Nice brother, I was having a brain fart and before you got to the scarf joint I was cured, thank you.
Thanks Mate, I'm glad it was helpful.
Concise and straight to the point.

Great vid, how about a video on joining ceiling joists on the top plate? and your preferred method. :)
Thank you very much for your videos! They are great!
Hi Buildsum, Great videos and I use them a lot! (And you have helped me before).
I just had a question in regard to tie downs for floor joist on 2 storey house.
The joists are F17 KDHW 190mm x 45mm and they are sitting on steel beams with a 90mmx35mm M10 pine plate bolted to the 250mm PFC's. This is a deck area over a living area, so waterproof underneath.Would you skew nail these floor joists or just use a Pyrada connection type...or both? The engineer hasn't stipulated anything, so just Aus standard, but I can't seem to find it in the standard document?
Regards
John
Hi John
I cant find anything on this either. I would use both, if the engineer hasn't told you to use anything special then that should be heaps.
Hope this helps
Thanks Buildsum! Much appreciated.
Regards John
PS.My partner wants to know why you are called 'Buildsum'?
No problem
Ok well when i was doing my Trade my nickname was Buildsome because my last name is Bridges so Build some bridges. When i went to get my Google account i couldn't get Buildsome with out letters behind it so changed the spelling to Buildsum which sort of fits i think
Quick Question; When using the Butt Joint with Timber Cleat, How what is the recommended length for the Timber Cleat?
Hi Artemio, there is no actual length specified in AS1684, however, I would use something around 400 to 600mm long
Hey, You said 30mm on the bearer if you butt join the joists, does the lapped joint need a certain amount of timber hanging past the bearer?
Hi, no nothing is specified, as long as it is more than 30mm which it obviously would be it is fine.
Should the overlapping joists be secured to each other? Also, should they be secured to the ledger or just resting on it?
Hi Mate, at a minumum they should be nailed together and to the bearer however depending on your region and tiedown requirements greater fixings may be required.
When would you choose butt joint with cleat over butt joint? minimum bearing for joist is insufficient? It appears that these two methods are quite similar, the only different is the additional cleat
The butt joint with cleat helps to prevent the join from pulling apart in the early stages of construction when you are positioning the Bearers and Joists. A nailed Butt Joint can tend to separate if mover enough.
If the minmum bearing is insufficent the cleat is not going to make any difference you would have to have a bigger Bearer in that case.
Hope this helps
Thank you sir.
Are lappped joints best for use in the attic to lay chipboard flooring over?
Hi Mate, All methods are acceptable, it is just the amount of time that they take to construct them that make them more sutible for the given situation.
Hope this helps
When using a butt joint, what keeps them together? Are they nailed / screwed together somehow?
Hi Eddie Traditionally they used skew nails however now days practice is to put a gang-nail plate across the join
Awesome, thanks for the help
which one is the stonge joist
Hi Mate, sorry i am not familiar with that term
I asked to be shown how to join 2 floor joists together using a big dovetail joint and I got this pathetic lesson kids drawing instead
