hello Guzzi: after watching a few other TH-cam videos on bending tubing, your video is much clearer than the others.....I am still having to watch a 2nd and 10th time to get it all in this old brain..... unfortunately, I am using a Hossfeld bender, and the tubing does not get pulled around like you style bender, I think I have seen them referred to as a Pipe bender....due to the fact the die stays stationary ....and of course, there is not degree scale.....thanks for all the great information......Paul in Florida
Man solid video! Just got my swag off road bender and have been looking for something like this! Most of my bends are not 90-degrees so it will take some practice but this was great!
I'm still learning how to calculate a bend in metal on the benders I make. Trying to learn all the different ways. Right now I'm trying only math. Will just be using a program when making something but want to be able to calculate without it too. Thanks!
I'd love a video on how you set the zero point, and get repeatable precision on your bend angles. I've been getting ±2° lately doing sch 40 aluminum tubing with a manual JD2 m32. Would like to get that tolerance down.
Time stamp 2:33, is that what you are looking for? or another item that can throw off the bend is not pre loading the assembly ( pushing the dies, follower, etc all to same starting point when you install the tubing.
Yeah, right there. You kinda breezed over how you preload, and how you determine spring back. When I'm bending Al tubing, there's an "easy 0°", then there's "take the slack out 0°", and lastly "somewhere north of 0° but still in the spring back region (2-4°). True 0° is somewhere in there. I'm trying to figure out how to set the angle guage to 0° reliably each time I setup my bender.
hi AR5000, if you are using bending schedule 40 Aluminum, you are bend Pipe and not Tubing..... there is a difference in the dies......but I have found, that I can use a 1 1/2 inch tubing die, to bend 1 inch schedule 40 6061 T6 aluminum and get a good result.....the OD on 1 " pipe is 1.333 or so.... I am using a Hossfeld, which I think is harder to use for these type bends. anyway, enjoyed your comment..... Paul down in Florida......
@@guzzifabrication3448 same with JD. Same rating as the Eastwood for $150 more and the dies from JD are WAY more expensive. I wanted a JD as wel but when it does the same job as something less expensive it’s hard to justify. And they all are a copied design off the Hossfield bender that lost its patent long ago and went into open production.
@@mrmidnight32 I really wasn't impressed with the quality of the trick tools dies they don't leave marks on the stock.... but the finish out quality on the dies is terrible in my opinion. Yeah I'm really happy with the Bender but you're right why pay more when you don't have to.... I'm All About cost-effectiveness
Bro. , is it better way if put a supporting rod(movable) inside of the pipe's bending zone when bend it. my thought is that below factors shall impact the unbending size calculation and dedormation of pipe after bending: 1. pipe's OD + thickness 2. bending die's size ( it's OD should be slightly bigger than pipe's OD), for example, pipe OD 1 1/4 inch+ uppper tolerance, so bending die's size should be pipe OD+upper tole.+ 0.004inch as clearance 3. bending speed need controlled 4. pipe material will also impact (hardness), so adjust process parameter above 5. lubricantion shall optimize the process
There's a few crimps on the inside of the bends. Bend with the seam on the tube facing up or down and it'll prevent crimping. Otherwise somethings a miss with the tool I suspect..
Dumb question... do you need to make guides at 90°, 60°, and 45° if those are your close common bends... or can you calc them all with a single 90° guide?
THanks for watching, the focus of this video is fabricating a radius gauge 1. for accuracy 2. zero material waste. To your question you could but then there would be an amount of guessing.
@guzzifabrication3448 you say for zero waste, but if you make just a one of piece, now you already wasted a piece of tubing as a gauge. Also without a sample piece you still need to measure (and log) the distance of the x,y axis (to accommodate the stretch of the bend) for your initial bend. For this you may leave 1 or a couple inches extra on the end of the tube and cut it off after and thus not wasting 17 inches.
Yes the follower is marked... however the follower is multi-directional, up or down is of no consequence and does not effect the bend. Thanks for watching !
Kills me that no one seems to know how to calculate the bends with actual math and not have to always use a gage. It is easy and I am a guy who failed basic algebra in high school 35 years ago.
Maybe some of us do know the math and theory but are wise enough to know that the real world introduces error that is more difficult to correct for compared to...wait for it... A radius gauge.
I see your experience is limited... especially with stainless steel.... and by the way, the video is how to accurately calculate bends which I did spot on... NOT how to bend tubing without any deformation....Maybe go to another channel to fault find....
@@mrsinkov1 You realize this is a $1500. bender... if you are bending stainless without deformation of any kind, it's because you are using industrial equipment.... Make a video, I'll watch it.
Hey man, I am not pirating you. I simply don't understand how you semi or unprofessional people have got the guts to show and teach the people incorrect way, full YT and FB of this video, spread the real skill, not BS. Also way how you do is wrong, bend accurately to measurement , use growth and gain formula, tight die and former to avoid wrinkles, no matter how much cost your bender. Cheers P.S. Keep fooling people with less experience than you got, collect viewers and money from YT, and make a living, leave the tubes tu professionals.
Sounds like you're trying to fault. Find unless you're using an industrial bender, which I am not. You would know wrinkling and stainless is inherent.... So I have a question for you, spud. Where's your free video on youtube trying to help people? I looked but I couldn't find one.... It's always easy to spot people with little experience like yourself.
Does captain aj stand for captain a@$ jockey? I looked, but I didn't see the video you uploaded that shows a better quality bend..... thanks for the comment and supporting the cannel a j.....
You lost me when you started using an already fabricated frame for references to start marks. You are using a known finished product to find your bend starting point. I don't have that luxury. Doesn't any one know how to calculate begining cuts to bends and material needed without cheaters ?
The best tutorial yet, thanks for providing this video.
It was alot of fun making the video, I hope it helps !
Great video. Just bent my first roll cage main hoop without issues or waste thanks to this video.
That is AWESOME ! good job !!
Very helpful. I've seen several videos on the topic, but this one is well thought out & well presented. Thank you
Thank you, Sir, I very much appreciate that comment !
Extremely well explained. I will make sure to share. Thank you
That's awesome ! thank you Sir !!
Outstanding Explanation and Presentation. 😎
Thank you Sir !
Awesome video. I'm new to tube bending and you taught me well.
That's awesome !! sounds really complicated at first but with some practice you can make very precise bends.

