Hit a minor problem this afternoon that I've not seen mentioned before, while thicknessing lots of shortish pieces of oak. The chip extraction is far from perfect, and on some later pieces, I managed to "snowplough" some chips under the front edge of the wood as I fed them in. This effectively raised the front of the timber, so it got thinned too much over the first several inches. Would not matter so much on longer lengths, but it's worth watching out that you are feeding the timber in precisely along the line of the thicknesser table so you sweep the chips out of the way.
