Wanted to check how others check mc on slabs or any lumber that you only can get the meter (delmhorst j 2000) on top slab? I've got a load of 9/4 poplar in kiln now, its still dripping some. The top slab show around 8% this morning but I can't get the meter on any one below it. I'm not sure how to make sure the middle ones are close to that also without unloading the kiln. Would sticking in the end of the slab work?
Just checking to see how others might do this?
I think if it is still dripping water you have slabs wetter than 8% I would let it run till it quits getting water .
The ends do not work unless they have two coats of AnchorSeal from the start of drying. The edge will work with 2" insulated needles like Delmhorst makes.
It was dripping very slow last night so I cut off the DH and ran the heat up to 150°. This not the first time I could not test lower slabs so I'll check all the slabs when I unload them and maybe get a better idea for the future.
When you run the heat up, it is best to remove the dh unit, as the seals do not like the heat in the simple dh units.
I've got a Nyle, kind of hard removing it.

That's the way, test the slabs as you unpack, as well as the same with 4/4. Then get an idea of the drying pattern of or wet spots in your kiln. All the boards should be within a certain range. If not, try to make adjustments to the kiln baffling, airflow, or other to get them there for future loads. Most times, the dryer boards are toward the top, so unsticker and test, and when you hit a unacceptable moisture level, put the remaining pack back and cook it some more.
I took them out today and top one was 8°. The next 3 was between 17-22° so back into the kiln. It's dripping real slow, so I'll give it a few days and see how they do. Next time I stack heavy slabs I'm going to try loading them so I can my mm on middle ones.
Next build... Lumber rotisserie...
Sounds like an air flow issue
