No problems Erewhon, I understand that it does take some time to get your head around situations such as yours. I lost my job just a little over 4 years ago when I came down with Positional Vertigo (PV) I was off for 3 months when I received a call from the boss at work, he said, put in for a separation package because there is no work here when you get better. It took a number of days for me to realise what this meant to my future. At 61 years old at the time, it threw all of my retirement plans into oblivion. Once I had managed to come to terms with this, I applied and was accepted for the package. Sensibly, I used the money to pay the house off and make myself debt free, then I applied for welfare from the government. No worries there, but I had to do so many hours volunteer work each week to get my payment. This is why I am volunteering at the Willo's Men's Shed. I now only have 2 months left to go before I officially retire (65 years old) and I will continue with the shed as it has been a God send to me. I have helped a lot of people such as yourself come to terms with what ails them. This is by working with them to show them alternative work methods and most importantly, listening to them. There are around 70 members in the shed and they all have a tale to tell and demons to master, but the members never judge one another, this in itself is all part of the accepting and healing process.
I wish you all the best as you try to get your head into focus with your PD. You have already started by asking the right questions and getting back with this forum.
The only advice I can give you right now is, use whatever guards and safety precautions are available on your machinery, this will lessen the risk of personal injury by hiding the dangerous parts of your machines.
