Earlier in the year I had the chance to use a powered jointer at the local woodwork club so I cut up a bunch of hardwood stock I had sitting around into breadboard sized lengths and used the machine to get the edges ready. The one shown in this post is Jarrah and was originally a decking board.
I used biscuits to join them, and this is where I have photos from. In the first image the board has been glued up but not sanded and is very rough. You can also see the glue spillout in the joints.
I cleaned up the joints with a card scraper, then I used a combination of my scrub plane, jointer plane and a belt sander to make sure everything was nice and flat. I then sanded it to 1200 grit manually. I also rounded the edges with a block plane at this point.
I gave it three coats of canola oil, which is food safe since it’s a cooking oil, buffing each coat in with a cloth.
Finally, here it is with the first loaf of bread on it ready to be cut. It’s been in use nearly 6 months now and is holding up really well. Jarrah is a tough wood so barely scratches when the knife touches it, and it’s held up nice and flat even without breadboard ends being used.
