Both 3D models are of realistic size and can be used in projects without any scaling. The 3D models have been modeled based on some pictures found in an old company's catalog where, beside the table legs, also various other wooden products made on the lathe can be seen.
In the pictures you can see what the table legs look like.
Table leg 1: 762mm x 51mm x 51mm (30' x 2' x 2').
Table leg 2: 736mm x 63,5mm x 63,5mm (29' x 2 1/2' x 2 1/2').
