Title: Fuming
Post by: DC on February 24, 2019, 02:46:18 pm

Does anyone know if fuming will straighten out any curves or corrections I've done?

I did fume a couple static recurves,  did not affect the curves. Did it with household ammonia tho, not very strong, over a couple days

I'm a skeptic, cant help myself. Two things I wont do for another 10 years, or so. Hollow limb bows and fuming. I need to see the long term affects, if they exist. Ammonia is wicked stuff and for me to believe it does nothing adversely to the wood will take time.

I have done a fair amount of fumed bows (even HLD ones O:) ) and have not noticed any previously heated curves come out or back. Haven't noticed any side effects on fumed bows even after a few thousand arrows

I'm kind of with you on this, it is wicked stuff. But if we all waited 10 years nothing would get done ;D. I fumed some Pacific Crab tips and they turned a beautiful grey so I want to try this.

Dratera- I use household ammonia, I can't find anything stronger so, yeah, it does take a long time. I found that if I put the bottle of ammonia on one of those coffee cup warmers it speeds the whole thing up quite a bit.

Thanks Leon

Just an update. I fumed the bow for 4 days and it's been drying for about 3 weeks and the sideways bend I took out originally has come back. I don't think it's the fuming as much as the bow getting soaking wet while it's fuming.

that makes perfect sense,,
I think on a bow like that,, maybe a different finish with less moisture,, might be the way to go,, that being said,, can you straighten it back ,, without messing up the fumed finish,,

I just finished steaming it again and it looks like it didn't bother the "finish"

I would love to see some before and after pictures.

I don't have any before pictures but this Pacific Crabapple, it's white wood like Maple. This about 36 hrs fuming.

Really nice! Thanks for sharing. How about tight bond 3? Will it dissolve it and make it come unglued?

Don't know about Tight Bond. I've never used it.

I glue my tipoverlays with titebond 3 and have never had one come loose after fuming...

I have done heat correction on Laminated bows glued using TB3 and never had them de-laminate.  This extra moisture deal using water based glue is just a fear.  I have literally glued up thousands of board feet using TB, from doors to windows to boxes and of course bows.  And worked on them aggressively the same day or the following day.
