MACHINE SHOP TIPS #51 Lathe Project Plumb Bob Pt 3 of 3 tubalcain

[RedStarRacing]

Like your style - Thanks for all the excellent videos

[madaboutpix]

i'm going to repeat your project, thanks for the inspiration and guidance.

[ahz123]

Very nice indeed!



[weslake898]

I did this as part of my B-TEC first in engineering at college, 1994! we also made a Tap Holder.

[one6all]

I'm very proud of you and I learn a lot thanks

[08jobart]

Really enjoy your videos. some time you should do a video on different ways to harden steel. i use a lot of stress proof shaft in my shop but i have never been instructed on how to properly harden it, if there is a good way to do it. i am a rookie machinist and i have learned a lot from your videos. thanks

I know you said no questions, but it appears your drills (except the last one) lift when they make contact and start cutting. Is this normal, a problem, or an optical illusion?

[mrpete222]

@BerkeleyGang Its pretty common. Bit may not be straight, chuck innaccurate etc. Thats why we center drill--the bit is forced into drilling accurate.

[BerkeleyGang]

@mrpete222 Yeah, but at 7:12, the center drill jumps upward, introducing an inaccuracy that's now going to be repeated by the remaining drilling operations.

I know for this project, especially being purely for demonstration, it's a minor point, but I'm trying to understand things. One of the reasons I bought a mini-mill was because I wasn't able to drill accurately (enough) with a drill press. I'm very sensitive about accurate hole placement when drilling.

Thanks.

[Mcgheekevin1981]

@BerkeleyGang You may also find if you are having this problem your tailstock is out of alignment which can cause that to happen. If you align your tailstock and still have that problem, your lathe bed is probably twisted. All metalworking lathes must be shimed to the floor they sit on until the tailstock is in perfect alignment with the chuck. I have 4 lathes in my high school shop I teach in and all were installed without shims, I am in the slow process or doing that work myself.

[BigAgitator]

@Mcgheekevin1981 I agree but I have a question. If his tailstock is out of alignment, wouldn't the center drill want to wander as well?

[Mcgheekevin1981]

@BigAgitator my center drills do not move, they are too rigid and strong to bend, but drill bits are a different matter. Hard to say what the exact reason is in his videos but when you set up your lathe and make sure your tail stock is aligned, if this happens it is usually from that reason in my experience.

[BigAgitator]

@Mcgheekevin1981 Makes sense. Thanks for explaining.

[BigAgitator]

@BerkeleyGang I've noticed that with my lathe work too. It does seem common. My quill is well centered to the spindle.

Great to see you posting video's again. Next time you're over at your friends place, take a photo of his plumb bob collection and add it to the end of this video!

[etothejtheta]

Love the project walkthroughs.

[taiden]

awesome video, I love learning about machining from you. I don't have access to a full machine shop, but once I graduate I plan to pick up some hobby stuff. Thanks again!

[MGARestoration]

Great to see another video from you. I have watched every single one of your videos and have really educated myself on machining. I have a 100+ year old Seneca Falls lathe that I use regularly and practice your techniques. Many Thanks!

[MrDan27611]

Glad to see you back in the shop! I'm also glad to see I'm not the only one who takes the summer off from metal work. Winter is coming though, time to make some chips. Great video as always. Thank you!

[ohm1163058]

So I have about a 6 foot long piece of hex stock kicking around the garage, I think I know what my next little project is going to be, well after I make a spacer bushing for my alternator, its either this or a zip gun :)

[firemanemt198]

Thanks so much for these awesome videos Mr. Pete, please keep up the great work

[flunkywill2000]

thanks, i always learn something no matter how simple the job. would have liked to see the tap handle in the tail-stock.

[timothysvec]

Thank you Mr. Pete for another great video!



[FireDropTechnologies]

Ps,

I don't know if the link will stay up or for long or not,

Last time it didn't.

[FireDropTechnologies]

Say pete?

I wrote you about some

progess on that turbine pattern,

Take a look when you have a chance.

[Geebuv]

Great series Pete. I enjoy watching the project videos, keep them coming!

[steveBB30]

thanks for showing a great simple project again. And thanks for showing that there are often several different ways of achieving the required functionality/task. [the facing and the designs for ensuring the bolt lies flat]

[ROCKNTV1]

@mrpete222 thnx mr pete 

[aryesegal1988]

There's nothing better than seeing another machine shop video uploaded by you, Sir! :] Always a pleasure to learn something new. Thanks for taking the time to do all these educational videos!

[priority2]

I always learn something new no matter which one of your videos I watch...please keep them coming:)

[smackbabie]

Good stuff as always. Thanks for sharing.

[AeroSport103]

Thanks for producing the new videos. As always very informative.

Standing by for the next machine shop video!

[MabrayFarm]

Nice series, always enjoy your videos. Thanks for making them.

[BNSFfan1996]

im in Highschool metal shop and so far ie made a punch, the operations are ery simaler to these.

[Nator187]

How about a segment in cutting tapers with the other 2 methods?.. Awesome videos though!  :-)

[2007markb]

That small drill cut through like it was hot butter

[killakobra]

perfect timing. just finished part 2 when part 3 popped up.
