What length nails for 18mm architrave?

[phatboy]

I am likely to buy a second fix nailer for attaching a load of architrave and door stop. What length nails would be recommended for 18mm architrave and 12.5mm door stop? 38mm seems to be considerably cheaper than 45mm, so I wonder if the 38mm is sufficient

Thanks!

how thick is the architrave at the front edge where it will be attached ??
i assume between 5-12mm then yes

18mm I think. It is flat with just a chamfer on the edge towards the door. So the nail will go through the part that is 18mm thick.

ok you are attaching architrave set back say 6mm on a say 32-38mm frame so your fixings will be 12-16mm from the front edge what thickness are the architraves 12-16mm from the nose ??

It's 18mm I think.

This is the profile I have, but with the chamfer being smaller:-

Thanks!

I generally use 44 or 50mm for most things unless there is a chance of hitting wiring or pipework beneath - better pull-out characteristics than shorter pins

There used to be a rule of thumb that said 2.5 times the thickness being nailed. 1.5 the thickness being screwed to get the length of fixing.

38mm should be ok, with a nailer you can easily whack in extra nails.

Even though it means extra holes to fill

I usually go for overall length of triple the thickness, due to too many problems otherwise. I looked that rule up online.
You can always use one of the no more nails type things for insurance. I used it to hold fully finished skirtings to a really rough wall and it's actually held well.
Are you sure the shorter nails aren't thinner as well? I just worry you'll end up returning with the longer nailer anyway, at your own cost.

I removed my architrave, previous owner had used around 50 pins per side and each was made up of up to 4 pieces , guess he didn't like to have any waste.

FFS!

He was also a bit over zealous with the power sockets 17 in the lounge and 21 in the kitchen [and none matched].

You only have enough sockets when you're not using any multi way adaptors! Although 17 doubles? Does seem high.
