Bracing

[MattyF]

"Blow-outs" typically due to lack of maintenance, poor placement, wrong materials, or wrong installation. Oak is an excellent compartmentalizer, in North America anyway.

 

If a species can wall off big invasive pruning cuts, little drill holes are not a problem.

It's not the drilling holes that's the problem it is the tannin eating the metal ... Screw bolts are a big no ... I've seen English oak and chestnut blow out cables on many occasions... Evasive bracing is not really practiced much any way here any more.... Have to say it works great with beech though!

Zinc-coated metal like EHS cable resists corrosion--materials! With through-cabling, only that cable is exposed to tannins and other corrosive compounds. I agree that lag bolts seem inferior, to through-cabling, in most cases.
