dude if u dont spray the kawool with rigizer u going make your self sick and i mean bad. Because if you dont use rigizer you will inheal the fibers that being burnt and mess up your lungs trust me i seen it first hand what that stuff can do to a mans lung

[@RedBeardOps]

@@AndrewMurphy8383 Yeah when building my forges I coat it with satanite to seal in the fibers. I figured since the conditions of a toaster oven are very static (no major air flow from a blower or material contact with the insawool) that there wouldn't be a significant amount of harmful fibers thrown up into the air. Could be wrong. A better solution would be to use some jacket insulation like those used to wrap water heaters.

Man this video really helped me to understand the wiring for a PID system. I bought all the components over a year ago to do this exact upgrade to my oven, but was a little intimidated on the exact wiring. Thank you for giving us such a simple and exact tutorial! I'm gonna give it a try this week.

Good luck David! I don't think this would run a heat treat oven with 230v? Works great for a little tempering oven though!

[@davidscadlock5569]

@@RedBeardOps I got my PID control system setup basically following this video & wiring diagram (with minor variations). Bought 95% of the components from your Amazon links. Got the Inkbird PID. The oven I bought is 115V so all the components worked just fine. I got up to 1500F on my first trial. I saw in your recent DL/Knife build challenge video that you had opened the control panel to cool the SSR. My SSR got very hot in the sealed box. I'm looking into a small 115V fan that I can mount to the panel to keep things cooler. I will try just using "P" control & see how it works. I can send photos of my setup if you are interested. Thanks for all the info you share. David Scadlock

[@MrSoloun]

Good vid, very helpful. I like the ide of having the control away from the oven.

[@RedBeardOps]

Thank you! Yeah, I agree. I think it's possible to set it up in the side pannel, but you need to be on point with your insulation. I like having it outside of the toaster A.) for the heat but also B.) for the ability to use it with another toaster easily if this one dies. Thanks for watching!

[@TheJokerMachine1]

Great instructions. I made the same in a $10 Sheffield plastic ammo box. I added a 12vdc miniature fan in it fed off a 9vdc adapter. A little quieter than using a 12. Wasn't sure if the SSR was gonna get really hot. I put a 2 amp fuse in mine since I'm only using it for a small heater coil, not an oven. I tried hundreds of settings on the Inkbirg and finally lucked out and have the thing with only a 2volt swing using PID numbers. Your right about auto tune. Kept occilating. Still can't believe I got those PID numbers.

[@IronSparks155]

Looks good mate. As a sparky I would recommend that you insulate the self tapping screws, wire the fuse before the switch (to protect the switch) and if it were an option, get a smaller switch and mount it on the front where the fuse is for convenience.

THANK YOU!! I really like this second video! Will this get the oven to 500 degrees? I need to temper most of what I'm making at 460 or above! The oven I have says it will go to 450 but in reality, I can't get it any higher than 400 and that just won't give me what I need. I have extra Kaowool and does it need to go inside the the box of the oven? Again thanks for the instructional video! You did a great job explaining everything!!!

[@RedBeardOps]

Hey Kim, glad you found the second video. I think it would be possible to get this oven to 500 with the appropriate insulation, but I haven't tried it. I recently lined the door with adhesive aluminum heat shield and it greatly increased the oven's performance. 500F is pretty hot!

@@Anderson-HandForged You can if you adjust the wiring in the toaster so that the knobs are bypassed. You can also turn the knobs to max and it should work the same.

[@RedBeardOps]

So on the oven itself you should set it to Bake and max temp. In my case I hard wired past the knobs.

[@disturbedsilence76]

are all PID controllers wired the same way? I am playing with an inexpensive Rex c-100. I am just wondering if the wires connect in the same # spots. Thanks for the video!

I think they all are from the save vendor. All the Rexc100s will be the same I think. If you get an inkbird or my pin it will be different. You'll have to look at the manual in that case

Man, I really don't know to be honest. The SSR is 40amps so I think it would work.

[@goodwoodenmonkey]

Hello! Thank you so much for the great video! One thing that wasn’t clear to me is: do you just plug the toaster oven straight in to the PID control box? Do you need to rewire the toaster to bypass the built in temperature controls? Or just turn it to always on and set the built in temp control all the way up? Thanks again!

[@RedBeardOps]

You can do it either way... be careful if you re-wire the toaster... this is what I did, but you could just turn it to full blast. The box will control power to the toaster to hit the temp.

[@brandonkilbury9264]

Hey man, Im trying to make an oven for curing composites and your video seemed a great place to start. I got the inkbird pid controller kit from Amazon and I've got it rigged up to a toaster oven but I'm struggling with really bad overshoot (say 275F for a set point of 200F) and I've tried a ton of different PID settings but nothing seems to have a significant effect. Even with P=1 (minimum), I=1 (minimum allowed by the inkbird) and D=9999 (max allowed) it still overshoots like crazy. Any recommendations? Thanks!

