Adam, I never fast forward your videos, especially when you are doing some odd ball indicating. Seeing is learning. If you ever feel the urge, you would make a fine teacher in a tech school. I learned this stuff in the late 70’s early 80’s in high school from a bunch of WWII navy guys that prolly forgot more than I ever learned from them. You keep on indicating work and showing the process in real time. I’ll bet dollars to donuts that there are teachers that use your videos to teach the old ways to students because they don’t understand the process themselves.
The tediousness of indicating must be shown to give those who are not aware of the extra time it takes beyond making chips……it’s part of the time & effort that needs to be factored in for cost & time estimates. It’s also awesome to see an experienced machinist process which we can all learn from. Keep doing your thing Adam, & thanks again for sharing the knowledge no matter how seemingly boring it may be, it’s just part of the process.🇺🇸👍
I really appreciate the indicating footage, it's so good to see because I know how time consuming it can be and how important it really is. I know it can be monotonous, but necessary and personally I think it's so important to see what it takes. lol especially when you accidentally go the wrong way and have to start all over...a machinists Murphy's Law "when you are at the very last half-thousandths, you will move it the wrong way"
"Indication section can get a bit long".. hey, that's what the channel is about. To take two random pieces of scrap and always make sure they are square and straight and level to less than 1/1000" (approx 3/100 mm).
I was wondering for so long in the previous videos "Is it really worth all this setup of the drill? Couldnt he just drill it to an inch or so and take a 'little' extra time boring?". Then I saw the number of parts on the pallet at 22:51 and I understood just how much time all that coolant setup, pinning, and drill setup was saving
We would do that job at our shop in Ohio but we would do it on a horizontal boring mill. If I was doing it I would rather have all the material in the back already removed so it would actually be boring a through hole. Not near as much indicating required on a boring mill. Just lay it on its side on the table and place that long side up against the table keys. Then clamp over a solid area so it doesnt distort when you drill the hole. set machine spindle to the center hole and drill and bore and done.
If you have a CAD model of the workpiece (approx) then you can easily figure out the approximate center of mass and then based on where radially you want to locate the counterweight you should be very close and then adjust manually afterwards. I've used this type of method and it has worked very well. Just something to think about for your future projects. As usual your videos are amazing and very informative!👍
😮 It's a process that you will do every time when it comes to oddly shaped parts you'll put into a lathe. Since you have to do multiple pieces of the same shape I liked that you made counterbalances to help the machine plus helping keep the borehole from being egg shaped. I definitely enjoyed your show and I know you and Abby have things to do and places to go when you two hit the road but I wisk wish you could have taught would be machinist the knowledge you have like in a trade school or co-op. You're passing it on now. Keep it up.
That huge drill removing metal at .006 feed rate creates tremendous physical forces. The pressure is trying to bend the lathe bed upward and rotate the carriage clockwise while it’s being pulled toward the headstock by the lead screw and gears. That’s why a lathe like this one must be built extremely strong and heavy.
I enjoy seeing you run a lathe . I like knowing what the end use of any parts being made are for but I understand if they don’t want to say . Still made a good video. Thanks Adam
So I had a part where I was told they wanted a slip fit for bearings. We did that, but they then found out that the surface finish wasn’t good enough. Now whenever we’re dealing with anything they deem a “slip fit” we make them give a call out for over all size and surface finish
The lathe gears sound way, way better with the counterweights bolted on. I've been waiting for this video since you put this on IG a wile back. Cheers!
I'll tell ys guy, I'm ssoo happy to see some real payin' work come in. A business owner needs income or pretty soon no business. I've been down that road. Damn good video.
G'day Adam. Thanks for taking us through this type of very awkward meticulous job. It is food for thought in the event we come to any job , that might even come close to what you have taken on. Very complex in setup etc. Job is working really well especially with the baring train fitting so well. Thanks Ted
If you want to be more finicky balancing, add one of the hold down clamp bars on each of the balance studs. Then slide in/out to adjust. Just a thought, not a complaint!
I would suggest increasing the diameter of the pipe coming out of your coolant pump for as far as you can, if not all the way to the tool. That pump can likely provide you with more volume of coolant if you reduce the restriction of the small discharge line. The line can be larger than the outlet of the pump and you will get better volume at a lower pressure.
Was a machine tool setter operator for 50 years now retired,never understood how you manage the price per workpiece when you own a business,especially when you have an awkward job as this one, be interesting to find your method,but at anyrate keep up these videos very entertaining
Now that you have coolant on the APM … it looks like a plexiglass back splash might come in handy to keep splash off of the wall and circuit breaker box
I love your vids, I'm not a machinist, never used a lathe. But I find it fascinating how you "dial it in" with the indicators. Those coolant fittings look like (or similar to) air fittings
Abom its surprising to me that after all these years you still have not made a brass shim clip on cap for your jaws that would make it easier to indicate if the same piece of shim is on the same jaw for this job
How long did it take to drill and bore each item, from getting it off the skid to back on the skid finished? Looked like a fun project. You do beautiful work. From Missouri
Adam , If you decide to upgrade the pump for the coolant on the pacemaker, try to get a pump that resembles an oil pump for an automobile. You might even be able to get a used one and adapt for motor attachment.
Was thinking while you were balancing the chuck. Given the specific weight of material, couldn't you measure the area of offset material, then look up the weight of a given area and do some math to get pretty close for the weight needed to offset the balance?
I just love it when you do the manual maching and watching you center a piece is all part of it. Don't get me wrong I know that you are working to do more CNC work and I applaud you for that endevor and you are learning it very well. I just enjoy your manual work so much more and have learned a lot from watching your manual work. Thanks for what you do and your teaching.
You have a flow not pressure problem with the coolant. You need high flow connectors not standard air connectors. Higher pressure would also work better.
Abom79, Do you think, a Faster Flowing Coolent, would work better, at A Higher Feed Rate?. For a better Chip Colour?.. Maybe, a more Powerful Coolant Pump?..
That center hole in the end face must not necessarily be centered side to side or up and down in the parts, given how much you had to move the second part around to get the hole centered. That looked a bit alarming. Maybe it doesn't matter, but it would have been nicer for you if the previous work had a bit of consistency to it, part to part. Might be worth a look through the rest of the parts and check hole locations and group them so you don't have to chase them back and forth across the face of the planet. I love 4-jaw work as much as anybody, but moving parts around a bunch because the previous work is all over the place. Thanks for the video!
I was wondering about the disparity between #1 and #2 as well. I would be curious to see a couple set up on the surface plate and compared a .125 difference seemed a lot to me. Hey Adam give us some metrology.
I was a little worried about that too. Can you imagine if he finished them and sent them back to the company and they said they didn't work cuz they were off. Not because of anything he did wrong, but because they put the center marks wrong. I would send back the first couple and make sure they work before he keeps doing more.
He watches the same video over and over again as he edits the video. I suspect that they aren’t finished, or they are not all identical. I’m confident that he would have noticed the error.
Since the metal you're removing is a cylinder along the axis of rotation, the correct counterweights will not change as you do the machining. (Says a fairly good math teacher with NO experience whatsoever in handling such large, off-centre rotating masses)
Look at the ratio of mass removed from the lighter side vs the heavy side. It does slightly change the ratios. Honestly moving the counter weights in about 1 inch would be enough difference to make a better/worse balance.

