great vid Mr P!

[@mrpete222]

Thanks Tony

[@criticallook1352]

I didn't know today was Arbor Day?!
I was surprised Tony didn't say this!

[@saartal4524]

No worries... I (we, I dare say!) will be sure to watch all your future videos. We love watching them. I personally saw most of your videos... enjoyed every minute!

[@dannyl2598]

Thank you Mr Pete.
You gave me a much better understanding of some of the things that I have accumulated in tools and how they can be used together. The double dog is a great idea.
Can't wait to see the next video.

[@mrpete222]

Thanks

[@TheArsonsmith4242]

Thank you for another great class. Never worry about going into to much detail. Better to have some review than miss something important.

[@mrpete222]

Thank you very much, I'm glad you like the way I make my videos

[@MyHeap]

Great explanation for us neophytes Mr. Pete. Thanks for taking the time. Double Dogged ... Now that is daring!
Joe

[@mrpete222]

lol

[@ChrisHarmon1]

When he said double dog I started thinking “Yeah! , I double dog dare ya!” lol.

[@champtree]

Just this week, I found a bunch of new mandrels in my late Dad's lathe and I wondered what are these for? What a blessing your videos are!!

[@mrpete222]

Thanks, I'm glad you know what they are now

[@johnapel2856]

I didn't know much about mandrels, and now I do!
Thanks.

[@mrpete222]

Thanks

[@johnc4352]

This is the kind of video that made Tubalcain famous! Thanks Mr. Pete.

[@mrpete222]

lol

[@billherreid9661]

Thanks so much! I especially liked the comparison to wrench lengths. That's a good thing to think about in any work holding.

[@mrpete222]

Glad you liked it

[@Daledavispratt]

Looking forward to parts 2 and 3. Thanks, Mr. Pete! :-)

[@mrpete222]

Thanks

[@AWDJRforYouTube]

Very exceptional info on lathe mandrels. I used my first one as a machinist trainee at R&R Machine & Tool, a small 5 man job shop...Owner's had country music on the radio all day...loved Barbra MANDRELL...I digress lol.

[@mrpete222]

lol

[@dragman377]

Thanks for the info Mr. Pete. More things I now know about. I continue to learn watching your video's.

[@mrpete222]

Thank you very much

[@stormtaker63]

I bought a lot of 20 on a online auction and I am so glad I did. Perfect for making gears and pulleys. Fantastic video!

[@mrpete222]

Yes thanks

[@RRINTHESHOP]

Those are a must have staple in the shop. Great info.

[@mrpete222]

Yes

[@napalmv8356]

Mr. Pete thank you for another great video!

[@mrpete222]

Thanks

[@glennjohnson9545]

Love your videos. Can’t get enough of them

[@mrpete222]

Thanks

[@bulldozer7656]

Thanks for the lesson Mr. Pete!

[@mrpete222]

Thanks

[@Tryin2FlyII]

Great stuff mrpete looking forward to the other two videos, and you can NEVER give me or "us" ( meaning your students ) to much information. As always "Two Thumbs Up"!!! Sir Thank you

[@mrpete222]

Thanks

[@pjhalchemy]

I've made some but never used the "new" ones but for those prices and postage a Plus for sure. Re-crowned my HF 6" belt grinder and the 1x30 also using custom ones...much smoother and Quieter now. Looking forward to the casting and turning in the series. Thanks so much for sharing with us, Mr. Pete!

[@mrpete222]

Thank you. Give me another week or two to finish the videos

[@niemdan]

A great teacher. Thank you for passing your knowledge

[@mrpete222]

Thanks

[@christurley391]

When you need them they are priceless. Thanks for the video.

[@mrpete222]

Yes thanks

[@russelallen5342]

Great! Loved the tiny Crescent wrench! Thanks

[@mrpete222]

lol

[@brandonnugent1887]

where did that microscopic wrench come from?!

