Summary

At the time I made this I was 'into pallet projects'. Of course I waited too long to buy something decent for my wife, so I had to make something.
I don't remember how I came up with this idea, but it was a good idea.

With two runners of a pallet, I made a block of wood, which I then roughly shaped with a hand saw. Then I used an angle grinder with a sand paper attachment to shape the heart.

Lastly I used a soldering iron to engrave the design (but a laser tool would have been easier :-)

My wife got all emotional when she got this gift.
