hi guys,
i'm trying to experiment with cutting some rattle profiles (.75" hard maple with two 1/8" layers glued on top - total thickness roughly 1.25")
i overlooked some important details on the first run, feeds and speeds were waaay off, pass depth was too deep, and i snapped my .25" downcut bit right off.
i'm new to this and would eventually like to use double sided machining to dish out the skinny mid section, but for now, just trying to dial in feeds and speeds for the profile cut.
attaching pics of my results, up until the bit broke, as well as a finished rattle. don't have an indexer, which i'd imagine would make turning a rounder rattle like this easier, but have been playing with roundover bits to achieve something similar for the time being.
if anyone has recommendations on proper feeds and speeds for cutting 1.25" maple, i'm waiting on another .25" downcut and hope to cut again soon, this time with a little more success
the rattles are roughly 6" long, and about 1.75" wide at the widest point.
thanks,
