This post gives a detailed description, with photos and reference to a Parts Diagram, of how to replace a Dyson Slim DC18 Undercarriage. The Undercarriage would require changing if part of it broke since parts cannot be obtained individually. I changed mine when the Air Input Changeover Valve Actuator broke.
“Since I first published this article, in February 2013, I have had plenty of feedback from readers and I have gleaned information from statistical data which has encouraged me to improve it. So if you came here soon after I published it you should find better information now. You will also find some photos of repairs carried out by readers of this post in Step 10.” — Helpful Colin
“Happy New Year! In 2012 I resolve to lose weight (again).”
Well I resolved to lose weight every year since at least 2005 and some years I succeeded. One tool I require for this is a spreadsheet to accurately record of my weight. I use Excel for this and I’ve produced some Excel Body Weight Templates for making new sheets annually.
I record my weight on a DAILY, yes DAILY, basis. I know all those slimming clubs advise against measuring weight daily but to me that is unscientific. High definition pictures are better than low definition ones and weighing every day gives a good weight definition. Anyone would think that the act of measuring weight caused it to change. (I know Quantum Physicists have their doubts.)
Being scientific requires not just the measurements written down somewhere but a graph to give a picture of what is happening over time. I want to see if my weight is actually heading down or up or staying put. During this time I have come down from my heaviest of 15st (95.25kgs) in 2005 and again in July 2007 to 13st 4lbs (84.36kgs) in the same year. Then I rose again to 14st 7lbs (92kgs) and came down to 13st 2lbs (83.46kgs) in February 2010. Now I have risen again to 14st (88.9kgs) a weight I swore I would never see again.
(Note to self: I need to be more scientific about regulating the calories I consume.)
For me as a Microsoft Excel user for many years, Excel was my tool of choice for recording and plotting the data. The rest of this post explains my method for collecting the data and the use of Excel Body Weight Templates to start a new record annually. Ultimately it offers Excel Body Weight Templates – files that you can download to use with your Excel software so you can record your measurements in like manner.
Having decided on the tool for recording the data I then had to decide when I would measure my weight. I chose first thing in the morning, before eating or drinking, after visiting the bathroom and without clothing (I keep my hat specs on). This way I get the feel-good-factor of seeing my lowest possible weight each day. (We lose up to 1.5kgs at night due to exhaling moisture in our breath and urinating.) The point here is not to come up with an exact daily weight – it’s impossible. Our weight fluctuates up and down 2 or 3 pounds throughout the day. The point is to try and arrive at a consistent set of measurements that can be used to display a meaningful average weight situation, over time, on a graph.
