It'll be a 1x8 with a chainguard to keep the chain from falling off, so I'm not too concerned about chainline. I seem to recall @
noglider did this with a TA with tiny crank arms, but I think that was an IGH setup.
I am doing the same thing, for a vintage look Klunker (1946 Schwinn DX), and the TA cranks look perfect and "period correct", but I don't want a front derailleur.
Additionally, after a bit of math, if I use the master ring on the front (53), I would need to use a completely silly rear freewheel that looks like a spoke guard. So, I am cutting off each of the six arms, radiusing the ends, and bolting the middle ring (44) only to what is remaining, like an external spider. I think this will look Klunkerish, without being obtrusive or silly, and have a good chainline
Alternatively, I think you or I could bolt a TA "copy", Ticinoi, on the the 5 bolt arm itself, available in a 42.
Although the Ticoni could arguably be a few mm outward on the chainline, but going from 44 to 42 might let you ride on 16 instead of 18 in the rear, curing itself.
