That’s what I figured, though it works on a cheap shopper that I have. If I don’t go full on custom the tubing in question is 631, can it be pinched inside and out without compromising it’s strength too much?

Let me guess - chainring swaged to the crank (no spider), gas-pipe tubing to retain stiffness despite the crimps, not strictly speaking street-legal clearance between tyre and tube? There are ways and means, but as I said, if you want proper clearance and the ability to use any track chainset, you're too short of space.

There's your trouble. Allowing proper clearance on the tyre and the chainring spider, assuming a conventional track type design, you have about 9mm width available where the chainstay passes between the tyre and the chainset. It's not an insoluble problem, but it's not going to happen with a straight steel tube running from BB shell to dropout.
