Tim, very well done sir! I would advise you not to use abrasives for mild steel, only for stainless steel (inox), or if you don't have them use new, never used before abrasives for mild steel. You risk the chance for particles of mild steel rusting on the SS. I work into metal construction and fabrication so i was taught this from the very beginning. Also, use a couple of different flap discs with different grit, this gives high polish, which prevents rust and looks a lot nicer. You can also polish each piece you cut in opposite direction to get the looks of a football lawn, or shades. All the best in your future work. bye bye
Nice work! Maybe you have to passivate the parts when they are used outdoors. Stainless steel is stainless, when the surface is treated correctly by etching (pickling), especially after grinding and welding (or plasma cutting).
It's oxy acetylene that struggles to cut stainless. The no rust properties of stainless make it such a fabulous sign & letter material. It will polish to mirror like finish with a mop. I don't have a plasma cutter, but might some day try & cut with my Tig torch, although the need to use Argon at high pressure makes me balk given the cost of Argon gas, kind of wonder if I could substitute compressed air for the Argon to make a poor man's plasma cutter. Thanks for sharing!
Often times, stainless steel has Chromium, Molybdenum, and Titanium added to it which gives it the stainless/rustless properties.... maybe this is what causes or partly causes all or some of the burrs on the backside where the cnc blew out the metal
I second Michael's notion that stainless/Inox fumes are quite toxic. Hexavalent chromium is very nasty stuff. Respirator and good ventilation are essential. Not just plasma, the same applies to welding, but not everyone is aware of the risk.
Yep. I have a simple dust mask respirator that also cleans out welding fumes. The fume filtres aren't much more than regular dust ones (and also handle dust) so there's no good reason to not have it. You only have one set of lungs.
I made a ducks nest for my forge at work by cutting 3/8” hastaloy stainless with their plasma cutter, I took it home one piece at a time and welded it up with incolnel rod. I bet it weighs 75 pounds and no doubt in my mind it will still be around 1000 years from now if nobody turns it in for scrap and it gets melted.
The fumes and dust are bad for you due to the chromium in stainless steel. Make sure you wear a respirator with the appropriate filter or have good extraction. I work with lasercutting professionally. Nitrogen at 14 bar is used to blow the dross away when cutting 3mm stainless steel. I don't know if cranking up the air on the plasma will help any. Although I have a plasma cutter (from R-Tech) I very rarely use it.
It's been mentioned already, but using the same abrasives on stainless as MS has an annoyingly high chance of contaminating the stainless and leading to rust. Most metal shops will designate abrasives, wire wheels, brushes and belts for stainless only and will keep them in a sealed plastic tub. Though I don't mean to be a bummer, the shapes look really nice.
Good to see this worked. I am curious, what is the grade of stainless steel? Some grades can rust due to having low amounts of e.g., chromium. It sounds like the dross work hardened. The end result sign looks very good. Dave.
It's a nice smooth cutting line on that machine. I would be laboriously trying to use a jigsaw with a hacksaw blade!! How do you direct the cutting motion?? By computer?? Or are you working on a template that transfers to your sheet of SS?? The letters look great. Had to laugh, did the studio ask you "Oh, just come up with a catchy phrase and we'll put it on the sign"??
That's the wonderful thing about CNC machines - they cut things out perfectly, because they are controlled by a computer. I just have to draw what I want on the computer and the rest is (usually) easy..
👍👌👏 Very well done! Definitely more work but looks great. I don't know the phrase " Don't eat Hamsters". Does it mean anything special or is it just a suggestion = better eat Guinea pigs cause they are a bit bigger!? :-) ;-) Thanks a lot for making taping editing uploading and sharing. Best regards luck and health.
I'm not an metal expert but from the time I've looked into building stuff out of stainless steel I remember beeing warned against using tools that are either made out of normal steel or have been used to machine normal steel. It seems terrible things can happen if one does (but I don't know what). Even for my stainless steel screws used to build my beehives they wanted me to buy a stainless steel screwdriver (I didn't - lets see whether the screws will become zombie screws at halloween now).
I you use abrasives and files that have previously been used on mild steel, you can embed tiny particles of mild steel in the stainless and it will rust.
You need more amps there. I cut massive ammounts of steel, mild, hardox, manganese and various stainless steels (both acid and heat resistant) from 0.5mm up to 30mm (more than 1000 tons per year). I use Hypertherm 125 amp machine and screw air compressor with dryer on 6x2m table with fumes extraction (check my channel for videos). For 2mm you need 45 amps in order to get better cut, edges will look much better. Also pay atention to cutting speed, too much and cut looks as a metal file, all serrated, to low and it burns the material. Not all stainless steels react the same to plasma cutter so be ready to experiment. Also, be very careful with the fumes, they are extremely toxic due to chrome.
Maybe the reason why you are getting loads of dross is that your pierce height needs to be 3.8mm gap, working height 2.5mm, use nitrogen gas, cut speed of 3935mm/min for 2mm stainless, 97 Arc volts using a 45 amp Plasma cutter. You can go search out a pdf online searching plasma cut charts.
Yeah it's with everything you get close enough & it will do it, just remember if you are normally setting a low amp for 2mm steel then the difference for stainless is higher amps, only marginally faster cutting, you could increase your air pressure then you can fool around with the pressure up to about 75 - 80 psi on test cuts to see if the dross is removed better.
You could try some oxygen free nitrogen instead of an air supply with stainless and aluminium plasma cutting. You mention that you are using 3 driers on the air supply, are these dessicant types? Normally high tip wear rate is moisture in the airlines. Possibly try a refrigeration type drier with a fresh dessicant core in series .
Dear Sandra if you end up reading this comment which I hope you do there is a pony charity called putting in the magic that is in with a possibility of being kicked of the land they use to rehabilitate the ponies on. and the lady who runs it is in need of ideas how to raise money any bright ideas maybe? they would be really appreciated if not that's ok I just thought seen as how you were able to get money for your hairy Henry project you might have some suggestions
Hi Wolf Girl, sorry for the very late reply...As you know we did a gofundme campaign which was a great success. It helped that we have a lot of followers on youtube and so were able reach people beyond facebook. But this sort of funding campaign is definitely worth a try, but I am not sure would it ever raise bigger amounts of money... What about an open day with pony rides and asking people to donate on the day? Or a flag/collection day - as a charity they should be able to organise that, an option that isn't open to me as a social entrepreneur...Wishing them all the best and that things will work out for them somehow!!! Cheers, Sandra
I almost lost a finger clamping my angle grinder into a vice like that using a wire wheel. Wheel grabbed the steel and slammed my finger into the wheel.. Not nice I can tell you.

