A little at a time!
An old racing buddy came by to look at my rod,an offered to make the glass for my windshield,wow,I gave him my 28A roadster frame to take with him and he returned with some glass in it. I know he tryed hard,but it was not fitting right and he bent the frame gitting glass in to it. I saw it but said nothing but WOW thanks and after he left I took it out and fixed the frame,plus got some new 80grit disk for my 4.5in. grinder and very slowly with out getting it hot,ground down about 1/4in. lumps,6 of them tell it fits right now,that took about 4hr. of slow work. These little things are very nice of my feneids to do for me,so no way I'm going to tell him anything but thank you,with out his help,I'd be with out glass for many months saving up $ for it[around $150+ I think} was a free-B,very COOL.
