greenstream Posted February 8, 2012 Share Posted February 8, 2012 Hi Im now closeing a deal on a JD2 Model3 bender and I have a couple of questions for you wise guys. I will be bending CDS 45x2,5mm. and 38x2,5 mm. The seller advise to use formers as below. 1 1/2" OD X 5,5"R 1 3/4" OD X 6,5"R And the two questions Is the radius fine for my kind of pipe ? Does the inch-size mate up with my metric size ? (1 1/2" = 38mm. OK 1 3/4" = 44 mm. OK?????) Will this work for me of will I be marking the pipe ? Thanks Morten Quote Link to comment Share on other sites More sharing options...
B reg 90 Posted February 9, 2012 Share Posted February 9, 2012 Are you trying to bend pipe or tube?? Cds is a manufacturing process, you can get pipe or tube in 'cold drawn seamless' form. Once you know this you can check if the formers are for the right size or tube/pipe. In case your not sure: Tube - Od is constant for a given nominal size. Handy for roll cages as the same former can bend different thicknesses of the same size tubes - pick the thickness to suit the loading in the different parts of the cage. Pipe - has a nearly constant bore size, as wall thickness goes up, so does Od. Theoretically you need a different former for each wall thickness of the same nominal bore. Bend radius - the material choice and any heat treatment it has will dictate the minimum bend you can make with it. Adrian Quote Link to comment Share on other sites More sharing options...
greenstream Posted February 9, 2012 Author Share Posted February 9, 2012 Hi Adrian I wasnt aware of the tube/pipe issue. What Im bending is Tube OD 45mm. My reason for asking was the the seller quoted a 1 3/4 to be fit for 45 mm. OD, but to me the 1 3/4 is only 44 mm. BUT I have spoken to the seller today and he had made a mistake and I do ofcourse need to have dies in metric size 38 and 45mm. So that one question answered.

simonr Posted February 10, 2012 Share Posted February 10, 2012 I have a JD2 bender with a DIY Hydraulic conversion - and it's fantastic. Makes the most perfect bends even in thin wall CDS tube. Si Quote Link to comment Share on other sites More sharing options...
dangerous doug Posted February 10, 2012 Share Posted February 10, 2012 if you dont match the tube/pipe with the die then the bend quality will be the same of a bender thatll cost you a quater of the price. even a jd2 that hasnt been set up properly will produce a bad bend. 1 3/4 is 44mm and that would be the die you need. talk to john at tubela engineering, i went over the to collect mine and hes a very helpfull chap. he should be able to sort you out.

greenstream Posted February 10, 2012 Author Share Posted February 10, 2012 Hi Guy's It is a JD2 from Tubela that im buying and Im getting dies in metric size, so it will be 45 mm. and not 44mm. Any thoughts about the radius ? Morten Quote Link to comment Share on other sites More sharing options...
simonr Posted February 11, 2012 Share Posted February 11, 2012 Mine is 6.5" which is a pretty good match to the radius of the top of a Land Rover roof. In general, go for as big as you can get away with as the bigger the radius, the thinner the wall it will bend neatly. I made an exhaust out of 1.6mm wall tube which it made a nice job of. 1.2mm starts to go a bit wrinkly! The bender will happily cope with 5mm wall too - though without the hydraulic mod you would probably need to be a body builder to pull the lever!

asalt Posted February 11, 2012 Share Posted February 11, 2012 I went for the bigger radius on my dies for the same reason as si , jus so you can bend thinner walled tube Thought it would be useful for my exhaust as well the place I got mine seen to have every size you can think of Ash Quote Link to comment Share on other sites More sharing options...
simonr Posted February 14, 2012 Share Posted February 14, 2012 Ash - what place is that? In the UK? I imported mine myself before they were available here. Si Quote Link to comment Share on other sites More sharing options...

greenstream Posted February 20, 2012 Author Share Posted February 20, 2012 Hi Guys thanks form your input. I'll go with these dies then: 38 mm. OD R.5,5" 45 mm. OD R 6,5" Morten Quote Link to comment Share on other sites More sharing options...
asalt Posted February 20, 2012 Share Posted February 20, 2012 Hi si sorry Got confused mine were the dies for the pro tools bender but I used them in my own home made bender don't no whether they will fit yours or not Quote Link to comment Share on other sites More sharing options...
asalt Posted February 20, 2012 Share Posted February 20, 2012 http://www.stakesys.co.uk/department/tube_bender_machines/ this is the place anyway the guy was quite helpful he seemed to be bringing a lot in from the states might be able to get hold of some for you and he's in the uk Quote Link to comment Share on other sites More sharing options...
sean f Posted February 21, 2012 Share Posted February 21, 2012 I got hold of some dies for the pro tools bender fairly cheap to try and use in the JD2 bender. Both benders operate the same way and look similar, I have never seen the pro tools version so can't comments on which is best, doubt there is much in it. Some of the pro tools dies worked fine, the 1 1/2" tube one didn't line up with the mounting holes for the follower, a big hunk of steel welded to the back and a hole drilled through that solved the problem but just be aware the dies are not always interchangeable between benders, Quote Link to comment Share on other sites More sharing options...
pcook Posted February 27, 2012 Share Posted February 27, 2012 Have you tried Baileigh Industrial, i have their RDB-050, machine is great and the tooling is machined- great bit of kit for the money, just thought i would put it out there Quote Link to comment Share on other sites More sharing options...
iomlt Posted March 6, 2012 Share Posted March 6, 2012 Price of the RDB-050? Quote Link to comment Share on other sites More sharing options...
pcook Posted March 19, 2012 Share Posted March 19, 2012 I have had it a while now, think with the machine and 2 bits of tooling it was about £1000 plus VAT Quote Link to comment Share on other sites More sharing options...
longlandy Posted March 19, 2012 Share Posted March 19, 2012 I have had it a while now, think with the machine and 2 bits of tooling it was about £1000 plus VAT They are a bit dearer than that now, about £1200 inc vat with 1 tool. I did have on and it must be the best manual bender out there, though I sold it a while back to buy a rdb 150 hydro but I now cant make myself pay the £7000 it costs with 4 dies so I now have nothing Quote Link to comment Share on other sites More sharing options...
