That seems too aggressive of a cut for hss compared to how I've done it at my last shop.
Usually .005-.008. And I never reamed anything bigger then 5/16.
We'd bore it out right on the money smooth as a babies ***. 32 micro finish or better. Usually 6-12micro.

Yes I would agree but due to my setup I cant use a boring bar to get it close since the end is only supported by the steady rest. I think their would be too much tool pressure and either the part would push away from the tool or vice versa. I suppose I could have tried a couple more steps but their is no way I would have been able to do it cost effectively for 1 part. If I was going to do thousands of them I would get custom soft jaws and a thru tool coolant boring bar, make a couple passes to get within .005 then use a thru coolant reamer similar to the ones ph horn sells. but for 1 part just get some cheep tools and burn em' up.

At the end of the day though I was quite happy with the finish I dont think I was 6-12Ra but if I had to guess I bet I was at 15-20Ra.

Update. Except for the apron, if you don't see it, it is soaking. Soaking the apron tonight after I get some room in a bucket.

Thanks Ty.

It's not going crazy fast, but it's not stalling either. An hour or two (or three) a day is keeping things rolling. You see the shine to the left of the carriage on the front way? Yeah, notice how it doesn't shine on the left or right side? That's because I haven't gotten there yet.

The 4 chucks and 1 rod were a little bit of a chore to get out of the turret, but after soaking for a day I did the first cleaning last night. One chuck is still stuck (it's a keyless one so it's a little hard to grab something without mangling it) but they are all cleaning up nicely. Second wash and then a rinse is tonight for those.

If you've ever done KP in Scouts, that's how I'm having to clean stuff. First is the heavy scrub, second is the soapy water to take the last film off, third is a quick dunk into the rinse water and then off to dry.

Kitchen gloves are a better choice compared to the disposable shop gloves I started with.

Got the turret split in half (top and bottom) last night. There's really not a lot going on inside of that thing. What was inside of it, and I have no idea how it all got there, was a boatload of brass chips. The fluids they used served as a nice binding agent, so everything was stuf to everything else. It's not soaking right now, the apron is, but I have a big container that I could use to get things started on the turret tonight.

I was concerned that the turret would be really complicated and I'd have a lot to break down, clean up, and put back together. That's not the case, so I'm pretty happy that it doesn't seen like an overly busy portion.

Also painted the spindle cover last night. Well, the outside of it. Will flip it and do the inside today.

After that, will start taking apart the apron and maybe do it's first cleaning. I might be taking pictures for this one since the manual doesn't have an exploded view of how everything goes.

EDIT: Oh yeah, the selector for the high/neutral/lock/low has been soaking for a few days now too. Looking forward to digging into that, hopefully tonight. It was really messy, but after the fist day of soaking I did a quick brushing and even that made a pretty big difference.
