Happy Weekend Kurtis, Karen and Homeless.......always love what you are up to..... can't wait to see you do some grinding with that Badboy... best wishes from the other 'Sunshine State' ........Old Man .Paulie
Am I the only welder that shuts his eyes when Kurtis is tacking stuff together. I know I won’t get arc eye from 12000 miles away but habits die hard.❤️🇬🇧
The deflection shield is actually genius, I'm a hvac tech and a cone in the centre would actually make all fume extractors more effective by reducing the extract area to increase the perimeter airflow, massively increasing your capture velocity near the edges which is exactly what you want. I'm gonna test it out myself in work to measure the differences and do some smoke visuals. Thanks a bunch!
The accuracy of your work, and the care you so obviously take, is brilliant. I’m an old f*rt from the U.K. who can’t knock a nail straight into a piece of wood and I’m in absolute awe of your skills. I watch a lot of TH-cam videos, and yours are definitely up there in my top five - if not in my top one! Karen’s skill in her camera work and editing never seems to get the recognition it deserves. Thank you, Karen. Without you, this channel wouldn’t be what it is. Excellent work!
My son Micah is your absolute biggest fan. He has autism and he only watches, plays with, or reads Sesame Street; except at bedtime when he put on Kurtis and CEE and that’s our NIGHTLY routine. We’ve now watched every episode and handful of times and they never get old for him. His 4th birthday is tomorrow and we’re hoping for a new upload for bedtime tomorrow! ❤
Hi Curtis, as a CEE fan I would like to make a suggestion: If you reverse things, leaving the exhaust fan at the source and not at the end of the duct, the efficiency will be much greater. Congratulations and greetings from Brazil
I don't think so, it requires more airflow. It's hard to suck as there is no direction where blowing has a focused airflow. I was wiring a metal fab shop that also painted the grain legs, fertilizer plant and seed cleaning structures and catwalks. They tried to do a down draft system with 3 large 3 phase fans sucking through 14" pipes out of a vault (like mechanic shops) in the floor. It sadly failed miserably and they did have supply ducts from above to help with directional airflow so they were not starved. But the direction was ever so slight it was conpletely ineffective. It just required much more volume of airflow but for a big bay it's almost impossible. They considered a cyclone which is a very large/ expensive fan for moving grain. A tunnel effect is required where all the air that is soiled is ran through a tunnel, not just sucked from open room. Computer/ PCs are often pathetic by DIYers trying to cool them as they don't have directional flow, just a ton of fans fighting each other allowing the heat created by CPUs GPUs and memory to stay and swirl at best. Less fans and more attention to focused airflow "washing or shearing" away the heats is much more effective making the case tunnel. A totally perforated PC case is a bad thing versus a solid wall case with intelligent fan placement direction. This is why I believe spray booths are only big enough for the items to be painted with ginormous airflow. All the moving air is collecting paint In Curtis' position it's obviously impossible to create a tunnel, but a bigger fan would expand the "directional airflow" further towards the lathe. Regardless he looks pleased with the current setup and that's all that matters. Armchairing a lot here but this has been my experience. I have three was more smaterer friends in their 50s that deal with all things PCs and the photos they share of DIY PC builds brought to their shop for hardware issues is hilarious how useless they are.
You make a lot of tools yourself in order to be able to carry out corresponding jobs. I really appreciate that, here in Germany you often hear the saying that workshops can't do things because they don't have the machine, the tools or the staff that could do something like that. Especially when things get a little more complicated. You have the complete package, an extremely talented craftsman, a suitable machine park and if something doesn't fit, it will be made to fit. I'm really impressed.
Back in the 1960s an Atlas Copco compressor mechanic was on site setting up 6 units, overnight his tool kit was stolen. OK the normal tools could be bought off the shelf but it was the specially adapted spanners etc. that only did one job on one model of machine that had taken years for him to make. Luckily some were found nearby, our company gave him a cash payment to replace his kit.
