That is weird, a faulty bit of ply maybe, like there’s a gap in one of the layers?
Maybe, it’s been fine for seven years though!
Indoor or out?
May want to check if the building air flow has changed in some way
General woodworking question - I need to cut some holes in the side of an deck, about 3mm wide, 10mm across and 20mm deep. I tried drilling a bunch of holes to the same depth and then trying to keep drilling to ‘connect’ them together but it’s not very accurate. What would be the best tool to achieve this? Here’s my first attempt in the side of a small piece of a deck
Like a biscuit cutter, but small.
Maybe a dremel with one of these

Router I reckon
Thats a job for a router 
it’s a great excuse to get a fairly inexpensive tool, tht youll end up using all the time for loads of cool things.
What are you doing with the deck.
Some ingenious clamping.
A normal router, you’re asking to take some fingertips off. I have a mini plunge base for a dremel which would work nicely but you still have have a load of clamps to keep everything steady.
I’m sure you could jig up a drill as a makeshift pillar drill to save buying new tools
I bought a router as I absolutely 100% needed one for myriad jobs, both pending and upcoming, around the house.
Needless to say, it’s still boxed, unused in the loft after 8 years.
But I still remember the intense rush of dopamine I got when buying one so might go out and get a backup one just in case.

Thanks all, never used a router or a dremel this is all pretty new to me. Putting the wood in a vice and then using a dremel with the thing Keithbeef posted, with a standard 3mm drill bit seems like the easiest option. I’m struggling to see what attachment I’d have to use for a router. Or can you just use drill bits on those as well?
A router bit would be a nightmare even with a bearing guide . A drill bit will be more controlled and direct for you , will just take longer . Router can be uncontrollable on such a thin piece of wood unless you have the right jigs set up.
If you knew your kit and jigs the best tool wold be a festool domino cutter but that’s getting proper nerd tech level.
Might have to ask for a Dremel from Santa
Don’t specifically need one but will come in handy one day, surely?

Definitely.
I use the tiny cutting disks & sanding drums all the time for ‘stuff’.
Hi @Pocalyptix ,
I’m going to do the same for my kids this summer. Did you come to a conclusion on the best deck make up for outdoors?
Was it OSB base layer, with WPB? Or birch ply as @Chopper suggested?
I see that Jewson do a moisture resistant MDF that looks very similar to Skatelite, its called “CaberMDF Pro FSC Moisture Resistant”. Has anybody had any experience with this?
I can see that you used a 4ft board for the flat, but what radius did you use for the 2ft ramp?
Any help would be greatly appreciated.
Cheers n gone
Your cutters are the wrong size spanky.
