I wonder do you have anything like the "Men's Sheds" we have here in Australia?

These are sheds or workshops set up in the community where non-working men can get together. They can hammer in a nail or work on a project; they can teach some-one else to hammer in a nail or help some-one else with their project, or they can go there just to interact socially, even if they're not interested in any type of project at all.

They've proven to be an excellent way of getting men out of the house, and have saved the sanity of many wives.

Sounds like your DH might be an ideal candidate for a program similar to this.