Nice project. I always enjoy your shop built tools. Couple of comments if I may. 1. Filters are only really effective up to about 500 feet/min. You will of course get particulate in there, but its really just catching the big stuff and acting as a spark arrestor. A better material selection would be metal mesh filter material. I can foresee some hot material falling on that carbon filter material and causing it to smoke. If the embers make it through the filter material (and they will), it'll burn holes in your flex ducting. That material is probably fire resistant and self extinguishing so you won't have an active fire, but pinholes in the ducting reduces the draw by the fan as the pinholes leak air into the duct. 2. That center deflector isn't really doing anything to enhance the draw of your air intake. If you had mounted the exhaust fan intake behind the deflector plate, you would get more even draw around the plate. as it is you are really only drawing off the bottom and any smoke and material that is at the top of the hood is probably escaping as there isn't adequate velocity at the top of the plate to draw it down other than particulate by gravity or deflection. 3. The fan static available by those small blowers is low and the pressure drop induced by the fan flex ducting is high. You will get better performance overall out of the fan if you stretch out the duct to make it as smooth as possible. 4. When using a distributor/deflector plate like that, you typically want to have the air velocity at gap between the hood and the plate at 100 ft/min or more. This ensures a good 'draw' at that gap. Again, your air intake is at the bottom rather than the back, so you aren't getting much performance from anything other than the bottom. In the end, you have something that works for you and is MUCH better than where you were before. Keep up the good work!
Another easy way to increase airflow is to put some spacers under the filter, so air gets drawn through the entire filter surface, instead of only the circular cutout above the duct
@Taroodin some may want to consider a push-pull system, there are ways of modeling throughput & flow but it will require some tinkering and gages to figure out. Utilizing the venturi effect may yield some improvements too. Other oddball ideas ive had included using a Tesla valve to moderate flow.
Good post. I'd trial a few simple baffles to better distribute the draw around the deflector. Or chop it off the legs and trial it the other way up. Filter at the top.
Hello Kurtis! I worked as a CNC bending machine operator for almost 20 years. From practice, I admit that bending these types of elements at angles different from 90 degrees was an art. The final effect during assembly often required the intervention of a hammer. Good job! 😊👍
Hi Curtis, Adriaan from South Africa. I did a lot of arc spraying on a lathe before. I made a long bracket from the lathe saddle to mount the gun. I fixed the trigger with a cable tie. Used the feed of the lathe, and I had good results with a consistent layers. Just an idea for big and long shafts. Nice program.
Bracket sounds a brilliant idea, or at least a spring from the ceiling, to hold the weight of the gun, but probably spring would interfere with your winch.
Holy crap Batman, if this is just an extraction fan shroud I can’t wait for the Franna crane cab, guards and other tin work on that will look like. Job turned out awesome Kurtis, one thing I love about you mate is you do everything spot on, no short cuts and it reflects in your products and finishes, much like Karen with her editing. Have a great weekend guys
I agree!! Kurtis goes above and beyond on everything he does! The man is truly a professional and proud of the work he does and it most definitely shows!!!
Karen, what editing, you can't even see it anymore, its so fantastic. The transitions are just perfection, only for the bloopers you could be fooled into thinking 1 take!😂
@@johncarroll520 I agree with you wholeheartedly, but my personal point of view is a little different. I always bail out when the outtakes start. They’re not to my taste, although I can appreciate why lots of folk like them.
One thing I appreciate about your videos is and explanation of a problem, a voice-over during the process and a final resolution to an issue and even testing of the construction when it's feasible. I feel most of us dislike multi-part videos a week apart. At least for me, multi-part videos when followed up each day with another episode is much preferred. Thanks.
everyone's heard the old adage "a grinder and paint make me the welder I ain't" but I'll be damned if you aren't the welder we all aspire to be😁 Cheers from an aspiring young machinist (and big fan of your work) in Massachusetts, USA!
Need a tool....Make a tool. Phenomenal example once again of your talents Kurtis doing just that. Thanks to Karen's amazing ability to capture it in a way that the rest of us not so engineering sorts can follow, the Friday night beer was well accompanied. 👍 Cheers Pete' New Zealand.
Any confined space extractors make life bearable. I applaud the people that have them. Probably drill out a few holes to increase venture effect. Happy hound.
Great job, as usual, but what I really love is the breakdown of prices that you give at the end. Very, very interesting. Looking at the exchange rate, and, assuming that Oz does not have any hidden b/s taxes added on , it would make prices comparable, if not cheaper than the US! As always, to both of you, thanks for the educational entertainment in your vids. And, well “Homey” he is just icing on the cake !!! Most sincerely, Rod
I know this is a few days late...but I think we can all say thank you to whoever is filming, editing and putting these videos out. Not a lot of people will know how long it takes to film, organise footage, then edit a 53 minute video. It can be as demanding, and time consuming as milling, welding and cutting all the shit we see in the videos. So, again, thank you. You're a star, mate.
