Rotary Table CNCing

[irving2008]

Never one to be phased by my incompetence or lack of skills (just a learning curve right?) if I decide to fit a thrust bearing at the lower end of the worm spindle I reckon there are two options:

1/ mill 5.5mm of the bearing housing and fit a 10x18x5.5 ball thrust bearing, then bore out the table body to 20mm dia at the right depth for about 6 - 7mm. Assembly would be put the worm in, drop the thrust bearing over the spindle, push to one side so that the offset bearing can be inserted over the spindle and into the table body. See pic...




2/ manufacture a new offset bearing, 5mm shorter than the current one and bored out 8mm not 10mm. turn down the worm shaft to 8mm and use 8x15x5 hrust bearings each end. Or maybe reuse the existing offset bearing but line with a 8mm ID, 10mm OD oilite bearing. This won't require boring out of the table body.
