That's put me in mind of Jack's last project in our workshop.
Prior to this he had made clocks and ukuleles.
A neighbour saw how well our garden chairs' restoration had worked and asked him to restore their knackered bench. Jack was unable to do much other than rip down the Sapele boards into batons for the job before he got ill and I finished it for him.
We used Green Hammerite and it really enhanced the cast iron sides. I think we used yacht varnish to finish the Sapele. All of the bolts, washers and nuts are stainless steel.
