Drying Roundwood stacks before processing

[SbTVF]

25 - 30% in 6 months is amazing to hear, the wind must be really blowing through the stacks to get down to that level. Is that the average MC or tested in end grain or side of roundwood? 

Yeah it's very much perpendicular to the prevailing wind.

Thats centre grain while processing. The sub 6" diameter is lower in that moisture range obviously but I find keeping it out of the rain like that encourages the bark to dry out faster and flake off sooner particularly with sycamore which is the majority of that stack.

The ease of rolling it up makes it worth doing if no rain is forecast for a while particularly in summer.

If you don't mind me asking how many tonnes do you buy each year ? what I can see in the photo is several hundred tonnes alone!

 

I think I will go with your covering based on how you have found it. How many seasons could it last if we take care with it?

As you know I do contract processing and get to see others storage. The dryest roundwood I have processed was covered on the top and was sat upon very free draining ground. I am sure the later was very advantageous and I am seeing with our crate storage how the dryness of the base makes a difference to drying times.

That interesting - I use large bearers, and orientate to take account of wind direction. A good sheeting job is essential. The larger diameters will always be a challenge and 1 season will never be enough of course. Others have found more like 4 for around 350mm - 450 dependant on species. If you have the capital it's a good investment as it reduces the heavy investment on  IBCs.

I don't mean just the bearers but the ground below. I process for two places on mine waste in the Tamar valley. The ground is very free draining gravel and the wood drys out well on both sites but better on the one that gets covered. Ours sadly sit on bearers on a muddy field

Wow, that's uncanny. I would have thought my 12" gap under the stacks would be perfect. I know some do cross bearers also, then I could have 2ft gap under the stack. I could also screen out some stone so just hardcore under stacks. A bit to think about then. ?

Not suggesting bearers are not a good thing just dry ground beneath helps a lot as well.

I can get approx 250t on the left and 150t on the right. The right is currently chip wood for the boiler but we have got 100t+ of new storage area courtesy of the neighbour directly opposite our entrance so I'm hoping for an extra 100t of hardwood this year.

That's a 25K investment although I expect once you have built up to that level of stock held it gets forgotten about providing you keep stock held at that level.

Drying in this manner is certainly to be applauded and can be sustained for the long term.

 

How long do your breathable covers last and what width do you generally buy?

Yes very much so, the money is set aside for it and just keeps rolling round into it for the most part. Apart from out of log season when I'm cutting away and having more deliveres but very little sold of course.

There's thousands set aside in bags too and 100 IBC'S but it's the only way to keep up with the rush come autumn.

The first one we bought is on the left stack. It's 2 years old and doesn't look a day older than the newest that arrived last week. I'm expecting 5 years at least from them.

I've only been able to get hold of 4m wide stuff. All our roundwood is in 3m lengths anyway. Don't think extra overhang would be beneficial in the least.
