Seats for the Big Birney

Back to the Big Birney car project.

Plan to unveil it in some state of completion for High Wheeler 2010, first weekend in March.
Just under 75 days away, not much time !
Spent much of last weekend figuring out how to make the Brill Waylo seats. Not a difficult project, but with no dimensions or plans, have to wing it best you can. Thanks to Mal Rowe in Australia yet again (He also supplied photos and info on the St Louis #7 trucks), he sent me some good detailed pictures from the Bendigo Tram Birney cars and seats.

Here are the patterns, affixed to the base of the mold box.
All styrene patterns.

Here is the finished mold, everything gets cast twice

except the seat pad to the right.

And here is the first mock-up, not complete, still needs the swing arms in place so that the back is elevated and the seat back can be "reversed", have to play with the castings a bit to make that work right (bit of a design flaw, but easily remedied). Next steps, figure out the fix for the seat backs, cast up a bunch of parts, and put them all together. With any luck, few casts per day, should have a complete set of seats for New Years. A MAJOR step forward !
