1485828 2022-04-28 22:44:00 I am in need of some 4mm thick plywood to finish a woodworking project.

I did have a suitable piece originally, but due to storage in poor conditions over years it has gone moldy, and had to be torn off anyway as the screws were rusted.
(Half did come out OK and I got one with pliers, but the remaining two don't want to budge. One is stripped and the other has no head.)

In any case, I need a new piece of plywood.

But the thinnest I can see in Bunnings, Mitre10 etc, is 7mm.

Routing a deeper recess for that would be 'tricky' due to the two rusted screws still in place, so ideally a 4mm piece would be best.
Then I guess I can just shear those two screws off and leave them there.

Does anyone know where to buy some 4mm thick plywood?
I don't need a huge amount, only about 950x450mm.

Bunnings have 1200 x 600 panels which would be great, but alas, only 7mm.

If you google 4mm Plywood NZ you'll come up with answers like www.plyman.co.nz

Maybe someplace like a cabinet maker ? Of course it may cost you a arm and a leg .

Does it HAVE to be Plywood ??

Could it be MDF as thinline comes in 3.5mm I think

1485832 2022-04-30 11:35:00 Check it out as Caravan ply; if you go for B/BB grade, it is fairly reasonably priced (For these days!) Otherwise Bison board or hardboard. R2x1 (4628)
1485833 2022-04-30 21:00:00 Thanks everyone, I'll look into it.

Would prefer plywood or other with an actual grain, as this will be oiled or varnished, not painted.

Yes it's a backing board thing but will still get seen from time to time. So I'd rather not have MDF.

Given the apparent hassle though, I'm starting to wonder if I can clean up the original piece and glue the splits back together...

1485835 2022-05-08 01:21:00 I actually managed to clean up and fix the original piece pretty well. The only problem is the two bad screws left in the cabinet.

Not that I need to remove them, I could install new ones alongside, they're in the back and won't be seen hardly, although it still bothers me a little.

Thanks, I did try vice grips on the one that I could reach, but they just slip off when I try to turn it. The head already broke off as it was severely rusted.

The other does have a head but is in a recessed corner and there's no room to grab it with anything.
