I decided to refine my process for producing baby crew dragons, so I could churn out models on my PocketNC as quickly and reliably as possible. I also added some finishing touches to the capsules using a 3D printed fixture.
The model I used was made by Thingiverse user Zastro.

You could warm up your dragons so they expand a bit to get the magnets in.
11:39 That transition was 800 grit level smooth
have you ever used sandpaper that has 0.3 microns grit?
i tell you, it leaves a perfect polish on steel
If you’re going to mill the bottom anyway, you could just start the bottom cutoff to indicate position, and finish it with a hacksaw. Perfectly legit.
Check out loctite retaining compound. Not thread lock, but retaining compound. Tolerant of .001-.003" slip fits, and it would be the perfect thing for the magnet in this case. It is designed for permanent attachment on cylindrical fits. I also like press fit and sometimes a shrink fit by heating the female part first, but retaining compound works so amazingly well and can be removed with moderate heat if needed that it's my go-to about 90% of the time these days. Hope you'll check it out.
Absolutely awesome that you let us in on those very professional "make it perfect" thoughts and tricks!
the one with the magnet could levitate and be a cool floating gizmo
Really enjoyed this! Your breakdown of optimizing the machining to cut down the time was great. 😊 We keep talking about getting one of these Pocket NC mills. They just look so fun!
It's probably the best way to learn the fundamentals of 5-axis and prototype small parts if you're not ready to drop 5-figures on a big machine. Wouldn't do production work on it, unless it was plastic or very small aluminum parts just due to speed, but it's still handy to have around.
Pretty cool! Spacecraft models and satisfying machining footage, you've got my subscription.
12:35 "nonsense" fits very well xD
I didnt even know this was tool existed!!!
Dealing with heat from cutting aluminum is something I've dealt with a lot before. Take bigger cuts, cut faster, and use an air blast. If you're generating heat, your doing so because of friction. Nice work!
if you could create grooves to slot fins into, you could get stock closer to end size and machining time would be cut down by at least 80%. but you'd need a separate function that creates fins, and then you glue or friction fit them in. the overall time savings would be huge. less than an hour per.
Have you ever used a dead blow? IMO, they're more efficient at energy transfer than a rubber mallet, as the mallet likes to "rebound" after it strikes.
I know the Dragon doesn't use a fairing but making one for it anyway would make for really classy on brand reusable packaging. Oh and fill it with black foam with a little spritz of white paint to make a starfield. Or run fiberoptics through the foam and have it light up the stars when you open it.
The fairing packaging a cool idea. Would be quite fitting for an X-37 model, since it does launch in a fairing...
@@WinstonMakes How about painting the box to look like the Vehicle Assembly Building.
I like the idea but it doesn't scale up. Painting is a time intensive process. Ink transfer process might work better, or use a vinyl cutter as a stencil.
3:38 Was the tape used to prevent chips from getting into the machine?
Not into the machine, but into threaded holes used for mounting workholding/accessories. I'm a little OCD about vacuuming them out every time I check on the machine, so I decided to bypass that problem completely by covering them all up.
@@WinstonMakes Can't you make something to thread into it and close it off?
@@AntiViGames May be screws.
polycarb mix filaments may handle the heat also look into this stuff from loctite 680
Awesome Job!
When I will make a 5 axis mill I will try it too!
beautiful work! im a little confused as to why the pocket nc is so expensive.
Good stuff, thanks for the chuckle...PLA...yeah......HOT.
Beautiful as always Winston, thank you.
Great video. Awesome fabrication. Beautiful capsules. Mahalo for sharing! : )
I would make this hallow and screw together, top cone part onto the cylinder body with the fins. you could probably cast these too.
Nice work Winston. Quality video. Adds are annoying but congrats on the sponsor!
Just wondering if you had thought of doing milk turning? Rotate the B axis while slowly ramping in on Z to take off the bulk of the material. Would probably work for the top side and the underside to potentially save even more time? However, I’m not sure if the machine can handle it either? Something to look at, if you haven’t already.
Great stuff as always! :)
Pro tip for setting your stock stickout:
Follow this guide and enable manual passthrough in the post processor:
knowledge.autodesk.com/support/autodesk-hsm/learn-explore/caas/sfdcarticles/sfdcarticles/How-to-use-Manual-NC-options-to-manually-add-code-with-Fusion-360-HSM-CAM.html
Make a Manual NC operation, change the type to passthrough, and put this code in the box. Change T6 M6, and H6 to the tool you plan to use. Inspect the point end point of the stock in fusion, and take that absolute y value and use that as your Z value on the line that containes g43.
