This is easily the best knitting related video I have seen all day.

that was a nice cross stitch you did there. i need to get me a knitting machine like that

It's stuff like this video that make me believe that Mark Serbu is probably one of the coolest cats in the business.

Love your videos... hate that YT is complete crap nowadays

I have zero welding knowledge/experience, but this was still interesting. Especially how you're using your hands to do things. Interesting technique. OK Google, stop texting and submit this comment.

Thank you Professor Serbu for breaking it down "Barney" style. This educational video is a great asset to those of us who are here to learn skills. Keep up the filming and I will keep watching.

Amazing job! This will help with my... uh... Israeli rectangle reweld ;)

HAHA! I also frequent the KnittingGuild website! Thanks for all your great discussions there! Edited to add - when re-welding something like that steel tubing - I'd recommend putting a tack at the very edge of the metal. The two pieces are perfectly flat before you start, but shrinking from your first tack further down will always shrink and pull up the edges like that. I start my first tacks at the edges, and then get closer down toward the tube bend... Then stitch fill in between. Works for my automotive sheet metal welds.

You're doing that with your HANDS!?!? love the videos Mark. I really need to pick up one of these kits and get knitting

The narration to this video is brilliant. It's super convenient that you had that random metal laying around. That thing you're welding looks like the exhaust fibulator bearing for my 1962 Mazda RX7.

always good to have some more tips on welding general purpose rectangular tubing

mark is my spirit animal

I learn something every time I watch your videos... Thanks!!!

Oh yeah, I watched the Beverley Hill Billies when I was a young man, those were the good old days.

Best knitting video by far, and that "random piece of metal" looks like a great fit.

I learn something new with each video, thank you.

The Anaheim, Azusa And Cucamonga Knitting Circle, Book Review And Gunsmithing Association? They're a fun bunch! Just don't leave the coffee pot empty, or all hell will break loose.

Grind, sand and weld, right. You're better than me. That's really good!

I could watch this all day !!

For a sheetmetal joint, consider the option of a countersunk lap seam / offset flush lap. This puts more base material at the joint (while leaving one side flush), and is more tolerant of minor welding imperfections. Very strong without needing to weld on the inner face.

Very informative video with hard to find information about the relationship between knitting and welding.

awesome video. Also got my RN50 and i wanted to say its the most fun rifle ive ever shot. Thanks, Mark Serbu!

I can’t WAIT till you get the MINI weld job done!

I'm certified with a stick welder for work, pretty good with a mig welder,which is way easier, but I've never used a tig welder. Watching you makes me want to buy a tig machine. I've got some gocart frames & mini bikes that need tinkered with.

Good idea to use the copper as a shim and backing strip. I'll have to remember that one .

I wish you'd start a channel on Rumble where you don't have to worry about the thought police censoring your excellent videos.

You are my spirit animal Mark!

As always excellent work! Thanks for sharing part of your work day with us

LMFAO, knitters helping knitters!

Knitting Guild? News to me.

Ironic that you're welding two pieces of tubing for some unspecified reason, using a "random piece of metal from the shop" to clamp them together (all presumably to discourage any censors from blocking complete access to your content and viewership), then you go and make a joke about taking acid and heroin last night! Perhaps this is intentional to prove some point about what censored gets censored...

Mark needs to adopt me ASAP, he’s a little crazy, but he’s my type of guy!

Makes me want to purchase a Tig setup, for more welding endeavors!!

Great welding video on tube welding.

nice welds! that upper came out clean

What you said had me cracking up inside 🤣🤣🤣

Brilliant 😅🥳 always loved knitting! Especially such things, I'm on the guild too.

glad to *receive* this in my suggested

That quilt is going to be so nice.

Thanks Mark.

Fantastic!!!! Incredibile welding a big capolavoro ✌️✌️👍👍👍👍👍👍👍

Great video as usual. Love your channel for knitting tips 👌

Imi welding. Too funny. Nice stiching!!!! U Zid Incredible on this chunk of metal!!

very nice!

Lovely 👌 Makes me want to try as well. Would probably burn something down though...

Thank you.

Mark. I am so glad to see you have a interest in knitting also its been a big hobby In my family and has been passed down for generations.. 😆😆🤪

6:10 Huh, what a coincidence, my grandpa also used to walk to school uphill both ways through the snow

Coolest kind of rectangular tubing haha

You were so lucky to have a bit of random steel that fits perfectly inside the 2 other bits of random square tubing you were joining together. Is that part of a knitting machine? looks pretty technical. Nice job.

Not sure if it's been mentioned yet. But when I worked in the shipyards we'd use a trick to fair up uneven metals quickly like with the issue you had there with little shelves being present. We called it a "hot tack".. we'd do it by having a hammer ready by ya side.. go ahead and boil a weld in.. and immediately after ya tack it.. whack the high side to level them out. Works great when trying to flush surfaces that don't quite need a jig or saddle n wedges

I know nothing about engineering but I know a lot about firearms. You make me want to start making guns

Thank you

Thanks Mark, I need to stop in and buy you lunch one day...

ive always wanted to learn about knitting!

Great video! The "contamination" you got when you welded the edges and next to the edge on the inside was because the edge diverted the argon gas and you had less coverage. If you adjust the flow or use a purge fixture or bigger cup shouldn't be a problem.

