Antique Ox Tongue Iron Restoration

In this video i m restoring an antique oxtongue iron. The oxtongue iron is named for the particular shape of the insert. It was used in the late 19th century. I bought this one on eBay for 25. The condition of this item was not too bad in terms of rust. Unfortunately the oxtongue insert was missing. The handle had play because one nut of the two bolts was missing. During the dissasembling I realized that it had asbestos as termal isolation, I replaced it with parts made out of duroplastic. Duroplastic
