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.

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...

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)

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.

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

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?
@ajhartmanaero
@ajhartmanaero 3 года назад
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?
@ajhartmanaero
@ajhartmanaero Год назад
That’s one. Parts cured at elevated temps can also exhibit better properties.

Ive been wondering but for small parts can I just stick my parts in a normal oven?
@ajhartmanaero
@ajhartmanaero 3 года назад
Yes but be very careful of temperatures since a normal oven can get plenty hot to destroy things.

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.
@ajhartmanaero
@ajhartmanaero 3 года назад
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
@pro-touringf-body5179
@pro-touringf-body5179 3 года назад
@@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.
@ajhartmanaero
@ajhartmanaero 3 года назад
@@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.
@mattnsac
@mattnsac 3 года назад
​@@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.

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.
