Understanding benders (& welder amps)

Im in the process of starting to finish my garage, starting electrical work and drywall, etc.

After the garage is done i'd like to start a truggy / buggy project if funds allow, ideally, as a novice, i'd prob. buy somebodys unfinished project and continue with that to learn.

With that said, Benders is one of those things that still confuse me, having never seen one being used in person.

Are tons of separate dies needed for various bends? could the average cage builder get away with one or two? In what sort of scenario might the tons of other degree dies come in handy? I see typically they are listed as ' different wall sizes and different degrees ' . Elaborate?

Is special computer software required for planning and bending?

Manual vs Hydro benders? the JD Squared, Inc. benders look * reasonably * priced. They have various models from smaller hand powered benders, ones with hydrolic rams, and pumps , etc. Are the manual hand ones easy enough to use with standard DOM pipe? 1.75x0.120 and thicker, for example - cages and ' buggy ' projects? Will I be tired and sore after making two bends? or they reasonable enough for the average person.

Also, on the other side of the spectrum. Welders... Interested in the Hobart 210, I cant seem to pull up a spec sheet off the northentool site, what size breaker / wire is required off the breaker panel for it to run safely?

thanks!

When getting a bender it's all about die choice. I went a long time with only 1 die and it never set me back. I only have 3 now and it's because I just wouldn't use any other ones.

JD2 benders are great! I personally converted mine to an air/hydro unit after my first 2 bends because I didn't want to put that much work into it. My air/hydro unit was I think $100 and I built all the brackets out of extra steel I had laying around.

I started off with only an 1.75" die and never got held up. Now I have 1.75" 1.50" and then a 1" die and am able to do pretty much whatever I want.

so basically separate dies are only for different diameter tube?

No,,there is also different size radius dies,which in some cases you might want a shorter radius,like on a roll cage,i would want a tight radius at the front of the cage by the windsheild,but a longer radius on the main hoop.

You can get by with one radius,but if i was going professional,i would want different radius dies in the same diameter size

IMO different radius dies aren't necessary for different parts of a cage/chassis. I have been building full tube chassis' for Trophy Trucks, rock crawlers and pre-runners for the last 8 years and at 5 different places, plus my shop. We have never used different radius dies. Always one die per diameter.

So what do you do...just get a die that'll make your tightest bend, and for any other bend you only go as far as you need to?

Pretty much. All of my dies and all the dies I have used, all would bend full 180*. Just becasue a die does 180* doesn't mean you have to bend it to 180*. I'll try to dig up some pictures or a couple chassis that have mutiple bends degrees and were all bend with 1 die.

Well I have zero pictures on my lap top so I ran out and took a crappy cell pic. But this chassis id bend with only 1 die per diameter.

I just use the smallest radius per tubing size. For about 5 years all I had was a 1.75"x5.5" CLR die.. built a couple buggies, a few dozen cages and a few hundred winch hoops/stingers. I pushed the bender manually for about a year, then converted to air/hydro. Finally, this past year, I went to elec/hydro (got some of the parts in a trade). With elec/hydro, I can bend to 180 deg in about 30 seconds or so..

ah, i found this image that i think explains what you guys were talking about.


http://pirate4x4.com/tech/billavista...ender/CLRs.jpg


what would be the most common/useful size somebody would typically buy for their first and second die.

Thanks.

HAHAHA now I see 2 red X's. But the secong die really depends on the kind of things you want to make really. My second die was 1.5" because I wanted to do some tube fenders and started making the seat mounts in my cages alittle smaller material. Then I had some ideas for roof racks and had a some light bars to build for a buddy and went ahead and got a 1" die. so it depends on what you want to make in the long run. But I used my 1.75" and 1.5" the most