I attrribute that vibe to Karen's editing of showing just whats relevant, skip the repetitive stuff, fast play over the mundane moments. Thanks, Karen.
Viewing your and some other workshops channels, its great for hobby education! I've taken old metal door frame and build from it a sand bunker in our yard - no more dirt and roots inside a sand! Cheap electrode weld, electrical grinder and some other staff with right directed hands. Thank you for great videos for resting time, and great motivation for some things to do!
@CuttingEdgeEngineering Great extraction hood. As a retired HVAC mechanic. I can suggest a few small upgrades to improve it. On the bottom filter opening, if you add a small lip (20-30 mm, 1 banana) up into the hood area, it will stop pulling in more of the metal particles into the filter, keeping them in the bottom and still keep cleanup easy. It may also help pull slightly more air from the top. Of course an even taller lip will help pull more air from the top For your filter, it looks like a standard 2 inch height. If you make a pleated filter frame, it will increase the filter material area lowering the pressure drop across it, increasing air flow. That also slows air flow through the filter which can improve its filtering ability and increase run time before clogging. Lastly, I saw that a lot of the spray was deflecting upwards, perhaps an extended top to over the lathe could help reduce cleanup around the lathe, pull more into the hood. Great video as always..... If you need any advise on how to make a pleated filter frame, Thin flat stock made to fit inside your filter box, weld small round bar staggered top/bottom, in from top/bottom the thickness of the filter material, end bars in about 10 mm from sides/middle of height to allow room for the paper clamps Then you weave the filter material around them, just use paper clamps or thin aluminum strips pinched on at the ends to hold it in pace. Weld on a pull handle for removal instead of that cover.
That filter is tiny. Welding and paint booths as well as portable fume/dust extractors have lots of filtering area. Down draft is an odd choice as well.
I had been thinking similar thoughts - but just from the look of things, not any HVAC experience. A pair of sheet-metal, uh, sheets - hinged along the top and bottom edges of the collector/ hood ; - sized to (just) fit into the collector/ hood ; - the lower sheet rests on the lathe bed to protect it (until experience shows, I'd probably still use the fire blanket too) ; - the upper sheet would need support arms clamped to the frame sides somewhere. At the end of the job, tilt the lower sheet back to the collector body to drop the particles into there for the dust pan. Sweep up, then fold everything away and stow back into it's nook.
Damn! All my years working in garages in a previous life, and I never thought of using the bloody gas bottles for forming! Good job Kurtis! BTW, these vids must take an age to edit - great work Karen!
that fume extractor worked out as you imagined .maybe a cyclonic filter would allow the extractor fan to do it,s job sucking through the filter materiel obviously degraded the airflow considerably . A simple dust extractor cone would also collect the overspray dust particles . This type of dust particle extractor is added to a shopvac for woodworking machines . Sailing UMA - Dan and KIKA . are renovating their sailing yacht and they are using the cyclonic dust extractor design to achieve efficient fiberglass dust and particles collection . Your steel sheet fabrication company did a top quality preparation to your extractor cabinet design .it went together like clockwork . congrat,s to mrs for her hard work and excellent video production and editing . You are looking and sounding more at home with your new teefies .at almost 80 years young I always check out your latest projects .and challenges .
Just a quick tip from someone that designed sheet metal parts for a couple of years. When you have bends meeting up at one spot like on the reflection shield I would recommend to cut out the corner and put a small round hole there. Diameterwise I would recommend 1,5 x sheet thickness. Nonetheless great build 👍🏻
@@bushratbeachbum Allows a tight bend at the fabricator, so that you can have them meet without a bulge, and also allows the bending brake to get the angle consistent right to the corner. Then on assembly you weld up the hole to form a perfect angle, even if you had a slight error in the cuts, it allows it to be removed.
Thank you again for a wonderful journey. Keep in mind that one of many reasons for using a full face mask while welding is protection from UV light. My father had skin cancer and his dermatologist said that his having welded for about a year in the 1940s was a major contributor. Not trying to scold you; just hoping to improve the quality of your life. Cheers, Alan Berlin
Kurtis, this is a solid build and a tool that should last you a very long time. Not to mention, help you breathe better. You and the Mrs, your video's just keep getting better and better and Homie continues to steal the show. Those filters, you should be able to just wash those to make them last longer. Great video as always, cheers :)
Great achievement. As an idea, a protruding metal sheet at the top (sort of a roof, retractable by a hinge) could help to catch more of the escaping fumes.