[@RedBeardOps]

Hey Brandon, my recommendation is to only control your PID on P (proportional). (I to 0 and D to 0) Then run some 10-30 min test to see how it performs

[@chadcarpenterred]

Does that controller hold its last settings once powered off, or do you have to re-calibrate, set temp every time?

[@RedBeardOps]

Hey Chad, it holds its previous set points

[@leetpg]

I just build a box following your guide. I used an Inkbird controller. It seems to work great however the temperature reading is very slow. Do you fire up your oven, let it get to temp and stabilise a little then throw in your blades? Just as an example(I'll use Celcius), my multimeter probe reads 50 degrees C while my in oven probe is still at around 30. By the time my multimeter is at 200c, my oven temp probe is around 150. When I read 200c on the oven temp, the multimeter is nearly 240c. Its slow and feels bouncy. Any ideas?

[@RedBeardOps]

Man, that does seem bouncy. I think you many need to do some "test runs" with a stop watch and graph the results to see what it's doing with different set points. Easiest way is to get it close with your "P" set point alone. Each oven will react a little different since they're insulated different and are different sizes. Depending on your controller you can try the auto tune as well.

[@davidaustin6657]

What insulation are you using inside your oven? I was thinking about using ROXUL (stone wool insulation) in mine.

[@RedBeardOps]

Hey David, I'm using Kao-wool insulation that was left over from my forge. You can get it here - amzn.to/2t07c7v

[@JackOfAllTrades2022]

I’m going to build one of these for my electric smoker. Only I’ll use a toggle switch and put it in front with the fuse. I’ll build the box out of metal since I’m a welder and have the steel.

[@RedBeardOps]

Nice! Good luck with your build!

[@Anderson-HandForged]

question instead of a light switch can you use a on/off toggle? i was gonna start making this today i dont have a light switch but do have extra toggles your videos are awesome im also in the process of building my heat treat oven just waiting on elements and pid when are you gonna make your own?? thanks again bro much appreciated

[@RedBeardOps]

Thanks man, Yeah I think you should be able to do that no problem as long as it's rated high enough. I'm not an electrician for sure. Man, I'm not sure when, But it's on the list for sure!

[@erikhansen1983]

I may have missed it, but did you just plug the toaster oven into your controller box, or did you have to modify the wiring w/in the oven itself? Thanks again for another great video! I appreciate the effort you put in to help others in this craft.

[@RedBeardOps]

Hey Erik, You can do it either way. If you don't modify the toaster you should set it to it's max temp set point on bake and then let the PID controller regulate the on/off to hit the temp. On mine I ended up re-wiring the toaster so the elements turn on full blast when power is supplied to the toaster.

[@erikhansen1983]

@@RedBeardOps Makes sense. Thank you!

[@leefreemanii2622]

I’m trying to put mine together right now, did you drill a hole in the side of the oven to add the thermocouple

[@RedBeardOps]

Yep, I sure did.

[@Pyrichia]

Looks good. However, considering the amperage, don't use the PID controller terminals as terminal blocks to put multiple wires together. Use a proper terminal block, they're rated for it. If that terminal loosens, and it probably will because it's not super high quality, you can get heating there and thermal runaway, or just a faulty, intermittent connection.

[@RedBeardOps]

Good tip!

[@alandust2188]

Hey, great info BUT the diagram you show is different than the Inkbird ITC-106-VH because yours shows the thermal couple on 9 & 10 for the REX-C100 and the Inkbird thermocoupler PID pins are 3 & 4. Sorry but I'm new to this stuff. Do you have one for the Inkbird ITC-106-VH.

[@RedBeardOps]

Hey Alan, I do not. The inkbird should come with a diagram though. If not you should be able to find one online for your specific model.

[@nagut01]

Is it necesary to use heat sink with the ssr ? I'm using one with low wattage consumption in other project.

[@RedBeardOps]

[@markramey5437]

Hey Red Beard, are you running a separate power supply for the oven fan? Just adding a separate switch for the fan, while isolating it, is still getting it's power through the PID if I'm looking at this correctly. Also, is the idea to run the fan consistently while the oven is running? Thanks again. Great video!

[@RedBeardOps]

The fan had a separate switch and power plug in this situation. I thought it was a good idea to not have it turning on and off. All that being said, I don't even run the fan anymore and have great results.

[@davidellison4750]

Nice project. A question, you have a heat sink inside a sealed plastic box. Does the temperature inside the box rise and would it be better to ventilate the box to allow the warm air to escape?

