Roll bars Part 4

After repeating the process for the other three holes we were ready for a trial fit and shock horror they didn't fit ,
last of the big hole before the trail fit
After 5 mins of panic it transpired that the roll bars were not parallel .Panic over and we needed a way of stretching the bars apart , settled on a trolley  jack which worked quite well
using a trolley jack to make the bars parallel again
after this bit of fettling the bars go in very nicely .
roll bars fitted the wrong way round
Now comes the hardest part ,Drilling the 3rd hole, First issue is that the third leg bolts on to a bracket which can be moved so the stud idea would not work ,next we measured the leg of the roll bar and discovered that it wasn't in the middle  so using triangle theory wont work either  After discussions with Steve as to the best way we settled on placing the roll bar the right way round and balancing it on the top of the body using a sprit level to make sure it was upright in both planes .At this point we would draw round the roll bar to give us an approx  place and then drill a 2mm hole and again used the plumb bob to see were this was in relation to the hole .
Amazingly we were less than 2 mm out ! result so out with the hole saw .

roll bars dropped in the holes
Next came to trying to bolt them down , tried the bolts in the holes (1/2 unf)  and they wouldn't  start , all stop until a tap is sourced .
