In an earlier post to this thread I included some photos of the Easybuild floor moulding, this post provides the dimensions of the cross-section of that floor moulding. In the following I have referred to the top part of the longitudinal trusses of the prototype as the "central girders" and the EZ moulding represents those items as a "T" section (hence reference to vertical and horizontal parts of the central girders).
* width between undeframe solebars = 52.5 mm;
* depth of inside face of solebars = 3.95 mm side 'A', 4.10 mm side 'B';
* distance between vertical faces of central girders = 13.9 mm taper to 14.1 mm;
* thickness of vertical section of central girders = 1.6 mm taper to 1.2 mm;
* width of horizontal part of central girders = 4.75 mm.
* thickness of horizontal part of central "girders = 1 mm.
The two central girders are "central" with respect to the underframe solebars with the distance between inside face of solebar and vertical section of girder at 17.6 mm - 17.7 mm. The vertical part of the central girders appears to be central to the horizontal section of the girders.
How does that compare with the space required for your Mk.1 truss etches?
... I will have some jltrt etched trusses spare that may well do the job for a few easybuild coaches when combined with some suitable angle.
Where will the additional angle be used in the trussing?
When will you be able to post a photo of the etches fitted to a floor moudling?