[@cliffordfender1159]

Lyle, I thought I might be a little bored with this title but, the longer I watched, the more it attracted my attention !!! Loved it, Kind of reminded me of my school days. Thanks pal, for another great one. Your friend, Cliff

[@mrpete222]

Thanks

[@gwheyduke]

Good lesson. I learned what I needed to know.

[@brukernavnfettsjit]

Very very nice. This is perfect for me. I have a project coming up where I need to crown 4 wheels. Looking forward to seeing how its done.

[@mrpete222]

Great, watch for

[@Aubreykun]

Thank you for continuing to share your knowledge with us.

[@mrpete222]

Thanks

[@bobvines00]

Lyle,
Watching this video reminded me of the Machine Shop class I took in college (as an elective). If I remember correctly, we machined our own mandrels (just lathework, no grinding) and gear blanks (leaded steel), pressed the gear blanks onto the mandrel and finished turning it to the appropriate size. Then we put the mandrel onto the horizontal mill with an indexing head with tailstork, & installed the correct gear cutter onto the mill's arbor, and sweated the whole time the indexing head was being used in fear of messing up the indexing. I lucked out and got it right. :)
I really wish that I had had the opportunity to take Machine Shop classes while in High School! I'm certain that _your_ classes were great.
Unfortunately, the WWII Machine Shop training building at college was torn down within the last 5 years to help make room for a large lab? building on campus. But I bet that they do not still have Machine Shop classes. I understand that they _do_ have a Machine Shop for students to build projects and, as a team, things like mini-Baha racers, that often must be amphibious.

[@mrpete222]

That is interesting, thank you for watching

[@darrengreenwood8846]

This guy is great keep those videos coming I've only just found your channel an I'm getting through your videos brilliant an sometimes funny like the bubber reference good job sir

[@mrpete222]

Thank you, I am glad you found me. Keep watching

[@jeffhulett4194]

Nice video, can't wait to see the remaining series.

[@mrpete222]

Thanks

[@kb0zyh]

Very interesting. Thanks for another great video.

[@mrpete222]

Thanks

[@tomkizis7014]

this is the video I have been waiting for.

[@mrpete222]

I'm glad you liked it

[@reg.treg.t]

Another great lesson love the shifter

[@mrpete222]

Thanks

[@apollorobb]

My next project is to make mandrels . Perfect timing !!. Excellent video Lyle

[@mrpete222]

Thanks

[@rolandsmith2141]

I got to the page in my "know your lathe" manual about mandrels but didnt fully understand there function. Found this ...........just fabulous, iIts a strange world !, I moan at the kids for being on the net/CZcams etc but without it how else would a 55 year old student (hobbyist) of engineering get all this valuable knowledge and for nothing. Thanks

[@mrpete222]

Thanks. So true.

[@JamesDedmon]

The last time I remember using one of these mandrels was in the first shop I worked in. We had one that was marked with a grind mark that was used for a bore gage when honing out bevel gears. The the parts were OD ground on a bearing fit using another mandrel.

[@mrpete222]

That would make a good gauge, because of the taper is so slight

[@kevCarrico]

very cool video, mr. pete - thank you!!!

[@mrpete222]

Thanks

[@curtiswhite1107]

Thanks for the video! A few weeks ago I bought a box of reamers at an estate sale and there was a 5/16" mandrel in the box. I had no idea what it was.

[@nicholasstanziola]

I'm not far from Millersburg, PA. I had no idea that ANYTHING was ever made there, let alone machine tooling. Thank you for another great video.

[@mrpete222]

That's quite a coincidence. Thanks for watching

[@jeff-lindawells7760]

Great class sir loved it!

[@mrpete222]

Thanks

[@MrShobar]

Your viewing audience is definitely looking forward to more aluminum casting. I thought you were going to pan the expanding mandrels. They are the only type I've ever used, and they work quite nicely. They are expensive, though, as you mentioned.

[@mrpete222]

Yes thanks

[@georgeantonaros5580]

Fantastic instructional video !! 🤗

[@mrpete222]

😄

[@rleeAZ]

Never too much detail professor Pete :)

[@mrpete222]

Thank you very much

[@MrKidkiller159]

I take the assembly and lightly drop it on giant chunk of aluminum to tighten the work on it . fabulous tooling love them for the motorcycle repair and modification i come across so offten.

