Advice appreciated
I recently bought some macrocarpa (cypress) planks from a mill in Gippsland and had them shipped to Canberra with the intention of making outdoor furniture. The planks are 2.6m long, 200 wide and 50 and 38mm thick. The planks were cut to my request, and I know nothing about how long since the source tree has been cut. The weather here has been hot in the fortnight since they arrived - in the thirties and up to 39 degrees. i have stored the timber with stickers in the shade and with a plastic sheet over the stack. I also painted the ends. The moisture content is around 20%, which I thought was too high to start using.
I now notice that longitudinal splits have appeared - see photos. i don't know how far these penetrate.
I think i have two options to prevent this worsening. One is to keep the pile damp until cooler weather arrives, but this could be a couple of months, will delay my ability to use it, and could even cause mould.
The other is to cut it up into smaller pieces and hope that relieves the stresses that are causing the splits.
i'd be happy to receive opinions as to these options or any others.
Thanks

Local mill here mills lots of Marcocarpa and I’ve transported lots of it and that is a common feature of the cypress.
Probably 60 percent of the cypress I’ve carted ends up at primary schools and park grounds for outdoor uses in playgrounds etc with the rest to private properties for outdoor entertaining areas and community gardens for planter boxes and garden edging. Most of it gets left as is, so that it ends up with the silvery patina.
This company uses it quite extensively and has a gallery showing its various uses in their designs.

Can you both tell me the names of the saw mills (gippsland and east warburton?) - I'd love to buy some green slabs to directly from a mill

There is a mill in Hastings (Mornington Peninsula) that tend to do sleepers, but they can cut to order.

At this time of year fast drying is going to be a problem. Particularly when timber is moved from one location to another. Your Canberra summer is harsh and the cracking will be inevitable. Best place for it would be indoors, out of the weather, until things cool down and there is more moisture in the air.
I never mill in summer.

Plastic sheet over your stack is likely to cause it to cook. Your best bet is to put a layer of dry or sacrificial wood on top, then some bearers around 100mm plus high, then some roofing iron on top weighted down. You want the dry or low value wood + airspace to keep heat away from your good boards. Then use hessian sheeting (potato bags) on the upwind side of the stack and wet the bags down thoroughly of a morning... it'll keep a cool damp breeze flowing across the wood which will slow moisture loss.
On the bright side if you've got it down to 20% without anything but end splits you'll do okay. (Hopefully.) What happens is the checks and splits form at high moisture levels as microchecks and then as the moisture content drops away they become visible to the eye, which many mistakenly think is a drying fault occuring at lower moisture levels. Below 20% you can dry them hard and fast with no issues provided they had no issues develop getting to that 20%.
