    Added a downloadable PDF version of the writeup and PDF of just the Parts List.

    Great Write up I will add that in setting up a JD bender like yours (and mine for now) you cannot bend "extra thick" tube When I set up my "Bend-O-Matic" I tried to bend 1.75 (.120) over 1.5 (.120) and I FUBAR'd the bender frame

    I will try and get Pics of the busted one

    and of the Modified new arms

    I'd love to see the pics. I think my JD2 arms would the the first thing to "let go". I have a drawing for the arms and would get new ones cut from thicker material. I just need to figure out how to mount it to my stand so I don't have to cut it up.

    I'm curious if bending two thicknesses of .120 is equal to bending one thickness of .250 I was hoping to bend material this thick without incident.

    For those wishing to cut their own bender arms out of thicker material, we have added a link for a "JD2 Style" arm AutoCAD drawing to the writeup. This came to us from an unnamed source and can be found under the parts list. We ask that these drawings only be used for cutting thicker arms than what JD2 offers.

    I just noticed - - your bender is Smurf colored!



    .... remember this the next time you give me chit for painting all my stuff blue!



    Nice write up, Cebby. Thanks for sharing. Now - a few questions:

    About how long did it take you to make all this happen - start to finish?
    Including the bender, what would you say your total outlay was?
    What would you do differently if you built another?

    These are just things that came to mind after reading the write-up. Thanks again!

    How is the conversion working Cebby? Bent any tube yet? I'm interested in doing this soon.

    How much $$$ were you out of pocket for just the conversion? Not the bender and dies. I got those already, I just need to convert it...and I could sell off the crap I don't need now.

    I've only done a few test bends so far. Works good though - plenty fast enough - but not too fast. Good control.

    Here's some numbers based on currently available parts. I paid less for nearly all of these parts - some of this stuff went up quite a bit...

    Pump - $429
    Valve - $77
    Ram - $149
    Fittings/Hoses/Hardware - $100
    Steel - $100

    So it looks to be around $850 at current pricing. I think my pump was almost $100 less and the ram was about $30 less.

    There's a huge Pirate thread going about Hydro Benders - a few guys use 12v power units which are less expensive (eBay specials also), but you need to run it off of a battery and keep the battery charged. I didn't like that idea personally though.

    Re: WRITEUP: Cebby's JD2 Model 3 Hydro Bender Conversion

    Cebby, ...... After reading your writeup (I must add, job well done) on building the framework for your bender I decided to build one for myself. I had some scrap 8" channel and 1-1/2"x .125 square tube laying around the shop and decided to use it instead of purchasing more. I haven't purchased the ram or other components yet, but thought I'd just get the framework done now and bolt the bender to it when I get the rest of the items. I know that the material I'm using is a little overkill, but I'm just using up the material I have on hand.

    I've got a couple of questions that I hope you won't mind answering.

    (1). What is the final cut length of the channel you used for your frame?

    (2). At what offset did you place your holes from the JD2 bender frame boltdown holes to the rear ram pivot pin hole?

    Since I am going to use the same brand of ram that you used, these demensions should be the same. I've got a Northern catalog and checked out the measurements of the ram. I just want to make sure that I have enough angle on the ram in relation to the bender arm.

    As for the final length of the channel, it looks like about 3-1/2' to 4' should be plenty, according to my measurements and soapstone layout on my fab table. any information you can pass on will be of great help.

    Again, great job on the writeup, thanks. .................. Bill

    Not sure how I missed this one. Let me go out and snap a few pics and add some dims to it for you. I started with a 60" piece of ship channel and cut about a 12" off and used it for other stuff. The top plate started out as a 48" piece which was also cut down a little.
