For your first hub stripping attempt you should choose a hub with a simple mechanic construction. This makes it easyer and less time consuming. A simple hub is also less expensive and for your first contact with this hobby a perfect start.
You could start with a single speed hub for example a Fichel & Sachs Torpedo or Torpedo Komet hub (both 10,- Euro). These freewheel hubs have both a coaster brake. These kind of hubs are also available from Shimano or Sturmey – Archer. So you´ll have the first contact with a freewheell mechanism and the coaster brake.
For more experienced and motivated persons I would recommend the Fichtel & Sachs Torpedo Duomatic or Automatic internal two gear hub (both 25,- Euro). The third alternative would be a used three gear hub ( 8,- Euro).
All of these hubs are easy and cheap to get from your local bike dealers. They have normally certain amount if broken or old hubs for spare part reasons. Another interesting aspect are broken hubs. To find the mechanical failure inside the hub is a quite interesting thing.
Another source is eBay! All hub versions are available and especially the older hubs for a good price!
When you have organized a hub you´ll need a bottle (100ml) of standard bicycle (2,50,- Euro) oil and a few cloth. In addition you need the necessary hub tools (depends on hub 3,- to 30,- Euro), grease for the bearings (4,- Euro) and for the coaster or rollerbrake a special high temperature grease (4,- Euro). Thats it!

Finally you need your most valuable thing time! For the first hub stripping you should be very well organized. Put all the parts which you “strip” in the correct order in front of you.
Starting with the lock nut
First step: Duomatic “stripped” into it´s major parts.
When you have the feeling to be overwelmt by the amount and complexity of parts it makes sense to make some pictures of them.
Second step: Well organized duomatic hub stripping into it´s all the parts.
I would recommend a Fichtel & Sachs Simple because itWhen you “strip” a old hub you should disassemble it into it´s major parts and clean all parts with standard bicycle oil and tabs. Use no degreaser because this would destroy the oil- and lubricating films of the different parts. A result would be a increasing mechanical wear of slide bearings.

It´s a great hobby where you directly see the result of your work. Also fascinating is to see and hear (click-clack) the different filigran parts. And get an understanding of the mechanism inside this world of pinions and catches. After a while dealing with the different internal gear hubs you understand what the engineers thoughts were and how they solved the differnt challenges of a long lasting gear hub.
