Fabulous! I spent much of Friday, till it was too dark to see cutting 1/4 inch plate by old School tech & then filing. Just amazing how far machining has come both in technology & cost. Kind of wonder what Brunel, Whitworth et al would have done with modern tools & yet many find endless things to complain about.
I never even heard of plasma cutters until a little while ago. I ended up buying an everlast plasma cutter and now I don't know what I'd do without it.
Who knows what Myford gonna build now with his new nifty cutting machine, can't wait for him to put out a new video making something outta his new machine, Awesome job Myford :)
This is just fantastic! - Well done David, Your new plasma cutter and cutting jig works really well and it cuts through the 4mm mild steel plate like a hot knife through butter - saving you hours of work and effort if you were to use a jigsaw with a metal cutting blade. Thanks so much for showing me this great video as always ;-) 10/10.
Looking at your brilliant circle cutter idea, i had a flash of inspiration. in the event you need a disc with no hole, you could put a flat head with a live center for down pressure and achieve the same awesome results. You could also make a magnet base for steel, no clamp required. However the magnet would get weaker with each exposure to heat, but Harbor freight has the 2 packs of the round magnets for super cheap, and they work well. Just drill the hanger clip out of the center and you have a mounting hole. Just a thought to expand the functionality of a really great idea.
perfect! I build a circle for my cutter witch is a easy solution but only for bigger disks. Always amazing how perfect the cut culd be, if it's not freehand!
You'll love using a plasma cutter... This is a great source for ideas on how to make circles, affordable to just about anyone with limited resources. Just one detail, your would get better cutting kerf if you make the torch straight or slightly angled towards the direction of cutting. Great videos with good ideas, thanks... ;)
I got to try my friends everlast powerplasma cutter and I completely agree. Once you have used one you really can't help but want one for yourself. Highly addicting.
That is very handy. I like how you can start it and pretty much forget it until it finishes cutting. I will try this with my everlast plasma cutter thanks.
If we want to produce the traction engine you've just added another required item to the shopping list, a plasma cutter. Along with a foundry and the usual workshop this is getting expensive. Buying the kit seems the only viable option. But fun to watch! Regards.
On those straight cuts, are you dragging the tip along the guide or the material? I just got my plasma cutter and I thought you had to hold the tip up so it's not electrically contacting the material.
John Ridley some machines come with a drag tip. My Hobart is not one of them and it goes through electrodes and tips way faster if you drag it. Check your manual.
Dear MB, (D) as ever a top video. Brilliant work and very encouraging to us (me) amateurs 8). ps was wondering if you were going to fry up on the cut metal...
Alternatively you could drill a piece of bar stock with the plasma head diameter on one end and the center post diameter on the other, and manually cut a circle. Similar in concept to how you'd draw a circle with a compass.
+myfordboy your way will definitely make a cleaner cut! Also, ive used Masonite templates for all sorts of shapes, just need to factor in the offset between the plasma and the edge of the torch tip. The Masonite can be used for several pieces before getting too burned up. Thanks for sharing your inventions!
+🔥Ramsey Customs - turbocobra I have a nicer motor than the one used with an electronic speed control and nice gearbox. I used this first. It could be reduced in speed to what i needed but as soon as the torch was fired up the motor ran at full speed. Somehow the electronics in the plasma cutter interfered with the motor controller.
+🔥Ramsey Customs - turbocobra If you can get DC motors with brushes and a variable power supply it would be the best way to make the speed smoothly variable... ;)
+D I think it's great value. I am pleased with the tool. I have cut 1/2" steel, not tried anything bigger. It cuts the sheet great and the finish is good. The circles are very neat. the secret to a neat cut is constant speed. Like when you are turning something in a lathe, it takes a bit of practice to be able to get a constant feed. You need a compressor of course and for full power it won't run off a 13 amp socket as the input is about 20 amps.
I cannot find any safety nanny comments about zinc fumes from the galvanised straight edge. I wasn't going to write one myself. I just wanted to read some. What's going on? This seems most unusual for youtube. Love this channel btw. Thumbs up etc EDIT. OH wait. It isn't galvanised, is it? LOL. X'D
+Stephen Weir It's listed as cutting up to 25mm (model Cut 25) I have tried it on 12mm and it cuts fine. For £140 including delivery i think it's excellent value.
On occasion, you may have to watch out in case the steel has enough carbon in it to get hardened by the heat, especially when cutting unknown scrap bits. Last time I welded that near to my "workmate" it got burnt to a cinder!!!
+Roger Crier I set fire to my workmate once when soldering a large boiler, do I stop and put out the fire or let it burn and not spoil the boiler. You will see my workmate now has new unoriginal jaws.
+Mentorcase You can even cut wood, glass, plastics and etc. if you place a metal sheet on top. Will need to experiment to get good results. Heat glass first or it will crack, wood scorches and plastic melts if too slow. Doesn't work real well for everything but sure is fun to try. Mike (o\!/o)
What a neat Idea Bravo!! What is the motor from - I would guess it's a windshield wiper motor but looks really skookum (Canadian word for robust lol). What type of vehicle would it be from? Also, as I was watching I had an idea that the threaded rod could be replace with a high power magnet. Thanks again David - just your average excellent video! Rod
+Newmachinist The motor is a mains AC ( 240 volt) motor but as it is series wound it works also on DC . I tried a magnet first but when cutting smaller discs the heat from the torch shattered the magnet.

