Bending some tube / found it funny

Ok....so like I'm bending a main hoop for my pal Eric over at Los Punk Rods and this stuff is 1-3/4 x .122 wall mild steel.

No problem right......chuck the stuff up in my Hossfeld and throw on the 6' breaker bar and damn.....can't push it.

Ok.....grab a 10 ft chunk of 3x3 boom material....stab in on the bender as a breaker and still......can't push it. "Dang."

ok......grab a 15 ft chunk of 3x3 boom material....stab on the bender and ****......I can only push it over 45 degrees.....

ok...... walk back & grab fork lift........reposition my 15 ft breaker boom tube.....and walla.........a nice 150degree bend for a driver seat old school main hoop.....

Whoah.....why did no one mention that in the tube bending thread.

Pics to come shortly. Carl Hagan aka FlashBurn Fabrication

 

where did you score the 1-3/4 x .122 ***ANIUM?????

Ray

 

Not ***anium....just 1-3/4 x 0.122 wall DOM tube, and yes......hard to believe just how hard it is to get this stuff and the 1-5/8 x .0120 was no easier to find.

Both just mild steel. Crazy how many stock car tracks, quarter mi. tracks are in / around KC and no one carries this tubing.

Go figure, eh. Carl

 

Sell the hossfeld, and buy a JD2 bender you'll be glad you did.

 

i can bend the same stuff with my jd square bender using a 3' bar and one hand. you have some major leverage problems.

No doubt, unless you're 45 pounds soaking wet, that tubing shouldn't be that hard to bend...you sure you're doing it right?...

 

Bend came out perfect and no leverage problem...just stout tube and .122 not .095

Love my hossfeld, and I've bent / built soo much more than just tube with it. I like JD's stuff, but JD2's are just too damn limited.

I've got so much tooling with my Hossfeld, the sky's the limit on bending.

I just thought it was crazy how much leverage it really took to do it. And the spring back the tubing has is really crazy too.

I'll have a pic or two up shortly.....incredible how smooth of bends these things can do. Carl

 

sounds like 4130

 

When I screw up I don't tell anyone !!

 

You guys are hard....... the bend came out awesome, just seemed like it took more leverage than I anticipated. Figured more people here had Hossfeld than the JD stuff.

Just sharing the love......not a screw up. "Dont' panic, Eric."

Oh....in case someone is thinking this is still a little too much leverage....the tech at hossfeld said it sounded normal.

Oh....and I weigh a buck80, with pretty small arms. "I'm no Hogan."

I was pushing this with NewsPaper in the 'push block' rather than bearing grease. Seems to be easier on the material, but then again.....maybe I just need to go back to grease.

All my tube previously bent has been 0.095 so I was surprised on this .122

Carl Hagan aka FlashBurn Fabrication.

 

0.122" wall is some heavy stuff. In circle track racing, we use Ø 1¾" x 0.095" wall for our cages. There's a race shop near my home that charges $5.00/bend using a mandrel, real clean & accurate.

 

Choose the 0.122 to make sure it can p*** spec throughout the bend.

Anyone else here using newspaper in the push block rather than bearing grease. I heard of that trick on the hamb and it's been working good for me on 0.095 especially on the cleanup, bearing grease is messy. And I paint the majority of tube I bend except when it's roll cage stuff.

You guys think that might be why it took so much leverage?

I have instruction manual right there hanging on the bender. No way it was set up wrong, 'cause if you have the push block anywhere out farther than it should be ....then it folds the tube with a nice krinkle like a toilet paper roll.

And the push block can't be positioned to close to the center pin or the tubing just will not fit.

Carl, try the white lithium grease in the spray can, it works really good, it's not nearly as messy as bearing grease is.

 

OK....so the wife & I went out & bent a 45degree angle in some !-5/8 x 0.125 wall tube last night. It's even beefier than the 1-3/4 which was only 0.122

I weigh a buck80 & I know if she weighs an even buck, it would be a miracle.

Still took us both pushing on a 12ft breaker bar on the bender for leverage enough to push it over 45degrees. Used bearing grease, bahhh....

Anyway....Eric....your cage is done.

Maybe this post will help give anyone an idea on the kinda force it really takes to do this stuff. I'm using a Hossfeld #2 bender.

Now.....back to bending 0.95 for some more kinded grind rails. Hahaha

Carl Hagan

 

Sounds like you need a manual bender with 3 speeds (3 levels of leverage)

 

I can easily bend 1 5/8" .083 chrome moly in my JD2 only using a 3' long piece of 1" x 2" x 16 ga tubing for leverage by myself.
My roll cage made out of 1 5/8" x .083" CM.

