Hi,

I'm currently building a harley softail trike and was trying to do the rear brake lines with the flaring set I bought for building the kit (copper lines) and was really struggling to get a good double flare on 3/16 cunifer pipe using it (https://www.machinemart.co.uk/p/cht229-pipe-flaring-cutting-kit-/)

I found a tool via youtube from CBS (https://www.youtube.com/watch?v=kWo_E7BqrNw), it is not as versatile as the set but worked very well and gave me perfect double flares every time: https://www.machinemart.co.uk/p/draper-23312-expert-316-sae-hand-hel d-brake/

I actually bought it slightly cheaper from CBS but the postage made it about the same price as from MM.

. Work well when flaring on car steel pipes as well when replacing sections using a joiner but mine will only do single flare . Imperial version does single and double

I have the CBS type tool, although I got it off Ebay. It is very effective, easy to work with in tight spaces, and as mentioned it's good enough to do steel and kunifer.
