Hey Guys,
Yep, now I've made one I'll keep it at the back of the toolbox. Once I saw the bent plate/shaft easy decision . . . I'm an I.T guy, have always done my own servicing but not too much further. Just recently started attempting more so don't have the equipment to true a shaft. I have access to some equipment at work but we're not a workshop, just sell the stuff.
When popping the shaft I had a block in place so the tine could not hit the spindle carrier and no marks on top, also took a lot of time to make sure I pressed straight down (spirit level under tine) so I think all is OK but as suggested I'll check them carefully.
