### Paradise ponders: exploding saws, hydraulic ignorance, and wooden trigonometry edition...

Paradise ponders: exploding saws, hydraulic ignorance, and wooden trigonometry edition...  Yesterday morning I started on the project of building the cedar shed kit that arrived the day before.  The shed is going onto an existing concrete slab, but there's a small challenge there: the slab is sloped (3.5" in 10'), and I'd kind of like my shed to stand up straight.  The kit includes a plywood floor built on cedar 2x4 “joists”.  After examining that floor's design, I figured out that I could support the floor on four pieces of pressure-treated lumber, nominally 4" thick.  The height of each piece would be different, varying from 2" to 5.5", to correct the slab's slope – I actually got to use some trigonometry to figure that out.  I'd also cut each piece of wood using a small angle (1.6°) so that the tops of the pieces would all be in one plane and level.  Sounds easy!  So off I went to Home Depot to buy my four pieces of lumber.
