As far as the electrical side there are some great YT tutorials on wiring a PID to control your oven...that's what I used when I built my powder coat oven.
Aj I see you have two vac pumps connected to one another. Is this simply to add more pull power? Wonderful tutorial, I love how simple your heater solution is, been watching a lot of videos of people doing all sorts of creative electrical and oven things, yours is just simple and straight forward haha.
Looks good. Gives me some motivation to start on my pre-preg oven. I'd be curious to see the temperature delta between the interior and exterior panels after several hours of running.
I have a question about about curing carbon fiber... do you NEED to heat cure it? I've seen people talk about making carbon fiber panels, but this is the first time I've seen people talk about using an oven, but to be honest, the stated reason doesn't seem to apply to my proposed use case, as i don't really care about are bubbles and whatnot... all i need it to do is be able to do a heat bend at one end after it's cured, and i don't so much care if it's vacuum bagged or even heat cured, as it only needs to lay somewhat flat for use as a screw-on side panel for a small bicycle baby trailer, and all i care about is making a flat panel that's approximately 2ft x 2-3ft fir each side, and a longer one for the back, that would then get bent on the top end... Also, another question, is it possible to take already made panels, and connect them together, especially top/rear panels that have a curve, being connected to 2 matching side panels that will eventually just slide over said trailer frame and attach with a couple of screws or already existing frame bolts? Basically, the whole thing put together would replace the original canvas top enclosure, and I'll eventually make it weather resistant...
Hi, I've seen in your other videos that you have huge cutting table. Wanted to ask you what kind of surface material did you use to be able to cut with pizza cutter and not have the surface ruined? I guess anything else would be damaged by it and sliding fabric over the cuts would pull some fibers and make distorsions. Thanks
I feel 2 heaters on the sides, with the fans heat more evenly, and are like $15. Plus one super hot heater can be an issue with proximity to molds sometimes. But I’m sure it could work. And I’m sure some of my terminology isn’t exactly correct so apologize for that. The oven gets to temp in about 30-40 min so plenty good for me
@@ajhartmanaero no problem, I'm amazed you can get around 130* that way, I used a $69 base board heater, 1500W on 240V it only uses 6.2 amps, remember this is how you can reduce the load on you electric panel since you are already running short of breakers.
@@pro-touringf-body5179 never thought of a baseboard heater but would be an issue I feel with my large flat mold or when I have to lean hoods against the back wall. Didn’t know they had such a low draw tho which is nice. And I can easily open up 5 slots on the breaker and I think 2 are still open. So still have plenty of room and the whole shop is just about wired.
@@ajhartmanaero whenever you double the voltage, you halve the current so a 20A load at 110v will be 10A at 220v. Its the same amount of power used (or within a few percent as there are some other things that play into it) its just lower current so you can either run smaller wire or run more current for the same size wire as a 110 circuit.
An oven made out of wood ???? I'm an industrial designer. That might be cheap but it's extremely dangerous. Pay extra for sheet metal and a welder fabricator and DO IT RIGHT. If you have the funds you can also buy a giant home propane tank or a giant delivery tank from an 18 wheeler and turn it into an actual autoclave (with vacuum pressure)
You are a skilled composites tech and have great creative talent but my favorite thing about you is, you are a real dude- no BS.
honestly this whole set up is so big brain
Love this: simple, cheap and effective.

I'd like to watch you build a wing with the vacuum method.
Awesome info! Thanks for sharing with all of us.
Great work.
Man I've been wanting to do that for years

In case one dies I can just turn the other on.
Great videos, thank you. Can you recommend an online retailer/wholesaler for carbon fiber cloth?
Fiberglast in the US
Thanks for this video. Huge help 🧤🧤🧤
Looks good.
Gives me some motivation to start on my pre-preg oven.

I mention it in the video, but an oven like this would not work for prepreg temps.
@@ajhartmanaero well aware. Mine will be steel frame with fire brick insulation and fire suppression built in.
Totally different
@@richm7936
Yeah, I thought this oven was for prepreg. Have you found any ‘tubes on DIY prepreg ovens!

Awesome video. Are you doing this because you reside in a cold climate, or is there a benefit to curing in elevated temps?
Multiple benefits to it.
Very good video !
Thanks for the info!
looking forward to future updates. Let us know when you are up and running again.
Already there. Videos are a week or 2 behind real time.

Just a cutting mat.
Halo bro, please make vidio tutorial blade longfins carbon or fiberglas on vacum proces ❤
Good video bud. I take it your under bench oven was built the same ??
Pretty close.
at what temp the oven works?
Any need for a "bathroom fan" to vent fumes outside while/after drying, instead of just opening door, venting into the rest of your shop?
All closed mold stuff so fumes are not an issue.
So pretty much the main reason someone should use a cure oven is just to speed up the process?
That’s one. Parts cured at elevated temps can also exhibit better properties.
What heat cycle do you use for your parts?
The “just add heat” heat cycle.
Ive been wondering but for small parts can I just stick my parts in a normal oven?
Yes but be very careful of temperatures since a normal oven can get plenty hot to destroy things.
Can i ask the main difference for not post curing and using the oven ?
Material properties.
you use pre-peg fiber in the oven
No
why on earth would you not put heaters on 220 v and use half the power? FYI those two double breakers you say are not needed are 220V.
I feel 2 heaters on the sides, with the fans heat more evenly, and are like $15. Plus one super hot heater can be an issue with proximity to molds sometimes. But I’m sure it could work.

No
are you going to build Airplanes ? oven is far too big.
No. Size is fine. I just finished my small oven today.
Awesome video. I do carbonfiber overlay. Use West System epoxy. Should I build a Box with electric heaters to help them Cure?
@karbon_workz
It will cure faster but not a necessity for what you’re doing.
