I need to replace some screws on a 30 year old Yamaha Piano. They are on hinges on the lid so quite visible. They are brass counter-sunk with a small Phillips head. 4 x 1/2 are far too big so presumably looking for a no. 3 or even a no. 2 gauge. They are fairly readily available slotted but...

I have recently fitted a Nordan Window. Beautifully made of pine, clad in aluminium to reduce maintenance in my impending dotage. The inside is factory finished with Azko Nobel XV600 semi-gloss water based clear lacquer. I will be fitting an internal window cill and have a length of (very...

Unless the timber is already treated it seems we have a choice of applying preservative by brush/spray or dipping (and then use best construction techniques). My idea is to try to use a relatively simple method to increase the efficacy of dipping. If only time permitted I guess I should...

Thanks Robin. Some useful suggestions there. However, I haven't painted exterior joinery in 20 years. I much prefer stains. As for timber I don't have the luxury of buying profiles I need other than in Baltic Redwood and I certainly don't have the time to produce them myself from DF, Larch etc...

Thanks for the suggestion. I am pretty well acquainted with the principles of vac-vac preservation but creating the vacuum on my proposed set-up is another time-consuming step.

I have some windows to make. I am contemplating acquiring a couple of metres of 160mm underground pipe and fitting a fixed cap on one end and a screw-on cap on the other. Then I will insert the window components, cover with clear preservative (25l bulk-buy), screw on the cap and apply a low...

What width do you need ?

I'm happy to 'round' the tops of 19 x 100 fencing slats with a jig-saw. 20, 30, maybe 50 at a go. But how would you go about rounding upwards of 500 pieces ?

He might be happy, but he is out of touch with the regulations and putting lives at risk.

Delighted you are asking these questions. You never know, we might save a life. An intumescent seal expands and prevents the passage of flame. A smoke seal expands and prevents the passage of smoke. You might see two seals on a frame. If they appear the same they are probably both...

I wasn't suggesting you join, I was merely using their website information as a short-cut to understanding the regulations. Unfortunately many building inspectors are not fully up to date with current standards. The lack of knowledge regarding fire safety is frightening. An earlier poster...

FD20 no longer exists

In that case, the door-set will certainly not reach FD30 requirements and lives will be put at risk.

Not correct. During a fire-test a stop is not (theoretically) even required ! The stop is on the non-fire side of the door. The intumescent seal prevents the fire reaching the stop. Remember, a fire-door alone does not make a fire door-set. The idea that stops had to be thicker and/or made...

Why thicker stops ?

The green colouring is a dye and it indicates that the board is Moisture Resistant. It may show as a thin line or over the whole thickness depending upon the manufacturer. However, because the green colour can show through finishes MR board is also produced without any colouring at all. The...

Howdens stock a range of AWO veneered archs, skirts and door-frames

A good and useful suggestion Andy, but I would be concerned about any swelling or contraction of the pole making it loose or tight within the tube. The practicality is the pole and standard will be stored in a house and taken out occasionally where they could become wet or even very wet. The...

Thanks once again for your advice. Pren is correct when he describes the stress this joint has to take. It is even greater when the holder of the flag is travelling on horseback at a full canter !! The dowel screw idea would work but I don't think it will be strong enough. Looks as if I'll...