I felt excited when I realized why the bend contour at the end was different before you told us hahah. I’m learning slowly but surely
I learn everyday .... Thanks for the comment !

I tried to call you but you didn't answer..... no really dude that sucks we've all done it I've wasted plenty of material...

I love the color of this pro tools bender. But it’s literally an Eastwood bender but $120 more.

Did I not replicate the piece exactly using the gauge I made to calculate the bends??? Go build a rocket or something thanks for watching

You get a certain amount of deformation with stainless.... not so much when using steel
I saw that too... horrified!!!!
JD square model definitely does not kink stainless steel.
He had the follower die upside down
@@rickyherbold785how would that affect quality? Is the follower not a symmetrical shape?
how would go about bending a 1/2" copper pipe in different diameters? say 8" 6" 4" 2"
I really don't have any experience in bending copper, I seems a conduit hand bender may work for copper. If you try it let me know how it works.
Verye good
Comment appreciated !

Off subject... @ "3:28" you can clearly see internal ripples!!! Does the protools suck, or was tubing too thin, or... wtf?? Thanks.
I'm using stainless tubing, if it were steel there would be less defgormation. Thanks !
Nice work , what brand band saw is that
That's a harbor freight band saw, really like it
Just use 1/4" latex hose in the center of the tube.
Thanks
Good video, but @ 2:17 you show the follower, and it is scribed "up" but you put it in down @ 2:21
Yes the follower is marked... however the follower is multi-directional, up or down is of no consequence and does not effect the bend. Thanks for watching !
Gauge, guage, gauge, guage…lol
Interesting approach, thanks for posting
What would you suggest, guessing...... if you are executing precise bends this method is 100 % accurate.....
@@guzzifabrication3448 I was commenting on the fact you are spelling gauge wrong, a couple of times. Otherwise I like the video
Basically You are saying that You need to make a sample bend for every deferent Wall Thickness that You are using ⁉️

1:24 $100 dollar piece of sacrificial metal.
Yep thank Trump for the tariffs that are still in place causing the record high metal prices
Kills me that no one seems to know how to calculate the bends with actual math and not have to always use a gage. It is easy and I am a guy who failed basic algebra in high school 35 years ago.
All hail the math flunky!!!
You use the arc length formula?

@@ar5000I agree...a guage with a reference point-i use the flat side of the die that touches the tube first works for real world scenarios...
What about wrinkles, its not acceptable.
