Roll Bar Continued

Continuing slowly on the Roll Bar..  Tonight I was able to drill the upper flange and center strap..  Starting on the center strap, no matter how you do it, there is a lot of metal that needs to be removed on these to get them to fit appropriately..   I used an actual grinder which was loud and probably a bit dangerous, but it got the job done, then buffed the metal with the scotchbrite week when finished.  Then I laid it in the track of the role bar and started drilling using my pre-drilled holes as guides.  Not sure if I mentioned it, but earlier I used tape marked appropriately to pre-drill these holes at 3/32..  At this point I opened them up to 1/8 and pushed the hole through the strap using a #30 12 inch bit per the photo below.  This top portion really wanted to bend upward off the table..  So I used clamps for every hole and think I was able to keep it in check. 

I was also able to drill the rear angle that holes the roll bar support using the inner plate as a drill guide.  This probably doesn't make sense to most of you, but I think builders will know what I am talking about.  You have to back drill the angle at some point, so I decided to get it over with now..
