yeah yeah, like I need to take up even more valuable room in my garage, especially sinse I ran out months ago... bUt...


I am starting on my hydraulic tube bender.... I already own the bender but I am getting lazy in my old age and I dont care to pull 40 pulls to do a 180 degree bend in a piece of tubing and especially with the buggy in mind there is going to be waaaaaaay to much bending to do.... easy is good Laughing ...

so I already own the power pack from my princess auto press and that was the big expense... the next one was the 2 way valve with relief that I got from p.a. as well... it was 120 bucks on sale and I also bought a cylinder today... it is a 3 inch bore, 24 inch stroke cylinder... if planned right I should be able to do a full 180 degree bend in less than 20 seconds... should be good... my cylinder is backordered and will be here next week apparently...
this is a project that will not be starting right away but hopefully I will have it assembled and working by mabey november some time?? I dunno... I will post more links and pics as I go on... any design ideas and such would be appreciated as well... Wink

all I have done so far is got all the parts and a whole pile of info on how everyone is building theirs...
I am going to start actual building of mine during the winter.. i am reorganizing my garage at the moment so i can get all of my full length steel along one wall and also am working on getting Rank out of the garage as soon as i get the rest of my steering components. as soon as this stuff gets done I can return to my bender... I cant wait!! trust me!!

ha ha!! i found this thread and lucky for me things are pretty much exactly the way things were 2 years ago so a continuation of this thread wont seem out of place!! Laughing























this is frakin sad. Rolling Eyes Embarassed

anyways, i really want this to be a winter project and i do have everything for this except for the hoses.. they will be made as needed..

here are a few good utube vids i found..

this i believe will exactly be how fast my bender will be with the hydraulic power pack i have..

http://www.youtube.com/watch?v=2MLqwlhvaA8

here is one that is just awesome fast.. i would probably use some sort of adjustable flow control valve to adjust the speed though if you arent able to feather it enough with the control valve..

http://www.youtube.com/watch?v=Gy_8jkEfO44&feature=related

and here is another of what i can probably expect with the current hardware that i have..

http://www.youtube.com/watch?v=KfxgVhlJuYs&feature=related


i really like the design of this bender... its quite neat how he made the base end of the cylinder able to come around with the tubing where the common design is to have that point fixed and just re-pin..

i need to see if anyone has any good pics of hydro tube bender stands and such.. i have been searching forever and cant really seem to find the design that i really like.. or at least a clear and good pic of one..
my steel order is hopefully getting delivered on friday and i still have some time to add to it.. i just dont know what other steel i may need and i dont want to resort to going to those fucks at steelmet for anything i forgot.. i hate those crooks..

also, i ditched the idea of running it off my hydraulic 50 ton press.. the hydraulic pump barely puts out a gallon a minute at 3600 psi.... this equals very SLOW... especially when you are pushing a big cylinder with lots of stroke..

instead, i have now bought almost everything i need to go with a electric motor running a two stage hydraulic pump.. the pump was on sale last week at princess auto and i hopefully still have a good line on a new baldor 5hp motor for crazy cheap... this should net me results very close to this vid as the pump puts out similar specs..

well, bringing this back from the dead.. Rolling Eyes

this, like many other things got put on the back burner but a few more things went on sale today at the good ole' princess auto.. today i picked up a 5 gallon hydraulic tank, some fittings, a filter base and a filter.. this will go with the cylinder, valve and hydraulic pump that i already have..

all that is left now is to buy the 5 horsepower electric motor.. princess auto has a few that wouldnt be too bad.. i am going with a "c face" motor that they have though. its supposed to go on sale here shortly again so i will wait a bit longer.. this style of motor allows me to bolt up an aluminum adapter directly to the motor itself and then allow me to bolt the hydraulic pump to the bracket.. it will get driven by an adapter that connects the two together.. its actually a pretty slick setup and makes it much easier to mount the entire unit as a complete assembly rather than making a mounting bracket for each individual component..

price breakdown as follows:

3"x24" hydraulic cylinder reg price $240 on sale for $180
bm30 single spool valve reg price $114 on sale for $70
2 stage hydraulic pump reg price $179 on sale for $100
pump adapter reg price$ ? on sale for $25
hydraulic tank reg price $170 on sale for $120
filter head reg price $13 no sale
filter reg price $12 no sale
reducer fitting reg price $9 no sale
return line fitting reg price $10 no sale

still to buy... pump couplers.. $30
5hp electric motor $349 (or with a 20 dollar bracket i can go a different way and buy the 190 dollar motor.. it looks pretty cheap though..)

http://www.princessauto.com/pal/product/8168544/Cetop/110V-AC-Tandem-Centre-D03-Directional-Control-Valve

misc hoses and fittings $45

reservoir, filter head, filter and fittings

i decided that this is one of those projects that needs to get done soon.. its been years and years.. i am sure all my bender stuff is starting to rust away.. i am looking into heavy duty casters this week and then seeing about designing an "A" frame stand for all of this to sit on..

the other thing that i am doing is that i bought almost all the hydraulic stuff to also make this an electric over hydraulic system using a remote along side the manual lever on a valve mounted beside the bender. this way i will be able to handle full length tubing quite aways from the bender using the electric remote and then when i need to be closer and more acurately feather the hydraulic controls i can use the lever on the manual spool valve..

the big push is on to get this together before winter so i can bend tube in the garage for project Rankenstein.. i need a roll cage hoop done, some new shock hoops done, a carrying basket and jerry can holder for my tire carrier done and side protection for the cruiser as well.. it will be quite busy.. i will also be stocking up on some more tube here in the next couple of months that will be for other projects to eventually come up.. i will be looking at getting a few more sticks of 2 inch .120 wall and will be buying a bunch of 1.75 .120 wall dom tubing for the buggy..

That's a pretty sweet setup.
I have some paper plans for an A frame style, it has a web link on the bottom of the page I'll check when I get home and see if the link is still active. If not I can lend you the plans.

Apparently I can't find the plans at the moment, I know I had them out when Conrad was over but I'm not sure where they went after that. Embarassed

hmmmm, mabey i should go ask Conrad what he did with them.. Laughing

just kidding..



thanks for looking anyways... i think i may go with the bender frame that i just posted.. it looks stable and pretty neat.. i guess it all depends on how you mount your cylinder to the bender..
there are really two common ways of doing it.. one way being like the bender build i just posted where both the base and the rod end of the cylinder are mounted to the bender.. doing it this way allows you to mount the bender any way you want to the stand you are putting it on.. all the forces being implied are directly on the bender itself..

http://www.youtube.com/watch?v=4SsQ5Ivl7fA

http://www.youtube.com/watch?v=q-M-GUO7yME

the other way i see quite a bit is having the rod end attached to the bender and having the base end hooked up to the A frame on which the bender is also attached to.. here are a few examples..
