Abom79 Parking Attachment! TIME LAPSE! 

Nice!

I just wanted to say you do some excellent work, not just in machining but also in your video quality. I dont think I've seen more than a handful of videos, much less accounts that do as good of a job on video quality and production as you do! Thanks for doing what you do mate!

Very cool! You can't help but rouse interest in CNC with videos like this!

As a guy looking to start a job shop / prototyping business it's great to see these kinds of posts. Thanks! Having come out of a large manufacturing business (customer of machining businesses), $700-900 for a one-off part (say a replacement of a broken part of a packaging machine) probably isn't too bad given the cost of down-time on our machines. I know we paid what seems like ridiculous amounts for certain parts (usually in stainless though). But for a prototype part for a small startup or for a hobbyist customer it could be prohibitive. Food for thought for me in deciding where to market myself as a machinist.

John, if there is one person who will appreciate you efforts, it's Adam Both, I know he would reciprocate if the tables were turned. 10/10 NYC, CNC. Go to the top of the class.

CNC work is not meant for one off's. Therefore to calculate that price means it will always be higher than you expected. Manual machining this part will also cost arround 700-900. But, if I ask you to give a price for say 300 the price would be very different. That is the strong point of CNC. But very nice that you have taken the time and the effort to make a fellow youtuber happy.

Adom will be very happy with that part came out very good looks good CNC make things like that look easy John Great video

Despite my fears on the implications of such technology for the machinists of today I simply have to applaud the fantastic end product which CNC lathes coupled with the expert programming of highly skilled operators can deliver. Nice job Mr Saunders!

grumble grumble. RU-vid popped the time elapsed before showing the earlier parts. great stuff!

Cool that you helped Adam out , John. BTW- Your thinking out loud cost estimate is right in the ball park. Customers just don't understand how long it takes to create a part from start to finish. It just isn't about how fast the machine cuts. That's only a fraction of the job. Nice job and finish, especially considering it was 1018.

That piece would make the folks at K & T Proud. Of course from their old cast/forged production it would be far cheaper(read less expensive) but how else would one do a one-off for a piece out of production? Very Nice Work John. Adam will be thrilled & proud and very humbled.

Great set of videos - I'm an avid Abom watcher, love watching the hi tech stuff now as well. :)

great job, part looks amazing. love the engraving that looks just awesome!!!!

Just to have a tool in ABOMs shop, priceless! well, part of a tool. Worth the price at any cost. Besides this was labor of love. Seeing the cam and cad for this part is fantastic. The machining part was a bit fast. I hope we get more closeups of the machining. I am interested in more cam setup, tool selection.

It would be interesting to know what Adam's shop (ie his day job) would charge for a similar part, or what they charge out as their hourly rate. I suspect if they made it the price would not be too different from your estimate. Anyway, it was good to see this collaboration going on - you and Adam use different technologies but in many ways are so similar in attention to detail and accuracy, and especially in both having a professional approach to machining work. Two great channels guys.

John this is how I price my work. I do not price in conversations with the client about what they want, unless it is after they sign off for what they want. Design is not quoted if they are providing parameters and not asking for design. Honestly this is a 30min design job. tool paths hmmm depending how good you are at tool paths. For this say an hour on tool paths. I quote for proficiency not my lack of capability. If I take 5 hours because I can't figure out the tool path but a good designer would do it in 45mins I charge 45 minutes. I want more money? Then I get better. This is a $300 part assuming the client diagram is the starting point and its accurate to their requirement. Also I would not add more stock it still needed to flip it to do the bottom which is not flat. I actually would have started with it upside down to your config. Then flipping it would have allowed you to grip it with more meat and I would have squared the block first allowing you to tram it more easily. All those thing would make it faster. But I though you did a good job in recovering it. I might have done a do over. Steel is cheap. Time is not.

I would imagine even with my machines and their fast metal removal rates it would take me a solid day to make one of these and some features would have to be simpler, nothing effecting function but skipping some of the aesthetics. This would be a ton of angle plate and rotab work, which doesn't take long to cut but takes a while to setup. Thanks for the plug too. :-)

That came out Orsome John. iam sure Adom will Be very appreciated :) Perfection certainly takes Time Mate.

you guys rock

Can you do a fusion Friday for setting up lathe tools from scratch. I'm doing gang tooling and having a pain figuring it out. For example I have a bin of boring bars. Does fusion require them all to be a certain direction. It seems i can get them to work in any direction but it's a pain to get the orientation right. If you could just go over this whole process that would be great. Thanks

+nyccnc what's that song you have copy written that you play during the actual time lapse?

great job. I usually do the flat or less detailed side first then the Pocket or more detailed side second. as for quoting job shop work, so many factors at play that it is next to impossible to explain. it's a skill that takes years to develop.