[@mrpete222]

Good idea

[@MrKidkiller159]

I use mandrels and expanding mandrels of many sizes in my shop , thanks @mrpete222

[@mrpete222]

They sure are handy

[@nevetslleksah]

Never seen an adjustable wrench that small LOL. Thanks for the tip on “double dogging”.

[@mrpete222]

Thanks

[@stanwooddave9758]

Thanks for sharing. Now onto spending some money for some popular mandrels size(s.) I can't wait for the other video's.

[@mrpete222]

Thanks

[@scottmichaelharris]

You re awesome mr P

[@mrpete222]

Thanks

[@tomm.1348]

Excellent video, thank you very much.

[@GarryFullerSr]

Very Nice. Great Demo.

[@mrpete222]

Thanks

[@ErnieNoa3]

Very good explanation!

[@mrpete222]

Thanks

[@BurtonsAttic]

Informative!

[@mrpete222]

Thanks

[@glenking3337]

I would like to see the plans for those 10" disk sanders that you made in your highschool.

[@johnstrange6799]

Excellent. Thank you.

[@mrpete222]

Thanks

[@theworkshopmechanicchannel3296]

Thanks for sharing.
Ps
I like that tiny wrench 🔧

[@mrpete222]

Thanks

[@tced2858]

I live just up the road from Millersburg PA, Mr Pete

[@mrpete222]

Thank you, I never heard of that company except on these mandrels

[@aceroadholder2185]

Note that old arbor presses often had a V-groove in the base casting.. this was so that the press could be bolted to the end of the lathe bed to speed up production when running work on mandrels between centers.

[@mrpete222]

Thank you, I did not know that

[@elsdp-4560]

THANK YOU...for sharing.

[@mrpete222]

Thanks

[@stephen122]

I also worked in the factory that made the London buses, I was on a production cylindrical grinder and while one part was being ground on auto we would knock the last part off the mandrel by hitting it on a cast iron post about 6" diameter and 4ft tall. The mandrels had safe centres.

[@mrpete222]

Thank you, that is interesting

[@nowayjerk8064]

landis grinders !!!! grand dad worked in the chase division . i just bought a zippo with landis on it yesterday at auction .

[@mrpete222]

Wow, what a coincidence

[@MaturePatriot]

Gotta come to some Illinois tool sales, to find more inexpensive expanding mandrels. LOL Great video. See you next time.

[@mrpete222]

I have never seen any expanding one's at auctions

[@custidorumbo1017]

very good

[@kevinwillis9126]

Thanks for sharing sir..

[@mrpete222]

Thanks

[@warenmann1042]

After watching this video, about five different points of confusion and how different pieces of equipment were designed and used suddenly became clear. it was an amazingly satisfying moment. Also, I wonder if the term we used to use as a kid, ( I double dog dare you ) has any origin or connection to the use of lathe dogs. Thank You...

[@mrpete222]

So happy you enjoyed it

[@stevecanny1583]

I always wondered where the expression "I double-dog dare you!" came from, I guess it arose in metal shop! Just kidding Mr. Pete, but that gave me a chuckle as I was watching. Very clever approach, to take up the workpiece torque with the dog itself, taking the mandrel friction out of the equation. Great video, I just happen to be trying out some mandrels for between-centers lathe work at the moment, so this one is very timely :)

[@mrpete222]

Thank you, I'm glad you liked it

[@user-wo7rz3yn4o]

Ok I can hardly believe that is REALLY Mr. Pete's complete mandrel selection!!! I'd bet he has drawers full of them! LOL

[@mrpete222]

I am ashamed to admit, that's all I have

[@ondrejjanovec6700]

Good video.