Love watching your welding. From a D11 dozer to skinny sheet metal, perfect welds. Excellent fabrication too True craftsmanship . Thanks for bringing us along. And thanks Karen for superb videography!
Dude, I can't remember if i've said it, but if I did it bears repeating. You look great, man. Your entire face shape has changed with your dental work and you look happy and healthy and I'm so happy for you man. I know dental pain is a whole other type of pain, and I know you've got to be feeling so much better. I hope you're well, and I love your stuff.
If you take the diffuser off, you could put yer telly in it!🤣😂🤣😂. Great idea, great build, very effective! Your programme give me inspiration to do things about my own place, so thank you for that!👍😁
Kurtis , without being repetitive I have to say yet another triumph , that will certainly help to keep the crap out of the shop well done you two oh and great design .😊
Curtis without question, your skills and broad knowledge are truly world class, The best of the best. God Bless you, Karen and the team that make this U-Tube channel a premium channel. Let me not forget Homeless and his part of needed entertainment to the program. A++ production.🇺🇸 in Pennsylvania
Hey guys. Here basically on time. Hope everything is great with you. Looking forward to seeing Kurtis's super skills and watching Karen's video expertise. Nothing better on TH-cam! Cheers!
Another great build. Consider adding a couple of hinged extensions to the front of the hood. Top and right side would catch more smoke and splatter, bottom would help protect the ways and simplify clean up. (A quick dusting of a flat surface instead of having to clean the bed and/or blanket.) And hinging them would allow them to fold out of the way for really big pieces and for storage.
Laughed out loud at the pull starting of the angle grinder. That was great! Can't help it! Every time I see you using the Metal Arc Sprayer, I think "Buck Kurtis from the 23rd and a half century!"
When Kurtis was standing there holding the sprayer he looked like a poster boy for a space video game with a spaceman firing his ray gun. Patent this design quickly before someone else does.
Curt- You made an interesting comment about parts fitment. I have noticed that on many of your projects you lots of test fitting before executing the final assembly. I do the same thing with my static WWII Aircraft Models, (1/32 Scale). I will say this, I find watching your You Tube Channel interesting and enjoyable. Australia is on my bucket list to come and visit. Your shop is on that list. Keep up the good work...
I love the outtakes at the end. the amount of shit he's good at and machining and welding prowess is awesome, but the hilariousness of the bloopers seals the deal. homie's also pretty freaking great, and karen's editing also. shoot, the whole channel is awesome
Bravo,you did an outstanding job designing and building a very useful addition to your shop. Your attention to detail clearly shows in the finished project. The blue paint and the CEE stickers top it off. The camera op did her fantastic job as usual. Thanks for another great video, I enjoy them very much.
Add an extended roof and walls with a half circle cutout in the walls so it wraps around the spinning part thereby being closer and catching even more fumes and sparks. It seems to be a little too faar away. ALSO seal up the gaps in and around the filter to get even better suction! I really like the blue color with those stickers! :D
Dang, I miss welding so much. I welded for a living until my back went out from some old military injuries. If I could afford a small welder for the home and maybe a drill press minimum, I'd do so many little projects to keep myself occupied. Until such a day comes I'll be sitting right here on TH-cam just watching people like Kurtis manufacture things. :D
Can always add them later on though, as the metal is heavy enough to handle a set of hinges there, and with removeable pins they can be taken off when not needed, or have varying length ones. Back of unit perfect place to store them as well, just add in a pair of pins and holes in the flaps to match. Just need 3, 2 narrow ones and a single wider one.
It's a cool design and well executed. I probably would have added gussets where the stand is welded to the box, which might be overkill. Thanks for the weekly video, always a pleasure.
I am 99% sure your saw issue is the capacitor. The capacitor is required to get the motor up to speed. It's very easy to replace them and inexpensive. I would try that first before calling in an electrician.
No video? I am concerned. I hope there’s nothing wrong with you two or Homey. It’s none of the world’s business,but it’s important for you to know some viewers care.
