I know about clamps...so I put the bed over the wood all night, thats work very well.
I can`t find a ....in trussrod in this stupid country, so... I will build one tomorrow, will be a lot of pics, and may be I post it in the workbench too, just in case somebody wants to know how DIY. (it`s work, is not my first trussrod, we call it alma in Argentina, wich means soul)
