Thread: Where to buy 1/2" (NOT 12mm) MDF in Melbourne

Bismar

If you cannot find 1/2 inch MDF, would it be possible to put a 0.7mm backing sheet behind the 12mm MDF to raise it to the right height for your CNC router?

Cheers

Graeme


PS: Have you checked that 12mm is actually 12mm and not 1/2inch MDF rebadged?

Is 0.7mm a common size that i would be able to get from bunnings?

As for checking the sizes, nope, I'm assuming they are 12mm. Which is a fair assumption as all the others are in mm, and that we are in Australia.

You could in fact apply some veneer....and arrive at your required dimension, or you could make some adjustments to the plans manually. Otherwise ask a board manufacturer to supply 1/2 sheets, which they will. You just have to look farther afield than Bunnings.

The only time I purchased 1/2" MDF in North America it measured out to 12.0 mm.

Reminds me of trying to find a metric round-over bit which I finally found. The package arrived sporting a 6.35 mm (1/4" translated) label.

I just checked three pieces of "12 mm" MDF in my Australian garage. The median thickness was 12.28 mm with a range from 12.21 to 12.36 mm. Swiss dial indicator, calibrated.

An offcut with one layer of thin laminex and one layer of veneer measured 12.82mm

There may be unlocking software available for the CAD files - but yes, the half inch may in fact be 12mm (shhhh...the US uses a lot of metric sizes they just don't admit it!)

Thanks for your reply and suggestions, i'll make sure i bring a ruler to bunnings on my next visit, and probably get some cheap veneer.

Do you know the actual thickness of 3, 4, and 6mm MDF? You might be able to laminate to 12mm
