I found this rotten bit of wood under my lathe that I`d forgotten about,can`t remember where it came from,or what wood it is,it was so soft I had to put a 2" coachbolt (head cut off) in my screwchuck before I found a bit of solid enough wood to hold it,then roughed the outside,bit of a job where all the bits were sticking out(in photo),got it round eventually and carefully,the tool kept trying to drag into the soft bits(real fun that),ptu a chucking point on it,but again awkward,as wood only on 3 out of 4 jaws,so had to hang 2 over edges,the get a bit of grip,but not to hard as one side really really soft,flooded it with superglue in the end and left a spotlight on the area for 1/2 an hour to cook it,was able to get it in the chuck after that and start hollowing the bowl out,couldn`t put the speed up beyond 250 RPM as when I looked closer it was 3 or 4 branches/roots joined together.The wood was really soft on about a third of it,the other two thirds were intermitantly soft/firm,the soft side in the end I had to flood it with superglue which ran out(over half a bottle used,then a third of a bottle(the little glass ones from Liberon)of sanding sealer,that stopped chucks flying off,but still very soft and delicate,so left it a chunky bowl as I didn`t want it to explode all over me and the workshop.