Hey Kurtis, I suggest closing off the whole bottom of the deflector front & sides and see if you get a better negative air pressure, thus drawing more smoke and debris. The area of the tube is 707 square millimeters, so the area of the space around the deflector shield should be less area than 707 millimeters to create a lower air pressure, which means faster air flow. If closing the bottom and sides at the bottom is not enough, add adjustable baffles on the top and sides. Try to achieve 566 square millimeters (20% less than 707) of space between the deflector and the shell & none at the bottom front & sides. If you just close off the bottom front and sides, you will still have approx. 487,700 square millimeters of space between the deflector and the shield, adding the top and sides as they are now. Keep the fan and make changes as I described, as math does not lie.
We're excited to get this system built, setup and running so we can continue making the most out of our new metal arc spray machine! Something we'll probably look at changing in the future is the exhaust fan to one with more performance and higher airflow volume - but now that you've seen how it's done, let us know any suggestions for improvements in the comment section!😉👍

@@marioduarte7658 exactly. It's a blower, not a sucker. The ducting also is not designed for suction. It works but not as well as it could in reverse.

@@johncarroll520 I agree with you wholeheartedly, but my personal point of view is a little different. I always bail out when the outtakes start. They’re not to my taste, although I can appreciate why lots of folk like them.
You've made the Friday morning my favorite time! Coffee watching Kurtis do his magic! Cheers from 🇫🇮
Glad you enjoy it! have a great Friday
Same for me 🇷🇺
Your attention to detail is second to none, especially as this is just a tool for the workshop and not for a client
One thing I appreciate about your videos is and explanation of a problem, a voice-over during the process and a final resolution to an issue and even testing of the construction when it's feasible. I feel most of us dislike multi-part videos a week apart. At least for me, multi-part videos when followed up each day with another episode is much preferred. Thanks.
Roll on segment #18 of the long-running saga of the "Crane of Doom From The Wash Plant of Coal ! "
everyone's heard the old adage "a grinder and paint make me the welder I ain't" but I'll be damned if you aren't the welder we all aspire to be😁
Cheers from an aspiring young machinist (and big fan of your work) in Massachusetts, USA!
Need a tool....Make a tool. Phenomenal example once again of your talents Kurtis doing just that. Thanks to Karen's amazing ability to capture it in a way that the rest of us not so engineering sorts can follow, the Friday night beer was well accompanied. 👍
Cheers

Any confined space extractors make life bearable.
I applaud the people that have them.
Probably drill out a few holes to increase venture effect.
Happy hound.
Venturi effect.
Great job, as usual, but what I really love is the breakdown of prices that you give at the end. Very, very interesting.
Looking at the exchange rate, and, assuming that Oz does not have any hidden b/s taxes added on , it would make prices comparable, if not cheaper than the US!
As always, to both of you, thanks for the educational entertainment in your vids. And, well “Homey” he is just icing on the cake !!!
Most sincerely,
Rod
There's no extra BS taxes 😂 and the build cost converts to around $620 USD
I know this is a few days late...but I think we can all say thank you to whoever is filming, editing and putting these videos out. Not a lot of people will know how long it takes to film, organise footage, then edit a 53 minute video. It can be as demanding, and time consuming as milling, welding and cutting all the shit we see in the videos. So, again, thank you. You're a star, mate.
The only YT channel where I see a 53 min video and I think to myself... that's not long enough
I attrribute that vibe to Karen's editing of showing just whats relevant, skip the repetitive stuff, fast play over the mundane moments. Thanks, Karen.
Only ones I can watch end to end no matter how long they are....😂😊🇦🇺
Oh yeah! More shop made tools.
Viewing your and some other workshops channels, its great for hobby education! I've taken old metal door frame and build from it a sand bunker in our yard - no more dirt and roots inside a sand! Cheap electrode weld, electrical grinder and some other staff with right directed hands. Thank you for great videos for resting time, and great motivation for some things to do!
@CuttingEdgeEngineering Great extraction hood. As a retired HVAC mechanic. I can suggest a few small upgrades to improve it. On the bottom filter opening, if you add a small lip (20-30 mm, 1 banana) up into the hood area, it will stop pulling in more of the metal particles into the filter, keeping them in the bottom and still keep cleanup easy. It may also help pull slightly more air from the top. Of course an even taller lip will help pull more air from the top For your filter, it looks like a standard 2 inch height. If you make a pleated filter frame, it will increase the filter material area lowering the pressure drop across it, increasing air flow. That also slows air flow through the filter which can improve its filtering ability and increase run time before clogging. Lastly, I saw that a lot of the spray was deflecting upwards, perhaps an extended top to over the lathe could help reduce cleanup around the lathe, pull more into the hood.
Great video as always.....
