Rectangular pattern tool when scetching makes this way easier
The high-impact shock testing had me laughing :)
Great work and a BEAUTIFUL product.
Pretty sure I know someone who can do the waffle iron casting...I'll get back to you...
I missed this video from years ago
Your projects are cool mate. Love seeing a new video from you.
Did you post the 360 files anywhere? Or are the files for sale?
(TY, really enjoy your channel)
Is it possible to have a cranny without a nook also? How about the other way?
Let the excess mineral oil drip back into a container and reuse. The oil will come to equilibrium in about 30mins to an hour with most of the excess being recovered just a little will be left on the surface to wipe off
Winston I see in this video of cutting that your suckit dust collector has some additional brackets on the out side of each arm. Is that something you added. And have you done a design of the trivet in carbide create. That I could see.
Jeff
brilliant!
Could you upload the Cad files on your website? Thanks, I think my boyfriend would love these.
When you switch to the 1/8th long reach end mill for your finishing pass, are you doing it by going to the full depth and then taking off a few thousandths all at once, or do you step down the depth as you go? Also upcut, downcut, or compression for this pass?
I still stepped down with the 1/8" because in the corners your radial engagement changes and I was (overly) cautious about the load spike causing deflection. I used an upcut but compression would be even better.
Very cool!
Nice work. Nice go see how this old russian (60ies) invention is still beein used and evolving and even inspiring trivets.
Dare: skydive while holding out 4 of these and land on a ship.
5:56 I can't wait for his model of the Eiffel Tower where he cuts off the top to fit them in the shipping boxes he's been using. :-|
for the modeling, many ways to skin a cat, so yours was fine, but probably would have been faster to do the diamond pattern first with a rectangular pattern in sketch. That way you don't have to draw use two feature patterns or an additional have an additional sketch. Also a professional would have probably just used one or two sketches for the entire model.
I think making sure they fit in a convenient shipping envelope was a great idea! It would have been such a Doh! moment if you were *just* 10 mm or something off ;-)
New viewer, and I am SO glad I found your channel. Getting a shapeoko 3 Xxl in January, your videos have been getting me excited!
There is such a thing as Teflon coating on a hard coat anodize for aluminum. We just had that process done on some parts at work
Yea, I did come across that process in my search. Just wasn't sure about who to go to for the teflon coating, since it's not as common as anodizing.
Winston Moy might be able to give you contact details for someone who does both if you are still interested
If you think they might be willing to take on small batches, shoot me a message. Not sure if I'll go down that route, but it's good info to have.
Nordicware in MN does Teflon coating on aluminum.
That was cool! I loved the project. Keep it up bud.
Best Matt
That is super Nerdy!!!
You should make a full set you can assemble for the entire rocket! Sugar, tea and coffee jars for the stem. Cookies in the payload. Eggcup Merlin's!
On the waffle iron. If you could mill down 2 cast iron pans you should be able to do it. You just would have to make a mechanism to press the 2 pieces together.
Very cool.
I can suggest something to help with Fusion 360.
Learn parametric drawing. Not to be critical, but your CAD skills are kinda lacking (I mean that in a friendly, supportive way :) )
With a simple model like this, you should make the entire thing from a single base drawing, and extruded all at once. That way when you make edits, the entire model will update properly. Just go back and edit the original drawing as needed. When you click "finish drawing," the timeline will advance and the model will update. The coves most likely will have to be drawn on angled planes after the model is extruded. The method you used should only be used in the most dire need - it is a huge resource hog and can cause other major issues with orphaned bodies.
On the machining end, stop mucking around with interpolation and avoiding tool changes. Nothing beats a drill for removing stock - drills are really fast and cheap. I bet drilling 4 small holes in each corner, then following up with a big drill in the center will still take 1/2 to 2/3 the time of interpolating. Even just plunging straight down with a big center cutting 2-flute endmill will be better (plunging is almost always faster, uses less HP, and overcomes lack of rigidity). Then just go right in with a finish mill. Get a cove tool to make the scallops.
Interpolating is sexy, but a huge waste of time for most jobs.
Thank you, sounds like very good advice!
Sweet job Winston! (Who needs RUclips money!)
