John,
Bad news on the short time working.
Think positive though, you are very fortunate in that it could have been a 0 day week.
It is no joke being off work for any length of time. Getting extra hours in the shop at this time will be a bonus, but after a time that will start to wear off.
I haven't been able to work for over 5 years now, and you have to strike a balance between the shop as a working environment, and then for true enjoyment. It could easily become a place you hate, if you don't get that balance right.
Look for a project that you always really wanted to do, but never had the time before now, and if it is within your financial means, get stuck in.
John
