Here is the current progress.  Most of the edge pieces had to be made the same way.   Everything is just loosely placed at this point.  I will glue everything down once all the pieces are done.   All that remains on this part of the pattern are the edges to the legs, the feet, and the lettering.

I have to look at it over and over in admiration.

Here is the final pattern of the back side.  It is complete other than finish (polyurethane).   I put the actual seat frame next to it for comparison.

And here is the final front side pattern.   I added up my hours ... 230 so far for this pattern.  About a third of the time was measuring and creating drawings to work from. 

There are eight total patterns needed for the seat:
Aisle side frame - this pattern
Window-side frame - done - see earlier in this discussion
Two link arms for the seat back
Plate for the seat back attachment
Two different bottom plates for the linkage
Armrest

6 more to go...

I am in awe of your creativity and skills! We are very lucky that you choose to share them with the WW&F.

Just curious, the lettering that can be seen within the 2 patterns appears "normal" and read-able. Shouldn't it be in reverse? Perhaps I'm missing something.

The back-and-forth of normal and reverse images for the casting process can be confusing, but this is correct. The wood pattern is what we want to end up with. Each pattern gets a frame ("flask") on top of it which is packed with casting sand. When the pattern is removed, the sand will hold the reverse image. The two halves ("cope" and "drag") are brought together to form a complete cavity into which the metal is poured. Since the sand image was reversed, the metal will be the "correct" way 'round, the same as the wood that initially formed the mold.

Harold, your name as pattern maker should be somewhere on that casting too.

For sure Harold! WW&F too?

Is this something that could be sold to other restorers?

I did not mean the pattern but the finished casting.
