Another winter project: Straighten my (now spare) strut:
My friend loaned me his straightening fixture & bottle jacks. It's made from heavy channel & angle. Not much to look at - I might repaint it, to pay him back for the loan. 1st, I checked how far off center each end was by using our kitchen counter 'surface plate'. One end was 3/8 inch off-center, the other end was 1/8. I pushed the (full length) bushing about 1/2 way out to make measuring easier. 
This is the fixture: 
To take the twist out I offset the jacks: 
I heated on the strut just above the base plate while straightening it. I left the pressure on until it cooled off. It ticked a few times, so I must have either created, or relieved, some stresses. I over-corrected it the first time, so it took a second try to get it right. I got it to within 1/16 inch of center on both ends - close enough to align using the hull mounting hole clearance. ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |

that thing looks like an old KGB interrogation tool, it would make me talk.
actually, i c-clamp them in my press, now i know why all my c-clamps are bent, i think I'll drill some holes and mount the struts like above... good idea! you could even mount a dial indicator to watch the progress. ------------- "the things you own will start to own you" |

Eric - I just guessed as to how far to compensate for springback, wasn't a very close guess.
I'm sure you nail it the 1st time! ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |

I meant you have a good idea,
when i straighten them i go way past the point of straghtness. it seems tough sometimes and you get a bead of sweat going thinking they are about to snap ------------- "the things you own will start to own you" |

your device is pretty impressive, you could position the jacks to get the twist out, most times they are twisted and are a beeoch to get the twist out of the struts ------------- "the things you own will start to own you" |
