Burning wood chips

The briquette machines extrude the chips under extreme pressure - It is the lignin in the wood chips & sawdust that acts as a binder to hold everything together. The pressure used is what causes the lignin to stick.

You just won't get the pressure required from a manual press to get the lignin to stick, so you'll need to add a binder. Either PVA or cement plus a bit of sawdust to fill the gaps. Only a small amount of binder+liquid is needed. The hand operated paper briquette presses are not really worth the time or money - Way to flimsy, and you just can't get a high enough pressure to get anything to stick reliably.... Yes, I have tried.

If I have another go at making briquettes, I might try a hydraulic press - Perhaps make something that can be fitted to the log splitter.

Good idea. A "mechanics" hydraulic press can be purchased at modest cost.

I would be inclined to dry them out thoroughly, then use them as kindling.

I thought about that and will indeed use some for kindling. It's just the large volume I have means I was searching for a way to make more use of them.
