Thanks guys. Man, I'm a bit confused now. Might try getting a 3/8" bowl gouge and see how I go. I have a grinder which I can use to sharpen the tools. Although someone suggested using a stone as the grinder takes too much off but that seems a little slow – less time to actually turn anything.
I can't do much at the mo' as my freelance work (furloughed, atm) has gone a bit crazy and it's my eldest's birthday party (ZOOM) which is a Harry Potter theme and I'm sorting all the stuff for that.
Maybe next week.
I will look at the 3/8" BG though. And do I need a roughing gouge, for really uneven or blocky things?
BTW, thank you all for helping. And the chap offering to flog an old set. I will PM you now, just to see want you want for it.
