I turn flutes in 3/4 , 7/8 and 1"...I rout two pieces and glue them together to achieve the bore....Then I put the hollow 1 1/2" blank onto a mandrel and turn it round....Sometimes I need to put it back into the lathe for just a little bit and and want another method beside the mandrel...Mandrel works great but I am going to use a jamb chuck on the headstock (just a block of wood on a faceplate with turned down steps) but I need something simple for tailstock end.....Also if I didnt rout quite deep enough and I am a little undersize I can split the thin flute when I put it back on the mandrel....So I just need something simple on the tailstock end to hold the flute for sanding , putting burnlines etc. I have begun boring some but still do some this way.... Thanks !!
