There are articles and FAQ topics here that can assist you in understanding your hobber.
If you have questions after reading the DIY suggestions there, please offer your questions here.
One question I'm hearing is that you are wondering if the machine can cut helicals, even without a differential. I would say no if there are no feed change gears to control table feed.
Some machines use hydraulic feed control, and these are not suitable for helical cutting (if they don't have a differential).
If it has feed change gears then it is likely you can find sets of index and feed change gears that would cut helical. This is described in a topic in the FAQ.
Does anyone know the index constant for his machine? The Stankos shown in the FAQ all have a 24:1 index ratio, based on the information I've been able to gather...
