the mounts to the body are 3/16" mild steel plate that i heated and formed over and anvil to match the body shape. then i added the posts and built up space where the post meets the mount with weld. next, using a flap disc on my grinder, i formed the transition curves and got it all smooth. Then using a rosebud on the torch, i heated the post and formed them to the exact angles i wanted. (just a slight tweak, its amazing how 1/2 deg is visible) Now the post material is hollow, so to allow for the windscreen mount bolts to pass through and have some clamping force, i milled up some slugs and welded them in. The though bolt that allows the windscreen to hinge is a 3/8 fine thread. i did that so i can use the traditional windscreen wing nuts. (not pictured) The windscreen its self is 1/2" black pipe that i milled a 5/16 slot. this allows for the u channel grommet and the glass. The glass will install from the bottom and i will put small tac welds to hold the bottom of the windscreen frame. I still plan to mill some decorative grooves in the pillars.
