Hi, Tanus. Not used to seeing you here!

If you found Darrell's site, take a look at his tool making pages.
There are easy to follow directions to make tools that will help you
through the different aspects of turning. I believe with your limited
repertoire of tools you will be "up against it" if you are trying to
get walls interior walls uniform and smooth. Darrell's site offers
some solutions; make sure you don't miss his new videos.

I think you may need to accept that you will need other tools if you
want to make your turning efforts enjoyable and less difficult to
master. Whether you make them or buy them, it seems that you need
more than a couple of tools to turn both spindle and bowl orientations
on the lathe.

To the group though, I am aware that there are turners that use only
two or three tools (scrapers mostly) to do absolutely everything.
Good for them (or you).

But for me, I was never sad bought a 3/8" bowl gouge, a 3/4" roughing
tool and a 3/8" spindle gouge. Leaving my old Delta set behind (which
had tools that were neither bowl or spindle friendly) and purchasing
those three tools made lathe time real fun.

My 0.02.
