Cabin frame, roll bar, dunno.  That upside-down U-shaped thingy that keeps your head from snapping off in a rollover.   I made the cuts for the radii of the F-631D angles and got everything lined up for drilling.  This was one of those things I needed to get absolutely right, so I spent a good long time measuring, double checking, measuring, clamping, and finally marking where the angles will go.  I sort of used Mike Bullock&#8217;s method, where I clamp the roll bar to a straightedge clamped to match the angle of the front of the skin ears.   Mine was a little different, in that I kept the roll bar on the whole time instead of using pieces of equivalent thickness, then marked the outline of where the angles lay.  This will get me where I need to be for drilling, although i might try the other way when I get home, since I haven&#8217;t committed to any holes yet.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>1.5 hours.
