Hi guys, I have forwarded a page with mechanical properties of Douglas Fir wood in this email.  There is a rating for compressive strength and it has a little f in the description.  Not sure how to interpret that.  Can I get an opinion on that.  I need to know the compressive strength in psi.  This could be a cheap form of buoyancy.  I would make a glulam  then fibreglass the exterior to waterproof the block.  Of coarse as always i would make a sample and put it in my large pressure chamber.Thank you in advanceHank
