how long when using steam?????
« on: May 13, 2013, 05:30:49 pm »
Hey guys,
when you are using a stove top to steam bend a bow about how long do you steam the bow until you put it in the recurve form? and also do you put the belly of the bow down (steam hitting the belly) when steaming or do you put the back down.

Just remember that you only have seconds to get it bent or clamped.
Sounds daft but I find it best to practice the "run" from pan to form so you can get it in one fluid motion.

I get my clamps set and do a practice run every time. Try to make your bend in one motion. You have about 15 seconds from the pot .

So, how long do you wait to start tillering again after steaming?

Weight the bow before you steam it and then wait until its back upto weight after the steaming.
I forget to do this pretty much every bloody time so i just give it a few days.

About 3-4 hours for me. Sometimes less and sometimes more. It depends on what else I have cooking at the moment.

When I steam wood, I put it on high and let it come to a fast boil, then steam it for an hour and a half.  As it's boiling, i set up my press and clamps.  Then after an hour or hour and a half of boiling, I pull it out fast and clamp it down as fast as I can, then let it set in the press for a week, then I go back a week later, and do the other side (If what I'm doing is recurving the tips).

Its quite easy really.  Just a bit time consuming.

Would it help to keep a heat gun going on the bow while taking your time to clamp it in place?

Not really.  It doesn't make a difference.
Just get the bow onto the form within 5-10 minutes and you'll be good to go.
