- In this episode of Making Things with Milo, Milo takes on vacuum forming an RC car body which presents an interesting challenge. Due to the undercuts present in the shape of the car body, a traditional rigid tool can't be used. Rather than redesigning the car body, Milo makes a flexible silicone mold that sits atop a rigid support structure.

I’ve been an RC enthusiast since 83 and had no idea how much work went into a lexan body. I’m a fan of DIY projects but don’t think I could pull that off. Well done
That's about when I started racing 12th scale RC cars too. MRP and Parma made the best detailed lexan bodies in the day.
Genius idea for vacuum forming hard geometries... thank you so much for sharing!
Glad you liked it!
you work is extremely detailed you know your skills thats for sure. especially with that vacuum pressure work raising & dropping that mix & also that 2nd bucket mixing stage with an even bigger mixer, you are very thorough with your work.👍I tip my hat to you Sir.
Nice work. I've been making V-Formed Polycarbonate bodies this way since 2019. I use the 60 duro hi-temp material and the aluminum-filled epoxy for the mandrel. Much better method for getting precise detail than a hard tool with little or no worry about undercuts, back drafts or difficulty removing parts from the male mold. Thanks for sharing.
Genius move! Thanks for sharing this!
This was a thorough and detailed demonstration of vacuum forming. Thanks
Having just completed a new 24x24 vacuum former, this was an incredibly timely video. Thx!

Absolutely brilliant video Milo ! ; ) ...................... right up my alley so to speak. Watched it 3 times already!
Vacuum forming and designing tooling plugs is what I do, been using very very expensive Vac-Cast epoxy resins with Aluminium powders in it for years, closest thing to real manufacturing tooling plugs ( or Bucks ) that the industry use. Negative draft angles have always been a major issue ................... until now!
Very cleaver use of the 'Skin' over a solid form. A technique I'm sure I will now be using myself. I had no idea, nor did it occur to me that you could vacuum form over a silicon rubber. As I design prototype automotive headlights the methods you've just shown us, is sure to make my tasks so much easier, not to mention, the possibilities of vacuum forming shapes that otherwise wouldn't be possible.
It was also very interesting to see you actually preparing the 'Free Form Air HT' @ 16:28, I tried one of your other products 'Free Form Sculpt' as demonstrated by Janessa in the following video
th-cam.com/video/wja4FNQ4Ojg/w-d-xo.html&lc
The product was awful ! ................ I found it to be unworkable, my comments at the time were somewhat harsh, my frustration was very clear at the time. But 'Free Form Air HT' seems to be the product for me. We shall see ; )
My vacuum forming machine happens to be the Formech 508DT that you used for the demonstration, great machines. I also have a 20 Litre degassing system from 'Easy-Composites' in the UK, so all I need now are the materials ................... hopefully I can buy them through my regular Smooth-On supplier in Europe.
Many thanks for these great tutorial videos guys, keep 'em coming ; )

Literally just blew my mind! I was wondering how the hell you were going to work around those draft angles! Best customer service in the business too!!!
Check out this latest episode of Making Things With Milo!
Thanks Milo and Smooth-On!
Thanks for watching!
Thank you for this video! I have been trying to explain this process for making a vacuum forming buck like that to the people at the makerspace, but my description always fails to describe just how much detail and saved time this process produces.
Also, I did not remember hearing you mention this, but you should file down the edges of the cutting tubes (either inside or outside) so that the act like a blade and punch through the material more easily. File down the inside if you want to keep the outside dimension accurate and vice versa for the in side dimensions.
Great idea! Thanks for watching, and don't forget to subscribe!
Great job. Congratulations !
Fantastic content. I didn't even know this technique for undercut vacuum forming with silicone skin over a rigid center existed. Very cool.

I ve been forming bodies for more than 10 years and i'm always happy to learn new skills! The solid core with rubber skin is a brilliant idea. Most of my molds are in pu resin charged or not. I use silicon for fiberglass molds but never thought of forming with it. Thanks again, will try this ( on my formech 😉)
I’ve been incredibly curious as to how people make these bodies. I really want an 02 WRX 1/10 scale body. Is this something you can create?
@@slicelifetv vacforming technique is made to build in series, so I can make one body, but customer need to pay for mold, so for one body it's rather pricey 😉
Very satisfying result and a useful technique.
Many thanks
One year on but, great information. Thank you. 😁
What a wonderful process! But so labour intensive!
Thanks for watching!
I think there is a way for getting better detail in the body. That is making an inverse mold, so the external parts of the body goes against the mold walls. I mean, a concave mold. That way you'll have the best body detail outside and not inside. Tell me what you think of this. Regards and congratulations for your amazing work.
So cool!!
LOVE THIS!!!

Really learnt a lot, thank you.👍🇬🇧
Your welcome. Thanks for watching.
In the late 1980s, I had a few of that specific RC car from Radio Shack, the Audi Quattro. I still have them. I also have the service manual with the electronic schematics, mechanical assembly drawings, etc. I really enjoyed this video showing the entire process of reproducing the main body. The original car was painted metallic silver and covered with paper decals so I assume the one in the video was stripped and prepped prior to the video. The original car window piece is black plastic so I thought it interesting to consider the possibility of using similar procedure to make a new clear polycarb window part for the original car body to expose the interior if anyone wished to model a new interior and driver figure.

