DON'T LEAVE THAT CROWBAR HANGING LIKE THAT !!!!!!! .
Ouch!famous last words , till it lands blade down on some ones toes. As happened to me many years ago when some one left a crowbar hanging on the header plate of some studwork !
If you can find them, 312’s may help next time you’ve dis similar metals.Used my best (whatever I could find 316 rods), works for me.
Always done it like that.
What do you dislike ?
I'm not a pro, oh no...
Yeah my bad. One of those days309 is what I would use, well if I have any at the time, if not 316 is what I use, usually have them
I think, and I am saying, think. 312 is usually for higher alloy steels rather than mild steels but...Yeah my bad. One of those days
15 metres of valley gutter in 4 sections. Press brake getting some use recently which is good, I've hardly touched the thing since I re tooled it!

I am pleased you’ve found something.One of the happiest day of my life.
First day as apprentice in a machine shop.
I was like child at Legoland
Gantry cranes,lathes,radial arm drill, Bridgeport style mill drill,horizontal milling machines, surface grinders, honing machines, slotting machines,power hacksaw, hydraulic bandsaw, mig ,stick,Tig welders , cutting torches.
That's a dream.
I've done so many things today , working , learning and trying to give everything I could.
Employees and employers happy of me and of my approach to work.
Look , think, ask get done.
Example I know they will soon need a tool ,I ask I they need it , and take it where it's needed.
They made me use a oxy propane torch to cut a dozer blade , and they said me that I wouldn't have much to wait prior to start using a lathe (under their supervision because I've never used one)
Essentially I got to say , today was a good day (cit.)

NOOOOOOO!!!!!!If your allowed to pics would be cool but alot of places don't like that
NOOOOOOO!!!!!!
Don't get the reputation of a youth of today, always on his phone, this early into the job . . .
Bloke next to you might be okay, but the three down the other end of the shop, seeing the phone out . . .
Thanks to @Lewis_RX8 and his lathe thread I have been converted to powerfeeding, only had my lathe 6 years! I set it at 0.092mm/R, the lowest my gears will go. It wasnt anywhere near a mirror finish but probably the smoothest and most consistent I have done on en3b mild. It looks rough but cant feel it.
1mm DoC and 700 rpm. Followed by a 0.05mm dia. pass to get on size. More testing needed..
I know these inserts dont like bigger DoC so swapped a Pramet dcmt. All my packets show 0.1mm/r feed as the minimum so swapped the gears to that. This test was 0.8mm DoC/1.6 dia. Mirror but rougher than the moon. A few more passes and got the roughness down.
Some deflection without the center so needed another very light cut, this is the result before parting.

The problem with these deeper cuts is you hit your final size well before you finish testing!
Too lazy to swap belt for high speed but I think it will be much better at 2200 rpm, but thats still well below half the rated SFM for most inserts on 25mm bar
