That's for a 14"? 8" from the bottom of the flat to the hinge split?
High probability. See "trade size".
10EE's nominal 10" clears 12.5" "actual". Stamped right on their data plates.
Cazeneuve "360" metrifuckated "center height" is a nominal 14" that falls just a skosh clear of 16" at the inner edge of its ways. I mought could use your one, relatively minor base modifications, if I didn't already have the OEM Cazeneuve steady, for example.
Basically, yah gots to measure yer spindle with a DC in it above the SAME vee and flat any given steady utilizes.
Or could be MADE to do, given that steady's "in general" are not all THAT hard to modify. Nor fab from scratch.
"Travel" rests are the goods as tend to be harder to DIY, brain-sweat-wise as to sorting shape and where and how to attach.
Last time I looked, PM threads had fotos of FIVE different travel-rest styles for the Monarch 10EE alone. Not DIY's, either. Monarch built or one of the "usual suspects" for regular buy-in of respected third-party goods.
Anyone with access to a mill - or who could gin-up a baseplate with an ignorant hacksaw, would not be taking much of a risk to adopt an "alien" steady, any lathe from about an inch LESS swing to four inches GREATER.
Yah can line 'em up "manually" with crude methods even with no mating Vee way, because... once shimmed, blocked, and locked-down, they don't have to "traverse" like the carriage once put to work, nor is there meant to be any "twisting" force on 'em, nor even MUCH torque. Just basic gravity, and a bit of cutting-force deflection, mostly.
Providing... of course... that the lathe-hand ain't being any more foolish-optimistic than "normal" at ripping record-breaking chip!
just needs new headstock bearings or bearing liners.
