Large Scale Central

Stub Turnouts

Hi All !
New to list. If my request has been covered, apologies in advance.

Anybody have experience, or, information on construction of a Large Scale Stub Turnout. My efforts, to date,(scaled ou old NMRA data sheets and healthy dose of "imagineering) provide amusement now… I understand home built trackwork needs smooth, constant bends (problem with first effort.) present one works, but doesn’t resemble protoype photos I have to work with. Also transition point of curved route to straight section right before point rails causes trucks to “twitch” slightly.

Any and all suggestions welcomed.

Thanks, Chuck.
