    Default Deck handrail post

    Hey just seeing what is the best way to attach handrail posts to joists. Should you notch it onto them or just leave them full? Also would 2 m12 bolts be ok?
    Cheers

    hardwood or softwood?

    im notching the 90x90 merbau posts by 15-20mm, and using 2 x M12 bolts, plus some blocking to stabilise the joist laterally...

    i am going to paint the cut area with bitumen paint too...

    Will be soft wood mate. Yeah was thinking 20mm notch. Just wanted to see what other people do. Was even thinking 4 bolts. Joists r in hangers so 2 through bearer and post and 2 back through joist and post?

    Notch and two bolts is fine. Put a piece of blocking in between the joists and batten screw through that into post as well. Prime and paint all checkouts and assemble the joint wet.

    maybe if it is a high balcony you'd need the 4 bolts?

    Its only around 1.8 off the ground so not that high mate. Was worried off putting 4 bolts would be too many holes in post maybe?

    Two is fine. Up to you whether you bolt through the bearer or joist. Whichever will give you the desired outcome.

    Yeah right no worries. I might have to put 4 in the corner ones to tie it together and make it strong. I think u suggested it before with the post between 2 joists.

    Yep, corner posts are different when carrying a perimeter joist.

    Ah ok so would you go say 2 bolts top end of post through the bearer and 2 bolts through bottom end through the joist? Knowing my luck i would hit one of them so placement is crucial lol

    Ok, so if you squared 4 lines around the post over a vertical,distance of 150 mm. The lines from the bottom of the post (with the post flush with the bottom of the bearer) would be 30, 60,90, 120 mm. These are where your bolts go. So on the bearer face mark up from the bottom (or down from the top) 30 and 90 mm. On the end joist mark 60 and 120 from either top or bottom, however you measured on the bearer. Mark the outline of the post on the outside faces of joist and bearer and mark a vertical centre line. Move off the centre line about 15 mm and mark your drilling positions on the 30,60,90&120. Use an auger bit, hold the drill square in both directions and go for it.

    Enjoy. Remember, you only get one shot with the auger. You can't straighten it. Take your time, use a small square if you have to. Trade tools sell long series auger bits cheap
