The place to come to share your technical expertise, or just find out what the little springy thing is that's just pinged out of sight under the work-bench.
I've found it out for you and I've sent it to your email address. Let me know if you've received it ok. I'm not to good when it comes to PDF formats. Bit of a numpty in that field.
Bit of advice. Buy a good bed and a good pair of shoes, because if you aren't in one you'll be in the other.
