more than I really wanted to get the free shipping ... but it's all stuff
I'm going to need , so I went ahead .
Among the items I got was a 5X5 milling vise . It's really a bit too big ,
but I'm sure that I'll need the capacity eventually . Also got some
parallels , a clamp kit , and an edge finder . Already got a decent
assortment of calipers , mikes , and dial indicators .
The next major need is going to be rotary indexing , and I'm a bit baffled
. Spin indexers , rotary tables , index wheels , what's good for which task
? I expect to cut a few gears (some for the lathe , couple are missing
teeth) and maybe a drive pulley for a cog belt (Harley final drive belt) .
Be nice to be able to index and drill or mill a bolt circle ... or mill an
eccentric slot for a cam .
So , what do I need , and how big ? I'm kinda thinking a 4" or maybe a 6"
rotary table ? I'm a bit leery of going too big , this thing doesn't have
quite the spindle/table distance (18" max) a full sized knee mill has .
Another question , I have been reading up on hobbing gears . I have a
keyed mandrel , apparently used by a former owner of my lathe to drive a
1/8" slitting saw . The shank is 3/4" diameter where the collet (or holder)
grips and 1" at the end the hobs would mount , about 4" overall length . I'm
concerned about rigidity and flex in the cutter . Should I be ?
