I took some time off for the fourth of July holiday, but got back to work over the last couple of nights. I called Vans about the height adjustment on the windscreen. The instructions say to raise the slider to even with or slightly higher then the windscreen. This didn’t make sense to me. It turns out what they really mean is to raise the slider to even with or slightly higher then the windscreen, so you can shim only on the windscreen side to make them perfectly even. Once I figured that out, a couple of shims on the middle three holes has the windscreen and slider height perfectly even. Cool, drill and move on. That’s what I’ve done. The windscreen is drilled and now I have countersunk and deburred all the holes. Oh, I used a different countersink bit so as not to crack the windscreen like I did with the slider. I bought a ‘chaterless’ bit without a pilot from Avery. I have a photo of it posted on the finishing kit page.
