Not cheep. £450 for them both, that including all the work plus freight costs.
I don't have a full breakdown of the various charges however as you can see more has been spent on the Audax. Worth it though, both frames needed re-preservation, in the case of the bottom brackets on the tandem quite urgently.
I love the job done on the Audax, I now have something quite unique with a finish that I'm confident will last through quite a number of winters.
The wife's due home from work at around 1530 so at that point I might go and get started in the garage.
