Summary

THIS DESIGN HAS BEEN MOVED TO YOUMAGINE:
https://www.youmagine.com/designs/steadycam-mark-ii

Reasons:
http://marcuswolschon.blogspot.de/2014/01/leaving-thingiverse.html

This gimbal converts a sturdy car-mount for a laptop/camera into a steadycam.

The current version does not have a bearing for the vertical axis, so you can turn the camera by attaching a large handle to the side (use both hands to control the orientation of the camera).

TODO: I did not yet asssemble it fully, to check if it is stable enough for the serious weight of the car-mount.

It's a work in progress and my internet is not very good on this train, so I'll describe it in more detail later.

----------------------------------------------
V0.2:
Status:
Was found to be too large. Something with the meassurements was off.
Probably specified diameter as radius or something.

Build time: (16mm/s, 0.4mm layers, 20% filled, 3 solid layers)
inner: 2h 34min (28.7g of ABS)
outher: 3h (33.8g of ABS)
grib: 13h 21min (155.2g of ABS)

----------------------------------------------
V0.2:
changes:

  • grib is M22, fits bicycle-handle
  • inner has the right size
  • cleaned up the constraints on the grib
    Build time: (16mm/s, 0.4mm layers, 20% filled, 3 solid layers)
    inner half: 29min (5.4g of ABS)
    outher: 1h25min (16g of ABS)
    grib: 5h (57.6g of ABS)
    ----------------------------------------------
    V0.3:
    Some minor improvements for easier fitting but Alibre crashes reproducably on save. Will take a wile.
    ----------------------------------------------
    V0.4:
    reconstructed "inner" from scratch.
  • better grib on bearing
  • easier insertion of bearing
  • tapper against inaccurate diameter due to melting first layer

Build time: (16mm/s, 0.4mm layers, 20% filled, 3 solid layers)
inner half: 36min (6.8g of ABS)
----------------------------------------------
V0.5/v0.6:
less snug fit on shaft, bearing and bolts, shorter grip.
TODO: I am not sure if the "outher" ring is thick enough to support the weight.

Build time: (16mm/s, 0.4mm layers, 20% filled, 3 solid layers)
inner half: 38min (7.1g of ABS)
outher: 1h 36min (18.3g of ABS)
grip: 4h (45g of ABS)
----------------------------------------------
V0.7:
Status: considered a working prototype
outher did not fit, too much linear play between bearing and next part.
Made sure all diameters are matching with 1mm distance on bearings and 2mm rotational against collisions.
Added a 1/4" hole to mount a camera-handle on the side (for both, left and right handed users) to control the horizontal turning of the camera.

Build time: (16mm/s, 0.4mm layers, 20% filled, 3 solid layers)
inner both: 1h 23min (15.6g of ABS)
outher: 1h 37min (18.5g of ABS)
grip: 4h (45.7g of ABS)
----------------------------------------------
V0.8 and SteadyCam Mark II:
Status: work in progress
changes:

  • moved handle below the center of gravity
  • handle can rotate freely

Instructions

See
https://sourceforge.net/userapps/mediawiki/marcuswolschon/index.php?title=Projects/Camera/Steadycam
for the assembly.
There is a discussion about this at
http://hbsboard.com/index.php?topic=4931.msg42798#msg42798

Abstract:

First make sure the bolts fit into the 608 bearings.

Then glue them into their holes. Do not attach the bolts yet. You may need a bit of blunt force. Not too far in, make sure the 608 rotate freely.

The 2 halfs of the inner ring go around the extended inner shaft of the car-mount just below the head.

Then add the nuts and the outher ring. You need to disassemble the upper turning joint (see photo) and remove the nut from the slide-out fastener (see photo) to move "outher" into position.
The M8 nuts are supposed to cut their own threading into the ABS for a good, tight fit.

Then the "grip".
Attach a bicycle-handle to the grip for added comfort.

Done!

It works!

I am currently working on some improvements in

(moved) SteadyCam Mark II

I used netfabb to align the STLs with the bottom plane and started printing.

v0.2 was aborted when found to be too large. I'll get the micro-caliper and check my meassurements...

v0.3 comming soon
