New Shed with Shiplap cladding

[stevieob]

Guys

I'm undertaking a task to build a new shed and clad it with some shiplap cladding. I actually plan on doing 2 sheds, but the first one will be small enough and will be the test project before I contemplate the real buid!

So I plan to have a pressure treated frame covered with some 9mm OSB3 and will put the cladding over that (well, will probably stick some sort of waterproof membrance between them). The shiplap that I think I am buying will be 144*18mm (maybe 22mm). The first section I will be doing will be narrow enough at only 750mm.

My ideal finish would be to try and screw the cladding in discretely so that the fixings are hidden with a 25mm galvenised screw through the shiplap, OSB and into the frame. Is it a good idea to hide the fixings between the laps or could it risk the wood splitting and not giving a tight secure fix? Or would it be better to have the cladding screwed in with 35mm screws and going through the centre of the board?

One or 2 screws on each side? Do you think there is any need to fix at a centrepoint, I'm not so sure as they are only 750mm wide

Would appreciate your opinions please

Why not use a Nail gun or staple gun? (Compressor type)

Loads of vids and websites on installing shiplap. Suggestion would be follow the normal way of installing. I tried to be smart with installing my cladding and although I managed it how I wanted it was a total pita. If shiplap is normally single nailed in the middle then do that.
