Step 12 - Let us know how it goes.  I'll fix up whatever boo boo's you find and offer it to the FAQ ghouds.  It sounds like these cylinders are somewhat prone to breakage.  Unfortunately, I don't know when they changed over to the new parts, so if anyone wants to know which rev they have, they'll have to look.  If there's interest I'll post a pic of the old style hook shaft (broken) to my lameo web page for comparison.
