Down here in Australia our bricks are cored, (hollowed out), so its best to drill into the mortor for a solid fix, Never had issues doing it that way. 👍
Cheers m8, seems like it was builders night out the previous evening? Had a few pints with the mad lads. Great and informative, we will be using your methods here on our patio!
Thanks for the video. I have to say that I tried, very hard, to follow your advice but it didn't work for me. I drilled the batten I wanted to fix to the wall, as you describe. I'm using 100mm, no. 10 Thunderbolts. I then used a 150mm x 8mm masonry bit, purchased for the job, to drill into the wall. I spent over an hour trying to wind the bolts in, to no avail. I ended up using a shorter 10mm masonry bit to widen the holes and was finally able to get the thing fixed. It's tight and certainly not going anywhere but I'll be using 10mm in both the wood and wall from now on.
Thanks for your message. Really sorry you had a problem with the job. I probably need to explain clearer on the video but i did suggest to use the m8 bolt and linked them in the description, to make sure youve got the right tools for the job. The confusing part is that the m8 bolts are actually 10mm wide and require an 8mm drill bit. You used m10 bolts which are actually 12mm and require a 10mm drill bit, so tgats why you struggled. Wish i could go back and explain this in the video but im glad you got there in the end. If you or anyone else have problems with any of the tutorials on my channel, please message me here and i will get back usually within the hour.
@@JamesMontana ah! That makes sense. It did seem sensible that you'd need a smaller wall hole for the bolt to grip but I should have checked. Thanks for your reply.
I’m glad you’re not the only one as I used a 8mm drill bit but M10 bolts as I thought that’s what was being used in the video, but this explains it a lot!
To be fair i have had lots of practice. The key is to over compensate the depth of the hole for the bolt and blowing out the dust. These thundebolts dont drive in otherwise, but they do give an incedibly tight hold. Thanks for your comment !
Hello sir,am I right in saying if you get 10mm thunderbolts you need to use a 8mm masonry drill bit and how deep do you need to drip as I don’t want to go through into the house.Cracking video
Hi sir. Yes it is a little confusing but you need an 8mm drill bit for m8 bolts. 10mm drill bit for m10 bolts and so on. Youll need to over drill by 20mm. If youre fitting 100mm bolts you will need at least a 120mm drill bit. You wont go through into the house as house walls are double skin. All materials needed are linked in the description box. Good luck with it 👍
I had to fix a timber fence post to a concrete post - one of the scenarios you cover in this video. I bought all the right stuff and a new masonry bit. I had problems hammer drilling into the concrete - after a short distance the bit refused to go any further. I therefore tried drilling in different places on the post and finally managed to secure the post using four masonry screws at the right depth. I mentioned this to my neighbour who has experience of this sort of work and he said that there is metal mesh inside the posts and that I had probably been hitting it. Is this true and if so maybe you should mention it in your otherwise excellent demo. Could I have perhaps have tried using a drill bit for steel when hitting mesh ? Thanks
It works very well, but with a smaller drill bit, my bolt was 10mm and when used a 10mm drill bit the hole was too big and it didn't work, so used a 9mm drill bit with the 10mm bolt and works like magic, very secure to the wall. Hope this can help anyone!
The smart thing to do is to not attach anything to the house. Instead, install your last post a foot or two away from the house (so you can dig a hole and not hit the foundation) and run the fence rails over to the house. This makes the fence freestanding. Once you start modifying the customer's house you open yourself to all kinds of troubles. Whenever I build a fence I make it a rule that I don't make any holes in the home. My fences always float an inch away from the siding or brick. If I have to attach to the house and there's no way around it, my price reflects the added risk.
Planning on helping a friend to install a gate at the side of his house and this video is just perfect, honestly this is brilliant! Can I ask a question? What size thunderbolt would you use if the gate post is 4 X 4?
Thanks mate. You need a M8 150mm thunder bolt. Use at least 4 for a 6ft high gate. More the merrier. Now you can impress your mate with you gate hanging skills 👍. Good luck with it
@@JamesMontana actually (sorry)...if I countersink the bolt as you do, I'm going to lose around 10mm of length, am I at risk of blowing out the other side of the brick?
@@meganmurray9122 it could potentially. Youd need to drill as far from the holes as you can. Start off with a small drill bit and work up to the required size.
Thanks for posting - really well explained and shot. Can I ask what do you do if you start a concrete post fence from a wall - bolt it and concrete it or just concrete close as you can to the wall ? Any issues with bridging damp course etc ?
I would just bolt it. Youre going to really struggle digging a hole right next to a house because of the foundations. Just get yourself some 150mm concrete screws and that will be plenty solid enough 👌 you wont get any damp problems at all. Just drill your bottom hole above the damp proof course.
Hi, this is very helpful. I would like to do the same but with an 7x7mm wooden pole. Should I aim for longer bolts? How deep would you like ideally recommend the bolt to be in the brick?
Thankyou for your comment. Glad you found it helpful. Yes definitely use longer screws. Most brick is around 12cm thick. A 250mm screw would do perfectly 👍
Because the bolt is actually 10mm wide. It only needs to glide through the timber, but you need to drill the brickwork narrower, so the screw can grip onto the brickwork. I hope this makes sence.
Nice dog! Thanks for the video, I like the style and its very informative! Looking for some specific advice please - I am installing 3ft trellis fence on top of my 3.5 ft boundary concrete wall. My wall is in an worn condition but structurally seems ok, thickness of 150mm. I am in a windy location. Due to a pipe I have discovered running underground parallel to my wall I cannot set my posts in the ground, so my plan is to attach fence posts to wall face with the trellis hovering above it. I have just had delivery of my 4x4 posts and I didn't realise how heavy they would be so slightly concerned, awaiting trellis delivery. I cannot find any specific advise online, are 4x4 posts when attaching to wall face overkill and am I better off getting 3x3? Thanks
Thankyou. Yes 4x4 posts are a little overkill but it will be fine. As long as to have at least a double skin wall and the bricks arent loose that you are drilling into. 150mm concrete screws. 3 each post should do it. Walls are stronger than you think.
@@JamesMontana Wow thanks for the quick response! Looking forward to building it this weekend. The underground pipe adjacent to wall is about 150mm below ground, is a combination of setting the post at that depth with concrete and attaching to wall face with concrete screws something to consider?
Hey mate great vid, going into detail about each size bit is so helpful. I'm trying to do similar this but having issue. Using a 8mm thunderbolt I've drilled a hole with a 6mm bit but I can't get the thunderbolt push in as I drill and using a 7mm bit the thunderbolt goes in and seems to take but it doesn't take much to loosen it and pull out. Same with 6mm TB AND 4 & 5 mm bits
Hi Tom, Im glad it has sort of helped you lol. But yeah it can get confusing with the sizes but its pretty simple. If youre using M8 bolts you need an 8mm drill bit. M10 you need 10mm and so on. you need to over drill the hole to 20mm deeper than the length of screw you are using, or you will struggle getting it in all the way. Hope this has cleared things up a bit for you. James
