    Why is there a large cement line joining to extension?

    I thought toothing in was frowned upon now as the movement of the extension is likely to be different to that of the original house, causing toothing in to create a stress point resulting in cracking? Or am I talking nonsense?

    "Cheat" gravel/stepping stone path - worth a try, or bound-to-fail-madness?

    The only gotcha will be if the slabs sit on the grid they effectively only have the depth of the gravel size to stop them slipping. I have done it, and it works, but you do get some movement with the slabs.

    Is this really a tonne bag?

    FWIW when I ordered a tonne bag of gravel I got a similar sized bag but pretty much full to the top.

    Is this really a tonne bag?

    If the circumference is 314cm and it is cylindrical then yes, the volume is 0.463m3 and you will have about 741Kg of gravel (dry) or 889Kg if wet

    Is this really a tonne bag?

    30L is 0.03m3. So you could fit approx 33.3 buckets in a 1m3 bag, so approx 1620Kg. Making the 1600Kg above seem the correct value to use. The volume of a cylinder is the base time height, so (pi)*r2*height, or 0.425^2 * 3.14 * 0.59 = 0.33m3 of gravel, if a cylinder.

    Is this really a tonne bag?

    A cylinder of radius 0.425 will have less in that if it was a cube of 0.85 x 0.75, assuming same height.

    Is this really a tonne bag?

    Wet weights 120% of dry according to some random bloke on the internet. If we put that with the measurements given by the two slightly less random people on this thread we get 674kg. And wet gravel.

    Is this really a tonne bag?

    If those measurements are correct and a cubic meter weight 1600kg you have got about 561kg of gravel. But is the 1600kg dry gravel or wet gravel? If dry then wet it would be significantly more and therefore you would have more than 561 in the bag. So wait till it rains and feel better about things.

    Constructing an insulated door

    You can also get the fire door blanks MDF faced for painting, but they seem to be much more expensive.

    Constructing an insulated door

    Yes. The edges need to be relipped if external or if you don't want to spend hours filling and sanding. I have used these in the past https://sheetmaterialswholesale.co.uk/plywood-door-blank-fire-door-44-x-915-x-2134mm-fd30/

    Constructing an insulated door

    You can get oversized fire doors that you can cut to size. Not insulated as such, but better than a normal door.

    Router, bench and saw advice

    You can normally get an after market compatible router attachment for the tracks too, so you can use them as a guide for the router. I have not tried this yet, but love my track saw!

    Fitting flush hinges

    Yeah, my research has just showen me the type you are more familiar with! Like I said, new to all this! This has helped though, allowed me to think more clearly around the issue. I think I need to make the gap the size of the knuckle, then because the leaf is centered and has a thickness of...

    Fitting flush hinges

    I'm not sure I understand that? This is similar ito what I am basically fitting. The flush hinge is not offset like some, so when flat both leafs are join at the center of the knuckle and lie in the same plane. The key is trying to get them exactly centered in the gap so the door is flush to the...

    Okay, so just slide another hinge between the knuckle and the door to get consistency? Thanks for your help!

    Fitting flush hinges

    Side mounted. I think. They go on the edges of the door (which is 44mm thick) and are not recessed.

    Moving a hinge on a wooden door

    Hi, I have built a set of bifold doors. Each door is effectively a fire door weighing around 30kg. I have used a set of large flush hinges approx 100 x 70 and three per door. They work, but the finish on the hinge is not great so I want to replace them. Am I safe move the hinge say half a hinge...

    New roof joists on brick shed

    Ok, great. One other question; the joists are running perpendicular to the fall of the roof. With the metal roof this is achieved by a change in the height of the joists across the roof. If I want to change to timber I guess I will want more contact with the joists so this might not work? If...
