Here is a list of resources and tools that will come in handy if you're undertaking a bevel project.
Web Sites/Mail List
Ducati Meccanica has a ton of information on older Ducatis, including electronic copies of manuals and other documentation. There is also a section listing parts suppliers. Since they have done a good job of listing all this stuff, I won't repeat it here. This is also the place to go if you want to sign up to the "Bevelheads" mailing list. The group includes some very knowledgeable people, and most anything you're going to try has been done by someone there already.
If you are interested in single cylinder Ducatis, one book you should have is "Ducati Singles, First Person" by Tom Bailey. It's easily the best singles book I've read, wih first hand knowledge of the bikes and the "scene" in the US back when these bikes were new. You can get it from Amazon, but do Tom a favor and cut out the middleman. Contact him at the e-mail address shown above for more info. I'm sure he'd even sign it for you!
The parts manuals for the most of the single cylinder bikes are still available and also very useful. The exploded views come in handy during the rebuild, and having the correct part numbers when you order parts saves a lot of time. It's also a good way to see if a previous owner has changed something around on you, though beware, no book is the final source on what is correct for your bike. There seem to be exceptions to most everything when it comes to what came on what. In some ways, I think the parts books are more usefull than the shop manuals!
There is one restoration book for Ducati Singles that I know of. Honestly I don't refer to it all that often... it does have some good details and is helpful, but it's not intended to be a shop manual so you'll still need one of those.
I suspect that the singles are similar to the twins, in that there a few tools that you pretty much have to have to rebuild them. This is a partial listI came up with for my roundcase - I'll revise it as I get into the engine work.
Exhaust Nut Spanner - DO NOT try to get the exhaust ring off with a hammer and punch, You WILL break the fin off. Trust me! Some people have had success using a strap wrench on this nut, I tried with a brand new wrench and pulled the strap apart before the nut came loose. Once I had the correct tool, removal was trivial. Buy the tool, a new exhaust nut costs about as much. Note that the smaller singles use a differnt tool than the larger singles. Also, the larger singles can use the same tool as the twin cylinder bikes.
Piston stop. You need to know where top dead center is to time the cams and ignition. This is a simple tool that makes finding TDC pretty easy. I made one using a spark plug and a 3/8" aluminum rod.
Degree wheel. Once you've found TDC you need to time the cam and ignition for each cylinder in relation to it. I bought mine from Vee Two in Australia. Not cheap, and it's got an error in the markings, but it's handy once you have it. Phil carries these.
