about that steam bending....
« on: May 29, 2016, 11:12:28 am »
Hey fellas,
    Been several discussions on here about steam bending wood. Well here are 3 examples of steam bent wood that is more than 100 years old.
    In the pics there are 3... 1/2 wheel rims...these were made and kept as "repair" parts. The top one is for a buggy and is about 1-1/2" X 1-1/2" white oak.
    The second one is a heavy cargo wagon rim and is about 2" X 4" and made of white ash. The third is a general duty wagon wheel and is about 2" X 3" and also of white ash.

     The rims have been stored in an "open-air" wood shed for the past 30 odd years and in a barn before that....There original shape has not changed enough to make them "not-useable" Steam bent wood will hold it's shape.

Rich,
        I agree, steamed in reflex has worked great for me...No issues...Temperature is temperature internally...The thing I like about steam is it only takes 5 minutes on a 1/2" thick limb to bend like rubber...

Keep in mind that nobody has been bending these in the opposite direction though.

Steam bent wood gives hornbows their shape and they keep it too. 'Enhanced' slightly by sinew but still :)

 Aren't you forgetting the horn  being glued to the reflexed surface?

 PatM,
           How about it? what do you think about steam? Got any positive info you could share with us rookies...?

 I steam static portions of a bow.

Don't forget there is also chemical bending of wood which is used commercially, although I don't know if they were using that method 100 years ago

Oh yes I forgot about that.....???
Do you mean the horn that is less stiff than the wood to which it is glued.....The shape of a hornbow is entirely reliant on the wood.
Do you have a point?!?

   You don't think it aids in holding shape despite its lower stiffness?

I'm a bit confused about that statement.  All that I have read about hornbows, never have I seen mention of the core wood being steam bent before gluing the horn and I did not do this to the ones I have worked on.  I"ll have to look at Adam's book again, maybe I missed something

In Adams book he uses steam to bend his maple cores before glueing on the horn.
I think it's a perfect combo of horn, sinew, and core which allows a horn bow to keep its shape.
Although my bighorn bow with no wood core seems to hold its shape just fine

Interesting Rich. I've noticed most of the Amish buggies around here tend to have round wheels too.