Thanks very much - I have a lot to learn!
@Wolf And will it rust at the edge where plasma have cut it ?.
Satisfying to watch that plasma cutter. And I almost choked on my water from laughing at the last message, lol
Looks like you had a lot of fun with it at the end. That shiny finish is beautiful.
Wise words in the end, great job in the beginning :D Interesting info.
Isn’t cutting stainless with plasma or any hot method dangerous as far as fumes such as hexavalent chromium?
Giant fridge magnet letters!!! :D ... beautiful work, Tim. :)
"SNOTS NOT HOT" *spits coffee*
"96 THIN AUNTS" *snorts coffee*
Thanks Tim! 🤣
check out "this old tony" if you like spitting and snorting coffee
I'd prefer "69 Thin Aunts" lol
You are good at engineering machines to make useful items.
Nice work! Maybe you have to passivate the parts when they are used outdoors. Stainless steel is stainless, when the surface is treated correctly by etching (pickling), especially after grinding and welding (or plasma cutting).
Amazing that a small enterprise / hobbyist can get kit like that.
It really is!
Sage advice indeed.
Luv ya Tim, you are a wee ray of reality
Aw, shucks : - )
Very interesting, and the end gave me a good laugh! I hope you have a lovely day!

U need to use argon instead compressed air if you want to get rid of sugaring
That is really cool.

Tim you should make a Linisher and do a video about it. I bet you could cut the parts for the frame on your cnc!
that's another tool I'd like to have..

If I had lots to do I would investigate more, but it's good to know that my set up will cut fine - just needs more cleaning
Nice
If you turn the pressure up on the plasma cutter will it not blow the slag off better?
It doesn't work that way, unfortunately.
@@WayOutWestx2 then you either need more amps or to cut more slowly.

Dave.
Most common grade is 304 which is quite rust resistant. 316 is used when it needs to be acid resistant.
Sorry - I don't know the grade.
Looks good Tim. Like the dont eat hamsters!

Other wordly. Who could possibly eat a hamster ? Nobody subscribed to this channel , I hope.
Do you wear welding goggles to watch the cutter, or is it not as bright as a welder?
I do wear goggles, though apparently dark glasses would do. (Not certain that's true.)
