Not knowing too much about the beasties, any suggestions on a suitable pneumatic nailer?

Options seem to be cheap - Ryobi Airwave 3 In 1 Air Brad Nailer And Stapler | Bunnings Warehouse (I'm not a fan of buying cheap and then buying again, and I'm unsure of the modern ryobi build)

vs Something like this DeWalt - DeWalt 12-65mm C Series 16ga Precision Point Air Nailer Bradder DPN1664PPXJ | Total Tools

Bunnings do the bostich range, who I think make some of the DeWalt stuff too?

Application would be mostly nailing ply and mdf panels at this stage

Bostitch is fine,I have several. Most important thing is oil them every time you plug the air in and don’t go overboard on air pressure or you flog the big rubber bumper out inside.

I have a Makita 23g cordless pin nailer - great for aligning but will not hold. I also bought a cheap Brad nailer ($59?) because I bought a cheap Aldi Ferris compressor ($60) and wasn’t sure it would drive a Brad nailer, which it does, and it has been working fine with heavy use. As RB said, oil it before use.
I have an Ozito stapler/brad nailer but, as mentioned, it leaves an ugly mark when firing nails.

I need a shelf high up in my new garage to store things like coolers, buckets, sports gear and other odds and sods, so this thread is has come along at the right time. I just have a problem imagining a 600mm deep torsion box is going to be able to hang on when loaded. Being mounted high if it fails it's going to be ugly.

I note Chris's sewing desk has support panels at the end even if the drawers aren't adding support.

Anybody go pics of a real installation of a similar high floating wall mounted torsion box? All I'm finding by google are narrower bookshelves. Maybe I've misunderstood the application and Bernmc intends to mount the box on supports not just have it hanging off the wall? A torsion box might span better between fewer supports than simple planks on angle brackets?

It won't be floating - it will be supported by very robust ply sandwich-type shelf brackets at 450mm intervals. I've used these for my wood rack, and hung my 70kg herculean body off each to test them. So the shelf just needs to stay intact in between each bracket.

I have thee Bostich pneumatic nailers, all have been very reliable over the past 35 years. I bought a little Ryobi stapler for occasional use 2 years ago and have been pleasantly surprised at how well it works. Not as ruggedly built as the Bostich machines, but it hasn't missed a beat.

In that case why make a torsion box? Some yellow tongue flooring would be my choice.

Trying to avoid another trailer-borrowing from the big green shed!
