides attached to a table saw. The saw blade is tilted to the appropriate angle, and the boards are run through twice, switching sides on each pass.
 | Cut predrilled wedge board in 4 inch increments |
The predilled wedge boards are cut in 4" increments.
 | A Pattern is used to cut the plywood sheathing |
A pattern in combination with a power saw is used to cut the plywood sheathing. Holes in the pattern are used to mark the sheathing for fastener placement.
 | Cleats are used to position sheathing to panels |
Temporary placement cleats are used on the sides of the panels when accurately positioning the sheathing. If elastomeric is going to be used as a roofing, then any holes or protrusions need to be filled and sanded before priming and painting.
 | Attach wedge connectors |
The wedge connectors must be attached prior to assembly when presheathing the panels. It is also advisable to do the same when using unsheathed panels. The wedges should only be attached to either the right or left hand side of each panel, and can be attached using 18 x 1-1/4" wire nails.
