I am seeking help find a to find a pit for an HO 70 foot turntable which I am building for my new layout. HO 70 feet scales to 9-7/8 inches(244 mm.). The prototype is the Southern Pacific turntable at Port Costa which contrary to some sources is actually 70 feet according to SP records not 75 feet (some modelers have used 75 foot length for turntable this in order to use the 75 foot Diamond Scale turntable bridge and pit casting.)
Traditionally modelers have built up the pit from plaster and other casting materials. However, I am using a lighter type of construction with foam board and need to find a plastic cast 70 foot (or up to 71 feet..I can pad the TT bridge length) turntable pit that would 4-5 scale feet deep. Interestingly the 130 N scale turntables scale to about 71 feet in HO which would be acceptable. However I have yet to find a pit by itself or an unmotorized Heljan (same as Walthers) N scale 130 foot turntable kit. I don't want their motorized version.
Any help (or if you have an old Heljan/Walthers N scale kit you want to part with cheaply) would be welcome.
If anyone has 3-D printed an HO 70 foot turntable pit, please let me know. It would take a large 3-D printer to make such an object.
This is the layout at the moment:
