Re: Double Flare Tools - any experience?

I bought a $25 Performance tool version that looks very similar to your harbor freight model. I practiced several times on a piece of scrap tubing before I tried a double flair, and was able to make all twelve of my flairs without redoing any- although I did almost forget one of the nuts once!
Tips that I found worked best for me:
- Ensure your tubing cutter cuts straight (the expensive tool is perhaps more important here)
- Verify the inner and outer edge of the cut end are burr free and have a slight chamfer on the inside and outside. I used a 14 degree tapered die grinder bit in my cordless drill for the inner; that worked very well.
- Putting the tubing bender in the vice prior to bending was a huge help!
- My bender instructions stated to tighten the clamp further away from my work first. That seemed to help, and after I got everything hand tight, I tightened the clamps a bit more with pliers.
- I used a little dab of Sil-Glyde to lube the tubing end.
This is how mine turned out:
EDIT: Also, my practice flares were conducted on a pre-flared piece from Napa that I cut the end off of, but my actual brake lines were on a coated steel line from a local auto parts store that I bought in a 25' roll. Not only was the roll a lot cheaper, I thought it was much easier to work with. Best of luck!
