Freshly roasted Columbian coffee and 2 minutes ago TwinStick uploaded. Always a good day.

[@areyouavinalaff]

Shake hands with danger music plays.

[@blakedismuke3656]

I prefer Colombian bam-bam.

[@jakedelaymustdie6665]

Standard stears for sure. Keep the old school look. Always look forward to Thursdays twinsticks!

[@jimdieseldawg3435]

Hey Mark 🙂 Ref. the wide front rims: that became a thing in Europe in the early ‘90s, theory being that wider tyres (385/65R22.5 super-single trailer tyres over here) run cooler and last longer. True to an extent but folks found that their truck rocked in and out of the highway truck ruts like a beagle after a scent. More stress on steering joints and kingpins too, mainly due to moving to a wheel offset that the geometry wasn’t designed for, and using trailer-pattern tyres rather than steer pattern. Now, most manufacturers offer them as a factory option with steer-pattern tyres, suitable offset and revised geometry but the fleets seem to have moved back to 295/80s or 315/80s instead. It’s down to personal choice but I reckon the Duke will look better on period skinny 24s 🙂

[@MegaEaglelover]

Glad to see Iron Duke back on YT again. Ready for continued adventures with this Rig 🤘🏼🤠🤘🏼🤠

[@Chr.U.Cas1622]

Dear Mark P. 👍👌👏 Congrats for having such a good guardian angel! I checked out the channel you recommended. The first but not last video I watched was about the welding table bargain. Best regards, luck and health in particular.

[@MF-rn5os]

Thursday lunch with a video of iron duke. Best lunch break this week

[@trevorbarlow3911]

The snowman truck is absolutely awesome it’s a real privilege to watch the build I’m looking forward to seeing the iron duke take shape well done

[@johanlarsson4996]

Go with the standard, I love the old school look!

[@oregonfordguy9812]

we staring at snow this morning. 8" Portland oregon. welcome in winter #3. what better to do than watch twin stick in the snow.

[@DieselDoc78]

Personally I'd go with the simple 11R-24.5 tires on the standard rims. The reason being, with as long as it is once she's stretched, you're going to need all the turning radius you can get. With wider tires, I'd assume you'd have to adjust the steering locks to keep from rubbing the Pitman arm and other steering components, etc. If you do deviate from an 11R-24.5, I wouldn't go much past a 315 series tire. Just my .02

[@dennissmith460]

Started driving in the mid 80s, and a lot of the trucks I drove were from the late 60s. Some had front brakes, some didn't. The ones with, had limiting switches up on the dash, with slippery and dry settings. We were told to leave them on dry. Not to mess with them. I believe front brakes were required in the US around 1970, give or take.

[@Stuka616]

I tought that i would not be interrested in the cab over project, since im surronded by cab overs in the frozen ass tundra some would call Finland, but damn.. I might have to become a patreon after all 😁 Cheers Mark!

[@ernieferrington3358]

Hey mate. You can buy a Teflon plate that slides into your spring hangers to prevent the spring chopping out your hangers.

[@Ezrider359]

aluminum is a great material,..... just not for truck frames. 300" on a cabover is going to be long. old red is 280" look forward to part 2

[@spottedhoss1920]

Mornin Mark, The Iron duke is slowly coming together and it's looking good. I have never worked on aluminum frames so I am just taking your word for everything, but I do see what people have always told me about the corrosion and yes it looks bad, but I'm sure you will get it done. Have a great week my friend and as always say hello to Mrs. Twin stix for us.

[@uliwehner]

as he is cutting the frame in 2...

[@shamaYahu8635]

Hi do you know the name of the song playing at 5:25 ?

[@brandondrescher2182]

Another great episode Mark! Crazy how far the Duke has already come. Keep up the great work!

[@jstangley4409]

Hey Mark... enjoyed the iron Duke project today...good effort Sir.

