Tube Bending Is Kicking My *** (T-01219B)

Given the comments we see here, I'm certain there's a market. Personally, I find lines pretty easy to make, but we each find our own Waterloo's when it comes to this stuff.

Kyle---certainly agree. LOL--its part of that recreation and education thing. Education, yeah, recreation---well sometimes not! They should add Frustration to that. For some of us its easier than for others. No amount of book learning will substitute for actually making the tubes---and burning through a roll of tubing in that learning process.
I agree---try it. And if you can seem to make it work, then maybe have someone help, or have them made. For some builders, its a difficult task.

Ray, Thanks for the guidance on the direction of the bevel. Makes complete sense.

Tom, despite my wanking I'm enjoying learning the new skill of tube-bending. I plan to re-do all the high-pressure-air tubing in my Yak-50 once I get a degree of competency.

Thanks,
Harry

Regarding tube straightening...

I made the tool described in the video at the link I posted earlier, and again here: https://www.youtube.com/watch?v=-Sj-vDn_O0g

It works pretty darn well. I couldn't find wheels that have a wide enough groove for 3/8" tubing, but the smaller wheels worked just fine. Below is a pic of my tool. I'd suggest spacing the wheels out a bit more than I did, more like he did in the video.

Got the wheels on amazon: https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1
I've got five extra wheels if anyone wants them. The guy in the video said he'd do bigger diameter next time, and I'd concur with that.

3/4" square steel tubing. Nuts, bolts and hardware to match. Wheels are mostly for the 3D printing world and are usually metric. A couple of washers stand the wheels off the steel tube nicely.
