A P/T is the bedrock of any workshop. You may plane one board by hand but how enthusiastic will you be tackling a few cubic feet.
Since I started woodworking about 18 months ago, I've been hand planing all my rough stock using a 5 1/2 jack plane to get one flat reference face before running it through a benchtop thicknesser to get a flat and parallel opposing face. I use the "
hybrid milling" approach advocated by the Renaissance Woodworker, basically spot planing to only remove the high points identified with winding sticks and a long straight edge, etc. Once the board rests flat on the bench with no rock then it's good for the thicknesser. I think this approach has a lot going for it, especially for people just starting out, for those with limited working space, or for those who prefer to do more of their woodwork by hand.
I live in the tropics and use exclusively local hardwoods, which are often very dense and abrasive. I also try to use as much reclaimed timber as possible and the boards are usually quite warped/cupped/bowed. So the milling process can be time consuming but I've learned a lot about how wood works and have got progressively much more efficient. I make furniture and smaller decorative items (boxes, frames, etc.), so don't have to contend with milling a few cubic metres/feet at a time. If I was a carpenter/joiner then I guess this wouldn't be a viable approach.
I can't quite understand the logic of benchtop thicknessers - the brush motors must put the neighbours on edge as well as the operator,
I use an Axminster
AT330ST benchtop machine. It screams! Thankfully the neighbours have been accomodating. But the spiral cutterblock leaves a super nice finish, even on very hard and figured woods. I have recently ordered a stationary
combined P/T - with a helical head - which should obselete the benchtop machine and will (I hope) be considerably quieter. But I have no regrets about starting out this way. Incidentally, and probably quite controversially, Chris Schwarz wrote an article a while back in Popular Woodworking in which he suggested that "
portable planers are better". One point he made was that the univeral (brushed) motors used in portable benchtop machines spin the cutterhead much faster than the induction motors in the bigger stationary machines (i.e. 8,000-10,000 rpm vs ~5000 rpm). Why does this matter? He asserts that: "In general, faster cutterheads leave a better finish. With a fast cutterhead, each knife takes a smaller bite, reducing the chance of tear-out". I'd be interested to hear people's take on his arguments...