If you need any advise on how to make a pleated filter frame, Thin flat stock made to fit inside your filter box, weld small round bar staggered top/bottom, in from top/bottom the thickness of the filter material, end bars in about 10 mm from sides/middle of height to allow room for the paper clamps Then you weave the filter material around them, just use paper clamps or thin aluminum strips pinched on at the ends to hold it in pace. Weld on a pull handle for removal instead of that cover.
That filter is tiny. Welding and paint booths as well as portable fume/dust extractors have lots of filtering area. Down draft is an odd choice as well.
I had been thinking similar thoughts - but just from the look of things, not any HVAC experience.
A pair of sheet-metal, uh, sheets - hinged along the top and bottom edges of the collector/ hood ;
- sized to (just) fit into the collector/ hood ;
- the lower sheet rests on the lathe bed to protect it (until experience shows, I'd probably still use the fire blanket too) ;
- the upper sheet would need support arms clamped to the frame sides somewhere.
At the end of the job, tilt the lower sheet back to the collector body to drop the particles into there for the dust pan. Sweep up, then fold everything away and stow back into it's nook.
Damn! All my years working in garages in a previous life, and I never thought of using the bloody gas bottles for forming! Good job Kurtis! BTW, these vids must take an age to edit - great work Karen!
And the bugger is he's got the support blocks already cut.
Plus he already did PI x D.
@@tonyandjackieholmes9546 Safety stands for the empty cylinders, cant fall over if it already is in sleep mode.
@@bostedtap8399 Exactly! Probably a banana pie.
Just remember ... O2 bottles good. Acetylene bottles bad.
that fume extractor worked out as you imagined .maybe a cyclonic filter would allow the extractor fan to do it,s job sucking through the filter materiel obviously degraded the airflow considerably . A simple dust extractor cone would also collect the overspray dust particles . This type of dust particle extractor is added to a shopvac for woodworking machines . Sailing UMA - Dan and KIKA . are renovating their sailing yacht and they are using the cyclonic dust extractor design to achieve efficient fiberglass dust and particles collection . Your steel sheet fabrication company did a top quality preparation to your extractor cabinet design .it went together like clockwork . congrat,s to mrs for her hard work and excellent video production and editing . You are looking and sounding more at home with your new teefies .at almost 80 years young I always check out your latest projects .and challenges .
Just a quick tip from someone that designed sheet metal parts for a couple of years. When you have bends meeting up at one spot like on the reflection shield I would recommend to cut out the corner and put a small round hole there. Diameterwise I would recommend 1,5 x sheet thickness. Nonetheless great build 👍🏻
To allow easier fit up?
Or something else?
@@bushratbeachbum Allows a tight bend at the fabricator, so that you can have them meet without a bulge, and also allows the bending brake to get the angle consistent right to the corner. Then on assembly you weld up the hole to form a perfect angle, even if you had a slight error in the cuts, it allows it to be removed.
35:17 that transition yoooo that was fire 🔥.
I think Curtis actually shielding the additional rays with his cap. ❤
Thank you again for a wonderful journey. Keep in mind that one of many reasons for using a full face mask while welding is protection from UV light. My father had skin cancer and his dermatologist said that his having welded for about a year in the 1940s was a major contributor. Not trying to scold you; just hoping to improve the quality of your life.
Cheers,

I'm afraid this video will be the highlight of my weekend.
I really liked how your perfectionism didn't allow the stand to remain crooked inside this structure (on 9:54). Respect :)
That tank roll was smooth as butter.
About as perfect as imaginable.
Kurtis, this is a solid build and a tool that should last you a very long time. Not to mention, help you breathe better. You and the Mrs, your video's just keep getting better and better and Homie continues to steal the show. Those filters, you should be able to just wash those to make them last longer. Great video as always, cheers :)
Great achievement. As an idea, a protruding metal sheet at the top (sort of a roof, retractable by a hinge) could help to catch more of the escaping fumes.
😎👍👍👍👍👍
Who couldn't love that giggle!
Good demonstration of proper fit up and preparation. The attention to details resulted in a professional looking product!
Glad to see the subscriber count always increasing. Can't wait to see you hit the 1M! Great video as always.

Must have done that for the camera. You’re a legend!
Love watching your welding. From a D11 dozer to skinny sheet metal, perfect welds. Excellent fabrication too
True craftsmanship . Thanks for bringing us along. And thanks Karen for superb videography!
