Mark, One of the things that I've learned by watching Joe Pi's channel is to turn the tailstock end of the part being machined first so that the stock, larger OD can support it with less deflection. I.e., turn the taper section first, then the section to between the taper & the threaded section, then the threaded section, followed by the knurled section. If you need to manufacture another similar part in the future, you might want to try that to minimize problems caused by excessive deflection. Regardless of what technique you used on this part, I'm sure that it will work just fine. I often learn from your videos too! Keep up the good work!
If you would have turned it down starting from small size to bigger size it would be more ridge as you went back to bigger size. If that makes any since to you. Just thinking
Nice work as always, but I do wonder about your order of operations. Wouldn't it have made sense to do the point first, then the .125 section, then the threading to avoid the deflection when working on the end of that thin needle?
Winky: a 'Memory Lane video' ... tnx It has been 50+yrs since I worked on B&S engines in dad's little shop. Do you have access to the carb? I "think" I recall the carb having a removable "seat" that mates with the needle-cone. Your Orig tip has a rough surface... and you may have poor mating with your newly-formed cone. Look for an threaded set-screw like part with a thru hole tapered to mate. It likely would have a Slot cut for a screw driver removal. You may need to make a screw driver bit to fit... with straight shank. [most small screw drivers will have a flare width that will interfere, as the slit can only be cut outside the thru hole] the "special tools" drawer had 2~3 close fit straight shank screwdrivers ONLY for use on those seats!! -- under penalty of a serious scolding !! ~ 'Rusty', a retired mainframe systems analyst, with some long un-used "shop skills" experience.
I don't have the carb but I made one before I made the video and it worked well. I think at most the slight variation will make it more sensitive to adjust. If I remember right most the carbs has a 1.5 turn from bottom intial setting. This means there is a sizable gap when set correctly so getting a perfect mating surface is not absolutely necessary. Thanks for the comment.
Mark, Nice job as usual. Seeing as much precise work as you do, an optical comparator might be of help at times in confirming precise sizes and angles. Beats our old fashioned way of measuring and doing the geometry and consulting trig tables. Don
Cool that's the reason I'm getting into machining do some small jobs that otherwise couldn't get. Or it would cost good bit to get a real machinist to do it.

Hi Winky I couldn't finish watching your video. That lathe of yours sounds like a Catalina flying boat trying to take off. Any chance you could move your microphone out of the gearbox?
You should hear it on my end! New gears are needed but hard to fins and expensive. I was thinking about converting to a chain drive but the reverse is a problem. But also agree with the comment below. Its an old south bend and it will never be quiet... never was, especially at full speed.
The lathe sound are fine, it was the steam hammer noise in the last few seconds of the video which had me reach for the sound kill button! Someone may claim it was music? Nope...
I probably wasn't too clear. I would expect an old south bend to make the sounds that it does. I suspect you were using the microphone on your camera, and the camera was closer to the gearbox than the operator. You end up with the mechanical noises drowning out the commentary.
Pretty neat little project.
I think so too! Thanks
Well done. Thanks for the video keep on keeping on.
Thanks for watching!
Nice video thanks for sharing it. Antique vehicles always need custom made parts.
I've made a bunch for the PlayTrac tractors
We made Brass needle valves in our repitition shop, the thing you should have done first is machine that taper, other than that it came out well 👍
Dang, you're right! Ha Thanks

It may be a simple job, but well executed as always Mark.
Thanks 👍
Hello Winky, nice video, thanks for sharing with us, it's a joy watching you make parts, and your commentating is excellent, cheers from me. 😷👍👍👍👍👍
Thank you so much!
Buen trabajo Sr.Winky, el inserto para tornear aluminio es el mejor para el latón, bronce y hierro fundido. Pruébelo,
hay un antes y un después.
I've heard that. I need to get some. Thanks!
Nice job! Les in UK 🇬🇧
Thanks
Very nice machining, nicely done.🫵🏼💯🆒

This is very true... love Joe's stuff. Also, I think overall it would have been more difficult to do it like this but potentially more accurate.
If you would have turned it down starting from small size to bigger size it would be more ridge as you went back to bigger size. If that makes any since to you. Just thinking
Yeah that is true. It worked okay but I should have machined the tip first
Nice work as always, but I do wonder about your order of operations. Wouldn't it have made sense to do the point first, then the .125 section, then the threading to avoid the deflection when working on the end of that thin needle?
I agree wholeheartedly.
Good point! I agree
An angle ground on the cutting face of the parting tool would eliminate the need for removing the scrap on your finished part
Yeah, I need to do that more but for 1 or 2 parts I didn't want to regrind the tool. For deeper cut off work the angled tip makes the blade deflect.
Absolutely brilliant video
Glad you enjoyed it, thank!
I think I would have polished the tip.
Good idea, I did take some steel wool to it after I made the video

Trig? For me a protractor is about it.
@@WinkysWorkshop me too!
Turned out nice mark 👍👍
Thanks 👍
Great job as always! 👍
Thank you!
Nice work Mark, you make it look so simple, well done!
I didn't say but this was my second attempt :o)
@@WinkysWorkshop LoL 🤣😆
I wonder if you could have chucked the original up and resurfaced that pointy bit to make it work OK?
The original worked well. I was making them for a couple of collectors that had old carburetors that were missing the needle valves.
I make my own as well Mark .. Some are hard to find ! 👍👍
The hardest part was figuring out what the threads were.
Nice job well done!
Thank you! Cheers!
I got nervous when you were using the die grinder. I don’t know how many times things like that have jumped and taken a layer of skin off my hand
In this case I felt comfortable but I have had them get away from me. It's amazing how fast they can run around inside the end of a pipe!

Hi Winky

Turn the sound down, that clunky noise is part of the charm of the old South Bends!

What was wrong with the one you copied? 🤔
It was okay, this was for a collector of vintage motors and David Bradley PlayTrac. He had a few missing.
@@WinkysWorkshop figured as much. Thank you for the reply!
