I just got my Big Block this weekend and have been enjoying it very much..But there was just one little thing that was bugging me...
The three vents are held in by a 10-24 screw, lock washer, and a nut..and if you want to be able to adjust the position of those vents, you can't tighten the screw and nut very much, so every time you move the vent..the nut loosens up and everything gets sloppy....sooooo, I tried to find an all metal 10-24 lock nut...but all I could find were the type with the nylon insert...not good with heat...anything I could find in an all metal lock nut was a 6mm stainless steel...all the better...so I used the 6mm,12mm long screw, 6mm flat washers (stainless steel) to replace the lock washers, and the 6mm all metal stainless lock nuts.... take a 1/4" drill bit and open up the holes in the vents and in the box...put everything together, and tighten things to your liking...you can adjust the vents all you want and they will never loosen up and fall apart on you....yes I know a 5mm screw would fit without doing any drilling but the hole for the 10-24 screw there now would be too sloppy..
Hope this can help someone else..