[@psg6314]

The k 100 I drove had a 280 in wheel base and road good with the shorter turnaround it was a 85 model and great video keep up the good work God bless from GA and stay safe

[@johnnyholland8765]

Hey a fellow Georgian! I am in middle Ga. just south of Macon...

[@surfranger1]

Australian K108 aerodyne and we made and fitted stainless steel exhaust in 6inch from the turbos to the exhaust stacks, with custom made stainless steel shrouds .....and air intakes is twin 6 inch with donaldson aircleaners with stainless steel hats, all mounted on gantry. All the stainless is mirror finish 😁😁😁

[@truckercowboyrobertharris6787]

Another great Thursday and another Twinstick Garage video of Iron Duke.

[@hammers1518]

George Kennedy in the background saying "come on Lucille". Oh, he wasn't talking about you taking those bolts off!!!! lol

[@DavidMartin-tp2in]

Enjoyed watching this video on the Iron Duke, hope you continue to post random videos of it's pro.

[@vernfrederick5025]

I love twin stick garage look forward to a new video to see what Mark has going on ,thank you again Mark love you program I’m a retired trucker and miss being behind the wheel

[@bradwarner8933]

Hello Mark, I appreciate all your hard work and can do spirit! I got tired just watching you. A lot of folks don’t realize how tough it is. You have awesome trucks!

[@backpi]

Peg would be really proud of you safety glasses headphones and gloves. ☺

[@379insk]

Go with the 8" flappers! I have 7" flappers on my 379 and i love them! My truck is a work truck that sits outside and rhe keep out the moisture!

[@Jerremy10169]

Whenever I’ve done a frame extension I’ve always done a straight cut and weld. Then add a peace of U beam to strengthen the frame. Always go back and forth top to bottom until you meet in the middle distributes the heat better

[@neteaadrian1654]

Thank you for the video Mark, like allways you are doing a great job and i like watching your videos. Wish you all the best.

[@rickjanzen-qb1qt]

Looking great, go with the wide ones up front, and keep 'em coming, the update episodes. Abe

[@caveone-365]

Yes! Some Argon 'backpurged' pie cuts to complete the radiuses on your stacks would be awesome 👍 built stainless exhausts/ charge piping before using the same method and it works well. There are even sites out there that sell pre cut pie cut sections. You can easily make your own with a chop saw, but they sell them pre cut now. I'm sure for the 8" piping you'd have to make your own, but it's easy enough. Usually I chop up some sections with the chop saw, it takes a little while to clean them all up/ deburring/ chamfering the edges to get them ready to weld, especially being such large diameter piping. Usually what I do to make my own pie cuts, is set my chop saw to around 15 degrees and just cut away about a dozen pieces to start. You'll probably need three times that amount minimum for this type of project if you're going to do the complete exhaust that way, probably more than that honestly. I'd buy a couple 180, and 45 degree mandrel stainless pieces, and or course your flex joints and some v-band clamps/ rings unless he's really going to do it all in pie cuts, in which case you'd need nothing but a straight 8" section and some reducers obviously. It's definitely doable with nothing but a straight section and a whole ton of pie cuts but it'll be a shitload of welding. Not saying it can't be done, just pretty labor intensive. He'll need quite a bit of Argon, for the associated back purging, as well as some aluminum foil/ tape because I doubt that anyone has the 8" pipe plugs made up to hold the hose for the Argon/ shielding inside the pipe. He'll definitely be using a lot of shielding gas/ filler rod too. I'd have quite a few tanks ready to go, especially since it's 8" piping. I'd love to see what you end up doing here. Deboss Garages' K100 build if you've never seen it, has dual exhaust stacks/ dual intake 'stacks' as well all running up the back of the cab and it looks great IMO. I like the look of it being 'balanced' and 'even.' I'm sure it slightly helps performance too, since forced induction wants the exhaust as short/ large as possible figuratively speaking and there is no need for back pressure in a boosted application.

