Anyone ever done one of these. I was drilling the blanks. Got to the one for 17/32 tube. Drilled it actually as 1/2 inch. Tried to put the tube in didnt go in at all. Which technically 1/2 inch is larger than 17/32 by 1/32. Even tried another 1/2 inch bit to drill after nothing but dust just a tad bit bigger hole. Still the tube didnt go in. So went and got a 9/16 bit which I havent had time to try yet. But so far from my experience the instructions so far at least for drilling are way off on the size for the upper tube. Or do I need the 17/32 bit from CSUSA to do this? Or are the insturctions just that far off??
