Fuming setup?
« on: June 27, 2015, 11:48:40 pm »
Hey guys n gals. I'm about to try fuming my hickory bow I recently finished and am looking for ideas about how to get it done. I was thinking of standing it up in a cooler that also holds the container of ammonia and tenting the whole works with Saran Wrap. Is this how it's usually done?

Willi, don't play around with that cooler or container stuff. Just use a plastic tube about 2 meters long, seal it on one end with gaffers tape and work in a piece of cord about 1meter long. The cord is for free hanging in the bow in the tube. hang the whole setup at the ceiling, the other end of the tube should reach the floor. Put the pot with the ammonia in this end of the tube and seal with some rubber band.

That's all!

You can watch the tranformation through the transparent plastic esily. I usually go for one day ub to seven days. When putting out the bow let the damp vaporize out (go out for that - it stinks heavily).

Good luck!

Thanks Simon! They didn't have any clear tubing in the home supply store near me so I picked up some HDPE. I suppose it won't hurt to open the thing up every 24 hours or so to check on progress. So how do you contain the ammonia solution inside the pipe? Use a small bowl in the bottom?

I just set a fuming tube up today.  :) Seeing Simson's recent update and having a primitive styled osage bow needing some aging, I thought I had to try it! I used my steam setup, which is a couple of 4' sections of 4" chimney pipe, joined with a tee. I just capped the tee and the top end and rested the bottom end over a plastic container of ammonia with the lid off and leaned it against a tree. Just made sure the bottom limb bow tip didn't go in to the jug of ammonia. After 4 hours, only very slight change, barely noticeable. I will see what it looks like in the morning.

I suppose you could use the plastic tube from a Diaper Genie refill to do this?  It's blue clear plastic, at least you could see the darkness of your project without opening it.
