Thanks for watching ! - ยานยนต์และพาหนะ
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 !
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.
The best tutorial yet, thanks for providing this video.
It was alot of fun making the video, I hope it helps !
happy to be the 1K like!! nice vid!!
That is awesome ! Thank you !!!
Outstanding Explanation and Presentation. 😎
Thank you Sir !
Thanks for teaching. Very helpful.
Awesome ! Hey thanks for watching !!!
Excellent instruction!
Thanks !
Good tips
Great video!
Thanks !
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
👍
Very good clear explanation. 👍
Thank you Sir
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!
Nice ! make a gauge in your size tubing and your good to go.
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!
Nice !
Thanx for that
👍
Egggggggggggggggggggggggggggggggggggggggggggggggggggslent video. Thanx for sharing. You Rock!!
Thank you Sir !
Thank you for that , well done. New subscriber , I will check to see if you have more about tube bending , I am a newbie.
Thank you Mr. Mencel !
Great video man!!! I wish I found this two days ago I would have saved myself 20’ of 1.5” 0.95 DOM 🤦🏻♂️
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...
@@guzzifabrication3448 oh man I’m sorry I missed your call.
@@guzzifabrication3448 well, sometimes wasting is learning......cheers....Paul
👍@@ypaulbrown
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 !
Nice work , what brand band saw is that
That's a harbor freight band saw, really like it
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......
I love the color of this pro tools bender. But it’s literally an Eastwood bender but $120 more.
I really wanted the JD squared but at the time they were back ordered
@@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
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
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.
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.
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 !
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..
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?
Just use 1/4" latex hose in the center of the tube.
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
1:24 $100 dollar piece of sacrificial metal.
Yep thank Trump for the tariffs that are still in place causing the record high metal prices
Basically You are saying that You need to make a sample bend for every deferent Wall Thickness that You are using ⁉️
The title of the video is : Making a radius gauge to calculate a bend.
Kills me that no one seems to know how to calculate the bends with actual math and not have to always use a gage. It is easy and I am a guy who failed basic algebra in high school 35 years ago.
All hail the math flunky!!!
You use the arc length formula?
Maybe some of us do know the math and theory but are wise enough to know that the real world introduces error that is more difficult to correct for compared to...wait for it... A radius gauge.
@@ar5000I agree...a guage with a reference point-i use the flat side of the die that touches the tube first works for real world scenarios...
That’s terrible bend quality
Does captain aj stand for captain a@$ 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.....
So. Many. Wrinkles. Where is your wiper die?
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.
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 ?
You could always just guess at how to achieve accurate bends....
The title of the video is " making a radius gauge to calculate a bend " that's what he did.... are you daft?
