    Sounds like you had good results with your SJ triple. I will try my SJ brace on one of my other bikes and play with it until I get it right, if possible. For my R90S with the TT triple, it was a simple bolt on an go installation (yes, I did use the plate glass and a dial indicator); now, my fork tubes are parallel in both planes. I do like the Glass method of assembling the lower sliders/axle/fender brace, it really makes it all fit together very well. I like the tube fender brace as well. If a fender brace is tweaked in any fashion, then it will mess up all your fork alignment efforts. The Glass lower slider assembly process will reveal any fault with the fender brace and one can attempt to correct it. I have the SJ tube fender brace and it was straight and dimensionally correct, allowing very good alignment of the lowers. In summary, when the fork tubes are PARALLEL in both planes, and the lower sliders are assembled correctly, it all should work together very well.

    Does anyone actually check the lower t/c? I have found several over the years that wouldn't hold the legs parallel and had to be straightened before the top clamp could be fitted properly. No sign of crash damage.

    I believe that is the purpose of the Randy Glass method. First, one checks the fork tubes for alignment, clamped only by the lower triple. If out of parallel (in two planes) one may attempt (and herein lies the rub) to tweak the lower triple and thereby align the fork tubes. Then proceed to install the upper clamp, maintaining the alignment, etc., and on to the lower sliders. Supershaft loves this method. :rofl

    I heard of the Randy Glass method but didn't check it out. Just straightened them out made them work.

    Good job! Here is one link - http://w6rec.com/duane/bmw/fork/title.html ; if that doesn't take you to the article, I have another link.

    I check lower trees. Yes some of them are bowed just like the upper plates get. I am like robtg. I just straighten them (actually, I have just got new ones but they can be straightened in a press) and go from there. The Glass method has almost nothing to do with a 'real' top tree with pinch bolts IMO. How could it? ANY perfectly machined set of trees can pull the tubes this way or that as they are tightened down if you aren't lucky IMO. It's a fact that the trees move as the pinch pinches. How else do they get tight? That movement can move the tubes. There are some good points in the Glass article but overall I think it makes the whole process about ten more times complicated than it really is. But some people like that. :D

    My brother laughs at me because of the steps I go through to align my forks. He has late model sport bikes with precision/massive upper and lower trees; one simply tightens up the clamps (yes, there is a tightening sequence) and the forks are in perfect alignment. As with any technique (Glass) for any procedure (carb balancing), we take the good points, modify some steps, and make it work in our own hands. I do not follow Randy's procedures to the letter, either. But, it is a good educational article to help the uninitiated to start to think about correct fork alignment.