A 1 hour long video of Adam doing his finest, YES PLEASE, give me more of this!!

Adam, I love how you honor your Dad and Grand Dad at the end of your videos with the pic of the three of you.
Adam you'll always be "Indicator Champion" of TH-cam machinists . I think we can spare a few minutes to watch the master.
I really appreciate the indicating footage, it's so good to see because I know how time consuming it can be and how important it really is. I know it can be monotonous, but necessary and personally I think it's so important to see what it takes. lol especially when you accidentally go the wrong way and have to start all over...a machinists Murphy's Law "when you are at the very last half-thousandths, you will move it the wrong way"
It is tedious for sure. Especially when you are doing work that is better suited for a horizontal boring machine on a lathe.
"Indication section can get a bit long".. hey, that's what the channel is about. To take two random pieces of scrap and always make sure they are square and straight and level to less than 1/1000" (approx 3/100 mm).
Indicating is prep work for machining just like you do for painting the better the prep the better the paint job
What a great show. Old school machining rocks. Superb filming. Thanks
"only 13 more to do" That's a huge job and a lot of work. I hope you're being well compensated.
From father to son, you get the job done. Great skills.
Looks great Adam. You just proved what I tell people all the time, set up is the lion share of the machining process most of the time.
UR setup works good - Thanks for showing
Taking the cut is easy, it’s always setup that takes time, and it’s worth it!
I was wondering for so long in the previous videos "Is it really worth all this setup of the drill? Couldnt he just drill it to an inch or so and take a 'little' extra time boring?". Then I saw the number of parts on the pallet at 22:51 and I understood just how much time all that coolant setup, pinning, and drill setup was saving
I love every minute of your videos. Feel free to share the details. I consider these to be instructional videos.
We would do that job at our shop in Ohio but we would do it on a horizontal boring mill. If I was doing it I would rather have all the material in the back already removed so it would actually be boring a through hole. Not near as much indicating required on a boring mill.