[@jaxithfox]

Wide/heavy steers really are a good look on a truck. Especially with a cabover where the actual width of the tire is more visible.

[@seanmesaehable]

do the wide beefy look!! its different that what everyone else is doing with super low trucks. i love the tall rubber and tall trucks , like the logging tridrives you see up in canada. 425 steers and 11r24.4 drives

[@Tylerssouthernliving]

Definitely wider wheels and tires for the front of the ole Duke!

[@mikestobbe4274]

Mike have over has an aluminum frames as well California truck mint and I wanna stretch it I’m so glad you’re doing this I want to see it

[@nelsonhernandez2513]

Mark I learned in shop class in high school it helps to sometimes tighten then loosen to free bolts

[@1one3_Racing]

An old farmer once said to me "Theres only 2 tools designed to remove nuts. But there's hundreds of tools for removing stuck nuts. So if it doesn't break free, you don't have the right tool" Usually he would say this while lighting the oxy torch. But it was his second word of wisdom that stuck with me. "A bolt is cheaper than a socket. Just cut it before you break something!"

[@gwill983]

“Shake hands with danger!” Awesome 👍

[@robertquast9684]

As long as you have the access you could put aluminum cross members in. Our 377 had them originally. I am sure a salvage yard would have them. You could eliminate some of the steel to aluminum corrosion.

[@w.neddusharm6432]

Hey Mark when you get that frame cut off and all cleaned up and the bracelet back in there you should take the other brace off the back end of it and do the same thing you're going to have a nice frame when you get done

[@tomshumaker7370]

You are a better man than me Mark. I would of stopped to watch "Lucille" wash that car on COOL HAND LUKE running on the TV in the background. LOL

[@TheRestorationShack]

Seinfeld nailed it 😂 was so in to the video, wasn’t until I noticed only 2 minutes left, it dawned on me. Great video and always entertaining Mark. Think it’s time for me to Patreon up so I can watch more. Can’t wait for this and the plans for LBL this spring. Remember- if you bought it, a trucker brought it!

[@josh351]

We put 8” stainless pipes on an old freightliner classic we just built. It has pie cuts for the bend going under the cab, the welds are polished and I think it looks better way

[@KingTI192]

I can't wait to see The Iron Duke when she's all finished up. You put some really good work into these Ol Girls. It's all worth it. Once your driving down the road. Plus it's like a hobby. Fixing these old trucks up. They just don't make them like they use too

[@aleklacinaal]

"We'll have a 300 inch Duke" I usually have one of those after I eat a footlong from subway 😂

[@1one3_Racing]

We just weld packers into the worn out leaf hangers. They hold long enough if you weld them good.

[@louisroman7134]

Thanks for sharing.

[@AndrewSandilands-tk6st]

Great to see the Iron Duke on KZbin again, I hope the continuation of this comes on too 🤞 lol. I was just wondering, have you been able to fire the old girl up since fitting the Jake heads?

[@TwinStix]

Coming soon 😎

[@dakotagraham2746]

Love your videos man the only think I could add respectfully is to tell us what movie your watching love those oldies or make a list of your top old movies

[@billylizzatruckingchannelandga]

Twin sticks Garage Love That Iron Duke My Friend Had a Truck That Looked like Iron duke Keep up the good 👍 work Billy Lizza Uniontown pa USA

[@majobis]

I would consider the old GMC Cracker box cabovers with very short cabover trucks. I have seen a 1959 version in my area that is a barn find with air-ride and I am told that is a rare option on those types of trucks back then.

[@nfprojectshop]

Yes.... You got to go with the rain caps! They're awesome!

[@gordonbrown6793]

Just a comment on your blowtorch use: I was taught that the tip of the inner lighter blue flame cone is the hottest point and always aim to have that bit of the flame on the work.

[@areyouavinalaff]

That blow torch is never going to put any significant heat into metal anyway, it's only good for stripping paint.

