Jib Transfer System STEP Assembly File
Manufacture & Assembly InstructionsIn order for someone to build their own Jib Transfer System they will need:
- All materials outlined on the Bill of Materials
- The tools listed on the Jib Transfer System Mfg & Assy Tools List
- Full System Manufacture and Assembly Instructions
If you are interested in accessing the files separately, they are available here:
Sonar Installation InstructionsAfter the device is built, it is simple to install and remove from the Sonar as needed:
- To properly install the device for use follow the Sonar Installation Instructions
- To properly remove the device after use follow the Sonar Removal Instructions
Test Plans & Test ResultsA completed list of Test Plans & Results are shown below
The following are selected test plans that were easily documented and explained using photos or videos.
TP8 - User's Unobstructed Field of ViewThe following is a video of a team member sitting in the device while rotating in the device. The video shows the actual point of view that the user will experience while using the device in the Sonar
TP13 - Degrees of RotationThe user can rotate +/- 90 degrees from the centerline of the Sonar, which is 180 degrees of possible rotation. The image below shows the device in the locked positions on the port and starboard sides, each locked position is 90 degrees from the centerline.
TP14 - Vertical Distance between Seat and BoomOne major concern was that the user's head would hit the boom during transfer. The vertical distance between the top of the device's seat (where the user is seated) and the bottom of the boom was measured at 34.5" during testing. This is within the specified acceptable range, so most users should not hit the boom during transfer. NOTE: Users should still use caution during transfer because there is still the potential for a collision with the boom!
TP18 - Plywood Life Testing
During the Detailed Design Review in MSD I, there was
some concern with the use of our braking mechanism and
the plywood base. The team designed this plywood life
test to determine how many rotations the plywood base
could withstand before being compromised (compromised is
defined as the plywood having a groove of 0.25" or
deeper). The system is design for 13,500 cycles (5
sailing seasons). The pin was positioned 1.88" from the
center of the wood (3.76" diameter circle) to maintain a
tangential velocity of 2115 in/min. The test was run at
179RPM, so 13,500 cycles is 76 minutes:
The lathe was set to 179 RPM and run for 76 minutes (every 5 minutes the direction was changed between CW and CCW