that was the most aesthetically pleasing thing I've seen all week haha beautiful cut!
Absolutely Brilliant! Simple, cheap, adjustable and totally functional!!
theres nothing cheap about geared motors, and adjustable power controllers. Great idea though.
Who knows what Myford gonna build now with his new nifty cutting machine, can't wait for him to put out a new video making something outta his new machine, Awesome job Myford :)

A magnet would work OK and also your other suggestion. No Harbour Freight here in the UK!
perfect! I build a circle for my cutter witch is a easy solution but only for bigger disks. Always amazing how perfect the cut culd be, if it's not freehand!
+66Gollum If a lot of straight cuts were needed it would be quite easy to make a guide driven by a threaded rod with a motor on the end.
Penn an Teller.......well, Teller....has nothing on you Sir.....this straight up magic...... Well done I say! Well done!
I was thoroughly impressed with the first straight cut you made, awesome job
You'll love using a plasma cutter...

I didn't even have to try one. I saw an everlast plasma cutter in a youtube video and said I needed one! LOL
Darn! Another project to build.
Probably should buy a plasma cutter first, though.
Great video.
Thanks,
John
Very sharp. Very good idea. Simple but very effective...
Nicely done, great look at this machine too which seems to be available at a very reasonable price.
todo esto es impresionante, lleno de técnicas y habilidades. Gracias!!
Ecellent performance, as always!
very cool , Great homemade setup works well for cheap money invested . I love it , Thumbs up !
Very nicely done!
fok yeah I'm gonna "click here" to see how the gears were made!! awesome video!
I liked the pliers that you used in the drill
what a great little machine! thanks for sharing
Nice invention, really liked you made it out of what you got 👍
I like it. Simple and functional
I can't wait to see what your making next 👍🏻
Nice work!
That is very handy. I like how you can start it and pretty much forget it until it finishes cutting. I will try this with my everlast plasma cutter thanks.

+Peter Gregory I bough the cutter so you don't have to. I can sell the gears at less cost than you can pay for the cutters to make your own.
Brilliant idea! As always, a pleasure to watch. What's not to like?
Sweet As it could Be!
I will try this with my powerplasma cutter. Thanks for the tips.
Ma sha Allah. Alhamdulillah. Lot of thanks.
Clever and quick.
Is it also possible to use a magnet instead of drilling a hole in the middle? Great video!
I did try that. The heat is not good for the magnet and not as firm. A better magnet may be OK.
Very nice boss
Yeah, super quick and dirty, positively filthy. Just reach into the scrap heap and pull out any old geared motor lying around there ;-)))
Thank you.
Cool idea. I've got a few ways of cutting circles with my everlast plasma cutter.
Not quichN'Dirty but Nice and Nifty !
Really worth copying ;-)) - thc for showing !
Use a coil to avoid center drill, magnets loss their properties above 70°C
On those straight cuts, are you dragging the tip along the guide or the material? I just got my plasma cutter and I thought you had to hold the tip up so it's not electrically contacting the material.
It's fine to drag the tip on the material. Once the cut starts you can move it away a few mm but it's not necessary.
Great, thanks. I was wondering about this since so many people seem to use metal straight edges and templates.
John Ridley some machines come with a drag tip. My Hobart is not one of them and it goes through electrodes and tips way faster if you drag it. Check your manual.
What you recommend how many amps are good enough for cutting 12mm gauge of sheet metal ?? SIR GEE
This machine is rated at 12mm max cut so full power would be suggested.
@@myfordboy will treasure the care thank you so very much SIR GEE
THANK YOU...for sharing.
Wonder if your plasma cutter has held up well? I was thinking of buying one.
Still working fine. It does not get used that often.
Nice. I should make myself on of these for my powerplasma cutter.
Dear MB, (D) as ever a top video. Brilliant work and very encouraging to us (me) amateurs 8). ps was wondering if you were going to fry up on the cut metal...
Alternatively you could drill a piece of bar stock with the plasma head diameter on one end and the center post diameter on the other, and manually cut a circle. Similar in concept to how you'd draw a circle with a compass.
+Jeremy Keller I tried this first but I found it difficult to move the torch at an even speed on a small diameter like this.
+myfordboy It seems the constant speed is the key to a great cut. Thank you for sharing.
+myfordboy your way will definitely make a cleaner cut! Also, ive used Masonite templates for all sorts of shapes, just need to factor in the offset between the plasma and the edge of the torch tip. The Masonite can be used for several pieces before getting too burned up. Thanks for sharing your inventions!
How many Amps and how psi using for plasma, and metal thickness
You need a 15amp supply. This model will cut 12mm steel. You need a high volume of air mine is 14 CFM.
Very nicely done. Can any motor be used for this as long as you run a VFD with it?
+🔥Ramsey Customs - turbocobra I have a nicer motor than the one used with an electronic speed control and nice gearbox. I used this first. It could be reduced in speed to what i needed but as soon as the torch was fired up the motor ran at full speed. Somehow the electronics in the plasma cutter interfered with the motor controller.