Kurtis always builds stuff that is spot on, looks professional. He must be very proud of his work!
8.00 UK time best way to start a Friday 😊
9 MEZ also perfekt
10:00am Kenya Aast Africa, perfect Friday
Me too, and I'm still in bed 'cause I've got the dentist this morning.
Same here in Yorkshire, in bed with my first coffee. So enjoying retirement.

CEE: start selling these shop made tools. You have some outstanding practical designs for these things that no one else has out there.
Dude, I can't remember if i've said it, but if I did it bears repeating. You look great, man. Your entire face shape has changed with your dental work and you look happy and healthy and I'm so happy for you man. I know dental pain is a whole other type of pain, and I know you've got to be feeling so much better. I hope you're well, and I love your stuff.
39:22 two pairs of safety glasses, extra safe 😂
Safeception.
I love how the video already have 16K views in the first hour. Another Great CEE Video for us to enjoy.

Absolute Master Class on sheet metal welding. Wow!
If you take the diffuser off, you could put yer telly in it!🤣😂🤣😂. Great idea, great build, very effective! Your programme give me inspiration to do things about my own place, so thank you for that!👍😁
Great job on the Booth nicely done Kurtis and Karen and Homey 🐕❤️👍. Take care of yourself and family and friends and be Blessed ❤️.
This projects gives me a lot of ideas for dust extraction on my wood turning lathe. Great build and video.
0:15 👏👏👏OH BOY, OH BOY! NEW TOYS, NEW TOYS!🥰🥰🥰
NINTENDO 64!😂
Kurtis , without being repetitive I have to say yet another triumph , that will certainly help to keep the crap out of the shop well done you two oh and great design .😊
Curtis without question, your skills and broad knowledge are truly world class, The best of the best. God Bless you, Karen and the team that make this U-Tube channel a premium channel. Let me not forget Homeless and his part of needed entertainment to the program. A++ production.🇺🇸 in Pennsylvania
Great to see a bit of thought going into health and safety👍👍👍
Hey guys. Here basically on time. Hope everything is great with you. Looking forward to seeing Kurtis's super skills and watching Karen's video expertise. Nothing better on TH-cam! Cheers!
Another great build. Consider adding a couple of hinged extensions to the front of the hood. Top and right side would catch more smoke and splatter, bottom would help protect the ways and simplify clean up. (A quick dusting of a flat surface instead of having to clean the bed and/or blanket.) And hinging them would allow them to fold out of the way for really big pieces and for storage.
I was going to make exactly the same comment
I have to agree. You get could a lot of mileage just from breaking down a cardboard box and making a cheap hood extension on the top and right.
I was going to suggest it 👏👏👏
@@kiwishamoo6494 I had the same thought.
@@jimwinchester339depends on how hot that spray is. I know metal sparks aren't good heat conductors but that's a lot of sparks.
Been loving the shop made tools series so far, keep up the great videos!
Kurtis in addition to being a great machinist, is also a great designer.
Fantastic machine Kurtis! Well done!
Before you get the sparky in, see if the bandsaw blade has been jammed with swarf somewhere.
Bravo Kurtis, ottimo lavoro come sempre!
finally this has become a woodworking channel!
I'm disappointed Kurtis didn't use a grinder to trim the plywood.
*Cutting Edge Engineering Australia* Hi guys always a pleasure to see you both, thank-you for taking the time to bring us along. GOD Bless.
Laughed out loud at the pull starting of the angle grinder. That was great! Can't help it! Every time I see you using the Metal Arc Sprayer, I think "Buck Kurtis from the 23rd and a half century!"
I’m liking the hand print in the final shot 🙏🙏
When Kurtis was standing there holding the sprayer he looked like a poster boy for a space video game with a spaceman firing his ray gun. Patent this design quickly before someone else does.
Time for another episode of seemingly random bits of sheet metal that Curtis turns into something awesome!
Brilliant as ever! My love to Homeless!
i like the way you make it simple even though you put alot of time in off camera working on the design. keep up the good work.
truly a work of art...😁
Safety squints have entered the chat!! Great project Kurtis and very useful. That hood looks like my Sony HDTV of the 90's!
Still got that TV.
Here we go! Good morning my friends!
no better way, to start the day with a good coffee, a sandwich and a CEE video with Kurtis improving the shop ^^
Morning all
let's go
It's 1am here.
Morning 😊
Love the signature CEE blue!
