[zipper1022]

hey i am going to build something like this...

HAGUE D8 ladder dolly

except im using this head

http://www.bhphotovideo.com/c/product/494457-REG/Davis_Sanford_V12_V12_Fluid_Head.html

and i plan on making the wheels more like this so i can run it on a round track or on smooth ground

has anyone make anythign like this one, i want something small and low to the ground, the fluid head is cheap i know but im just making this as a tester to see what i can get out of it and i want it to be very light so i can carry it everyday with me


(im an extreme sports ...bmx... videographer)

im going to build it primarily out of pvc with small angle iron for the wheel sections and the teipod head will be reaised slightly so its not too low

anyfeedback?
comments?
ideas?
examples?

those are both awesome examples but i hope to make mine a little wider so it can fit around my camera bag and be wasily carried, and im making it out of pvc to save weight, the tripod head will be the heaviest piece at 2 lbs
