This HDSLR Rig bridge clamp was intended for DIY builders in North America who have easier access to imperial measured stock materials and have some very basic tooling knowledge.
The block’s body is built from .75” solid aluminum square bar to accommodate .5” solid or stainless or aluminum rod.
Although made for .5” rod, the measurements will still accommodate 15mm standard should you decide to go that way. You may want to use 1” aluminum square bar for extra strength in this case.
I added the plans for this component first because all the other parts are built off it, or are variations of it.
I hope that these measurements are helpful. Build safe!
Minimal Materials and Tools
.75” aluminum square bar
.5” aluminum round bar (for light weight) or
.5” stainless round bar (for lateral strength)
#7 drill bit for .25” tapped holes
.25” NC 20 tap
.5” or 15mm drill bit for rails with pilot drills
2 X .75 NC 20 Bolts or Kip handles
Small band saw with metal blade or
chop saw with non-ferrous metal blade
These plans are a work in progress. As such you should use these plans at your own risk and verify measurements the independently. There are no guarantees to measurements or functionality of the part(s) described. I will not be held liable for any damages, loss or personal injury during the building of, or use of this design.