T6 M6
G53 G0 z0
G53 G0 X2.5 Y2.5
A90. B0.
M0
(Z stickout)
G0 X0 Y0.125
m0
G43 Z2.545 H6 F20
M0
G53 G0 Z0
G53 G0 X2.5 Y2.5
A00. B0.
run this operation at the begining of the setup, make sure your stock is not sticking out too far so it wont crash the tool, also you may need to add about 0.020in to the z stickout value depending on how much takeup your collet has.
The manual passthrough is extremely useful since you can write in manual code, and not have to add it in manually after each time you post it, and its saved in fusion.
manual passthrough is possible on any fusion post. for you router it would be useful as a pin stop, to but the edge of stock up to.
interesting work!
I thought by law you were only allowed to make turbo impellers with this machine : )...very nice work!
You are a genius sir!
Hopefully the creator of the stl files is o.k with you selling these.
The model is released under a creative commons license. As long as he attributes the creator (which he did in the description) he should be fine.
I would totally buy this
Solid slugs for shotgun nice 👍
Could you have used bar stock that had a small dynamiter, to have achieved a similar result in material reduction? Also could machine an Aluminum fixture to hold the capsule for other machining and eliminate the worry of the plastic one melting?
What is the music called in the background? Found nothing in the description.
Thanks!!
You should make pen housings shaped like dragon 2 and crew dragon as pen caps then sell them as collectibles.
Can it use stainless still?
What a price?
So cool!
I recently saw on NYC-CNC John using hot glue for holding parts when cutting off tabs, do you think a similar method would work at 6:30 when you hold the dragon capsule with your finger, by filling the apposing side with a blob of hot glue to keep the capsule steady (without need for your fingers) :-)
I'm going to try that next time. Thanks for the suggestion.
Do you think the NC could do titanium?
is the model published under a commercial license other wise selling them might get you in trouble
CC 4.0, commercial allowed.
A larger issue would be any implicit trademark on the design of the capsule by SpaceX, and they've been known internally to not be very tolerant of that sort of thing.
@@troy4393 Surely not? Provisional multi-billion tech and they don't want it copied? Churlish much. ;)
Omfg you have to send some of these to Taofledermaus. These would be perfect to test at Mach speeds!
Nice video. I hope you have the license to produce this model in series!
Wow Winston, I love these! You could even make a launcher with an electro magnet that creates an opposing field when you push a button ;) Or, if you send me one, I will make a launcher that's 3D-printable and create an instructable on it (and make it all open source).
Need to send these to that guy who shoots all the different shotgun rounds
Taoefladermous!
What CAM software are you using?
Nice work:-)
Can you replace the drills in a pocket NC. I want to use a diamond drill bit
You can install any bit that you can fit into a standard ER-11 collet, but you should also consider whether or not it's a good fit for the machine. Some diamond/grinding bits for a Dremel may not work well at the lower speeds of a PocketNC V2-10. And abrasive dust from materials can damage the machine.
are you selling these? If so where?
These machines capable of full simultaneous or just positional?
Full simultaneous 5. But can't target the facets of an STL file to use those more advanced toolpaths like Flow in Fusion.
@@WinstonMakes didn't even know you could cam from an stl.
@@WinstonMakes would love to see a follow up video, where you model it yourself and then do full 5 axis mashining
dude is that a mini 5 axis mill?!!?
you know things get real when you bust out wolfram uhuh
Why not make a brass coin with your logo that is impeded into the bottom similarly to how you did the magnets.
So you took a file from thingy now your machining it and plan to sell it ?
Pretty much.
um holy shit where do i get a tiny mill like that????????
Wow, this is amazing and I want one, just subscribed. I’d pay $50 for one with a magnet
Honestly $50 is a bit low for something like this. 3+ hours of machine time and more than an hour of active time, plus the cost of the stock.
So are we able to buy one?
Not yet.
Can u do a video talking about different types of cuts cause rn that sounds like foreign language lol
Cast it instead
Cool Roket. Are you interested in trying 3D printer by the way? Maybe we can cooperate on it?
I will EAT SOMEONE to get one of these..... SOO neat!
Just got lost on The Ethernet... Again
It evades me why people on small weak machines use adaptive (trochoidal, dynamic etc etc) and claim they want higher efficiency.... it's actually quite sad
Huh
Tesla bullets
Eco friendly
And noise free
Kill people 7 times faster