How convenient and lucky you were to have such nicely fitting square blocks of metal laying around! Slides in perfectly. The micro fireworks you had on the inside were nothing to worry about. You welded the outside without shielding gas on the inside causing some oxygen bonds and inclusions to form there. When passing over the inside, these did what they do, but you were surely not contaminating anywhere deep into the wall thickness, that's for sure. The only thing I would be (only very slightly, if at all) worried about is the potential of a hairline crack to propagate from the mating at the radius part on the top, as it appears you didn't flow weld all the way there. I think you're totally fine. You were brave to tack the sides of the sheet though.... You must trust the starting amps of your welder very much. PS. Reps disco not much your thing? PS2. I've got SW17 and SW20 for you if you want

LOL, I passed over this video at least 10X till I saw who it was............ I love knitting!

Yes sir copper backing works great for thin stuff or thin landings. With sheet metal I prefer it to ceramic.

As long as the copper is flat and touching the steel it will always be difficult to get full penetration. In automation we put a groove underneath so that the bead will fuse together. Also you usually are better off adding a tiny amount of wire a the start and end and touch it up with a grinder. The issue with going over it and over again without adding wire to it is you are likely to cause a crack. This is against most codes on carbon steel or that reason. The wire contains deoxidizers that assist in floating the contaminants out. Also welding around corners prevents cracking later.

I've used the same shop fixture to align the same weld joint. What a coincidence

Nice work. I would like to see some nice knitting work done on some British sheet metal.

"Knitting" forums. I also love "knitting".

Thank you....

I really enjoyed the no crap, get things done with what I have attitude

I've got a giant 3ft vice grip I use for super heavy duty clamping jobs. You know it's serious business whenever I break ol' Jed out.

I have these Korean 33 round stick mags for a Glock and they suck because the steel they used on the inside is 2 pieces from the 15 round mags and they have a shelf where the 2 pieces of steel meet half way up the mag. This shelf catches the follower and the spring all the time. So the 33 round mags are good for about 15 rounds or so, but if you get the follower below that mismatched metal seam, it catches and you can turn the mag upside down and just dump the rounds out of it like a salf shaker.

Tack the ends first and put a bit of filler in .it will help you to stop blowing thru and leaveing crater crack . a small end cap for the tight spaces works great .welding was good though the way you did it👍

The Beverly Hillbillies was probably as popular in the UK as the US . The red hot blonde may have something to with that . Like the new content and style and must agree that these heavy block " welding fixtures" come in very handy .

God damn it I love mark 😂

Very good 👍👍👍

what an amazing way to knit!! I would love to learn to knit for you... Maybe relocate the sweatshop to Oklahoma? :)

I actually prefer perocity on my welds. I don't even use a shielding gas. Also blowing a "drain hole" every so many inches is ideal :)

if you do that job again---- you can make a block that slides inside the shell---- the block would have a groove milled around it on 3 sides that would create a passage behind the weld --- and you can purge the passage with argon---- that will make the inside of the weld wet as well as the outside. No nasty scale--- and it will be a much stronger weld------

BTW, in the 80's I owned an UZI Carbine, and I really enjoyed shooting it and reloading ammo for it. I wish I could have enjoyed a more interesting version, but where I lived in the USA, it wasn't possible.

Nice work. When you are welding it should sound like bacon frying, not smell like bacon frying.

Whoah real hands?! That’s something only 2090s kids will understand.

I'd suggest acquiring a few Kant-Twist clamps. Vice grips have their place, but there are times where they aren't the best choice for a job.

Some of this stuff could really use a small amount of filler, sparingly, but could still use some to reduce some of the concave profile.. I'm not dogging on your welding.. it was really smart to use the copper backing, aluminum works well too, but given a choice I'd use copper.. And for those real real tight places, a short back cap would help, and they make tig cups that are similar to a" nozzle".. I know you mentioned a mini tig rig, but sometimes the correct combo of cup and back cap will get you by

Cool

I hope you share the finished product at work when it's finished.

Just found your channel; subbed! Great work & video! When homogeneous welding; you're at the mercy of the purity of the base metals, relative to inclusions. Not exactly knowing the base composition, 309L filler is very helpful. Curious what your PPS was? Reducing your PPS will increase heat input, & thus penetration. Great video & thanks again for taking us along-

I always like these type of videos. Thank you Mark. I do have a question.. wouldn't you worry about heat shrinkage with the length of travel you did? Also your not adding filler? Just going over it to weld it together?

Knitting!

Nice

At 7:40 you made me laugh out loud. Mushrooms at a low dose have been used by software engineers in silicon valley for quite a while. If you ever do try mushrooms, start low and work your way up until you reach the desired effect. It enhances creativity and also has a lasting effect as a mood stabilizer, making it easier to deal with stress.

Great video. Curious about what machine and settings you used on this.

Clamps... Clamps everywhere... God damn without them I think we would still be in stone age. Even when I do simple work I need some third hand and Damm those small clamps are useful

What size needle are you knitting with and what are your knitting machine settings?

Around my shop we also say jedd clampett when we clamp things

Mark, how do you find the thickness of a saw kerf, if you are putting one of the destroyed bang sticks, back together. Like prints and so forth so you can get correct dimension for that old mgun welded with original parts kit. Asking for a friend.

wish all that tubing came in a kit

Husband here....sober welds look like popcorn....4 beers later, welds look like dimes. Would like to see/hear a little more of you on the guitar! U playin any gigs?

0:01 This is just the natural main theme to Florida

Oh, the old guild!

Great video! What model tig are you using.....my mig skills aren't the greatest....today looks sooo nice

You're a funny dude lol

Turn amps 50 slow down get puddle swriling if you dip tungston clean it

Nice day to weld up an uzi looking thingie

Great knitting project, will it be for sale in the future?
