Abom79 Parking Attachment! Part 2 Widget96

[@Abom79]

Can't thank you enough John!! You did a great job on this part, and again I enjoyed how you shown different aspects of the machining, even how you indicate a part in your machine. It's gonna look great mated up to the parts I'm building. The delivery was freakin awesome!! I'll be sharing of on my end soon too. 👍👍

[@johnferguson7235]

Next time, wrap the part in bubble wrap and put it into a bank safe and strap it on a pallet. Really important parts for important customers require maximum protection.

[@isabellaman2545]

The learning mistakes. Worlds best teacher. Watching someone else's are almost as good as your own. Great vids thanks John

[@CatNolara]

Is that a joke? I don't understand...

[@dejanbrice8774]

Yes, Adam likes to package stuff up in strange ways also. It's sort of an inside joke between a lot of them.

[@derKarl_stp]

this is much more than just a joke... you know Adam aka abom79 has some large machines and tools he works with... so several viewers sent him some "Abom sized tools" (tiny little ones)... like mini hammers, mini endmills and Tom Lipton (Oxtools) sent a "precission level" one day... ...so John made the package for delivery become "ABOM-SIZE" as well ;-) I love that sense of humor John :D

[@CatNolara]

That's really kinda funny, and I do remember the "precision" angle from/for (?) Tom Lipton, that was hillarious :D

[@GregsGarage]

HAHA!!! I'm glad I stuck around of the end! Interesting to see the mistakes (added design features). That type of footage helps guys like me think through the whole operation.

[@GeofDumas]

"machining is really easy... until you have to fixture shit" I'd like that on my wall in needlepoint

"It is pleasant, when the sea is high and the winds are dashing the waves about, to watch from the shores the struggles of another." Im still baffled and surprised when I manage to make a part on my hobby mill without any mistakes. Its real comforting to see that others makes mistakes too.

Engraving on a slope..I'm impressed...!

[@markanthonysmith413]

Great Job John, we've all had bad days at the shop when everything you touch goes wrong but you got there and like you said what you did to fix things won't affect functionality. All the best Mark.

[@johnferguson7235]

When I worked at Rockwell many years ago, we got one of the first CNC machines. During our breaks, we would go stand around and watch it work like we were watching a TV show. It felt like being in an episode of Star Trek. The software, written in FORTRAN, was loaded onto reel to reel tape. It was a big deal when they upgraded to 8" floppy disc. It's amazing to see how this technology has become so common place and so accessible to small businesses.

[@johnferguson7235]

NYC CNC The other mill used punch cards to program.

[@tsgsjeremy]

Came over from Abom's channel. Glad I did. YOU now have a new subscriber, and I now know how to properly palletize hand crafted steel. :)

My Boss Told Me, "It You Never Make a Mistake, You Ain't Doing Nothing." Very True. Great Job!

John, mistakes are what makes us keen learners, what is it they say "Best is the enemy of Better'. Awesome, honest work, who could ask for more. Regards from a hot sunny Scotland.

[@Nikkuuu69]

I had a blast watching this! Thank you so much for filming it in such great detail.

[@paulrussell623]

Good stuff John, I really aprieciate the warts 'n' all approach you took on this job, ie. showing mistakes and not just editing them out. Cheers, Paul.

[@Joesmith-pl4qb]

Another awesome video! I really like the fact that you present it as it really is. Thanks for taking the time to video this for us!

[@RobertKohut]

Great video series. Complex machining takes a prototype to get it right so you did pretty good considering. If don't make mistakes, you don't learn! Loved the shipping!!! Looking forward to seeing it in the ABOM79 shop!!

[@HughesEarthworks]

Tons a great info in this series John. I really like the hose as an indicator for changing the feed rates. That has bit me when I forgot I changed them to 150%.

[@demonic477]

I have to say his palettization is spot on it's literally iron worker 101 and funny as hell . as a former iron worker back in the late 70's it's the little touches that make it so damn funny it one of the reasons I miss the old mills so bad.

