Showing the finished part at the beginning is a great idea. It helps us understand where we are going as you make the part. Please keep doing that.

Sometimes it's the details along the way: I made up a set of copper-pipe jaw shields for my (small) 4-jaw a while back and was having trouble with them springing out of place and generally not conforming well to the jaws. After seeing this I hit them with the propane and son-of-a-gun, a little light hammer-forming brought them into close-fitting, custom shape! That annealed copper is like a whole different material. Thanks Tom! :)

Must be a cool feeling to know you can create just about anything you want. 👍

A big, heavy, horking tool to do a delicate task, yet stay true. Love the tool makers task. Thank you Tom.

Making the purely precision pleasing to touch, and to the eye is an added benefit to the senses, and may engender more than pragmatic use to more frequent use, like that favorite bit of clothing we all favor over others in our wardrobe. A precision piece of art!!

Clever shot of the drill breaking through the backside of that chunk of steel. I've never seen that view before. Very cool.

Nice close up photography! Man that Drill was moving!!

WOW... first time on your channel. This is awesome. I can learn so much from you. I’m new to machining, only about six months and I’m hooked at 59 years young. Tom K at Hilltop Machine said I should see your channel. Your newest sub. 👍Thanks for what you are sharing. Ron...

Oh, how I've missed your lathe and mill work. I hung onto every minute of it.

Nice touch on the radius to avoid chatter, well done. Thanks for the video.

SUPER cool. What a great tool and loved the radius cutting. Thank you!!

When you were using the boring bar to face the shoulder feeding in towards the center. That's a LOT safer than feeding out then cutting the shoulder after. I just learned a trick, thank you

Gone through all the vids so far. Much improved! At this point a real step above anything else on here.

I've got an excellent performing flycutter that uses the round tips. Learned something in this one that will help while using it when I want an inside radius between a vertical and horizontal surface and getting it without chatter. Thanks very much.

👍really like the grip design. reeks of craftsmanship as always with you.

Great video. Thanks Tom.

Wow!!! Once again Tom, you got me, in all my years I never saw/did that one!

Love these videos , not seen the trick with copper tube before

Never one to miss an opportunity to be a putz I complained about not enough machining content and that I'd have to unsubscribe, waah, waah, waah and then...this. Such is life.

I have a lot of drops that are around that size of 8620/ 9310//4140/ 4340/1045 great material for your project squareness...never thought of annealed copper shims. Thanks for the video!

Loving the close up shots and camera work. Looking forward to part 2. -Bruce

Great work, really nice close up shots Tom, thanks for sharing!

Looking good Tom! Waiting for part 2 ATB, Robin

Wow Tom, that was pretty slick on the 4 jaw!!!!!

Great video, got me following along waiting for the next installment.

Nice work as always Tom. Going to be a cool tool.

Most excellent.

The drilling portion of this with the big drill is a testament to how much movement you get out of a drilled hole, you can watch that big ass drill flex back and forth

By traveling I thought you meant it was ready to travel here to do some HBM squareness with the world testing. :-)

Great Stuff Tom!!!

VERY nice. Thank you for the wonderful explanation and demo. Now I want to turn some stuff too (ok, I always want to... but I feel the need for a radius turning like you did...) machining is so much FUN... - I'd call it precision art

Nice job Tom.

Love those big twist drill chips. They always remind me of Port Jackson Shark eggs

Thanks Mr. Wizzard !!! Thats What i Call A Stand-Up Project ! Really Cool .

I love the Traveling Squareness Idea . Great Video , excellent camera work. Like they say in Italy -- asta la pasta -- Baby

hey tom, it's me; the guy the complained about the aliasing it's gone now and it looks fantastic

Thanks Tom - great video. Cheers!

I am surprised you didnt leave a square transition to the shoulder and get an assortment of files and file the radius in with your head phones in! lol Good one Tom

Wanted to thank you for all those boring videos on accuracy . I've had this INCA planer/joiner for some 20 years and could never really get it to cut smoothly. If I was really lucky I could get a 90 degree corner. After watching your thinking through various problems (which started out with leveling a lathe) I started to apply such thoughts to other things like that (*^(*&%&^( INCA. I'm making a vibration isolator for a turn table for a friend of mine and needed accurate cutting of very dense wood. After staring at that INCA for a while, I put together a plan and it worked perfectly. I now have flat and parallel surfaces in wood. And now I know how to use that INCA and it turned out to be not that bad of an investment.

