Novice question Re lathe
Fergus OMore:
Bradley and most of the good authors demand a 'wee sporran spanner' :hammer:
The bit about using a felt tip is 'me' or someone that I've forgotten :doh:
If you want to do a series of 'competences', I'd reckon that Advanced Machine Tool Work by A H Smith is as good as any and free on the net. It would probably cost you more for ink and paper than something secondhand from perhaps Amazon, to down load. I gave my copy of Smith away to another newcomer- so sorry.
What you will find is that buying castings now prohibits making tool grinders, cheaper to buy a 6" one and kit it out properly. Others will disagree which is their prerogative!
Meantime, regards
Norman

pictures of your set up's ect would help us narrow down whats going wrong ;-)

I will take some pic's and upload them, thank you.
kwackers:
My experience of starting out was trying to turn a piece of old steel with one of the carbide tips I got free with my Chinese lathe. It looked as if the dog had chewed it, disappointing wasn't the word, I thought I'd wasted my cash.
Someone recommended I tried using insert type tools so I bought one on the basis that it was at least one less thing to get wrong. The difference was amazing, my machine was cutting properly, with little effort and the finish was pretty good (and that was just eyeballing the tool height).
Can't say I've ever looked back, I've since learned to sharpen HSS for those times when one off 'form' tools are required but most of my turning is with tipped tools.
Among other things they don't seem as fussy about center height, I've deliberately tried moving them above and below to see what effect they have but find they need to be significantly off before the finish starts to suffer (size of work dependent). This is even true of my tipped parting tool, only once have I had parting go wrong and that was because I was running the lathe the wrong way! (I still got half way through the bar thinking that the tool had gone blunt before the cut threw the tip out of the holder!)
Bit long winded, but overall if you reduce the number of things that can be wrong it's much easier to find out what is...
