Diamond file is good for rounding the vertical edge

Diamond file is good for rounding thd vertical edge. 1/4″ sq tools are a lot easier to grind and plenty stiff enough for small cuts whilst learning

On Howard Lewis Said:

Cutter? Surely lathes have tools and toolbits and milling machines have cutters? The difference being cutters rotate while tools and toolbits remain stationary? (Not sure where that leaves shapers though?)

While most of us are trying help a newbie, can the above please be moved to pedants corner.

Pedagogy not pedantry! Teaching a “newbie” incorrect terminology is not helpful in the long run.

While there different lathe brands than yours is Chris, a couple of PDF links for good basic turning information including tool sharpening.

If you have lots of books and don’t yet have this one, put it on your mandatory to buy list. https://www.teepublishing.co.uk/books/in-your-workshop/model-engineers-workshop-manual/ Yes I’d term it as a medium level to sometimes lower advanced level book. But it’s one you’ll refer to often. And even at your current level, a great deal in it that can be used immediately. The authors thoughts about proper slide adjustments, HSS tools, and even the pros and cons of QCTP’s just for starters. I was going back through my own copy this morning in fact.

As someone has already said in this thread, problem solving is a big part of the hobby. Sometimes highly satisfying, and sometimes extremely frustrating until you finally get a reason and solution figured out. Learn to view any problem using pure logic and think everything through. And not what you think might or should be true. In the beginning it usually isn’t. 😀

My old-British books call lathe tools “knives”…

History left metal-working terminology in a mess, especially in pioneering Britain, where trades, regions and companies all had their own variations.  Whatever jargon individuals were taught in the past can’t be universally correct because there is no common standard.

I think beginners just need to be aware it’s necessary to read between the lines sometimes.  We shouldn’t make it difficult on the forum:  I suggest ‘cutter’ is easier to understand than ‘tool’ because ‘tool’ is ambiguous, whilst “knife” is positively misleading.

DID THE PERSON UNDERSTAND WHAT WAS MEANT BY THE TERM ? Does a lathe tool not cut ? It should ! Noel.