[@TimeWasted8675309]

Loving this series John. Nice to see the fixturing challenges - and the corrections of things that didn't go perfect the first time. Lots of eyes on this project too so maybe understandable nerves and your desire to do a great job. I had a late job last night of pre-formed and anodized aluminum frames that needed some precise shapes milled.. late night, customer watching, only 1 change to get them right, big pucker factor - broke a tiny endmill due to fixture vibration.. all part of the job ;)

[@spfldmilkman]

Very nice showing of milling with tons of step by step information. good stuff

[@rchopp]

It was nice to see it come together, loved the engraving and the shipping was over the top..lol

[@stahlinstudios2067]

Interesting point about small end mills. My neighbor at the shop is a mold maker, he is always cutting super fussy parts out of hard steel (p20, H13). He has a brand new HAAS VM-2 and he cuts some large parts but he is always using small end mills (1/4, 3/8) and taking light fast cuts. It seems counter-intuitive but it seems to be an effective strategy. (time, cost, and machine wear) Thanks for the videos!

[@commadore129]

Hey John that part looked nice. But if I was to make that part, I would bring it over to the Bridgeport and square all sides to finish dims. first. If it really had to be close then i would check it on a surface plate and use a ground step block to check square first. Then you know it's to size and square so that when you flip it and indicate it that it is parallel. Also don't bother using carbide roughers you don't have a big enough machine to make it very efficient. H.s.s. roughers will work fine as long as you leave 0.010" - 0.020" to finish with. But if you square in in the Bridgeport using a 2-3" dia. face mill you can take .100" off in a pass easily. Just figured it might help in the future. Great work nice finish I think Adam will be very happy with it. I do a lot of job shop work like that. I started out doing 3D work all on a Bridgeport mill no cnc and I learned how to be fast an efficient the hard way lol. Now most of the time I square them on a Bridgeport then grind if needed then run them on cnc. I think a lot of people forget keep it simple is best way most of the time. Any way good job and keep up the good work!

[@JustinAlexanderBell]

Nice palletizing job. :D

[@baccus61]

I was just thinking how far you have come from that tiny little basement to a fully fledged CNC setup and huge workshop. Well done. Keep up the great work and keep the interesting videos coming. :-)

[@tsw199756]

Just a thought but if you milled the 2 finished boss faces and put the thru hole in one and the tapered/straight slot in the other. Then set up a aluminum pc in the vise and milled 2 matching bosses to locate the part and clamped thru the hole and slot you could have machined the whole outside and remainder of the top in one setup. then flip to cut the bottom step. I believe that's how I would have tackled this project but anyhow nice job John it's good to know I am not the only one who struggles on occasion. I was always taught that the only time a machinist hurries is when he has made a mistake or is about too! LOL

[@TomZelickman]

Nice touch there at the very end, John... They guys next door were good about it too! I think the part come out very nicely and I'm glad to see you left the footage in that was less than optimal"... Best wishes and say Hi to Jared for me! Tom Z

[@StefanGotteswinter]

Wrong Z height? "Who does that" - Happens everybody :D

[@barrythompson8813]

Love the 'shipping'process at the end ! You could almost have a horizontal dumb waiter setup with Fedex next door :-) Also appreciate the fact that you picked up the height error because you do carefully QA your parts before shipping/

[@ericallen1045]

Haha I needed that laugh John great ending!!!! Can't wait to see if Adam fires up his forklift or just throws the pallet over his shoulder

[@NCPDFSB]

nice job john, shipping was extraordinary!

[@ArcAiN6]

I like how you move from CNC, to manual on your "drill press" :D Not sure if it's just preference or not, but you don't need to move to 0 when sweeping side to side after every sweep, you can just tap your part until the sweep matches on both sides, then 0 and double check.. would save you some time while tramming parts.

[@ArcAiN6]

That's why i asked if it was just a preference. I know time is money, and every bit of time you can save adds up at the end of a job :)

[@matthewlepper3662]

Who forgets to set their Z-height correctly? Everybody at one time or another, at least you didn't screw up in the wrong direction. Another possible reason for the "leftovers" on the adaptive tool path: if you used a tool with a corner radius, but created the tool path assuming a square corner, some bits could be left behind where the overlap between adjacent tool paths is less than 2x the corner radius.

[@charlesbradshaw1285]

Nice job Jo. One small detail though. Those gauges are Jo Blocks in the US or Slips in Britain, A height gauge is something else entirely.

[@petert6103]

When you were dialling in the underside of the part - the pressure that was relieved when more material was removed from one side of the part had caused some warping.