You'd have saved a lot of time (and money...by making more parts) if you'd only bought a cnc machine with a tool changer... It's going to to old really fast changing chucks between milling and drilling ops, or just to change out different sized bits. A VFD would be excellent too. Oh and did I see you change spindle speed using belts?

Why not mill what would become the bottom first so that when flipping the part you could have a more accurate reference surface?

that's one sexy chunk of metal!

You have put a lot of time into that part, & it look a million dollars, what did you coat it with, gun blue? If so what brand, ace channel. 👍

Ya can't rush excellence. Sweet. Sounds like some unknowns still in your pricing models. There are some good T&M software packages out there. Not that I recommend a full time T&M approach but good T&M tracking today (even if unused on the current job order) helps zero in on tomorrow's pricing. Until your brain can do it by rote. Then you need a good shop manager who thinks like you. Easy.... NOT.

Yes. Stock is cheap in the grand scheme. Unless you get too much and spend hours trying to machine it off XD You can hold onto practically anything with just .100 (.100 hardened step jaws are perfect for this) so extra 1/8" all around is a perfect amount for stock size. You could get away with less... But why? For part cost? Ya $700-$800 is way high. Maybe half that would be reasonable. Maybe half that

Machining cost: the reason the factory part was cast. But there are benefits to CNC a part like this: an engraver would probably charge $500 to put those logos on there. With the Tormach, that cost you all of $30 of that $700 estimate. Idea: A tool & die maker needs to make an ABOM logo stamp for Adam.

... OH, Adam paid for the shipping... LOL

We all do jobs on occasions without profit in mind but, If you were to do it again as a real paying job it would be far cheaper to do it, as the original, as a casting and just machine the dimensionally important parts. 3D print the pattern as you have already done the Fusion drawing. I don't suppose you will be inundated with requests for K&T parking parts but you never know.:>)

G'day John I don't want to appear to be a smart-arse who's telling you how to suck eggs, I'm instead here to learn from you. However you mentioned machine time, and as your operation gets bigger that's probably going to become something that deserves significant consideration and habit forming on every job. If you could do this whole project again, do you think the order of operations you conducted things was the most efficient way you could have gone about it? Especially in regard machine time? What I'm getting at is, in my humble opinion, the machine appeared to spent a lot of time machining areas that subsequently became air! Just as a specific example, the whole top surface was fly cut, which leaves a great finish but is slow ... and then most of it was immediately machined off!!! The whole right side of the stock was side milled ... and then machined away. Why not just, for example, fly cut only the area that becomes a feature (say by approaching from the left hand side of the stock), and preferably when doing a tool change for a later fly cutting op? I've heard some very wise people say that "the money in machining is made when roughing". They told me that it doesn't matter how you get the waste off, just get it off! That could mean a bandsaw, a plasma cutter, a big-arse roughing mill, it doesn't matter how it's done, just find the quickest way to get that material off! I'd probably add to that advice given to me, not to spend any more time than is absolutely required machining features that will subsequently become air. That is instead just a pile of chips that hasn't been created yet ;) Just a bit of unsolicited food for thought, and it will be interesting to hear and see in the future if there's any value in that line of thinking.

I have seen ppl on cad doing amazing skills on design parts ... I know that you have experience but at the same time you suggested that you don't .... I also understand that you or any shop need to make money BUT ... If I'm just the average guy trying to find someone or a place to help out on cost ... I rather go and take a cad training course and buy a small home base DIY CNC. like "pocket nc" or some other choice I had tried to do this before and everyone I met in reality don't want to deal with a no body like me AND I also have felt unwanted. .. I only watch your channel because I like the to see people's technics like you said "limited material limited budget". I like abom79 because he is realy an old school DIY guy and to me that is more important that a 100k cnc machine that I don't even dream about. I need to try out techshop in San Francisco. don't get me wrong as I don't mean any negative tours you or your channel and thank you for posting your videos.

For fast turn around $600 US would not be far out of line.

$1k for the part is what I estimated based on what you said.

Hmmmm!

But why the pallet?!!

Joke is, if I was doing that part commercially, I'd probably try and talk the user into using 6061 or 7075. I can't see WHY today you'd make it out of steel (except for historical). It is only holding the head when parked. The original was probably a casting, and therefore cheap/easy out of CI, but to make it out of stock? (aka what the motorheads call 'billet' - hate that term), why steel? Never mind that, why that design? Could probably do things like make the ramp flat, or some other shape (do an FEA in the CAD) and optimize the metal removal? Or even, gasp, a bolted/screwed together fabrication

using the Wrong tool or machine can add a Lot of labor hrs to any job... when You Know there are Better choices of how todosomething you should not bill out time because you chose to use an inefficient method.

You guys really need to get a life

Nice!
