If you decide to tackle this job, please take plenty of pictures and take notes. I'll be happy to put them all into a PDF document for you. It would make a great addition to our library.
As you get into it, post your specific questions to us here on HTF, the community will be happy to help with questions like; how do I, what is the best material, how to adjust, how does it work etc.
Let us know if you decide to do it!
