I recently bought a De Vere 504, the free-standing floor model. In order to get it out of that basement and into mine, I had to take it apart. Disassembly was not as obvious as one might think and I now have no idea how to get it back together. When I took the column off the base, the top gear drives fell down into the base. I had to take the covers off the chain assembly and now I have no clue where everything goes. I bought a manual but it was not of much use in getting it back together. Don't tell me I am an idiot since I already know that. Help!