[@conwayconway2177]

Ohhhhhh yeahhhhh!!I love Mark's madness and weekly shenanigans c'mon haaa haaah...God bless ✝️🇨🇦❤️🇺🇸

[@theillinoiscountryboy5403]

I love the wider front tires

[@soonerlegendspodcast]

Mark please keep the standard width rims. Duke would still look sharp

[@fazerainbow5674]

awsome video mark iron duke is comeing along really good for sure thumbs up and shared

[@jandcco]

We have a W900 that is 313" another W9 at 307 and a T600 at 300" and a T800 288" we see long wheel base all the time 😁

[@Mclint9171]

Old cab over, yes go with the flappers on the pipes. Gives it that old school look

[@steve_does]

Zipper ruptures kill! Be safe Mark!

[@bwlyon]

It would have been nice if whoever cut the air ride frame module to have cut another 2-3 foot forward. That would have given you a much better place to make the splice. If you plan to pull a loaded trailer, talk to a reputable frame shop that does frame stretches about how to properly reinforce the frame. The last thing you want is to weld the frame together only to have it fail on the road. 😮

[@mikeCAT-D813A]

Hey Mark! Got the ol Pete all chained up eh🤟

[@Johnditit]

Hey Mark, I'm worried about the location where you are splicing the rear cutoff. Having a splice where your hangers are located seems pretty risky. That area is going to be exposed to high stress and I'm not sure I would want a welded seam in that location. After the hangers and crossmember supports are added back a crack could go unseen for quite some time and allow catastrophic failure in the future. Most cut offs I see people using are cut off with a couple feet of frame rail ahead of the rolling stock. Might consider shortening this up a little and move that splice back a ways or just swap the suspension to your existing frame. I have a feeling I may already be too late on this, but the choice is yours. Love the project.

[@379insk]

Yeah...i have seen lots of frame mods includinf one on one of my trucks but never at that location.

[@mattstewart5712]

Company I used to work for had an early 80s Ford that had an air switch for wet or dry roads that would shut the air supply off to the steer brakes

[@regal105]

Petition to get this man an oxy acetylene torch!

[@josephpolanco4226]

man go with the wider front tires its the look. Just look right. Really enjoy your content keep up the great work.

[@Ktgsvtrdg66]

They are expensive but a pair of 455 steers would look awesome on iron Duke! Thats what I have right now and honestly steering ain't too bad. They are a more dangerous blowout tire though.

[@richardroden6773]

Hey Mark. Really look forward to your postings every week. Watch on You Tube so haven't been keeping up on the cab over. Not keen on the extension you're going for. I know you have a vision for what you want the truck to be, but I think it detracts from what the truck was meant to be. Just an opinion. Hope you are happy with the results. Thanks again for the great videos.

[@ChrisBrown-vx3sb]

You content is so good. Taking too long to get to 500k subscribers. Keep up the good content. From Jamaica 🇯🇲

[@charlieromeoh]

Love the cabover content. Looking forward to more !

[@michaelschmidtke1525]

Argon is used to back purge the welds. I believe a chemical reaction called sugaring happens inside the pipe. It’s a black particulate that hangs onto the inside of the pipe, and think pre turbo that stuff can flake off and go through the motor, not good, hence back purging. So it’s not needed on the exhaust side but o totally agree in doing it because it would look damn good. If you wanna go crazy maybe prove our some titanium in your dimensions and when that gets warm you’ll get that nice purple blue pipe like Zondas have!!!! That would be a show stopper!!

[@charleslowe4589]

CRC makes a glorious spray called free all i believe without running to my toolbox to double check for steel bolts in aluminum, i use it with good results, maybe give it a try.

