Topic tags/keywords: lathe question turning

I’ve recently returned to woodturning and have ‘roughed-out’ several very green pieces, bagged them, and their now sitting under my bed for drying.

Question…can anyone recommend what the moisture content should be for final turning?

I usually try for under 10 percent.

Many people will tell you to buy a scale to weight your bowl blanks weekly until they stop losing weight before final turning. Idea here is when wood stops losing weight it is at EMC therefore ready to turn. (see below) That works great but advise buying an inexpensive moisture meter like this one. Bought this meter couple years back when Lowes sold them for $10.00 and seems to work great.

With a moisture meter you know MC before start turning, after rough turning, and before final turning. Without going into great detail want wood plus or minus 1 or 2 percent in use EMC (equilibrium moisture content). EMC will differ for indoor or outdoor use.

That’s exactly the information I was looking for. Many had simply said ‘bag and wait’, which while I’m sure will work it doesn’t fit with my OCD nature. I need something I can ‘measure’ before and against…this will work.