Then clamp over a solid area so it doesnt distort when you drill the hole. set machine spindle to the center hole and drill and bore and done.
Many ways to do a job, one isn’t better than another, just different.
This job was a classic boring mill job if there ever was one - but apparently no one with a boring mill wanted to do it.
Dam hearing that old iron working with a good load on it sounds so good
Love the way you think Adam
Love the sound of a lathe when it's under a constant load
Great job like watching Thanks Happy Thanksgiving
What a wonderful bandsaw cut!❤❤❤❤❤

I know that the counterweights had to be faced, but I am still amazed at the cut quality of the band saw blade.

The pressure is trying to bend the lathe bed upward and rotate the carriage clockwise while it’s being pulled toward the headstock by the lead screw and gears. That’s why a lathe like this one must be built extremely strong and heavy.
seeing that chuck wrench handle flex must've be like what, 2.3-2.5 abom-torque 😉
I enjoy seeing you run a lathe . I like knowing what the end use of any parts being made are for but I understand if they don’t want to say . Still made a good video. Thanks Adam
Looking good kid! You're a master craftsman and you deserve every single subscription you have. Thank you so much for sharing with us.
So I had a part where I was told they wanted a slip fit for bearings. We did that, but they then found out that the surface finish wasn’t good enough. Now whenever we’re dealing with anything they deem a “slip fit” we make them give a call out for over all size and surface finish
A slip fit is a defined standard depending on diameter. If they complain about a surface finish they should have defined one.
@ trust me I didn’t agree with having to re-make the parts. But ultimately boss man told me to remake the parts so I did.
The lathe generally sounds much happier now you've balanced if properly.
That's what I was thinking
Adam, you’re a Prince among machinists. 👍👍👊👊👊
I love you Abom.......Ur an awesome person.
The lathe gears sound way, way better with the counterweights bolted on. I've been waiting for this video since you put this on IG a wile back. Cheers!
Great work. I like your problem solving skills.❤
Wow, Adam that was amazing, great job. You are a legend. Thankyou.
Ok, who else sees Scrat the little squirrel guy from the " Ice Age" cartoons?
I'll tell ys guy, I'm ssoo happy to see some real payin' work come in. A business owner needs income or pretty soon no business. I've been down that road. Damn good video.

Nice to see you use your skills
Abom moving some metal and having some fun doing it!
This drill is like your content: Awesome!
And now Adam is in the market for a nice horizontal boring mill Josh Topper has.
As the crow flies Josh is closer to Colorado than Adam is. I'll bet Josh would love to have this job.
If you want to be more finicky balancing, add one of the hold down clamp bars on each of the balance studs. Then slide in/out to adjust. Just a thought, not a complaint!
Excellent job on a very challenging job!!!!

