recoveringbuilder Posted February 24, 2019 Share Posted February 24, 2019 Because the middle part of our roof was built on site rather than of roof trusses there were loads of lengths of 8x2 and 6x2 brought on site @ 6m lengths and we now find we’re left with a good few, we still have our garage to build and are now trying to think about getting this done as cheaply as possible, we have plenty of insulation etc left and are wondering if a joiner would be able to make trusses up from the timber we have instead of us having to buy ready made trusses, anybody any experience of this?

PeterW Posted February 24, 2019 Share Posted February 24, 2019 How big is the garage..? May need to buy a ridge board but 6x2 is ample for anything up to 3.6m spans at up to 45 degrees. Link to comment Share on other sites More sharing options...
recoveringbuilder Posted February 24, 2019 Author Share Posted February 24, 2019 It’s 6mx6m picture attached Link to comment Share on other sites More sharing options...
PeterW Posted February 24, 2019 Share Posted February 24, 2019 How many lengths have you got ..? And is the brickwork up yet ...?? Link to comment Share on other sites More sharing options...
recoveringbuilder Posted February 24, 2019 Author Share Posted February 24, 2019 No , no brickwork yet, we were thinking about not building this year until the finances recover but depending on how cheaply we could do it with leftover stuff which at present is lying around outside as we have nowhere to store it, we may just be able to manage it, there are probably about 24 lengths in all , some 8x2 and some 6x2 Link to comment Share on other sites More sharing options...
PeterW Posted February 24, 2019 Share Posted February 24, 2019 So... if you had the builder build with brick piers at the 2m and 4m points - just a brick depth, to give you some strength then you could use the 6x2 as rafters. They will be about 3.7m long, depending on the rafter tail so plenty of length. Will need to make at 600 centres, so 10 sets of rafters goes through 20 lengths. The ridge board will need to be an 8x10 so that is another gone, and I would pair up the ones over each pillar to make an A Frame at ceiling height, and then put a 2m offcut on every pair 1/3rd way down as a collar truss Should keep the joiner busy..!! 1 1 Link to comment Share on other sites More sharing options...

Oh he’s used to that, every time he thinks he’s finished we come up with some other idea! We just haven’t run this one past him yet! 1 Link to comment Share on other sites More sharing options...
PeterW Posted February 24, 2019 Share Posted February 24, 2019 If he’s good then he can rip and 8x2 down to two 4x2 wall plates and that is something else sorted ..! I built a temporary staircase from rafter offcuts and spares - was more solid than the proper one ..!! 1 Link to comment Share on other sites More sharing options...
