New Crane!!!

Hey!

The crane is complete. Well, almost; it just needs powdercoating.

Check out some pics:

so I finally had the chance to hook up the camera and the monitor, and everything is working great except for one thing. When you use the manual tilt, it seems really jerky. I have come to the conclusion that it is the point where the camera sled meets the main arm. There is a lot of surface area for rubbing, and I have no idea what to do! Help me!
 
hey man, like the crane, looks nice, good job fabricating. From an engineering point of view, this thing looks like it could hold a horse on a good tripod that is.

friction is the enemy when it comes to smooth shots, so grease would definitely help if you have no room for washers.

not quite sure how the secondary parallelogram on the back side of the jib helps. I doesn't look like it would tilt the camera bracket apart from keeping it level while booming up or down. You would get the same affect without it.

I would think that if you pull or push on the lever sticking up at the back of the jib, the result will be the jib moving up and down and the camera staying level. Just pushing the weights up or down will give you the same result .

Nice to see young guys building stuff instead of just playing with the X-box
 
im confused, if this only weighs 35 pds then why does it not tip over? What is on the ground for a footing? can you show a wider shot of it so I can see the whole thing?

I made a swivel arm to shoot a haf circle arc shot but have many issues with weight distribution and tipping , bouncing and swaying. mine is a hands free one though so I rely on the base to hold it up.
 
There is a really clear picture of how it is being held up. And if you read the beginning, it says there also. The whole rig is held up with a speaker stand; the adjustable mount is replaced with a 1.5 inch piece of barstock.

I have thought about selling them, but I have to figure out more on how to mass produce them. Plus mine isn't 100% perfect. The holes and welds aren't perfect, and the discs that the "arm" rotates on were just cut with a plasma from squares. If I mass produce or sell, I will get discs that have been milled and cut with a water jet for perfection.

A whole nother issue is powder coating. I could either powder coat them, or just paint them with black Rust-Oleum spray paint.

As for the arm rotation, if you make 2 identical discs and set them on top of eachother, it seems to rotate without problems. When I go back to my cousins shop on Wednesday, I am going to add an acrylic disc between the two.

Hey TC, you live in Northridge? That's funny because I live over in Chatsworth.


Real quick...Does anyone have any ideas for strong mounting of the camera to the sled? i have the usual 1/4 inch tripod screw and all, but I just don't feel that it is enough. What ways can i make this a better mount?

What I can help you with is something FAR better than adding an acrylic disc.
I'm working on my crane at the moment, and I have been testing out a GREASE to go between the two plates.

I'm in the UK and came across this "SMART GREASE" which I ordered from Manchester University. It makes the system like a fluid head, it makes it almost impossible NOT to get a VERY SMOOTH PAN.
It stores Energy and then releases it in a controlled way.......that is what I call SMART!!!