[@RedBeardOps]

Hey David, yes the temperature in the box does raise for sure. I do think a fan would be a great improvement on this design.

[@davidellison4750]

Certainly a fan would work but if one had holes or some wire mesh, one might get sufficient convective air flow across the heat sink to cool without the need for the fan.

[@davidellison4750]

I made my box from plywood. I had a couple of wire screens that you’ll have seen on computer power supplies. They have 4 rings for screws and they are designed to cover a 3” hole. I used a hole saw to drill a 3” hole in the bottom of the box and another on the top of the box, they are directly below and above the heat sink. I’ll put feet on the box to lift the box off the surface which should allow air to freely enter the box, so air should enter the box from the bottom, pass over the heat sink, then the warm air should rise and exit through the upper hole. Thank you for all the time and trouble you put into this. I don’t have a fuse but Amazon has a small 15A breaker www.amazon.com/gp/product/B002PXG1BC/ref=ox_sc_act_title_1?smid=A1UOBWSFLOXPFW&psc=1 for $6.53 so I’ll put that in when it gets here.

[@RedBeardOps]

[@jjppres]

Hi, Hoping your still checking comments on this. I have several questions on this. #1 What did you disconnect on the toaster over to allow the pid to take over. #2 There are several parts you don't list on the parts to buy can you help out with these? They are the heat sink, the fuse and the large job box. Did you get them all on Amazon as well. My toaster overn makes me crazy it varies up to 45 degrees sometimes. I am notelecto mechanically inclined at all. I can wire a house but do not understand this stuff but I want to attempt to make my own pid controller. Any help would be greatly appreciated. Thanks!

[@RedBeardOps]

Hey Jim. 1.) You technically don't have to disconnect anything on the toaster for this to work. You can turn your toaster on to "bake" and then to it's max temp; then plug it into the PID control box. The PID control box will then regulate power to the toaster to maintain the temperature. On my specific build I took off the "bake dial" and the timer that was built into the toaster. I then wired the toaster to a switch on the front panel that acts as an on/off switch. If I were to plug this toaster into the wall in this condition it would be on full blast. 2.) Here is the project box - amzn.to/2oP2mrM 3.) The heat sink came with my SSR and I bought some fuses locally at the hardware store; but both could be found on amazon. 4.) As far as advise goes. Take your time! Also make sure to print out that wiring diagram so that you can follow along easily. I got my terminal connectors from Harbor Freight and they make the project easier too. Good luck!

[@RedBeardOps]

Cool deal! I wired mine to it's own separate switch.

[@davidaustin6657]

What did you do with the factory wires running to the fan? Cap them or connect them?

[@RedBeardOps]

David Austin if I remember right I extended them so that they could reach the dedicated switch on the back of my unit. In reality I’m not sure how much the fan really helps the system, but I like the idea of it being there. I separated the fan from the PID controlled system so that it would run full time instead of on and off with the controller. I doubt it would be the end of the world to run it on and off with the controller though,..

[@davidaustin6657]

I am wiring my box up exactly how you did. Can you send me a wiring diagram of your oven? I see you cut away the top two knobs on your oven and would like to see how you used the PID to control it.

First of all I'm not an electrician so that what I say with a grain of salt... this stuff is dangerous so be carful a1.) You can plug your oven into this with the max temp selected on bake and the box will turn the power on and off to your oven to get to the temp. a2.) I wired my elements direct... and bypassed the panel on my oven. This is obviously a little dangerous so once again be carful. b.) Not a pro at building stuff like this, but I think the system is grounded via the ground on the 3 prong plug. If you find out more let me know.

[@stanjepson2054]

Can you put two PID's in project box for a KIln and a toaster oven ?

[@RedBeardOps]

I'm sure you can!

[@alexiben6871]

Does the box then wire straight into your heating element? Curious to know if there was any other complexities on the oven side. Thanks!

[@RedBeardOps]

It's designed so that you can plug your oven into it; then turn the oven to max bake and have the box control the power. That being said, in my case I bypassed the oven's control and wired the elements straight to the plug. Do at your own risk!

[@alexiben6871]

@@RedBeardOps Ok thankyou!

[@thomasnorton316]

How did you hardwire your switch on your oven? Power coming in to your switch then straight to your elements?

[@RedBeardOps]

That is correct. It's not necessary, but I did it

[@TheRedhawke]

I really enjoyed the video but what do you do to the inside of the toaster oven to attach it to the project box ?

[@RedBeardOps]

TheRedhawke hey man. In reality you don’t need to do anything to the toaster. You can take a brand new toaster, plug it into the box, turn the power switch on, and then turn the toaster controller to max temp. The PID box will then control the toaster.