[@mrpete222]

Thanks

[@mikeadrover5173]

Very interesting and well explained thanks ~!M~

[@mrpete222]

Thank you

[@OleGramps53]

Are we going to see a series on making grinder belt wheels for your belt grinder? Which would be interesting to see the different crown shapes you can make for it to use in various applications.

[@billcodey1430]

Mr Pete with the tiny wrench in the workshop.

[@mrpete222]

lol

[@freddydoe6347]

Give Abom his wrench back.

[@sodster68]

Double dogging eh, you ol dawg! Thanks again for a pleasant lesson, means a lot!

[@mrpete222]

Thanks

[@FKreider]

Are you going to build the whole belt sander? Would love to follow along on that build!

[@mrpete222]

No, just the wheels. The patterns were destroyed 25 years ago

[@gecko8808]

Mr.Pete: in your opinion, what is the most precise set up: holding workin 4-jaw and tail stock center or holding between centers and driving with lathe dog?

[@mrpete222]

That is a hard call. Probably the four jaw

[@benpress8884]

I noticed in the listing the title is Lathe Mandrels, aka Arbors. They are not the same. Mandrels hold the piece to be worked on. Arbors hold the tool that does the work.

[@kurtfattig9370]

This is great. I'm wondering if someone dared you to double-dog that mandrel?

[@mrpete222]

lol

[@turnersparadise8368]

That little adjustable wrench at 13:00, I bet that was metric, wasn't it?

[@flashcraft]

Hi mrpete222, thanks for the instruction. Did you know you sound like Jimmy Stewart?

[@mrpete222]

Yes thanks

[@life.is.to.short1414]

Was wondering what those was at work.. i.thought it was to use to alignment the lathe lol

[@1889michaelcraig]

Hunny Mr pete said buy a selection of Mandrels/Tools so its ok.

[@mrpete222]

Yes

[@BedsitBob]

A different approach for the oversized bore, is to machine a piece of stock to have a shoulder on it, thread the machined end to leave a non-threaded length slightly shorter than the thickness of the blank.
Without removing the mandrel from the chuck, place the blank on it, put a nut on and tighten it down, to hold the blank hard against the shoulder.

[@mrpete222]

Thank you, that is an excellent alternative way of doing it

[@BedsitBob]

Thanks.
Provided you don't remove it from the chuck before use, it is 100% accurate, even correcting for chuck run-out.

[@4speed3pedals]

Thanks for another informative video. Shars also sells expanding mandrels. I own one and I am very satisfied with the accuracy. I am not a tool and die maker, just a 6" Atlas/Craftsman lathe. For under one inch, appproximate savings is about $15.00 vs KBC. I went to the KBC site and they do not say where the tooling is made so , I assume it is also China. Anyone know for sure?

[@mrpete222]

Thank you, I will look them up in the shars walk

[@mrpete222]

I meant book, not walk

[@clintmullins8670]

What if one is in need of a longer mandrel, say rather than 6", perhaps your work is up to 10-12"?.. (working on thin wall tubing
Thanks!
Sincerely, Clint

[@clintmullins8670]

and thank you for these videos!

[@buildtherapy8842]

I should be studying for my exam tomorrow but here I am for the last two hours watching and I don't even own a lathe

[@mrpete222]

Do your studying first, then watch my videos

[@greybeard3759]

I don't know where you want "answers" posted but those pliers with the hammer head is for installing and removing wheel weights.

[@roeng1368]

Good video as always. You speak a lot about school shops and teaching in them, but are there still school workshops in the US of A ? Or have they been replaced with media studies or gender studies or some other nonsense ?

[@mrpete222]

There still are some shops, but most have been turned into computer labs where the kids play games

[@Aubreykun]

A lot have been removed, some still exist. Wood shop is the most common of the traditional shop classes remaining to my understanding. Schools in some areas have added higher-tech teaching like web design, CAD (for using 3d printers) and extracurricular robotics teams.
They're not the same sort of activity however.

[@multiHappyHacker]

Back in '08 or so we had a shop with probably a drill press, an oxy-acetylene torch, a stick welder, a bench grinder, angle grinders. Whether there is a qualitative reason for not giving the kids expensive machine tools to tear up, well one can only guess. Maybe they have some in urban schools with more money, but I doubt it.