[@troypatton7290]

i like the wide tires and rims for the front mark, i noticed james pretty has a set on his kenworth cabover

[@kevinjones2667]

Mr. Mark. Nothing beats beating on something that doesn't want to come apart lol ❤ from pnw oregon

[@zukowski2023]

Mark, you gotta embrace the wonderful world of oxy-acetylene. Heating up the aluminum around the bolts will break most of the corrosion it will also cause the penetrant to "wick" into the bolt holes due to the heat, and make breaking bolts free so much easier. I get it you enjoy doing it the hard way, but there's a bunch of us screaming at our monitors telling you to heat it up Laddy!

[@baileylogan8369]

Hey mate those welds are tig welds I’m sure you probably know this already but just in case you didn’t, now you do. In saying that it would be pretty cool to !

[@TwinStix]

Yeah I just said it wrong 🤦‍♂️

[@cedricjones5696]

I have been trying to talk my friend into letting me build a set of stainless steel stacks for his truck. I personally hate chrome and I believe stainless is the way to go since it can be polished again and again. I tig weld tons of stainless headers and turbo systems and many of my customers ask for pie cut exhaust. It a lot of work just for looks.

[@theowiththeo]

Great project!

[@chosenone101]

Looking good with the cabover!

[@Collin_Calaway]

Would be sweet to make it a tri drive with those extra axles. It would look real good with 3 drive axles and wide steer tires.

[@jackmott5533]

250 WB was long back in the day for a cabover. I believe that would be the perfect length!!😎

[@kylederry5031]

Would you believe they still show SHAKE HANDS WITH DANGER in college? I graduated in 2010 and I'll never forget, I like gory movies but that one hit home a little more

[@alanstrathern]

Agree with your comment about don't trust your jack but please use axle stands. Don't use wooden blocks. I work in emergency services and recently had to see someone die under a truck just like this as the weight transferred onto the blocks and they gave out when the jack failed. Died instantly and the sight was horrific. The wood splintered with the weight and literally exploded due to the transfer of weight.

[@yosvi85]

I think you should've done the same thing as Rich from Deboss Garage and gotten a hole steal frame then transfer the cab and power train on to it.. either way, keep up the good work!

[@MegaEaglelover]

Great movie 🎥 in the background, “Cool Hand Luke” “What we have here is a Failure to Communicate.” Which is what those bolts are sayin to U LMAO 😂

[@ryderzea9614]

Definitely go with the wide set up in the front!

[@christophermgwadira4400]

It is another Thursday!

[@rosshall641]

Yeah steel aluminum are not compatible but it will come together Mark 👍👍

[@jon89tsupra]

Save the wide wheels for the heavy boys. I like the look of the regular wheels.

[@davidcatlette9697]

Hey Mark look into a toque multiplier ! Some of them work both ways 😳 and a 16 lb sledgehammer ! Less hits is a good thing ! And I have a old torch set ! VICTOR body and cutting head ! Will go too my local post office too see how much it would cost too mail it too you ?

[@fionakeller2176]

After watching high ballin I hope duke gets the pa speakers since it’s not an 892

[@surfranger1]

i have 2008 K108 aerodyne, is fitted with alcoa supersingles on the steer , so much better ride and steering Australian K108

[@bigpaulrc3531]

If you put super single tyre's on front end it can wair your king pin but looks cool

[@tracymankey9314]

You are a good mechanic looking good ❤

[@marysoldeeley2218]

Yikes, that IS terrifying, glad you were a distance from that tire when it went. Never do that twice Eh. Great episode otherwise! That truck is coming along great!

[@wesleycurry9118]

I think it would look good with the wider rim an tires. Like Bruce Wilsons blue collar cabover

[@ajwaever]

Little by little used to be a farm truck and I know on the farm I used to work on in Wisconsin we hulled way over the legal limit not on purpose we just didn't have any scales near us

[@nelsonhernandez2513]

You need a flame less induction heater there’s one on Amazon for $179.99 makes bolts glow in less than a minute

[@4spdlife857]

I watched a guy hang a 10mm wrench off of the counter weight of a 2-2 1/2 inch flap and it perfectly balanced it didn't clap and even after full throttle they still closed on there own when he shut it off
