* Hirata-san produced a near-final Inventor assembly of the BS on the assembly frame. * [[attachment:160419-チャンバーカバーⅡ型.pdf]] |
* Type B Past Week Summary * Fabian, Mark and Liu-kun did BS installation at Kamioka: * Debugged the issue with the BF keystone being tilted enough to cause rubbing on the yoke for the magnets. It was solved by moving the yoke ≈1 mm taking advantage of the oversized holes. * Measured the height of the payload as a function of trim mass. The BF spring seems to have a slightly lower load capacity and a rather higher spring constant than when it was remeasured by Hirata-san. * Removed IM trim mass to set the average height of the keystone to the CAD value. * Moved IM trim mass around to set the pitch of the dummy BS. * Hirata-san * TBD. |
