I'm pleased to say that work on renovating the Adana 8X5 hot foil press is now nearly complete.

Adana Hot Foil RestorationMany thanks to Mike Jacobs, an expert in the hot foil process, for contacting me outside the forum with some excellent advice.

I noticed this brass type on Ebay, which is most suitable for hot foil, bit beyond my price range, though!