It’s gorgeous.

Four jaw dead soft copper inserts will probably come in handy it's one of those i know what I got for that kinda thing good work good to see ya

Enjoyed Tom , Thanks man ! great work..

its good to see chips again. more!

The sisterhood of the traveling squareness comparator

"no need to go Abom on this" :-) :-)

very cool , thanks for the video,,

7:15 awesome cam shot

@ Oxtoolco I've notice here and in a lot of other video's. As a drill enters a work piece it shifts slightly to one side or another (5:10 ish) Is that just and indication of the drill finding center? it seems to me if there is a shift the tailstock or something isn't quite lines up correctly? am I just overthinking this or is there something else going on? WOW the large drill bit is looking like a piece of wet spaghetti.

Whatever happened to the etching press?

To use copper tubes between jaw and work is a great idea. However I always used sudden cooling to make copper for gaskets. Are there different coppers requiring different heat treatments? Thanks, interesting video.

always a pleasure :)

Who doesn't love large drills and lathes. Its nearly as exciting as boring.

Was expecting a track off side two of Dylan's Nashville Skyline :)

As I watched your vid when you used the round insert I recall may times exactly what your talking about ... "chatter" at the shoulder ..... also it occurred to me that another approach may or may not be helpful .... Tubalcains "shear tool" approach ..... BUT .....create a tool holder that will allow the round insert to be angled .....this will allow you to have the full radius or angle it to create a shear tool affect, it seems this might help reduce chatter ..

inspired me ive had a 8" cutoff fot 15 yrs. use it for boring weight on xslide

HEY TOM ! You should be able to drill 1 1/2" in your lathe without the need for a pilot hole. I've drilled diameter 75mm into bisalloy & mild steel without using a pilot in a radial arm drill & 2"-2 1/2" in the lathe with the drill properly sharpened.The drill web needs to be sharpened to a point much like a spade drill. It is easy to do even with a small type pedestal grinder, a boss I had years ago showed me howto sharpen larger drills to do this Flooded with coolant at low RPM so there's no mess.

"Bob's your uncle", i love that expression, even though i have no idea what it means LOL

Hey Tom, great video as always! Question: Shouldn't the indicator mount be keyed onto the vertical post of the squareness comparator? If you inadvertently rotate the indicator around the post slightly, won't that cause a false indication of out of squareness? If the indicator mount was keyed to the comparator shaft, then you would rotate the entire comparator on its base to find the highest reading; then you would slide the indicator up and down, relying on the weight of the entire squareness comparator to prevent any rotation.

A clever design.........but too big for the average user.........perhaps a smaller one would still do the trick using some linear rail for the vertical column.

Do the pieces that you're measuring and the instrument have to be clamped down to the surface plate, because unless I'm misunderstanding something if you bump it a little bit you have to start the sweeping again?

_"I don't want to go Abom"_ lol!

Just for reference to others, this was in Monday Meatloaf 116 P2. kzfaq.info/get/bejne/ar2BpKuTz8vRg40.html

Nice...a little slow in your feeds ...especially in your first roughing cuts...why copper used on hot rolled surface..I'm for getting the job done lol.? Hint...you can quench copper in water to prevent oxidation/scaling=speed...no need cleaning.

What is the point of the copper pieces when you hold hot rolled stock ?

for some reason I thought that the base would have been made of granite. Big chunk with a nice bore hole to take the shaft.

The shot at 7:15 is quite hard on the eyes.

Your center looks like it walked, which carried through the whole drill cycle.

When you mentioned hardening, Do you mean case hardening?

Woody Woodrow

New camera Tom??

Or I know how to make a copper soft jaw. Sweet!

i turn stuff just to watch the chips and smoke all the time :)

What insert type are you using in that boring bar? Looks like a positive rake trigon, which I didn't know existed.

Have you ever noticed that you have a nervous habit of starting 75% of your sentences with the word "So"? I'm not sure why you have picked up this habit as you're a very effective speaker in general. You communicate your thoughts well and help us understand a lot. Just an observation.

why 8620?

What did you use to pack the air bearing?

@6:30 That's what she said. Sorry.

Tom,

6:29 is all that wiggling in the drill actually the drill or is it the camera being affected by the vibrations?
