Cruck Blade No 3 was showing signs of heart rot at the butt.

Image

and once debarked also of a split at the base that ran about 2 feet up the log from the base eminating from the felling hinge.

Image

It was decided to cut off 27" of butt and though this appeared to have removed the split there was still evidence of heart rot.

Image

Another 14" was removed and then 7", 7" & 7" till only half the cross section of the log appeared to be affected with heart rot.

Image

Maybe another 7 - 14" will need to be removed to reach sound timber

Image

In fact another 21" needed to be removed to get out of fungal decay affected wood.

Image

The small affected areas will be treated with preservative to kill off any remaining fungal spores and mycelium. Once the timber dries down then all fungal activity will cease but this will not restore strength to small areas of the juvenille heartwood however since a tenon will be made at the base of the cruck blade then any final remnants of heart rot remaining should be removed.
