Hello. I have a bbq which is half grill and half hotplate. Looking to get a second hotplate and get rid of the grill part but cant find a hot plate that'll fit. The current size of the grill is 460mm x 220 mm. Same as the hotplate. A maximum of 470 mm by 450 mm hole exists. The only plate I can find would result in a loss of 5 cm. That's alot of realestate on a small bbq. Surely I don't need to to just buy a new bbq... Has anyone got a custom stainless steel plate cut and bent to a custom shape?
