Had to cut down a maple tree after it caused me to replace a water line. Stacked the logs on pallet where they have sat for about 18 months. I milled a couple of 12” sections and it was spalted. It is solid, not soft. My question is how long until a log stored outside reaches a moisture content at which it can be used? Having been stacked outside for that time would the internal moisture be reduced sufficiently so as the risk of splitting is less likely when brought indoors and cut into small boards?

Here’s a couple of pics of a couple of pieces

Air dry depends on the climate. In my zone that’s 12-16%.

You’ll need to get it down to 8%, again, depending on climate, this may require a kiln.

Risk of insect damage is higher with air dried, kiln dying addresses this issue.

I’ve had the experience of borer holes emerging in wood 2 years after installing in a house.

Logs will rot (spalting is the beginning of rot) before “drying”. You have it backwards – the wood is more likely to split left whole, less likely if cut into boards.

I also turn wood on a lathe. I turn it wet then let it dry.

You should mill those logs as soon as you can. Boards will dry much faster than logs. Logs will check and rot and the longer you wait the more wood will be wasted due to checking.

It will dry quicker and better if sawn into boards.
You want to do two things:
1) control the drying – so paint the end grain with latex or wax emulsion.. anything to seal the end grain to slow moisture escaping out of the end so quickly – you want it to dry evenly out of the side grain.
2) control the tension created. So if you saw it into boards, you’ve eliminated a big part of tension created when a log is dried – ie. the circumference and the center are losing water at the same rate, so when the larger circumference shrinks, it tends to develops tension and splits.

Good luck and have fun. That’s some really pretty wood.

I appreciate everyone’s advise. It’s clear I was way off base stacking logs and thinking it will dry. I will saw it and put it up in my shop.

The spalted was a nice surprise.

Thanks Dan