GRRREATINGS from Cologne Germany! ❤️❤️💥
Thank you for watching!
Is that a time machine to the left in the workshop? It has a flux capacitor! :D
I took my time to watch the vacuum mole making processes and my interest is built strong to lean and study the right material needed to be used for plastic doors production for houses, I will really appreciate if I am educated on how to go about it. Mostly likely on video clip. Thanks

What is the thickness of the thermoplastic used, Also are there thickness options on a particular website?
Gracias gran video

Tha Flux Capacitor at 33:24 is getting ready.....wonder when it is going to
Great video.
Glad you enjoyed it
Your braver than me mixing that bucket of silicone without holding on to it I keep waiting for the bucket to helicopter and spray pink everywhere in sight trust me I’m not as lucky as you just thinking about not holding on would cause it to go everywhere and that’s before I start mixing 😅
Great video milo!!👍
Glad you liked it!
How amazing guys, Great job!! would you mind telling me what clear plastic that is that your using & where can I find sheets of clear like that? Thank you
These are styrene sheets for vaccum forming.
Nice FLUX CaPacitor in Upper Right Corner lol
Where can I buy everything to make these bodies at home?
Give one of your local distributors a call - www.smooth-on.com/distributors/
What vacuum pump are you using in this video? Thank you and have a most awesome day!
This is a Formech Vacuum Former - www.formech.com
@@smoothon Sorry I did not articulate, what make and model vacuum pump are you using to de-gas the silicon compound?
This is an 8 CFM vacuum vane pump. Many different types are available from online retailers.
Great video! Is that a flux capacitor in the background to the left?
It is!
Very very cool !
I just made a rc body out of fiberglass.
Do you think it tolerates heat for vacuum forming?
It would depend on the resin. We recommend you contact the resin manufacturer for heat tolerance.
I used fiberglass to make my bucks for custom rc bodies when vacuum forming
@@smoothon thank you.
very good job!!!

Nice video and very detailed. Do you make molds for customers? Thanks
Thanks for watching carter cartier. We do not provide moldmaking services, but we do have a list of moldmakers on our website: www.smooth-on.com/moldmaker/
@@smoothon thank you for the info.
i plan to buy this silicone rubber..plan to casting small head sculpt..can i have the information about the srinking percentage? and how long it will stand the mold when casting pu resin?

So how much do all those chemicals cost? Looking into vacuum forming for exactly the reason of 1/10 RC shells, but that looks like several hundred minimum?

Nice, very nice.
Is there any possibility to order this Audi Ur-Quattro Shell? Cause I am a huge Audi and Rallye fan!
Quick question if I may ...............
I had an issue using the release agent 205 ( both silicone molds stuck together slightly in places ), is it possible
to use 'Sonite Wax' as the silicone to silicone mold release?
TURK
Some customers use petroleum jelly as a separator for silicone to silicone as well, but it is important to apply a very thin layer.
I use the aerosol version of this, the 200 mold release and i have to spray the crap out of my mold, i mean shiny, just before the point of puddling up. Also make sure your silicone is properly cured (not just set but final heat cure too) or else this release agent won't work. Honestly just use petroleum jelly, it never fails. Also talcom powder works ok but I've had it fail occasionally.
hah! So I can save my not used RC bodies :D like pro10, WGT (pan car 200mm), 1/12 and 1/10 IC ;)
master
Thank you.
Is that a flux capacitor in the machine behind you?
It's a non functional replica. 😊
hello excellent work I want to ask what kin of plastic are you using for those bodysuits or what are they called and what is the thickness?
This is styrene plastic sheeting.
Ok
Thanks for this. This is so much better than the old school way of form RC bodies. Any chance i can buy a few of that body?
Thanks for watching Daohaus. We do not provide these for sale.
So what can we do if we have the lexan body and want to make a puck because all the detail is on the inside of the lexan body
Hi there! This is a good question for our tech support team, can you send them a ticket here? www.smooth-on.com/support/ticket/add/agree/ Thanks for watching!
How would you make a 1/5 scale rc car body from a car that hasn't have a rc car body ? I would like a 1/5 scale vw jetta mk4 and i don't know where to start from scratch because i don't have a body to make a form with

I have no idea what you were doing. But when a see a early Audi like that I have to stop and watch
Thanks for watching! 😃
I will never complain at the prices of RC bodies again!
👏👏👏👏👏👏👏👍
Love the UR Quattro body. Would you sell one? Also would you ever consider making a B5 RS4 Avant body?
We do not sell RC car bodies.
At first i thought it was a mid 80s dodge charger.
I can't get hold of 'FreeForm Air HT' in France, and my regular supplier in Holland doesn't stock it.
Can I use regular 'FreeForm Air' ?
TURK
T4 Concepts
Regular Free Form AIR may deform under the heat of vacuum forming.
@@smoothon Thanks for getting back to me ................ I could of ordered it via my regular supplier in Amsterdam but they said it would take about a month to get here.
So I ordered the 'regular' FreeForm Air for the time being, I'm hoping I can at least run one vacuum formed part ( maybe 2 ) just to check my prototype.
I intend in making a 'manufacturing' tooling plug from my FreeForm Air if my prototype turns out OK.
TURK
Would you ever re-produce an existing lexan body for someone? I have a 30+ year old body that I would like to reproduce. There are no special undercut features or really detailed parts. I have been looking for years and cannot even find a reference that this body ever existed.
We do not make molds, but have a list of moldmakers who may be able to help you: www.smooth-on.com/moldmaker/
How would I make a full size car hood? You have made many many large molds but I need to make a custom car hood. How can I if you would make one that would be great?

11:04 on the left we see a flux compensator
Looks like someone has a keen eye for spotting time-traveling equipment! Good catch!
can you make or tell me where I can get 1/16th scale bodies?
Thanks for watching but I'm sorry I can't help you out there.
What kind of Plastic is this?
The sheet plastic is styrene.
Ford gt 40. 1/8 scale
If I were to go to college to learn how to do this, what would I study?
Many engineering programs have moldmaking and casting as part of their curriculum.
Are you able to create the mould for me from a 3D print? What you charge to do it? Please contact me as soon as you see this.
