Building a recumbent tricycle frame part 2

Second of two parts showing the cutting out, notching, jigging, brazing and TIG welding vs MIG welding processes involved in the construction of a recumbent tricycle frame. For the sake of brevity only key examples are shown. The music is from "My Favourite Guitar" by George Golla.

Expensive but worth the price cause the enjoyment one gets by riding those trikes is beyond words.

[@jaks1312]

Came for TIG welding, stayed for Chega de Saudade, my favourite brazilian composition

[@dukedurell]

High quality work there !

[@MrJohn1966elliott]

Hey Dude ! You are very good welding ! High Quality ! I might be to buy Recumbent Trike, as soon.

[@ThePsicojose]

Awesome video, and great job. Thanks

[@genesioapretto5077]

Nice man! Professeonal made👍😉

[@darrco973]

i love your job !

[@noleggios]

Un bravo artigiano, ne restano pochi.

nice welding tutorial!

[@888mrshoe]

beautiful

[@rongpockle]

It depends how non continuos. The critical thing is not to overheat the cro mo. With thin walled tube and constant arc the weld is too cold at the start and too hot at the end if you get it just right in the middle. This technique gives a high degree of control over temperature and penetration by manual variation of stitch and gap time but you must always be careful to blend one stitch into the next. Use a hotter setting than you would for a continuous weld on the same material.

Parabens linda musica...trilha maravilhosa

[@Edwerdman]

Cool bossa nova music !

[@alexruocco6587]

the song is really nice! brazilian ReB

[@nurlanrayev8267]

Высший пилотаж.

[@rongpockle]

@dodden1 For small numbers a mandrel bender is used. Cromo will tend to kink if not constrained in a former while being bent. For large numbers a press is used (Outsourced from Taiwan)

[@CarlosAlbertoValdesAlfaro]

Me siento taaaaan inutil jajaja me asombro tu video, excelente trabajo. Saludos

[@rongpockle]

The noise during tig is pulse not AC. AC is good for Aluminium. Pulse is not necessary but it helps get a nice weld with a little less heat and good penetration on CroMo.

[@stroisya]

Классно! Молодец!

[@valveman12]

Gr8 vid! I see you were using Pulsed Tig. What were the settings?

[@Bluuplanet]

I have a hypothesis about why recumbents are notoriously poor at climbing hills when compared to standard bicycles and what to do about it. People who understand mechanics know that you can transfer the most force into turning a crank when the force vector is at 90 degrees to the crank arm. But there are some additional factors to consider: First is that straightening and bending a knee is a complex movement and probably has a "power band" (to borrow a phrase from internal combustion engines) that may not coincide with the 90 degree angle mentioned above. Secondly, you can stand up on a regular bicycle and get full advantage of this power band by storing potential energy using your weight and allowing gravity to buffer putting that energy into the crank at the best moment. Thirdly (and perhaps most importantly) while you are standing on your pedals (pumping), you can shift your weight back and forth slightly so that the 90 degree angle mentioned above is not just a passing flash but can be extended through several degrees of rotation. Some, if not all of these issues can be mitigated through mechanical design changes. Possibly a sliding spring loaded seat, an elliptical sprocket, springs elsewhere designed to buffer energy, or maybe something besides a crank attached to a sprocket to transfer leg motion to the chain.

Bluuplanet : what when you are 65 on medicare, u gonna ride a trike run your mouth.

[@vapeapes9271]

what size pipe is that and how thick is the wall on the center beam beautiful

[@rongpockle]

Mostly Tigged but some trikes were migged. Brazing only for bidon bosses, cable guides and clamps.

[@storxusmc]

enjoyed your video.. i wish i had access to a TIG to learn on..

[@jedediahbc]

I've been welding and fabricating for over 20 years working in sheet metal shops and aircraft manufacturing plants I'm a cyclist myself, I ride over 15 miles a day on my bicycle. I've often wanted to build a road bike myself out of aluminum stock and of course it will be tig welded, I would also be interested in building a trick also. I am interested in getting into the business of manufacturing custom made bicycles and have large shop I could work out of at my home

[@pedalvoador99]

brazilian song is really nice!

