A few weeks ago I had to repair a garden bench for a customer.
Three of the slats had rotted and needed replacing, the other two were fine so they were left. I replaced them with oak, so I know that they'll last a long time.
That night when I got home and told my wife what I'd been doing that morning, she asked if I thought it was viable to do the repair. With my time doing the repair, sourcing the the oak, cutting and planing it to size and picking it up from the mill I should imagine that there will be little change out of a ton (I was there to do other jobs as well).
Now I know you can go down to B&Q or a garden centre and pick up a bench for much less than a hundred pounds but in my experience they don't last more and a couple of years before they fall to pieces.
Instead this customer had invested that money into their old bench to make it last much longer than that. Maybe in a few years I'll have to go and replace the other two slats but I'm sure that, in much the same way as triggers broom, this bench will last for a very long time and cost a lot less than buying imported benches and replacing them every few years.
We could do with some garden benches here on our little homestead but I'm reluctant to buy the ones mentioned above, so I think I'll start looking out for second hand ones in antique shops and in the paper so that I can buy one that can be easily repaired and made to last forever!
