I have sold my CB 3200 and ordered a used reconditioned Adler 69. The 3200 was a great machine but just not what I needed. The 69 has a lot smaller dia. cyl. I will post some pictures when i receive it and get it mounted on a table that I am making for it. My question to anyone using this machine do you run a 138 thread top and bottom or a 138 on top with a 92 on the bottom.
