I want to use a larger DE handle for some of the older 2 piece Gem and Ever Ready SE razors where the head comes off. To accomplish this I just need a threaded post to insert into a DE handle. I just need to know where to get one of the right post diameter and thread size. I guess I may or may not have to use some kind of adhesive to secure the threaded post but it may hold the razor head firm without it. Any suggestions?
