I make my own, I use one of these RDGTOOLS 2MT SOFT STUB ARBOUR BLANK END FOR LATHE 28MM X 30MM MYFORD | eBay
drill the hole through for your mandrel and 4 grub screw holes around the outside,the mandrels themselves I used silver steel,centre drilled and threaded one end.
For tools,you could buy individually, I bought a set of about 8 but only use 4, a parting tool,skew,scraper and spindle gouge.