You know the Mrs. is the director of Product Development for the largest Tabletop Company in America, and is in China 5+ times a year visiting all the factories (Ceramic, pot and pans, flatware, glassware, etc).....maybe we should talk....I do like Waffles!
Hah. Not sure if the demand would warrant going to Shenzen, but it's worth a look maybe lol. I'm thinking cast iron stovetop/oven application, since anything with a heating element really jacks up the complexity...
I'll ask her to look into it.
Do you have a g code file for this.
Love the amount of work you put into this and awesome project btw 😉
Hey man great video. Awesome shout out to Master Howarth. New sub here.
You could’ve made the scalloping process easier by using a cross-hash (same spacing as your ribs, just offset half the distance) of cylindrical shapes and remove from that.
For the cutouts try tabs, onion skin, or pocket the space instead of doing an inside profile cut. Any
You have the blanks for sand casting already. Just need a furnace and some sand
Little more complicated than that. Waffles need a draft angle/taper on their walls so that they'll release properly.
I have some experience with CNC-machining, but I have only used real CNC-machines like the DMG DMU50. I'm looking at the possibilities of these machines and this video got me thinking. How do you make the rounded shapes in the Z-direction in the second version of the product? can these machines cut 3D simultaneously?
Yep, they're full 3D machines. Parallel finishing toolpath in Fusion 360.
That’s very good to know. I was worried it could only be used for 2,5D milling. Thanks mate!
you can make silicone copy mold, then wax and lost wax casting aluminum. but surface finish on casted alluminum will be a lot harder
Surface finish on sand castings is questionable, but if you do a plaster mold it's pretty good. My biggest question right now is how to anodize a cast piece, because as impurities precipitate out, you'll compromise the finish.
i would first try tumbling then electropolishing
👍🏼 Yea, that or bead blasting was my thought.
Good idea with the plastic bag.
Long reach 1/8th endmill aka deflect-o-rama
You can use woodprix to build it in the cheapest way.
You really deserve a spot at SpaceX
I've been there a bunch of times, and know the inside secrets, he deserves a lot BETTER than SpaceX
The only problem is that if I got a job at SpaceX, I'd probably have no time for making videos...
You'd have time for 3 things. (1) A 12-14 hour workday, (2) an UGLY commute and (3) Five hours of sleep.....and that's a sad fact. And I love SpaceX
are you trying to make a big model of spacex falcon
Haha, I wish. It would be fun to rotocast a rocket, but my current ambitions are actually to machine a Dragon capsule... 🤐
it would be cool to make a working rocket model of falcon maybe getting it to land just like it might be able to use arduino to control everything
для чего она нужна ?
This was a cool project which inspired me to create a similar one in Open-SCAD for not only CNC (as you can output a 2d svg), but a laser cutter, vinyl cutter and yes even a 3D printer! So you can see the video here: ruclips.net/video/rTexVrDBWVs/видео.html with links in the description to download the code. Also created a Customizer on Thingiverse for those not wanting to mess with the code which can found here: www.thingiverse.com/thing:2654834 that will export both STL and SVG file. Winston, keep up the cool projects and would love to see you do a video touring Space-X with Elon (I'am sure they have a few "used" gridfins around to let you take home)!
there are foundrys around that can take your pattern and cast it in iron.. so you will have to make up a split pattern so they can make up the sand filled casting boxes . you will have to design in a half ball so you can lift and pivot to flip sides.. look at Grizwold waffle irons for that shape.. and for the base shape idea. you can get spring handles to cast in thru Century spring company.. www.centuryspring.com/stove-handles.html
This should be a special edition Tesla feature for aesthetics
Are you selling these?
I did a limited run for Etsy and put the project on the backburner. May revisit in the future if I can make production more efficient, but for the moment I'm not making any more.
@@WinstonMakes Please do!
they probably do the real fins with a CNC
Can you make me one?
wooden gridfins?? is that for your vegan falcon 9?
A landing leg kabob stick
It's also Soyus style, Soviet military style etc. F9 isn't where it was introduced :)
Cutting bord
I don't understand why spending time making those useless parts ? A "sophisticated" pad for hot dishes ?
