If you were making cabinets from MDF how would you make the joints ?

I've used biscuits with satisfactory results. Dowels would also work ok but harder to align without a decent doweling jig.

 

[Steve Maskery]

It depends.
If the outsides were not seen (as in Kitchen cupboards) pocket hole screws are a good solution. Biscuits are invisible and also excellent.

yere like steve says the kreg pocket hole system is brilliant. but if you can get one the domino is pretty sweet.

Just as an alternative, I always run grooves if I am making kitchen or large cabinets. This may be a bit of an overkill but just like the strength you get doing it this way.

Just built some boxes using bisuits and seems good so far

biscuits. If you want to screw into the end of MDF putting a dowl in at right angles to the direction of screwing to give the screw something to bit on works really well.

I used biscuits and Titebond for my kitchen cabinets without problems.

I've used both dowels and biscuits for MDF kitchen doors.

As said, a decent dowel jig is essential whereas using biscuits you just need a routed slot. PVA but not Cascamite though. The Cascamite seems to soak in and lose grip whatever thickness you use. The only time its not my preferred glue.

All of the above but just to let you know...Titebond and a pingun makes super joints too...I use it all the time for jigs. I use biscuits for more permanent jobs.

I like to house the shelves in slightly this helps to stop the mdf splitting when you glue and screw it and supports them better too.

Doors I use biscuits
Cabinets cams and dowels.
All the best

The same for me
The same setup on the spindle does the groove and the tongue it also is good for drawers
I can do two sides and the top and bottom of a cabinet in a couple of minutes just add glue and finished
