Perry reflex question

[Springbuck]

If you leave a wooden bow braced for a year or so it will take a permanent set. Do the internal stresses of a Perry reflex take a set and lose their effect after a while?

Do you mean just a blank sitting there? Or strung?

I once years ago, took a R/D blank off the form, that had cracked at a belly corner going into the form.  There were a couple things I wasn't happy with about it, actually, so it went into the "I'll come back to this later" bucket.   I started making way more selfbows about then, and it sat there for 5-6 years, year round in the garage and never budged an inch.

Eventually, I narrowed it and made a 25 lb bow for a young lady from it for her LARP hobby.

Heat and chemicals are the 2 ways of plasticizing lignin.  Once the cells are plasticized the wood can be re-shaped to a different configuration and once cooled will stay that way

So would there be any disadvantages to heating a core into reflex and then glueing your backing into place?

It would depend on the creep level of the glue you used.

OK. What happens to the wood in a strung bow, over time, that makes it take a set and why can't it happen in a Perry reflex bow?

[PatM]

It could, not sure why you think it can't?

[Springbuck]

  Yeah, I'm with Pat.  I would assume a Perry reflexed bow under STRAIN, like strung and left, WOULD take set.

 
Who knows, it might take a smidgin less, maybe at first, but it's gotta eventually.
