- Prototype 19-0/1 concept (following what was shown previously): ~500mm travel, ~400mm length
- 2x ~250mm travel, ~400mm length rails (carriages ~150mm length, fastened together) McMaster # 8379K6 , stacked
- Prototype 19-0/1 concept (following what was shown previously): ~500mm travel, ~400mm length
- Alternative: 1x ~250mm travel, ~400mm length rail per ring, to move both 1/4-shells and meet in the middle
- not preferred: less assembly flexibility, less clearance when connecting handling frame due to less travel
- Alternative: 1x ~450mm travel, move rails to edge of table so single rail can reach far side 1/4-shell
- not sure about rigidity cantilevered from bearing at one end, or about table space to enclose.
- Alternative: 1x ~250mm travel, ~400mm length rail per ring, to move both 1/4-shells and meet in the middle
Candidate vendor parts:
- 8020 Inc. # 6516
- slide on 1.5" t-slot rail. add #6800 locking handle. not preferred due to sliding friction and height.
