I am currently renovating our staircase. It has not been painted in 38 years, fortunately it is in amazing condition.
It has taken four coats of primer / undercoat but I am very happy how it is looking.
My question relates to replacing the newel cap (the top of the newel post) before finishing.
Currently it has three round tops but I want to replace them with flat newel caps.
I am wanting advice on removing the existing caps. I have been told that it is unlikely to be screwed but was actually turned as part of the post.
Any advice on removal would be appreciated. Thank you.
