Air over hydraulic tubing bender build

[deranged]

oh I forgot to add, the vehicle will have a total weight with me in it of 620 lbs approx and should be capable of 0-60 in 1.9 secs with some fatty rear tires and a wheelie bar on the back top speed should be around 60-70 mph but I am gearing it way down for the torque and acceleration, ( geared up well over 100.... too fast ). I wanna see the look on some of these guys riding the Big sport bikes when they get smoked throught the lights by a guy in a wheelchair / electric bike LOL If I get caught buy the cops I am gonna try and play the disabled card if that doesn't work I'll have to get it registered as a golf cart type vehicle. I am adding a hidden limiter switch which I will be able to program into the controller so It will only do 18 mph ( Legal electric wheelchair speed )

HOLY FF!!!! 0-60 in <2 seconds!!! YOU ARE MAD. There must be video shot when you complete this, I want to see it.

What do you expect the total build cost to be? When do you anticipate it being completed?

Sean Murphy: I will be purchasing ( Read my " Pops " ) a drill press in a few days I will be building 2 of these simultaneously ( a friend wants one and I need the 400 over cost he's willing to pay ) I will be doing the other one with a drill press but I think I am going to have to go in much smaller steps on the bit sizes than I did in the mill but from what I have done already I have no doubts just make sure the drill press your using is capable of a spindle speed of about 250 rpm or even lower for the 1 3/8" cut you don't want the bit chattering and you don't want the chips coming off the bit any color but the shiny steel color their made of or you cutting too fast. A light amber color is acceptable if your running coolant over the bit while cutting but I just used wd-40 and went at it fairly slow although I did stack the pieces. Not necessary if you take your time and lay out each piece exactly and center punch you converging measurements and start with a small drill that won't dance out of the punch.

Deranged : I will have lots of video when it's done and expect the total cost to be around $3500 but would be lower using 4 Optima yellow tops but I would gain over 100 lbs and save only $350 . I am willing to wait and do it the way I want. If I can sell some benders it may get done really soon. should have some cad drawings soon . My RX7 Turbo Torsen Diff cam in today though so I can start on that. it's removed from the housing and I will weld up the openings and add 2 1/2" bungs 180deg of each other and fill it with 90 wt to help is be more posi than limited slip. only one is necessary but it's easier to balance the diff that way with less machining after I weld it closed. will ditch the ring gear on it and bolt a 89 tooth gear on there with a heavy duty gear protector under it cause it will dip 2" below the frame and you think I wont be getting any air with 10" travel front and rear LOL I'm going to start a build on that soon so I don't want to get too far off track on this thread so that's it for now on the Hyper-bike.

Nice workmanship. I checked out that web link to the power bender. I have a hand one for flat or small cold rolled stock. And a hydraylic one that was on sale at Princess Auto but no really happy with it. I was really impressed by that video and it looks like a fun project. How much were the plans?

[aaxiss]

here are the links to the plans and the company that sells the dies. if you buy the plans and build one when you order the dies if you mention that you built on of franks benders they will give you 10% off on the price of the dies.

Dies for this bender --> http://www.pro-tools.com/105.htm

dies come with pins and all other items needed once your bender is completed following plans.

Small video I did showing some progress and holes laid out and drilled with a drill press through 1/4 wall 2" square tubing. More cool AC/DC Music at the beginning and end so it may get pulled but I like it

What speed are you drilling? Are you using regular drill bits? I would like to build one myself that is why I am asking questions. I just purchased several M2 taper drill bits the largest being 1", I felt that using the taper bits would be more accurate. The pro-tools plans calls for a couple 1-1/2" holes which would be difficult to do with a reduced shank drill bit. I am still holding off the got trikes plans until I see how your build comes out.

[aaxiss]

I'm cutting in about 200 rpm , only you keep the heat down and the bits from chattering. I think if I went any faster I burn up the bed and make a mess of things. I got my power gig today so you should see some welding within the next couple of days and a lot more progress. I'm going to some welding the frame up and should start moving along fairly quick then. I'm on the bus right now so you have to excuse any typos dictating this as we are going along. just a tent for more video in the future and I will keep you updated everyday or so once I get moving along.

thanks for the interest.

I used a 90 degree die 1-5/8" tubing. I have about 3 dies that I bought for the bender.
my street rod frame using some tubing bent with the bender.

have fun

I have the protools bender if want pics and measurement would be very easy to build . This is the company that makes it http://midamericanonline.com/tubing_benders.html protools just sells it . i got mine from the company that makes in Iowa

I have the free prints that pro tools sends out, I wanted to look at gottrikes plans, so I ordered them.

I like the gottrikes better mine only dose 90 bends max . i had the 180 bender at one time but sold it wish i kept it .lol the bender is cheap to build ..its the bending dies that kill you. sorta like this one it uses 120 degree dies the problem with my bender the upper part is in the way when trying to go past 90 degrees
