Better not let Tzed see the size of boring bar your using!!!! I was using one about that size and could not keep chatter down. So I made a 3/4" one, now it cuts real nice.
Randy's must be stiffer than yours:msp_w00t:

You should have been an astrophysicist Randy or something along those lines...

Maybe you just don't know how to grind a sharp bit.
You been looking in our windows?
That I do, but do you know the rule of thumb per bore size ratio to the size of boring bar? Even at 3/4" mine is too small.
So I will start calling you Pee Wee.
You're doing it like a boss, good work. It's nice to see Stihl sourcing those cylinders out from Gilardoni. They've been making nice cylinders since the days of the Pioneer P-60 and Husqvarna 1100CD.
I've not had any chatter at all?
That's good then. I just couldn't get rid of it with a small bar. Your surface finish will be better with a bigger bar though.
That bar you made is sweet. I would like to have something more solid......hint....hint. :msp_sneaky:
I did these five the other day, the plating in the XT jugs is a #####.....
The big bar and bigger bit go through plating like a seasoned champ!!
That plating is why I went back to the "wimpy" bar. The carbide didn't like that stuff at all.
Your lathe isn't powerful enough to utilize carbide. I pretty much never use carbide, my lathe isn't powerful enough either, HSS works way better with our small lathes. Not hard to make a big boring bar, do you have a HD holder? That will take a 3/4" bar?
No I just have that little tool post. I figure when I get a mill it would be a cool project to make a post just for boring and a more rigid bar.
Ya there is some good DIY holders out there that I've seen. I've got the quick change tool post, and it came with a HD holder, works great.
There are some QC posts for the small lathe.......I may look into those too.
Damn MTAD.
How do you cut out to the edge of the bore? Do you have a carriage stop? I'd like one of those micrometer carriage stops. So far I just use the old eyeball then "0" out the indicator then go to 0 each pass.
Nice work Randy any one would think you were a machinest,what size can ya fit in your tool post ?.
