hello Guzzi: after watching a few other KZfaq 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

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.

@guzzifabrication3448 8 ай бұрын

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.

@ar5000 8 ай бұрын

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.

@ypaulbrown 8 ай бұрын

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......

@UAEE-SPRING-MACHINE Жыл бұрын

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?

@guzzifabrication3448 Жыл бұрын

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.

@fredschuttenbeld4571 5 ай бұрын

@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.

Just use 1/4" latex hose in the center of the tube.

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 !
