As I’m going to be resawing air-dried timber, I thought it was a good idea to get a moisture meter so I can figure out how much I can expect the resawn boards to move, as the moisture content in the middle of the beam will be higher than the edges.
There are a bajillion different makes and models but the main decision is whether to buy a meter with or without pins. The ones with pins are much cheaper but only read the moisture content where the pins are inserted. The pinless ones are crazy expensive but measure moisture quite far beneath the surface. Seeing as this is my first one and I didn’t want to shell out too much, I went for a model with pins. Here’s the link to the particular one I got: http://www.amazon.co.uk/gp/product/B003CSNV2Q
It arrived today and I’ve been measuring moisture in every piece of timber in the shop (including the shop itself!). Readings change slightly depending on the orientation of the meter relative to the grain direction, depth of pins in the wood, and whether you’re measuring end or long grain. They’re all pretty close, though.
Time will tell if it’s a valuable tool. It’ll be interesting to see how the moisture content of the redwood I buy drops when I bring it into the shop. Once the readings stabilise, the timber shouldn’t move much more.
Does anyone else use one of these?