[@TheRedhawke]

@@RedBeardOps Cool, will the onboard timer turn the toaster off or will the PID keep it heating until you turn it off ?

[@RedBeardOps]

​@@TheRedhawke If you have a timer on the toaster that could be an issue. You would have to visit your toaster 1/2 way though your tempering cycle and "top off" that timer again so that the unit does not turn off. What I did on mine was remove the timer and put the whole toaster on an ON/OFF switch so that this was not an issue. If you don't want to deal with this, I'd recommend buying a toaster without a timer or one with a timer much longer than your tempering cycles.

[@ThePARTHI91]

Can i use this as pcb reflow oven?

[@RedBeardOps]

I'm not exactly sure what a reflow oven is, but this thing will hold pretty darn flat temps. I think you can.

[@tarahgudmundson3532]

Do all PID's need an SSR? Also, is there any other way to tell what the PID is doing besides taking a bunch of plot points and putting them into excel?

[@RedBeardOps]

Some PIDs have data exports... so you can plug them into a pc live. I think some PIDs use mechanical relays instead of SSRs... Sorry if neither of these points are helpful ... I don't know a ton about this stuff other than what I built.

Hello, Red Beard Ops Find your work very well what you do is just great. And I've also built a lot of yourself. I am also building a box with the Rex C100 temperature controller and have done everything as shown in your video. Only what I do not understand is how the oven is connected to the socket of the box, what I have to consider how I connect this. Could you maybe give me a tip or a description I just can not get on with it would be nice if you can help me. lg. from Germany Michael Becker

[@RedBeardOps]

Hi Michael from Germany! So the oven has a power cord coming off of it that would normally be plugged into the wall. When you build the box, the PID control box acts as an intermediary between the toaster and the wall socket. The PID box will have a female plug to accept the power cord from the toaster. The box will also have a male cord to plug into the wall. The PID control box will dictate if the toaster is either on or off based on the temperature being read by the probe. Hope that helped.

Hey man, I'd suggest going back over the manual for the PID and the wiring diagram. If both of those are right, maybe some faulty equipment?

[@nkcwilliams]

I dont see the 15 amp fuse in the list. Which one did you get?

[@RedBeardOps]

I'm fairly sure I bought that item locally. You could probably find it at the hardware store or on amazon.

[@nkcwilliams]

@@RedBeardOps Ok cool I will try ACE Hardware. Another quick question. When you wired the oven for just a on/off switch did you cut out the fan too?

[@RedBeardOps]

@@nkcwilliams In my case I put the fan on a separate independent switch. This is not necessary. You could plug in a fully stock oven into this PID control box and have success. You would just want to make sure that the oven is set to ON and BAKE and max out the temp. The PID will essentially turn the oven on and off to achieve the temp desired.

[@TheDogWalksTheDog]

Is there an easy pid solution install I’m not an electrician. ?

[@RedBeardOps]

Hey Tim, I'm not either. You can buy PID control boxes already assembled. This is what I found on ebay without looking too far into the details - www.ebay.com/itm/Plug-Play-PID-Programmable-Temperature-Controller-Box-SSR-Kiln-Annealing-Glaze/122176024466?hash=item1c72422f92:g:RYAAAOSwPhdU1l0M

[@Aaronyavcm]

I'm debating whether to do this or not.. I'm having a hard time bringing my evenheat temp down enough to temper after quenchig. The fire brick retains so much heat that I overshoot 400°. I came in to check on my first temper cycle today to find the temp sitting at 450°. :(

[@RedBeardOps]

Damn, I always wondered how fast those would come down to temp. One day I'll have me a nice fancy even heat, but I reckon I'll keep using this PID toaster for tempering.

[@Aaronyavcm]

I place a fire brick into the kiln to draw heat and put a fan in front of the oven. It still takes 20 mins or so to cool down.

That's a huge box for so few components. Proper cable management, component location, component selection and strategic wiring are all key. Never epoxy anything, replaceabilty is paramount. Thise self tapping screws scare me. Onexwire comes loose and it's a shock hazard.

Sorry to bug you again but I am in the process of writing the box and am a bit puzzled because on the PID controller I got (the inkbird you reccomended) the #2 spot is a blank. There is nowhere to attach a wire in the #2 spot. 2 and 7 are both blank. I am trying to follow you directions which are great because I would otherwise know nothing about this kind of wiring. Can you help me again please?

[@RedBeardOps]

Hey Jim, I don't own an InkBird, however, based on my research they are superior to the REX controllers. I'd advise reading the instructions manual that came with it or searching InkBird PID controller on youtube to find a wiring instructional video for that specific controller. It's going to be the same concepts as the REX just with different terminal numbers. There should be a diagram in the box that came with it to show you what terminals are what.
