W.M., Gonna have to see some cool pics at some point here on these bearing supports (not so creative on my own, need to borrow some ideas!). StanRUS, is that the York kit you have pictured above? (too tired to google).
Regards, Bob
Bob,
I don't own, use & have never seen a York in person. The photo is from York's promo video, downloaded and using VLC player a photo snap shoot.

https://youtu.be/qfsUY6UVVgI VCL also can do slow motion and frame-by-frame, viewing the video that way I am less than impressed with the design of the carriage assembly, drive motor to boring bar interface (coupling). All the machines in the video have obvious boring bar run-out (not straight), that causes the carriage to wobble around...impedes bore machining accuracy-surface finish. Line boring IS NOT just about removing XXX amount of material but also how ROUND is the finish bore after the machining operation is finished...Roundness cannot be measured with any 2-point measuring instrument(s) all that gives you is a diametrical measurement across 2-points.
All the machines except (Hofmann or Italian type) that require removal of support bearings to use a stand-alone bore welder require some means to realign the support bearing(s) after bore welding. WM's York; remove the bearing support's 4ea mounting bolts, @ re-install alignment relies on bar-to-bearing fit...any perpendicular bearing support's FACE-to-Bracket face issue can result with a bit of bore axis displacement...
Older Climax Mod1149, NO spherical bearings, directly mounted to the support arms with 4ea 1/2"-NC bolts, 4ea 5/16th" jacking bolts to adjust perpendicular alignment & 4ea 5/16th" jacking bolts to adjust radial displacement (up-down-side-ways); NOT users friendly & very time wasteful...To use the 1149 without the mickey mouse procedure given by Cmax; LOCK spindle to boring bar with the spindle collects onto an ALIGNED BORING BAR, same for opposite support bearing (non adjustable-spherical directly mounted into the support arm) Lock collect to boring bar...push the arm hand tight against the work piece & tack weld @ closest point...if there a gap use metal scrap to bridge (washer, nut, re-bar, small wedges, 7018 welding rod with flux knocked off etc)...after tack welding both support arms...LOOSEN each mounting bolt (& face jack bolts) & retighten individually BEFORE loosening spindle-bearing collects. Loosen collects; bar has to slip back & forth easily!!!! Typically requires less than 15 minutes.
Set-Up Cones, all they do is hold the bar to approximate center-of-bore axis, even Engine line borers' set-up cones & support bridges just hold the bar to approximate bore C/L...for construction equipment I never use them preferring 4 legged adjustable spiders used to align the bar. My buddy uses spiders & aluminum disc.
Cmax, their BB5000 set-up video,' most of the time set-up cones are all you'll need'! Complete BS...
