Steam bending advice

I need to bend some 3/16" oak and I know enough to know I shouldn't
overcook it. Can some one give me a guideline on how long to leave it
in?
Thanks in advance,
Phil Brown

Tried it dry, no luck. The bend is quite tight.

Well, if the chamber isn't doing it's job, then it's being
unreasonable.

Yes, some steam has to escape.

I don't know if you can find it, but Norm of the NYW did a show on
this exact subject. He bent oak into a victorian style hat and coat
rack.

Totally dependent on your heating setup and the ambient temperature.
Rough guess, 15 minutes is all you'll need if the chamber is
reasonably tight and you're putting a goodly amount of steam into the
chamber.

Details.
The piece was a oak about 3 1/2" wide to trim the inside of the window
and make up the gap between it and the trim on the very uneven wall.
The trim piece is made from two carved twin bed head boards glued and
biscuited together.
It ended up being about 7 feet long. I made the box from a piece of
waste ABS pipe with an inlet glued to one end and a relief hole-about
3/32"-at the other. Very important. I cut a piece of plywood to sit on
the boiling pot on the stove and bored a hole to fit the inlet pipe.
Nothing needed to be really close fitting and little steam escaped on
the way to the box. Slope it so that when you open it you don't get a
cascade of boiling water on you when you open it.
Cooked it for about 9 minutes and it came out pliable and went into
the form-an identical window I have yet to install-easily.
Have plenty of clamps-I had 15-and at least one other pair of hands.
You have about a minute to get it into shape.
All in all a very satisifying experience and the result was one happy
girlfriend.

Pete, your memory serves you well, he did split the oak stock rather
than saw it.

Soaking a small diameter piece like that in Downy (Use a capped PVC
tube) works very well. Reusable too. No heat.

Forgot to mention to dilute with distilled water. Some wood will
discolour.

God, I love it when people ask questions and fail, even when prompted,
to give clear examples of what the hell they're trying to do. Next
you'll be mad at me for not giving you the answer to an incompletely
posed query. <thud>

We need details!

How did you steam it and what kind of radius and length did you need?

I ask because I have a large front entrance that needs an extension for my
8" walls. The radius would be about 2-3' and about 6-7' across after bent.
Not quite 180 degrees.

Previously I attempted to bend soem 2" cutoff trim in MDF. I left it in the
closet for a few months and let it sloop naturally and slowly. I wasn't
curved enough when I took it out, months later and when I went to increase
the bend...it snapped! The stuff can't hold it's own weight but when you
bend it...it snaps???? GRRRRRR...

Well, then, best I can tell you is that when a veneer plant is slicing oak
the flitch has been steamed for 24 hours.

Here is one data point.

I watched a chairmaking demo where the guy "cooked" his 1" square, green
stock for an hour.

He was able to bend it to a 6" radius.

It was very cool.

I'd be concerned that the soap would interfere with paint/stain (gag)/
whatever finishing of the piece.

Regular cat lacquer worked alright. After a thorough drying, some
sanding and a coat of sanding sealer. Didn't try stain.

I took a seminar a Lee Valley Tools a few years ago on steam bending.
Learned that wood compresses inside the bend to form the bend (not
expands outside the bend) and that you can't uncompresses a piece of
wood so bent. Might be useful info to any new steam benders.

I would think about 20 minutes in active steam would be plenty. Pull it
out periodically and get a feel for where it is at. start with samples.
This should not be too difficult. If the bend is too tight and you get
splitting, use a backer along the outer radius to support the fibers.
I'm not sure I ever heard about over cooking. Guess it is possible, but
you are mopre likely to under steam than over, I would think.

When you say a "reasonably tight" chamber it should be noted the chamber
really needs to be reasonably loose, so steam can readily flow. A
reasonably tight chamber will result in too little heating and too much
kindling, at least by my definition of "reasonably tight":-)

I've always understood it is the heat that allows wood to bend, and the
water (steam) is mainly there to facilitate heating the wood w/o burning
it. Not saying soaking in cold, soapy water will, or will not work, but
for gradual bends, 3/16th thick wood can bend some with little fuss.

I recall that programme. From memory, didn't he split the wood,

How long is it and what kind of radius do you need? Unless it is quite
short and/or you neeed a very tight radius, you can bend it dry. Oak bends
quite well.
