Pulley logic/location?

[mhorowit]

I'm looking at Crispy's interior and see at least 3 different sized pulleys.
Thinking ahead, it would be nice to know what size goes back where. Lots of pictures should solve that problem; however it would also be helpful to understand the pulley logic.

Why are there multiple sized pulleys vice only one size? - Mike

Mike,
There are only 2 sizes except for the brake(very small)and trim pulley(very big)niether of which are pictured. I assume they used the different sizes to allow more space...I really don't know.On a different note,all my pulleys are new ball bear pulleys....and they are very nice.

They try to use the largest diameter pully possible, with the space permitted, to keep from bending the control cable any more than you have to... the larger pulley will put less stress on the cable, via bending forces. At least that's what I remember them telling us waaaaaaaay back in A&P school.

all my pulleys are new ball bear pulleys

All mine are the originals, re-bushed with phosphor bronze plain bushes...much smoother than those expensive ball-bearing ones

Lee,
I really like mine but either way I had to buy several.After Crispy cooled off from the fire there was only a couple that were salvaged,those being the rear trim pulley at the elevator and all but one of the small brake pulleys .