[@waiakalulu1568]

We would ACTUALLY DO THAT sometimes when we were shipping telescope instrument parts, otherwise things are smashed to bits and crumbs out here in the Pacific Islands. If they don't put their mitts on it, things go a lot better.

[@harrisonkatzz7090]

MERRY NEW YEAR . JUST SAW THIS RECOVERING FROM AFU IS THE BEST TEACHING ! THANK YOU .

[@mattcurry29]

Nice shipping job. The part looked great.

[@johnbazaar8440]

When we drill holes on cylindrical or other non-flat surfaces, we always spotface before drilling. That prevents drill drifting and breaking taps. There's not much material strength lost. I've also noticed that your cam program creates g-code that cuts a lot of air. I hate cutting air, in case you haven't noticed. Not a big deal for simple parts but for bigger, more complex parts, it starts to waste time and money. As far as tool chatter is concerned, I think bigger is better. If I have a choice among 1/2", 3/4" and 1" end mills of about the same length and I have room, I'll pick the 1" end mill every time. Just curious, do you have a tool height setting fixture? A little constructive criticism. Nice project. Adam will love it. Thanks, John

[@rtwolfrt]

Great video, really appreciate the fact you left in the few mishaps.

[@GlassImpressions]

I would be curious to see the difference in quoting the job between the two methods: CNC vs. manual milling.

[@lincolnmetal1]

there are too many variables involved really...its all up to the programmer and machine for the cnc work. a guy with a cat 50 machine is going to knock this part out in fractions of the time than a guy with a cat 30 or 40...nature of the beast really.

[@DougHanchard]

Brilliant delivery planning. Had I known, I would have made sure Fed - Ex delivered it to Adam's shop with a double A-train and Class 8 Rig. :)

[@ronkluwe4875]

John; Very nice. Was waiting to see if you were going to do something with the packaging of the piece. Nice touch with the pallet. Any weird questions from the FedEx guys? Did you ever figure out what caused the extra pocketing in your tool path? I am just getting into Fusion 360 (using your tutorials along with the Autodesk tutorials) and appreciate seeing someone else figuring out some of the not so apparent issues. Regards; Ron Kluwe

[@StevenRosburg]

Awesome job! I loved seeing that 5-flute end mill in action, it eats steel like it's a snack and leaves a beautiful finish at the same time. I really enjoy seeing both the perfect and the not-so-perfect, and how you adapt and adjust to correct mistakes.

[@travisshrewsbury7169]

boy is Adam gonna hate it when he gets the bill for that! lol Looks great,love the shipping

[@THEmikeVDW]

I use a wee 1mm ball nose to do engraving and It works beautiful. doesn't raised a burr edge and looks great worth a try sometime...

[@THEmikeVDW]

Keep up the great work, i enjoy seeing what parts the shop is crafting.

[@brandonl.5998]

"Machining is really easy till you have to fixture shit." Agreed! Learned that the hard way with my desk project.

[@DjMalaVida]

you could also use a ball endmill to engrave. No bur at all and it leaves a great finish too. Good video

[@kopsik111]

When tramming the part there is no point in zeroing your Haimer every time...just keep sweeping left and right until your get the same number across the part.

[@garyc5483]

The part will look great when assembled with the rest of the fixture. Great packing. I hope they don't stack another pallet on top. :-) regards from the UK

[@alphgeek]

I wonder if you pushed your carbide tooling harder (faster RPM, higher feedrate - same cut per tooth and WOC/DOC) whether it would reduce the chatter you got coming around the round ends of the part (mostly the roughing endmills in part 1 but also a little bit on the 3/4 inch endmill in part 2)? It'd be interesting to see how much spindle power you had up your sleeve, if any but I don't think you have a power meter installed on that machine? It seems a bit counterintuitive to suggest harder milling to reduce chatter but that's what I see, albeit in turning operations rather than milling - I up the RPM and feedrate when I get chatter and it usually improves. As a side benefit, the faster RPM also tends to give an even better surface finish. I imagine those endmills would be up for it as much bigger machines can drive their tooling harder. Great job overall, the part came out looking nice. I was very impressed with that ball endmill.

I am really hoping the pallet for the box and the loading it in your truck to go 20 feet was an inside joke.

[@JaakkoF]

Rezeroing that X axis location on the hole center isn't necessary the second time, as you have a round hole. It was centered the first time you did it and it isn't getting any better by doing it again after the Y.

