Here is an easy idea for dealing with that pesky coiled tubing, ie: brake lines, fuel lines, and others. Again, scrap wood recycled for something useful. This is 1x4 cut into 12" lengths. Router a shallow v groove in one side according to the o.d. of your tubing. This jig is made for common 3/16". Bore two holes for cinch bolts, and that's it. A vice will hold the jig, freeing both hands to work the tubing. Use a dab of grease if needed. This little jig has given me really nice results. Probably not as good, but around $199 cheaper than the Eastwood model.
