I was wondering if any bowyers take into account the increase in clamping pressure when a hose clamp system is put in the heat box?

I have seen that a starting pressure of 70psi is commonly used.  That seems like a lot of pressure to me.  Using the "Ideal Gas Law" if a hose clamp starts at 70psi at room temperature it will reach 80psi at 150F.  Is this too high?  Does anyone account for this?

I am getting ready to -you know what- and want more data.

(I also want more Stone Ruination Pale Ale but the misses will be here any minute)  Is my typing slurred?

I use a starting pressure of 60-65 in my hose.  Some guys start with 70-80.  I don't think it matters much.  I've never had a problem.  Chad

I routinely glue up at 100psi. i wouldnt sweat the 80 psi at all.

I have always used 60# in my hose...Glenn...

I use 70 lbs.The thing that worries me is how long a plywood form will repedatly take these pressures. I plan to make all my straps to go all the way around the form.

Does this mean you will be ready to make the limbs for my "Warf"?

I've made over 100 bows on one of my forms and it still looks straight...Glenn...

M60gunner,
I will make limbs for your Warf.  You probably want me to practice a bit on other things so I hope that you are not in a hurry.
