Hi Matt, thanks for your videos-I’ve learned a lot. I was just wondering if it's possible for a surveyor to set up a peg according to the outermost edge of the foundation instead of the boundary, or do surveyors only set boundary pegs while the builder sets up all the profile stuffs?
We are removing the old cedar ship lap cladding from our 1970s house. We plan to replace with a ventilated cavity and cement sheet cladding. How would you suggest modifying the existing aluminium window frames so the new cladding fits flush?
Do you have video that shows height above plate calculations showing calculations for roof tile etc when determining overall height for rafter lengths?
Thank u very much I got my grang ma house the roof build by round beam 9 m long to 4 m width 4 round beam broken at end of beam left side . I really don't know why !! Asa Baghdad Area òf section 300 cm/2
Great videos thanks! I cant see any mention in AS1684 but it definitely illustrates it, is there a particular spacing needed between the double joists under load bearing walls?
I am a little late to the party but these are really great videos. I started building in the late 70's stepping off rafters and scratching my head for a long while. Then got into the exacts, baster hips, Very enjoyable to watch. Thanks
After spending a solid work day messing around getting this wrong using all the right math, and then hours on RU-vid looking for someone with the answers I was looking for, finally here I am watching your video. Honestly, I'm glad I had this so twisted because now I will never forget what right looks like. I'm looking forward to going to work tomorrow and looking like a dang super star. Thanks!!!
Thanks Matt for sharing your knowledge. My question is, all these terms are also applicable for other materials such as steel and reinforced concrete structures?
These terms are from a regulation covering timber framing. When dealing with steel and concrete you would probably need to refer to engineering principles.
In Australia we have strict span tables to abide by or an engineer can size building elements. You will have to refer to the building authorities in your area.
16mm bar would be way to tough for a little guy like me to bend. Trying to straighten a bent bar would be even harder, and it would weaken the bar to bend it back and forth.
On the creeper rafter It looks like the deduction marks you have done are on the right of your run line which would actually make the creeper rafter longer rather than deducting it. Is this right? Thanks
I've just figured out my silly mistake, because you are moving closer to the tail end it actually makes it smaller! The summary video at the end helped me realise this so thankyou!
Great video I find your videos have a lot more detail and easier to understand than "the other' chippy trainer on youtube so thankyou! One thing that i don't understand though is why you deduct the crown end rafter when it butt into the ridge board? thanks
Deductions are taken from the “side” thickness of what the rafters are butting into. Common rafters Butt into the side of the ridge, but crown ends Butt into the “side “ of the commons. Half the ridge off the common. Half the common off the crowns end.
Thanks for the so many great videos you put up! One question, are there any general rules in which direction you run your ceiling joists? Do the majority run parallel with your common rafters and then run perpendicular to be parallel with the hip rafters? Is this always the case? Thanks
We do this wherever possible because two rafters and a ceiling joist will form a triangle to give a structurally sound roof shape. You would only do something different if there were a reason, like hip ends or unusual roof shapes.
So, if I'm in a roof and want to figure out the rise where do I put my tape measure? The X Y line? or the underside of the ceiling joist? Then where do I measure vertically up to? The Apex?
