try a better material , there are some metal rose arches well over a hundred years old that are still doing good service

barkershill yes and there are other metal 100 year old objects that have rusted away. It's about how you look after things.

Good point. There are quite a few wooden stave churches in Norway, Sweden, Denmark, etc that are hundreds of years old. (Centuries, plural!) From around 1200 AD.
They are set up off the ground on stone footings.

It looks like they used a Japanese wood treatment technique called shou sugi ban. The wood is scorched, which then resists rotting, pests, UV light, etc. (But I think the churches were sealed with pitch? I’m not sure on the details – I just found out about this recently).
And you can use these construction methods without needing access to a forge, with (free) materials found right on your own property.

No picture of finish project. How disappointing.

Love at first sight.

HAWT is a very accurate description.

Nice hair she's pretty as a picture.

not if the wood is cut in the winter and treated. Hazel hurdles can last 15 to 20 years if looked after properly. The longevity of the product depends on how the customer cares for it.

You could fire harden the wood once the arch is built, should give it a few extra years. Its a japanese technique called shou sugi ban, some wooden japanese temples are over 1000 years old and were built using this technique.

Alright mate, fancy seeing you here.