myfordboy ',
Great idea and execution.
How would you rate your plasma cutter? I've considered purchasing the same model for some time.

good work

EDIT. OH wait. It isn't galvanised, is it? LOL. X'D
TableWolfMusic it's not galvanised it's painted steel but the torch does not heat it up so no problem.
CNC set up for the plasma cutter next?
Easy but genious :-)
What's your thoughts on this machine and what thickness would you cut up to?
+Stephen Weir It's listed as cutting up to 25mm (model Cut 25)
I have tried it on 12mm and it cuts fine. For £140 including delivery i think it's excellent value.
+myfordboy I was looking at them myself and thought they were good value! I'm sure you'd get your money's worth before they'd give up the ghost

Hi Myfordboy a QQ: about air compressor you use for plasma, how many liters/min is it able to provide ?
thanks
Mine is 14 CFM (396 ltr )and has a 90lt tank.
wonder if you can plasma cut aluminum
+mtktm Yes you can cut all metals with it.
+Mentorcase You can even cut wood, glass, plastics and etc. if you place a metal sheet on top. Will need to experiment to get good results. Heat glass first or it will crack, wood scorches and plastic melts if too slow. Doesn't work real well for everything but sure is fun to try.
Mike (o\!/o)
good trick
so clever!
Small side to side movement from right to left and you won´t get the starting notch to the starting position.
Great,is that pvc pipe?
No, steel
How you did that gear cutting??
Like this ua-cam.com/video/5mTJMQAB-_Q/v-deo.html
very cool
Neat idea.
Hi.... how you make the gears, .......? thats the hard part.......!
The gears are made like this ua-cam.com/video/mreLx-t1HUA/v-deo.html
Awesome!
Should use a speaker magnet instead of drilling a hole
You need to aim the plasma in the direction you are cutting not dragging like your first cut.
genius
Good job but You Did not show as how to make the gears? ☺️
+عبدالله بو تركيThere is a link to the gear cutting in the description under the video.
+myfordboy Thank you sire
What a neat Idea Bravo!!
What is the motor from - I would guess it's a windshield wiper motor but looks
really skookum (Canadian word for robust lol). What type of vehicle would it be from?
Also, as I was watching I had an idea that the threaded rod could be replace with
a high power magnet.
Thanks again David - just your average excellent video!
Rod
+Newmachinist The motor is a mains AC ( 240 volt) motor but as it is series wound it works also on DC . I tried a magnet first but when cutting smaller discs the heat from the torch shattered the magnet.
Just think. If you made your setup into a pantograph, you could have cut the teeth for the gears too!
BRILL !!
👏👏👏👏 Excelent, very very bueno jajaja
This method doesnt seem quick, or dirty, does leave a clean cut though.
Genius
How cant i get this inverter?
Mine came from Ebay a few years ago but I don't see it for sale now.
Your circle cutting device is genius, so what lol.
Klasse.
Proper old fashioned 1970s vintage Workmate. Not like the cheap cr@p they make now.
Yes I've had this from new, I must be old!
super machine,,,,,
ANILSINGHRAJPUT. I KNOW VERY WELL PLASMA CUTTING. THANKS GANDHINAGAR GUJARAT. ALL TYPES OF CUTTING-EDGE & ANGLE.
yes if not too much precise measurment :-)