Curtis breaking out the carpentry skills for the win!
Curt- You made an interesting comment about parts fitment. I have noticed that on many of your projects you lots of test fitting before executing the final assembly. I do the same thing with my static WWII Aircraft Models, (1/32 Scale). I will say this, I find watching your You Tube Channel interesting and enjoyable. Australia is on my bucket list to come and visit. Your shop is on that list. Keep up the good work...
I love the outtakes at the end. the amount of shit he's good at and machining and welding prowess is awesome, but the hilariousness of the bloopers seals the deal. homie's also pretty freaking great, and karen's editing also. shoot, the whole channel is awesome
Bravo,you did an outstanding job designing and building a very useful addition to your shop.
Your attention to detail clearly shows in the finished project.
The blue paint and the CEE stickers top it off.
The camera op did her fantastic job as usual.
Thanks for another great video, I enjoy them very much.
Cool! You made a welders TV!
Ita a a CRT unit.
Those birbs have trained you well :)
Great post! Greetings from Brazil!
Tin bashing is a most useful skill. You do it well. Thanks for the video.
Add an extended roof and walls with a half circle cutout in the walls so it wraps around the spinning part thereby being closer and catching even more fumes and sparks. It seems to be a little too faar away. ALSO seal up the gaps in and around the filter to get even better suction! I really like the blue color with those stickers! :D
Looks like big TV 👍 I love Your videos! Greetings from Poland 🇵🇱
Dang, I miss welding so much. I welded for a living until my back went out from some old military injuries. If I could afford a small welder for the home and maybe a drill press minimum, I'd do so many little projects to keep myself occupied. Until such a day comes I'll be sitting right here on TH-cam just watching people like Kurtis manufacture things. :D
Yet another excellent project, good idea that you can't get commericaly and look's good too..
You should put hinged flaps on the front edges so you can widen or narrow the catchment area. And fold them flat out of the way when not needed.
And if you put a cone with baffles before the filter material it might last several jobs.
Can always add them later on though, as the metal is heavy enough to handle a set of hinges there, and with removeable pins they can be taken off when not needed, or have varying length ones. Back of unit perfect place to store them as well, just add in a pair of pins and holes in the flaps to match. Just need 3, 2 narrow ones and a single wider one.
Looks like you’ve have just made a large old style 1980s tv on legs Kurtis. Very inventive
I am sure Ron Covell would have approved of your gas bottle bending jig
Old school tvs thats what it reminded me of when you first tacked it together😂 great work as always
Awesome job mate!!! Looks great and works really well. Like it!!
It's a cool design and well executed. I probably would have added gussets where the stand is welded to the box, which might be overkill.
Thanks for the weekly video, always a pleasure.
Small modifications like a hood, couple of wings, maybe. All good and the best
Yeah, hood might be an easy but effective addition
I am 99% sure your saw issue is the capacitor. The capacitor is required to get the motor up to speed. It's very easy to replace them and inexpensive. I would try that first before calling in an electrician.
Your talent continues to amaze me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
These fab projects are the ticket for me. Nice job!
Well Kurtis I look forward to 3pm each Friday for your Video, it's 5pm. What's the GO?
Go see the post on our community page 😉
@@CuttingEdgeEngineering Aww friday ruined.. i guess i'll have to follow Frenna progress from google satellite images 😅
No video? I am concerned. I hope there’s nothing wrong with you two or Homey. It’s none of the world’s business,but it’s important for you to know some viewers care.
th-cam.com/users/postUgkx49AGY6z9NlX9K-tQ19yyQqAS2L3GjfEV?si=-K1jKaLLwjVg3Pc7
Hey Kurtis, I suggest closing off the whole bottom of the deflector front & sides and see if you get a better negative air pressure, thus drawing more smoke and debris.
The area of the tube is 707 square millimeters, so the area of the space around the deflector shield should be less area than 707 millimeters to create a lower air pressure, which means faster air flow. If closing the bottom and sides at the bottom is not enough, add adjustable baffles on the top and sides. Try to achieve 566 square millimeters (20% less than 707) of space between the deflector and the shell & none at the bottom front & sides.
If you just close off the bottom front and sides, you will still have approx. 487,700 square millimeters of space between the deflector and the shield, adding the top and sides as they are now. Keep the fan and make changes as I described, as math does not lie.
Love Fridays.......especially the 13th.....Наздраве!
I like the idea it looks nice well done mate 👍 👍