[@brosselot1]

John very very good work. Very cool

[@jonathanbatson6541]

I would be interested in seeing how you inspect these parts. I'm a metrologist/QE and have always be curious.

[@jkotka]

for that drilling part, maybe come in from the side with an end-mill to create a flat, then spot it, then drill it

[@gordonmorse663]

Why not drill that feature first so you're not entering on a slope/curve? Bear in mind I'm a noob so I'm interested if there is a good reason not to. Thanks for educational videos!

[@ianide2480]

Drilling it first before the contour is exactly what I would have done. I have used this method on more than one occasion.

[@PeterWMeek]

I was wondering about the finish pass around the outside. It seemed like a lot of the chips were being pulled around and recut. I always thought that was supposed to be bad for the final finish, but yours seemed to be just fine. Comment?

[@Dan.Whiteford]

Great pair of videos and as said previously quite fascinating to watch the whole process. Question: What did you personally learn as it would appear that you are unaccustomed to working with quite such large work pieces? Don't you have half / quarter size pallets in your part of the world!!?

[@kenwolfe6093]

The large pallet was done purposely. There is a packaging/shipping thing going on between the KZbin machinist/creator family. It's all in fun.

[@DonDegidio]

John, Another very well done video. I watched it just shortly after being uploaded, but my computer went down before I was able to comment. Glad I made a complete backup Monday evening. :-) Did you measure the reamed hole to determine if the diameter reading was close when you flipped the part over and used the hole to register the part? And as others already mentioned, like the pallet used for shipping that sized package back to Adam.

[@MrJoarek]

When you speed up the clips, could you add a indication for example x4. Nearly soiled myself when it speeded up on the finsihing pass and braced myself for a crash :p Cheers!

[@adamcain4603]

Setting the wrong Z isn't embarrassing at all, I was setting a new tool up and added an extra inch into the cutter comp settings. I pressed the go button and the first move was a rapid movement above the part. The tool dove straight down into the work piece scarred the crap out of me.

[@Sonic_Shroom]

I like how you made it lock like you spot faced when you forgot to spot face.

[@meandmycnc1644]

late to the game here SMW...but this is great for us beginners to see how you progress...and see where you are now!!!

[@occamssawzall3486]

Side note. When tramming with a haimer. DO NOT bring the needle to the 0-0 mark. Only bring it to the first 20 thou mark. Running the probe when it's under full tension like that will not only cause inaccurate measurements but will damage the internal mechanisms.

[@animalmother2242]

interesting... when dragging the tip you want the tension on the weak side?

[@occamssawzall3486]

+AnimalMother224 Yes. It's still measuring. If it's at full tension the force will cause the probe to drag and lag behind in the opposite direction you're moving it. Causing errors in its reading. Example if you're traming X straight. You only want it to be measuring in the Y direction. At full tension it'll measure in X and Y as the tension on the tip will drag against the part. The less tension against the probe the less drag on the tip. And the less error will incur.

[@Warmachinellc15]

yes that's what I do as well. I just use the first 5 thou. still not as accurate as a DTI but usually close enough.

[@occamssawzall3486]

+Occams Sawzall In fact right in the haimer manual (which I'm sure few people have read lol) it specifically says to do it that way. It also describes the way to use it to center up a hole. Which is -X to +X. Halve the distance measured. . +Y to -Y Halve the distance measured. Then +X to -X and halve the distance. So John actually did that correctly :)

[@animalmother2242]

instructions? HA! thats adorable :)

[@MrToolsofrenewal]

You went to all that trouble and then cheaped out on the shipping.

[@occamssawzall3486]

Ok. Now I really wondering here You have a roughing endmill and a finishing endmill capable of reaching the entire height of the part. Why not rough and finish the outer profile and the slot all in op 1? Then op2 and side hole as normal (minus the botch on the side hole ;) ) Coulda skipped that fixturing nightmare completely PS. Called it on the part prone to wanting to rock and not line up flat doing Op2 that way ;) Least you got some alignment practice outta it.

[@occamssawzall3486]

+NYC CNC the largest strongest tool that was taking the least material off was the one you most worried about?? :)

[@sachie123]

That pallet cracked me up ..john.