[@GarryFullerSr]

Only a few kids today would be interested in this type of classes or work. Most are Snowflakes that want most things given to them. If they work they expect to start at the top.

[@multiHappyHacker]

It's a silly notion to think that can't be changed.

[@jeffanderson1653]

I just tried to turn a spacer with a .625” bore. I need a mandrel. It was not a success

[@dimitrioslykissas7981]

Is this the real purpose of the cut-outs on the arbor press "platters"?

[@mrpete222]

I do not know

[@chrismiller9740]

Does mandrel need to be secured w dog or can they be chucked?

[@askquestionstrythings]

That is a good question

[@richardgregory6653]

A mandrel a day will keep the chips a flying! thanks Prof. Peterson

[@mrpete222]

lol

[@mrayco]

I think I have new project to work on👍👍

[@mrpete222]

lol

[@PaulSteMarie]

Nice forged lathe 🐕

[@mrpete222]

Yes

[@davecc0000]

Link to that micrometer on Banggood? Also a link to your video introducing the mic?

[@mrpete222]

goo.gl/ScdvR6

[@davecc0000]

Thanks for the link. Unfortunately the mic they're selling now doesn't have that nice HUGE digital display. Oh well...
Anyone know of a similar one that large digits like the one MrPete is showing here?

[@michaelschnock3998]

With all respect, that expanding mandrels are not "expensive" . I pay 15$ + shipment . each , or 40$ for 2 of them + shipment . look at arc euro trade . everything i ordered and received was within dimension and expectations . of course they are no Starret, mitutoyo, etc etc but within 1/100 mm! and that seems fine for me. all the best to you , and thanks for sharing

[@mrpete222]

Thank you, that sounds like a good source

[@bestfriendhank1424]

Are the mandrels hardened and then ground or ground then hardened?

[@mrpete222]

The former

[@rlsimpso]

I don't think there could be too much detail @7:00 explaining something like this. These are simple devices, but understanding how the are designed and made is important to using them correctly.

[@mrpete222]

Thank you

[@Ed_Stoddard]

Your views on this one might be lowered by the 3 minute wood-mizer ad that I had to watch to get to your vid. I did hang in there though.

[@mrpete222]

I have no control over the ads on my channel

[@luderickwong]

Sir, i though you will make a initial “grove“ on the 3d printed mode when i first see this clip, in that way it will save some time on the lathe work, right? but you don`t. I then guess there is a reason behind. Is it the “grove“ will. Make the casting easy to crack or difficult to mode that way?

[@mrpete222]

Never thought of doing it that way

[@Aubreykun]

2 Reasons:
1. The 3d print needs support else it will collapse on itself, the hot plastic will simply fold over.
2. Withdrawing the pattern without damaging the mold requires a slight taper of a specific slope (called pattern draft) on the outside edge of the pattern. He's covered the whole casting process in many of his other video series (and makes me wish I had the space to do it myself.)

[@Aubreykun]

Additionally the wheel he is making is a crowned one for a belt sander, not one with a V- (or other) groove for a normal belt

[@luderickwong]

I have to apologise for my question is not clear, or even misunderstanding. Let me rephrase it, what suprise me is the axis of cutting, i though the 3d model will be cut on the other axis, just like we cut an apple or orange in half the normal way, from sterm to butt, north pole to south pole that kind of half. And i fail to mention this point in my question, it make my question look stupid.

[@Aubreykun]

+luderick wong
Now that you've explained it better I want to know that too haha

[@dafodilist]

I shall fit that info in somewhere!! Thanks.

[@mrpete222]

Thanks

[@stephen122]

I remember when an american gentleman from the Gillette company came to Gillette UK Ltd and he said it is liable to gaul we all looked mystified until we realised gauling is what we call Pickup :)

[@mrpete222]

It is funny how we have different terminology

[@daveanderson2316]

Barbara Mandrel? ;)
