What causes temporary set?

[Don Case]

Thanks for all the replies. I've got a handle on what is happening now. I know I've been impatient and as I now have a good stockpile of OS staves plus a few yew and Crabapple and stuff I will soon be working with fully dried wood. In the meantime I have made 5 bows of more or less success so I have learned a bit of tillering. For some reason buying a stave or using a board just don't appeal to me. Independent or cheap I guess   I can fill the time trying to make arrows. And once I can pull this bow I can practice shooting.
Thank
Don

I was once prejudice against bows made from exotic woods and grasses. But once you make one they're quite enjoyable.
Though I still prefer my staves.

I've had OS sit for 2 yrs and still be too moist.
Just make sure when you pull it out of your hotbox you let it re-acclimate
Have fun bud:)

  Besides being properly dry we also have to make sure we have enough wood to accomplish a specific design without taking too much set.

When the moisture content is too high, the set is usually permanent, at least it is for my bows/staves.
My bows usually show a certain amount of set when unstrung anf d then return too. Like Pat said your case shows  a bit more.
Check measurements again.
