Gary [MENTION=2366]Garno[/MENTION], plenty of advice above.
One thing I do is never refer to the instructions for tube drill size, I use a drill gauge to get the best fit so I know exactly what size it needs to be. I then also check that the correct drill bit will go through the drill gauge as well because it’s been known that the wrong size drill has been stored on the wrong place. Often smaller one but TBH it’s a pain trying to re-drill for less than 1/16th or .05mm. The drill can be easily pulled in and rip the blank apart. Not that I have ever done that of course?
So, use a drill gauge, measure the tubes and measure the drill but before you even start to drill.
As Peter above said, use a centre drill to make a start for accurate drilling. It will change the total outcome of your drilling process.
Then I cut the blank to tube length and mark on each blank the drill size. Not on the bag that the kit comes in.