[@rongpockle]

Also I have never had a weld failure using stitched MIG (have done probably over a thousand frames this way) but I still prefer to TIG thin walled cromo.

[@pablouvedoble]

How hard would be to add a steering wheel insted of the classic recumbent steering? I know it will be heavier, but I don't really care. Looks so much funnier.

[@Godscountry2732]

what type of tig welder,size.Did you design the bike and all the assembly jigs ?Is this your company ? thanks for posting,giving the rest of us a little insight into what goes into building a recumbent trike.

[@danielbispo8609]

A música é brasileira, traz paz ao ambiente de trabalho

[@com2stay]

Hello nice work. Why does it makes noice when you tig weld? Do you use Alternative Current? Nice music by the way. Best Regards

[@heatice77]

I guess this is why they are so outrageously expensive

[@jeeprubicon6650]

Isaac it’s unjustifiably expensive. You can build your own for 20 times less. It’s not like the king of England built it.

[@heatice77]

Jeep Rubicon I don’t have the skill set to build it, wish I did since building your own is so satisfying

[@GoldenSim27]

Awesome job! why are you making spot welds one behind the other when mig welding , instead of making a countinuous weld ? Thanks

[@rongpockle]

Stitch welding with the MIG is a great technique to control penetration into thin walled tubes.

[@502deth]

clearly, the horn on the chop saw is the most critical part of the entire process.

[@TheEmmausRoad]

Is TIG welding the standard for bike building? I would have thought that MIG would have been more common... but I'm certainly low on the expertise on MIG/TIG. TIG sure gets some nice results tho.

[@dashuslab3316]

Wonderful work, How can I have one frame in India ? Can you ship it? At least give me the dimension & angles. Thanks in advance

[@paulahavens2764]

are there prints that you can buy to make your own trike.

[@jonpenningtton2176]

When is part 3 then.

[@moto9ll]

@wranga88 no it does not...what you do is weld until you see the puddle start to fall through then you let off...its just as strong...

[@Godscountry2732]

I see some aluminum trike frames being hyro formed,i'm guessing its safer,less chance of damage.

[@dodden1]

How do they bent the tubing for the seat?

[@wranga88]

welding a non continuous arc with the mig, doesnt this make for a weaker weld?

[@cristianchopper]

uau very nice. like

[@rongpockle]

TIG is standard. MIG adds more material therefore weight and is generally less attractive

[@rockystyer2136]

How did you get Bill Murry to do the brazing job ?

[@patrickmckowen2999]

+Rocky Styer LOL -- did not see it till you mentioned it - bill in his younger days for sure!

[@dominadoryabut3420]

wow----

[@trajkociklista702]

[@GustavoRodriguez-wq9fo]

Hola soy de Argentina cuanto sale un chasis de esas bicicletas

[@antoniocardosodepontalinda9009]

Eu coloquei logo negativo Por que você não conversou nada só colocou fundo musical o vídeo ficou sem explicação então nota

[@almirjackkiller981]

minuto bom, conto custa cada um! gostaria de atiquerir um👍

[@almirjackkiller981]

a qui no Brasil não se ver muito essas bicicletas ✌

[@jelielvalmorferreira6399]

ta euvi o video mas oquie isso????.

[@liejumoto3909]

I WATCH TOO MUCH VIDEO ON YOU TUBE SINCE 2011. THIS VIDEO I SAW THAT TOO MUCH BORING AND I WANT TO SLEEP..

[@ksatriamadangkara3944]

Welder tutorial? 😬

[@shawnstam]

Since its outsourced from taiwan I will not be buying one. There are plenty of guys making bikes entirely in the USA.

[@troyd-motorsport9933]

dude this is made in Australia.. not taiwan.. did he look chinese to you?
