- My store-bought furnace has seen better days; replacement parts are expensive and taking the thing apart is a pain. Time to make my own with improvements learned from using the previous furnace.

Get one of those cheap automatic center punches at Harbor Freight. Mount it in a collet in the CNC, and it will do your hole location and center punching in one step. Then program a Z value that compresses the spring but not quite enough to “pop” it; and drive it around your outline to create a score line for bending. The strong spring and the slightly rounded point will give good results in thin sheet metal. I thoroughly enjoyed this video and look forward to the rest.
Can't wait for the next part! great job.
Hi Chris - awesome work. This looks like it'll be an impressive furnace. I love the variety of metalworking projects you undertake, and your 'have a go' attitude. Keep it up :) Ben
Why didn't you try machining the whole sheet metal on the CNC??????
Loving the sound tracks!!!!
I just wanna say...... How impressive CNC machines are. Like, its beautiful to watch it perfectly mark that stainless steel. Thanks for this video man
“Project Stuff” Love it!
solid video! Keep them coming.
Best Matt
Loved the cnc bender.
Nice work. I really enjoyed your video.
I was just thinking as I watched the red marker tracking along, how very good an idea, Im hoping to create something that will work, but not as technically efficient as yours, due to lack of machines.. Thank you for your video.
Sheet metal should bend better if you put small grove on the inside of bend line (should be a bit careful here because too sharp bend can cause metal to crack) and use softer hammer (or put something soft between hammer and sheet) so metal wouldn't deform randomly.
The beginning is a good ad for a furnace
Stubby cobalt drills so good.
super as always dont change a thing stay golden pony boy love you!
+Noway Jerk thanks!
.
I think I would have laid the lines out on the bricks at an angle so the coil could would follow a natural "spiral". Love the precision thermocouple port!
+DASWorkshop That's a good idea but I'm not sure how it would work with step 2. Stay tuned!
Nice one Chris, what metals do you plan on casting in this one?
Oh hey it's you! Your video was my inspiration for doing the four bricks with the angled corners! Love the simple design. :)
Whatever will melt! Mostly copper and aluminum to make some cool alloys that I can use in future projects; mostly for cosmetic purposes. I've done a little silver as well recently, I've started doing graphite molds for silver casting for people and need to test them out.
cant wait for those vids !
Sounds awesome! looking forwards to the videos!
The firebrick is in essence, puffed update sandpaper particle (alumina, Al2O3)
Hey great video i just found you, one question, what is your metal lathe?
Where’s part 2?
The runout is a bit ropey on that sharpie. ;)
It would have been funny if you did the drilling on the CNC too.
"Tool change request: remove 'sharpie', insert '5mm jobber'"... just sound like a funny screen shot to me.
What I do when I have bends like you had is take your grinder with the cutting blade and score the inside of the bend. This lets the metal move into the grove you cut instead of trying to compress the excess metal on the inside of the bend, then you can add a spot weld to the inside of the bends.
One note...You should just take that sheet to some laser cnc shop! They deal with sheet metal like it's nobody's business. Also it goes very fast and they charge breadcrumbs for it!
PS: Also whenever I drill sheet metal at some point it always tries to hack me up but that might be because of the insane runout of my drill press!
sir can you please clear my certain doubts as i am making this. 1.what is the input voltage and current and how much input watt please sir reply
Cool DIY belt sander! I would think that you needed a DIY press brake.
Subscribed 👍
your brake would be moire consistent if you had a reasonable bend radius
Nice editing! The laser cutter must be sad tho
My uncle and I just started working on an electric furnace ourselves. what type of element will you be using and where did you source it from?
I'm using Kanthal A1, 16ga from Temco (on Amazon).
Thats the same wire and supplier we plan on using for our furnace. There is a website that I found about coil size and design and what sort of wattage you should aim for when making your coils. its mostly for kilns and annealing but it does give a pretty decent outline on coil design.

