This guy is a Mad Scientist !!!! Beautiful creation

[@eugeneokeeffe]

great machine, one of the best I've seen.

[@jorgecortes2687]

un buen video con muchas tomas de diversos angulos y de las mucha funciones de la maquina dobladora.....me gusto mucho y creo que es lo mejor que cuando no esta en operacion queda libre el dado central.

[@rolandocrisostomo2003]

Put some greage on the slider also you can place a degree template on the bottom of the die to get the same degree everytime, for multiple identical bends. If your pipe holder clamp is slipping you can use sand or metal dust from a brake lathe and apply some oil to the clamp then the dust. It will make it grip. But other then those tips, great machine.

[@leonardouribe2392]

Thank you.. Your machine is sow great.. And I'm sorry for my bad English.. Greetings from Colombia..

[@jackel440]

Nice job

[@Hollywood4Fun]

Very nice. Makes me wonder if a hydraulic motor would have enough torque to turn the die.

[@TJussilainen]

if it has ~5000 lb/ft of torgue

[@joseestebanramirezpelayo6959]

what type of bearing use, and which is the capacity of pump and actuator

[@markfryer9880]

Quite a machine and judging from the buggies in the back ground you have got your money's worth from it.

[@mikemakuh5319]

THAT is NICE!! Any plans to make a mandrel for thin stuff?

[@TJussilainen]

i made mandrell to bend 48.3x1.6mm 304sskzbin.info/www/bejne/h6C4qnmZeaZlba8

[@rodknudsen4876]

Awesome

[@irvingalejandrocarreonmuri4044]

¿Puedes darme los datos sobre el motor y bomba hidrahulica que utiliza?

[@andrisatrya5062]

Size chain n sprocket..?

[@beachboardfan9544]

what causes the chain drive to return when the ram in retracted?

[@moosedrummer1]

Beach&BoardFan is imagine some sort of clock spring under the die being it rolls up on a sprocket under it.

[@leonardouribe2392]

how the chain is back??

[@TJussilainen]

you mean return. there is a steel cable warped around the main shaft and other end of the cable has spring to pull it back

[@FLQ309L]

do you have plans for this?

[@TJussilainen]

no plans for it.

[@user-zc1bu5wo9w]

Good afternoon, can I buy drawings of your pipe bender from you?

[@taherashaikh8889]

Maximum pipe size

[@jay1st1st]

I need to find a scrapped forklift.............

[@Mad.Man.Marine]

Jay looks like a 50 or 60 size double chain.

[@irvingalejandrocarreonmuri4044]

¿de que diámetro es el piston? Gracias 🙂

[@TJussilainen]

80mm in main 40mm in clamp............

[@irvingalejandrocarreonmuri4044]

Muchas gracias por la información amigo Acabo de comprar una prensa hidraulica de 5hp espero me de la fuerza para poder doblar tubo de 1¼ cédula 30

[@claytonarthurdavidbishop4008]

Hi buddy, are you able to send me plans for this bender? I would really appreciate it very much if you could, I am currently in the process of setting up my workshop and am building all the tools I need from scratch, this bender would be an absolutely awesome project for me!!! Please let me know if this is something you would consider. Thank you very much in advance for your consideration friend.

[@TJussilainen]

i have never done any paper or digital plans of it.

[@metalkezzle2129]

[@jeffcoldon1496]

[@theoriginalmungaman]

[@nickpowers2528]
