Determining equal spacing of vertical bars or muntins in a window can be a head scratcher.
I don't know where I learned this trick or who taught it to me, but it is one of the neatest tricks I've learned in drafting.
You determine how many muntins you want across the window. With this method you haven't got a clue how wide the spacing will be and you don't care! You simply draw a diagonal from one side of the window to the other adding one unit to the number of bars.
Here I want four divisions, so I put 5 at the edge of the window.
Now you just mark off the units, 1,2,3 and 4. Here I'm marking 2 and 3.
That's it! Four equally spaced divisions.
P.S. I've just shown this roughly done on the window paper pattern. Greater care will be taken when the window material is scribed for the bars. The window plastic is sandwiched between two pieces of MDF to prevent shattering and ease profiling.
I think I have anticipated all the plumbing raceways and access points that will be needed when the engine is mounted onto the floor of the pump room. The feet for the diorama are made from Polylastomer®, a durable non-staining, non-marring plastic, superior to rubber in all respects.
The planking is again Southern Pine, a nice softwood with interesting grain patterns when stained. It comes bonded to a paper backing.
Interesting observation, but I am quite firm on where this model will end.
I have my eye on an engine in England that I really wish to acquire in kit form. If I can, it will propel me into another major construction diorama very similar to the two year project with the 19th Century Steam Driven Machine Shop.
This little diorama should be completed in May. Then we will see what's up - health permitting.
