The Margaret of Antioch dials are over twice that size. I wonder whether Brookbrae could still do a job that big. If so, they may have a customer!< I don't know. There have been changes at Brookbrae over the years. Earlier in this thread John Davis referred to an enameller that he used and I seem to remember that it used them at least partially because they were one of only a few who could accommodate the size of dial that he then had in mind. I am sure that he will read this and will explain the issues. I am actually unsure of the needs of the technology here because the problem is supposed to be the paucity of ovens of a size that can take the metal bases. However in a very extended restoration of a vintage car (it's 42 years since I last drove it!! ), some years ago I needed to get some replacement mudguards repainted. I then discovered that the originals had been stove enamelled and in trying to be authentic I have found no difficulty in getting that done first with a matt-grey priming enamelled layer and later with a gloss one. Are the ovens used for stove enamelling car parts (the ovensI used for my mudguards were of a walk-in size) the same sort as those used for artistic and enamelled signs etc? I have heard that stove enamelling needs a higher temperature than powder coating It would be nice to know if a combination of the two technologies can be used to solve the problem you have.
