When I picked up the local machine I realized that the bottom of the case was split and would need to be repaired. I began working on the case bit by bit.
You can see the split on the bottom of the case on the left side of the picture. The split went all the way across the bottom. As I have acquired more machines (I think that might be another post in the future.) I have discovered that many cases need restoration as they have suffered water damage sitting in damp basements. Mr. Dreamy even bought a machine where the bottom and the lower edges of the case were missing and eaten away by carpenter ants??? termites???)
The next step was to remove the vinyl covering.This was easy, as Mr. Dreamy divulged the secret. The cover is glued on with animal hide glue. (Post about hide glue is here.) This glue is water soluble and readily softens with warm water. I had a large roasting pan that I placed on the stove. I heated the watered and dipped the parts of the case, one side at a time, into the water for a few moments, then peeled a bit of the covering off. Dunk, peel, repeat.
