  1. Here's a sample of some new things I've been making....(new stuff) and the complete list of all the parts I've been making 696551202_3Dprintedacc.1_16.2021.pdf New stuff 1.17.21.pdf
  2. I think post length should be altered to get the specific shot - either to change the lens height range and/or the rig's inertia. Choosing to configure your sled only one way is like playing 10 keys on the piano instead of all 88.
  3. mark- one of the design ideas with the Tiffen dock was to keep everything below the fork so that the Volt bits on the gimbal wouldn't be inadvertently hit and damaged. Using the Hill bracket with the Tiffen fork is possible, but there is more opportunity for accidental collisions.
  4. Correction- My pivots do mount to the SmallHD bracket (I forgot how it worked). The design makes it so that tilting the monitor does not try to rotate the tensioning screw. It's also about as thin as it gets. Slightly different versions of the pivots are available for TV logic, Stargate, and BON monitors to Tiffen's universal bracket. And I've made some pivots for different Tiffen fixed width monitor brackets, like the one on my trusty old Ultra2.
  5. Always improving and making new things... this time with a few items for Aero and Zephyr owners. Check out the pivoting small monitor mount, the plug and play 2nd battery mount for the Aero (AB or IDX with cable and jack), and the "big" pivoting monitor mount for 7" monitors. See the full PDF for all the bits I/m making. 3D_printed_accessories_11_21.20.pdf
  6. The Volt can handle a great deal of imbalance - it handles wind loads very well. For the big glass shifts, you'll have to crank up the tilt strength. Of course, a constant correction of imbalance will require more power - hence the typical work to get the sled in neutral balance for most shooting - less work for the motors to do. I think there are some videos on FlySteadicam of the Volt with wind and maybe one with an IMAX (??).
  7. Benjamin- Minor point: Tiffen's rigs have 1.50, 1.58, and 1.75 inch posts. The Volt can be adapted to 2" posts, but the other manufacturers will have to do the work - As Betz has done. It doesn't make business sense for Tiffen to do the engineering and testing etc. themselves, but they have been more than willing to cooperate to get the Volt onto other rigs.
  8. Typically this is a problem of the operator's posture. When you put any arm over your shoulder, the section closest to the body will pop up as you lean back. Same thing happens if you lean back when operating... and the Master arm is more sensitive to this (a design trade off in making it very isoelastic)
  9. I've made some new items... including this Zalex Longplate M bracket to IDX battery mount and cable. Please check out the new PDF of all the items I'm currently making. 3D_printed_accessories.small.pdf
  10. Most likely the centering of the pan bearing to the yoke is the culprit, based on the pictures. You might be able to shim it to get it more centered. More expensive rigs either have some mechanism to adjust this centering and/or much better machining and control of tolerances. You got what you paid for...
  11. Regarding the panning: If you've done the "hand-free" test and the rig pans, it may be that the pan bearing is sticky and needs a good cleaning. Or, alas, replacing. If the "hand-free" test shows no panning, then it's likely a combination of lack of pan inertia (typical of small sleds) and heavy-handedness, both of which are easily fixed, as described above.
  12. This is entirely Peter Abraham's fault. He asked me if I could print a bracket that fit under his Longplate to hold a BFD receiver. There's a lot of room on many camera builds for receivers, transmitters, and other accessories under his plate. One thing leads to another and there are now six new items for sale, and options for more. See the PDF for information. 3D_printed_iems_for_sale_8_31.20.pdf
  13. Another posting for the VGTBE. 3D_printed_iems_for_sale.pdf
