Amateur Turning issues
Hey guys I’m having an issue with my lathe only just started using it and I’m not sure if the problem is speed, dodgy tools or just the type of wood it’s just treated pine and it’s coming out really rough any ideas? Much appreciated Brent

I'd say a combination of timber and tool sharpness.
are you practising? Hence using treated pine? Are you masking up?

Yeah the tools I found at an op shop and probably arnt the best quality I have sharpened them but the angles may be incorrect as I just copied what the last person had done. I might get a decent set of tools and some quality wood and give it a go.
Fumbler what is it I am supposed to mask up?

I think most things have been covered.
Tools need to be sharp.
Presentation of the tool to the wood.
Type of wood.
Direction of cut cutting down hill rather than up against the grain.
What tools are you trying to use on this piece do you have a photo of them.
If you can get the above points sorted then turning becomes a pleasure. and as stated try joining a club or find a turner close by who is willing to show you what you are doing wrong

If you did the finished part on the extreme right of the piece in the photo, keep doing that. That is how it is supposed to look. If the rough part is done with a roughing gouge on half rotten timber, that is normal. Get it down to round then use a skew and spindle gouge.
As above, get some instruction on sharpening and use of tools. An hour of instruction will save 10 - 20 hours of experimentation and trial and error.So much timber, so little time.

The following is just in way of some explanation... the best advice has already been given; find a tame woodturner to spend an hour or three with you and show you the ropes. A little demonstration beats words, words, words hands down!
As has also already been said, Pine really isn't the best timber to begin with. (Treated is even less so, for health reasons.)
When I was teaching young turners I generally started 'em with pieces of 4x4 KDHW fence post and didn't introduce 'em to pine until they were feeling cocky and needed a reminder of reality...
At first glance I'd guess that you've turned the rough area with a gouge... in scraper mode. Meaning only the cutting edge is touching the timber. No matter how sharp the gouge is, it'll tend to tear out the grain like that because the cutting angles are wrong. Way too shallow.
Instead, the bevel should be rubbing; One approach to learn this is to angle the tool upwards on the tool rest and lower the tip until the middle of the bevel makes contact with the blank. Then slowly lower the tip, keeping the bevel rubbing, until it starts to cut. So, the end of the handle should be lower than the tool rest with the tool pointing slightly upwards when cutting.
(Of course, my guess could easily be wrong. )
Scrapers are different and only the cutting edge touches the blank, with the end of the handle higher than the tool rest and the tool pointing downwards when cutting. But a scraper's bevel is at a much larger angle, generally closer to 70-80° than a gouge's 45°.
Here's a fair guide to desired angles per tool types. This is a guide, not gospel: most turners adjust 'em to suit themselves.

Hmm, I reckon stick with the pine. When you have mastered the pine two things will have occurred
[1] you will have a better knowledge than most on how to sharpen, whats a good angle for you and when to sharpen
[2] You will have developed skills and knowledge of woodturning that will stay with you for life
In other words, you will be a damn good turner. Pine is disliked by most turners as its soft and prone to tear out, demands good technique and razor-sharp tools.Inspiration exists, but it has to find you working. — Pablo Picasso

This is very true, but may cause a beginner to give up prematurely because of discouragement. I started with bowls on a 7 X 12 inch Chinese metal lathe, with a sharpened screwdriver and bench chisel. Several lathes and many tools later I was having difficulties with the Accursed Skew. With the encouragement of Retired and 20 hours in front of the lathe with the skew, I now make a tool handle for entertainment, out of everything from 100 year old Black Locust fence posts to Southern Yellow Pine.
The secret seems to be about 20 hours in front of the lathe, 1 - 2 hours at a time. Assuming some instruction so you are using proper technique.So much timber, so little time.

Be VERY CAREFUL of treated pine.
Im not sure what precautions you need, but its nasty stuff, especially if you are inhale, or the dust is going in your eyes.
And make sure you wash your hands afterwards.
I would go so far as to say, its probably better not to use treated pine. Turning it releases all sort of nasties for example Copper, Chromium and Arsenic treatment.
