Pinning is done with new pins.
Trying to remove them and reuse them is not going to happen as they will be too short by the time you get them out. Now the washers inside and collars around the pin Peen are reusable if you are carefully removing them. Practice pinning by buying the pin rod and washers and use a couple of popsicle sticks. This will give a good piece to play with and get the hang of removing too. Read up on this pinning and removing in our library and watch a few vids on youtube and it will work for you. But remember that this takes time to master.

One other thing I'd like to point out is the heal on your restored razor. Read up on reshaping the heal. The stabilizer is down to the same point as the edge of the razor. The edge should reach down past the stabilizer. Read up on this and you will see what I mean. This restoring can be a lot to learn. A lot more than most folks think when they start out. But with time and effort you will get it.
