Boo boo's aside, it's a very fine piece of machining, with good surface finish and what looks like good accuracy. Very nice indeed.

I continue to follow this thread with a lot of interest. I enjoy seeing your set up pictures as well - it's always good to see how people set up - gives a lot of good ideas.

That looks like a perfectly functional cylinder to me, Zee!

I don't think you would even need to use any goop for that groove.  The threaded holes don't go anywhere, so you won't leak any air.  If you want to fill it, then by all means do so. But it'll be covered up by the end cap.

But do what makes you happy!

I’d either blame the groove on the drawings or write it off to “artist discretion” . TBH, everything is looking great. I’ll show you mine when I figure out how big of a problem it’s going to cause. I have bared all, but only to a select thirty or so: still get very sweet Christmas cards from twenty something of them  every year :mischief: :naughty: :lolb:. Of course, Lou understands why :Jester: :lolb:

Sure. I believe everything you say.  ;D

A little bit of progress.
Worked on the valve, valve cross bar, and valve rod.

1st pic shows milling of the valve. A pocket had already been milled.
2nd pic shows the valve being taken off the parent stock. (And yes...I made sure the saw was right side up.)
3rd pic shows the finished parts.

Oh...you notice those light bands around the valve rod? Want to know how that happens?
I'll tell you anyway. That happens when you start turning down the diameter after forgetting to tighten the chuck.   :facepalm:

The valve cross bar and valve rod are stainless steel.

P.S. In the 1st pic, three parallels are on the left side of the vise to balance the load. In the 2nd pic, a piece of aluminum was used.

What bands?? The parts all look good to me Zee. Nicely done.

Thanks Bill.

What bands??

Pretty hard to see I guess. I could change the image to show them up more but they're very light. They'll be gone once I polish and assemble.

Also get those bands when threading the rod and not taking the diameter down not quite enough....

Your surface finishes look good. I have purchased machined parts from vendors that don't look as good as those. I think you're beating yourself up on the bands - if they will polish out that easily then no harm no fould - although I do understand your frustration from how it was caused. A good haul of machined parts though. Definite thumbs up.

Thanks Stuart. I'm not beating myself about the bands....that was about letting newbies (LIKE ME) know. However, you're spot on about the frustration. It smarts to forget to do what I think should be basic operations. I had posted on another thread about being off by 10 thou. I couldn't understand why...I was using the DRO. Now I realize it was because I hadn't locked down an axis and the backlash got me. Milling pushed the part aside.

Still...so far I feel like I'm improving and that's what counts.

Just today...I milled a part that was supposed to be (exactly) 0.375. And I nailed it. There was a small happy dance in celebration.  ;D

Thanks guys. That helps keep me up.

Now for what brought me down    :cussing:

My tendency to over-tighten, over-pound, over-eat got the best of me again.
(I over-drink as well but not in the shop.)

I was trying to tighten down the compound onto the cross slide when I encountered an infinitely turning nut.
I had stripped the bolt.

As best as I can tell, it's a 20 threads per inch. I suspect a 5/16.
Off to home depot to see if I can find something close enough (taking good nut and bolt with me to compare).

I suppose I could make but I've never done threading before (and if a die exists, I don't have it).
 :slap: Make? Without a compound?