 

Where's the pictures at?

 

I'll take a few pics of the driver seat hoop & other brace bar tonight as I deliver it all. I'll get em posted up. "yeah....I like the JD ratchet stuff and see it works easily, but man.....my hossfeld can pretty much do anything imaginable w/out even talking about tube.....and that right there is why I turned down JD's stuff and protools stuff for that matter."

I'm bending a ton of angle, flat bar, round bar & other misc. stuff in the shop. All industrial stuff, nothing to do with hotrod.....but wanted to make this post due to how surprised I was when bending 0.122 & 0.125 wall thickness tubing.

Out of all the bending threads, really you just see pics and don't really hear about what it takes to do it. Some people think you just chuck it up & push it over & it's really not that easy.

I really couldn't see buying a bender that only does tube.......it would set in the corner of the shop with dust on it if that's all it did.

My favorite attachment for my hossfeld is the "hole punch" I get way too much use out of that one.

My friend had a hossfeld, he had to bend some 1 5/8" x .134 dom roll bar tubing, it took a 20' piece of pipe with 3 people (one guy was 6' 7" 320 lbs) to make 12 bends, what a nightmare. With my JD2 model 3 I can bend the same 1 5/8" x .134 dom tubing by myself with my little 3' long 1"x2" tube handle for leverage. You could adapt the hossfeld dies to the JD2 for bending flat, angle iron, and such, then you'd have the best of both.

 

Why dont you guys do some scrounging and rig up a hydraulic ram on the Hossfelt? My pal has one and it works great.

 

Is this for the "Hell Wagon"?

 

Ive got an old Hossfeld bender in my cl***room, I cant wait to see these pics of how your using it. I think its a great tool and use it almost daily for making everything from bicycle chopper frames to the students initials and Go-Karts frames.

 

I had a Hossfield. I bought a JD2 and have been satisfied. I had a portapower attached to my Hossfield to be able to do anything. I understand what you're saying about having many dies and such but for anything that is thick wall or larger diameter, The JD is hard to beat.

 

lol... nice try

yep....

 

Hossfelds operate on simple leverage while the JD2 and similar benders use compound leverage. A JD2 with a 3 ft handle has the equivalent power of a simple leverage bender with a 36 ft long handle due to the compounding mechanism.

 

I have done 1-3/4" 0.250" wall DOM in my JD2, manually, with a 4' handle. It wasn't a walk in the park, put it was do-able.

 

My pal Vega Bob bends all mine on a JD2. $10 a bend. I take him the tube and a cardboard pattern. I do my drop axles on what is really a pipe bender and replace the rollers with hard maple V blocks. I dont know how much bend I could do without kinking but so far I have been lucky I guess. I did the front axle for the new rail last week. I made the king pin bosses at right angles exactly as I could set up and clamp them perfectly , then bent in the KPI and axle drop using a cardboard pattern.
I want to make a roll bar bender . Way back I did bend a roll bar for a customer using a car wheel and a very long piece of oversize pipe for leverage. It worked but I have never tried it since. That was almost 40 years ago. When we built door slammers we used to get our bars bent on a muffler shop bender. Since we used oversize tubing and the proper thicknes all NHRA insectors we ran accross had no trouble with them despite the cute little shape on the inside of the bends those machnes leave. However on a naked outside roll bar they would look out of place I know.
On the Hossfeld you could easily adapt a farm jack to pull it then you would have the Hossfeld advantage with the compound leverage and could work it with one hand no matter what.. Thse jacks are under $100 and very very strong . The ends unbolt so it would be a simple matter to bolt it to your bender. They also have slide ability for fast setting before the actual pull. There is almost nothing they wont lift so the power would be there. TSC should have them as do many farm stores and serious hardware store.

Yep....this is for the Hell Wagon of Eric's. Dropped the bends off at the Los Punk Rods garage last night & everything fit up nice.

Got a few pics of the bends I made, but the files too big to post here so I'm waiting on a friend to photochop'em up so I can post.

I will be welding the ***embly in the Hell Wagon this weekend, so the car will have the roll bar in it for World of Wheels. Carl Hagan

 

If you scale the hossfeld photos it's pretty easy to make your own hydraulic setup on the cheap...ours worked well while we had it. We use plastic bags cut in strips for lube, no mess, and they are always around.

 

Here's a couple pics of the two main bends and this is a simple roll bar fab'd to meet Eric's specs.
