The corner of a shelf is cracked after accidentally dropping on a tile

how can I fix this? Should I cut off the broken end and use wood
filler and
sand to original shape or is there a better way?

G'day MC,
I can't figure out your pic. I can see the damage, but the shelf
construction has me buggered. Is this MDF sheeting sandwiching a frame?
If the groove, channel is not important, just cut the corner of and glue
another piece of mdf in it's place, Shape and sand and finish and it
will be almost invisible.

After seeing the pics of the broken pin I now can see the problem.
If the surface of the MDF isn't damaged to badly, this may work.
1. Obtain a piece of timber the same thickness as the groove.
2. Wrap this piece in wax paper or glad wrap.
3. Squirt heaps of PVA into the cracks and splits
4. Tap the wrapped piece of timber into the groove.
5. Place a clamp on the outside, squeezing the shoulders against the
wrapped timber.
When reassembling the unit, place the repaired section so that it is in
an inconspicuous place, if the repair does not become invisible.

If the actual surface is damaged I'd have to go with the suggestion in
the previous post. Still use a wrapped piece of timber so that the
groove remains the correct width.

Good Luck
John
