Traditional timber frame

Recommended Posts

Hi , not sure what he is doing for the walls , I know he is going to try and make bifold doors but that’s a long way off , and no I will not Mill him any bigger beams as when he had a mate with a woodmizer in he would not Mill a small butt for me .Thanks guys as I was just curious , it seems my thinking was about right .

The  research I've done and the info I've gathered would indicate he's way off the mark in relation to size he's trying to span and material he's using. The DF I'm milling is for a sunroom and the max it will have to span will only be 4.5m, I'm pretty sure I'll be using a bit more than bolted up 4x2s

So many variables, and most tables will include relatively generous/stupidly generous  Factors of Safety.(and I think structural timbers are mostly sized to prevent deflection or undue "springiness")

Anyway, are we talking an overhead span (presumably otherwise midspan supports at ground level)

Being a garden room, presumably single story?

So what mid span loads will the overhead timbers be supporting, or can they be artistically fabricated as part of a truss, ergo much stiffer?

Fabricate  a trial beam or truss at ground level and test it for stiffness?

I cannot imagine sudden failure i.e. there will a LOT of deflection to give reasonable warning prior to failure.