I was really wanting to know too. 300 a hour, 8 hours x 12, plus 30%. Plus 1000 for tools. Plus 1500 for delivery. No clue
Another great job Adam. I love these videos and keep em coming!
More American Pacemaker content please 🙏
Wicked Work Adam!
I can’t imagine the torque going into that drill. I would be standing on the other side of the shop waiting for it to explode.
Thank you for sharing
Dude, you had me screaming at my phone...just slide them away from the axis!
😂🤣😂🤣😂🤣
Now that you have coolant on the APM … it looks like a plexiglass back splash might come in handy to keep splash off of the wall and circuit breaker box
Can’t beat Abom when the weathers nasty and cold outside
Nice Job, Adam! All that prep time over these last few vids has really paid off. It's nice when a plan works as intended.
Could you have moved the weights in and out to adjust for the center point of the mass?
I believe the answer is yes, but would an inch be enough? There's not much additional space.
@ very true space is indeed a premium here
I love your vids, I'm not a machinist, never used a lathe. But I find it fascinating how you "dial it in" with the indicators. Those coolant fittings look like (or similar to) air fittings
That's gonna be a whole lotta indicatin.
nice way to spend some time during a blizzard Adam thanks for the tech tips and entertainment from the great white north
35:00 Yes Adam, I enjoy the precision work that you do.
Tres cool Señor Abom
Holy Cow! That was so intense! And you've only (only!!) got 13 more to go!
Remember when the 'sky hook' was a fictional device like 'muffler bearings'?
Fine job Adam, keep breathing 😀
Abom its surprising to me that after all these years you still have not made a brass shim clip on cap for your jaws
that would make it easier to indicate if the same piece of shim is on the same jaw for this job
With the counterweights added, it looks like Johnny 5 from that 1986 movie…
How long did it take to drill and bore each item, from getting it off the skid to back on the skid finished? Looked like a fun project. You do beautiful work. From Missouri
I'm a little disappointed. All those chips and no salsa?😁😁
Adam , If you decide to upgrade the pump for the coolant on the pacemaker, try to get a pump that resembles an oil pump for an automobile. You might even be able to get a used one and adapt for motor attachment.
The pump he is using would be ok. It's the hose that is too small ID and all the 90 degree fittings that is reducing the output.
Was thinking while you were balancing the chuck. Given the specific weight of material, couldn't you measure the area of offset material, then look up the weight of a given area and do some math to get pretty close for the weight needed to offset the balance?
I like it!!!
@AbbeyRoad6914 At least he checked the sides after doing the centres this time!
I just love it when you do the manual maching and watching you center a piece is all part of it. Don't get me wrong I know that you are working to do more CNC work and I applaud you for that endevor and you are learning it very well. I just enjoy your manual work so much more and have learned a lot from watching your manual work. Thanks for what you do and your teaching.
I am not surprised that no shop wanted the job. The pieces are too big for a small shop and there are not enough pieces for a large shop.
Would a dial bore gauge be as accurate to measure the bore size as the telescope gauge?
More
THAT was fun.
That would be a great horizontal spindle job.
I'm nervous on this side of the screen with those counterweights bolted on. One of them coming lose might just ruin a fellas day.
You have a flow not pressure problem with the coolant. You need high flow connectors not standard air connectors. Higher pressure would also work better.
Like some full flow QC's from Swagelok.
The lathe sounds so much better now that you have the counter weights on .
Finally found that sky hook I’ve been looking for 😂
Am I the only one that sees a happy train face with a big nose between the finished part, the counter weights & the chuck? 🙂
Abom79,
Do you think, a Faster Flowing Coolent, would work better, at A Higher Feed Rate?. For a better Chip Colour?..
Maybe, a more Powerful Coolant Pump?..
this was my question (before seeing the vid)! I thout you'd have a maths configuration! I was just (ignorant) your the best bro.
I hope we see a new project next week
That center hole in the end face must not necessarily be centered side to side or up and down in the parts, given how much you had to move the second part around to get the hole centered. That looked a bit alarming.

@@janj0n Final machining will probably be set up by the bored hole..only way it could work unless accuracy doesn't matter.
I was a little worried about that too. Can you imagine if he finished them and sent them back to the company and they said they didn't work cuz they were off. Not because of anything he did wrong, but because they put the center marks wrong. I would send back the first couple and make sure they work before he keeps doing more.

No way I'm this early. Never happens. Hey Adam, hope you're good
i was almost killed by a weight on a chuck that came off , so every one be extra careful ,thank you
That Sky Hook company should put a nice battery motor on that thing, with a nice push button control cord🤷🏻♂️🤷🏻♂️
Abby!
Abom79,
I also Noticed, what Sounds like, Your Shortness, of Breath. With All Do Respect. Take Care of your Health! Please.
GOD SPEED
FYI Milton makes them, as do some thers.
the part kinda looks like a mag drill
Where's the painted hardtail vise?
Since the metal you're removing is a cylinder along the axis of rotation, the correct counterweights will not change as you do the machining. (Says a fairly good math teacher with NO experience whatsoever in handling such large, off-centre rotating masses)
Look at the ratio of mass removed from the lighter side vs the heavy side. It does slightly change the ratios. Honestly moving the counter weights in about 1 inch would be enough difference to make a better/worse balance.
Interesting point.
Why spade drill vs twist and boring bar?
He had a spade drill that big.
Sounds better 2nd time
How much it's Weigh before drilling?
Using the magnetic lifting devices as counterweights on the part or the chuck? Enough strength?
He would need 2 extras. Besides there is no way he would trust those expensive magnets for that.
How will you know exacly how mutch weights to add to counter balance ? Just asking.
Love your vid your so precise best regard to Amy your wife.
