were these taken at different points on the tree?

 

graphs 1 & 3 are the same drill, yes?

 

graph 2 looks to be a completely different volume of wood.

 

 

 

The blue graph shows the penetration rate of the resistance of the needle through the wood & the green graph (usually shown behind the blue, though you can switch that around) shows the torgue of the needle.

Hi

Yes there all on the same tree, oak.

There at different locations around the tree, which does a large cavity.

 

I was on speed 3. Yes sorry 1 and 3 are the same, upload twice

 

It may just be the fact there's a lot of decay?

1 & 3 (which present as identical drills) show that there is largely intact functional wood (apart from the dip from 14 cm to 20 cm which may be a pocket of decay)

 

Where as the second drill shows almost no resistance (so decayed wood volume) from about 5 cm inward. A vast difference in the functional outer sapwood areas between the two/three graphs.

 

 

As long as the needle chisel is sharp, setting 3 should be OK for oak.
