Small quantities of 1/4", 1/2" and 3/4" plywood
Office chair with wheels-got free from a used office furniture supply store
1/2" thin wall electric conduit-10 ' section -some have a line up the side and it helps when drilling holes
3/4" thin wall electric conduit-same as above
1 ea 12" truss strap 1 1/4" wide-cut, drilled and bent into 2 U shaped brackets
1 ea 18" truss strap 1 1/2" wide-drilled and bent into moving handle
misc bolts, fender washers, nuts, fixture knobs and 1 handle - 3/16" and 1/4"
2 ea lag bolts about 3" long to connect 19" box and the other wood assembled section
Remove chair seat and throw it away
Cut plywood and make 19" high box, width and depth determined by the remaining base on the chair
Cut the plywood pieces, glue up and crown nail together-see drawing #1 for sequence- of the top section of assembly
Holes in side of largest plywood pieces are for pins if counter weight(see below) is not sufficient
Use lag bolts to join the top section to the box and box can be attached to chair with 1/4" carriage bolts/nuts
cut 1/2" thin wall conduit 70" long and use pipe bender to bend end about 1" off center - see drawing for hole drilling
cut 3/4" thin wall conduit 87" long and see drawing for hole drilling
12" truss strap- cut, bend and drill 2 U shaped brackets to be attached to the camera platform and then ends of conduit
18" truss strap-drill and bend as per drawing B - attach handle to top
will have to turn and drill round spacers, cut at an angle in handle assembly-see photos
You will need an approx. 8# weight as a counter weight on the short end of the 3/4" conduit- drill a hole and use a pin to keep in place
