I am trying to find a place in my basement to store my kayaks. Unfortunately, all the walls are out since they there is something next to each one of them (gas meter/sewer pipe, heaters, washer/dryer/stairwell, closet). However, there are two lally columns in my basement supporting the main beam - these don't sound hollow when I knock on them with a metal object, but they do vibrate a bit when I knock on them with my fist. I have a crazy idea to mount a sturdy piece of wood to the lally column, maybe a 2x8, using U-bolts, and then mount a kayak rack to the 2x8. Something like http://www.amazon.com/Malone-J-Dock-...8492607&sr=8-1 . Basically, create a pseudo-wall surface which would be attached to the column via U-bolts. The additional weight on the column would not exceed 100lb, though the rack/piece of wood would put some shear stress on the column. Now, the column is pretty thick (4" in diameter, I believe)... but is this a good idea? Can attaching something to lally columns possibly be against building codes?