Love the video you do great work! Maybe next time any of the repetitive process you could show the first one you do then skip or quickly fast forward over the rest? Totally up to you I just think it may be a bit more enjoyable to view that way. Either way though I watched the whole thing cause it was awesome!
I did that a fir bit already; I cut almost 10 mins out of my first edit because it was too repetitive. I have yet to find that good balance between too repetitive and just jumping from operation to operation too quickly. Glad you stuck through the whole thing though!
Chris DePrisco you could timelapse all of the routing after the very first one. also the cnc sharpie and the holes drilling.. no benefit of showing 10 holes. do one and then go to timelapse or jumpcuts.
Your content is so good people are going to stick around regardless though. Keep up the great work! Can wait to build mine this summer!
6:50 lol CNC Sharpie
Have you tried putting an automatic center punch in the collet for CNC layout?
Actually, at that point, you may as well spot drill the first 1/2 millimeter. (Since you've got a spindle)
Yea, that would have been a good idea! Since it was just taped down I didn't even consider doing any milling but a spot drill probably would have been fine. Oh well. :P
you could have cut half way through the plate on the fold lines while you were at it, but not everybody has 20-20 hindsight.
Chris Stephens I'll have you my hindsight vision is nearly flawless. It's my foresight vision that's the problem. :)
you, me, and most others i fear.
how many kw does it use?
13:40 "the invisible hammering"
I find it funny that he uses a fancy CNC machine to draw the lines but then cuts everything out with an angle grinder.
just like in wood, if you score along the lines it won't break out as easily.
Is there a link to where I can order those bricks?
They are all over eBay and Amazon. Just look for "Fire Brick" of the size 9" x 4.5" x 2.5" if you want the same as me. The K-xx number is the temperature rating. K-26 = 2,600F for instance.
Thank you. There's several videos saying "this brick" but there's so many types that I'm overwhelmed with trying to figure out which is the "safe bet". Just wanted someone who was successful to say "this brand" so I can feel better about the purchase. Peace of mind kind of thing.
I don't know about brands but so long as they are rated for the heat and are the size you need you should be fine. If you want to use the exact ones I got, they came from Eurotool. I got them fairly cheap through our store but they will still be about twice the price as ebay. If you want them, I can get them for you.
No worries! I really appreciate your offer. I just wanted more specifics. Very timid about the whole thing. Been using coals and am anxious to try something cleaner. Thanks for your quick reply and your consideration.
hello cris. Why do you cancel my comments? do not you have respect for criticism?
nice beats
Took some time, but these are it :P

* edit * well, some of them
Yeah, was really surprised to see a subscription royalty-free library include swing house tunes, even a paid one. Cheers for hunting them down DKTAz00 mate
Have an CNC machine.
Cut sheet of metal by hand
Why not an induction furnace?
Induction is fun but it takes a lot more effort to set up the coils for the different materials, needs some pretty expensive gear to make it work and doesn't do well for general "oven" tasks like heat treating steel. I hope to make one some day though!
if it cant melt steel, its useless.
Cheap but not easy
I hope you did not breath the dust
Thats an expensive sharpie plotter you have there ;)
Stay tuned, there's even better plotter action coming soon!
Please PLEASE tell me you were using a cutting disk on the grinder and not a grinding disk!
They shatter and cut off your face!
WHY THE ACTUAL FUCK DO YOU NOT JUST MACHINE EVERYTHING WITH THAT CNC INSTEAD OF MARKING STUPID LINES WITH THAT CNC I DONT GET IT BUT HEY, IT WORKS!
Christoph Monot seas
Please, don`t use angle grinder without safety guard anymore. We need you.
im the youtube safety monitor and chris has all his no gard certification's but thanks for your concern
yeh, no guard and face right in the firing line, did make me cringe a bit
Excuse me, Noway, but you are needed in the comments section of another 4,395 videos before tomorrow morning.
You say that until you yourself lose a hand and say 'well shit, guess I can't type wanna-be manly comments on youtube to act like a bigshot while being depressed over my lack of social life'
So I call you out on being an internet tough guy...
And you resort to weak personal attacks
Really shows the level of maturity you've reached. Why don't you come back to me when you've graduated elementary school there, buddy?
new idea... methane
Love your videos but please don't do AVE any more. Much prefer you being yourself (Y)
that bottom plate is over engineered as fuck