[@63256325N]

Nice. What'd the guys at Fed X think of the whole pallet deal? I didn't think it was actually strapped down to it....lol

[@63256325N]

Really? I guess Fed X has absolutely no sense of humor. It's all about the cash.

[@kopsik111]

Oh and to avoid those Z height mishaps when flipping a part I usually measure the Z height from parallels or like in your case from the vise and then just lift the offset the amount of the part height. And still even average quality carbide end mills need way more RPS-s. For steel a 6mm endmill needs about 9500rpm and 12mm 7200 rpm.

[@MrLiamCooley]

You could always indicate the underside of the lip with a test indicator on op2. then stick a jack under the other side to adjust it to zero.

[@RichardCournoyer]

Can you teach a newby about your method of shipping? I assume the pallet was to add an extra layer of protection. What is the cost of shipping via a pallet vs a larger or maybe a double box? Thanks.

[@kenwolfe6093]

The overdone packaging is a thing between the KZbin machinists/creators. I think I remember that Tom Lipton started it by shipping a welded steel box to Adam that had to be cut open on the mill. It just keeps going from there........

[@proten40]

Good looking son! When in August is the baby due? I have my first grandchild (Grandson) due end of August, first of September.

[@DoNotAuthorize]

Wow. That was brutal. I fixture in Solidworks.

[@bggwrks2503]

Heyho If you use a 3D- egdefinder, it's allways better to move the whole way back out of the measuring range, if you overshot the zero. Because even the best of them act with some sort of backflash, check out the manual maybe this thing is blessed with no hysteresis. Most times it's not that much, less than 0,020 mm I'll guess, but it will be disturbing, when it comes in use to measure something like a precise hole diameter.

[@r.j.sworkshop7883]

I find that it is best to make a mistake on the part that gets the most attention. That way everybody can see it. Looks like you have that down. Great to see that it made the cut.

[@sytherpka]

You don't need to re - zero the x, it will still give you the exact centre point just from touching 2 points on the hole if they are exactly opposite.

[@occamssawzall3486]

For what he was doing. No. But it's good practice to re zero the X like that, especially if part has fussy dimensions. Though to be honest I'd never use a haimer for locating like that. I'd tram with a test indicator.

[@tizwicky]

Good stuff, well worth the wait!!!!

[@btcbob11392]

Is that a " Cool Mist " system ?

[@eformance]

If you use a 1/2 EM for the uphill milling, you can get smaller scallops with a larger stepover than with a ball mill. Try simulating it and you will see what I mean.

[@eformance]

The closer to vertical you go, the closer the cut becomes to that of a ball mill. The closer to flat, the larger the effective radius becomes.

[@Zaphod7835]

As a lover of all things mechanical, extremely interesting and impressive machining.... but what the hell are these parking attachments for?

[@jimzivny1554]

I was laughing so hard I was in tears at the end. Seriously, I truly enjoy your videos, I'm almost 60 and my idea of hi-tech is a digital caliper however watching you create is amazing, the finish on the parts is great, I'm sure the accuracy would be hard to match by hand. Thankfully my sons help keep me somewhat up to date(although I hear the term "Dinosaur" occasionally) and a DRO is probably in my future however I've learned a lot from you and your videos, thank you. One question, I'm used to using quite a bit of coolant and during the making of Aboms part you only had a very fine mistake, is it because of the carbide? Also the tapping machine you used looks great, any info on that? Thanks again.

[@Xraller]

[@SpencerWebb]

OK... the pallet was hysterical. :-P

[@kenwolfe6093]

I was surprised you didn't just drive the fork truck right over to Fedex. No matter.....it's still very funny. ;)

[@Malorie001]

Same question as last vid. Why the climb cutting? Always like watching the videos.

[@Zkkr429]

Conventional milling is dead. CNCs have the rigidity to take much heavier roughing cuts without the risk of the tool pulling into the job, which is pretty much the only reason you'd conventional mill. Climb milling produces a better finish and in roughing operations it is much kinder to the cutter, especially if your using higher feeds. Think how the clearance is ground on your endmill and where it is in relation to the material when climbing or conventional milling. Climb milling means you have a lot 'freer' cut. Don't take my word for it, do a bit of roughing at the same speeds and feeds going the other way, the tool life will be dramatically reduced. The only time i conventional mill is with a slit saw, possibly with a woodruff cutter, but now we have insert T cutters I climb with those too.
