oh dear..
No worries Bob, I can't remember many kits with that size drill. But I'm sure someone on here will correct me in a little while..:wink:
As for kit instructions, never use them and believe them to be written in blood. One you might get the kits mixed up and two they may have changed the tube size.
What you need to do each tome you get a kit out ( that's every one even if you have turned them before) and measure the tubes, then you won't have many problems. Another good idea is measure the fittings by offering the nib and cap up too the tubes just to make sure they are the right ones.
One of these. Drill Gauge | eBay Will help out. Metric and imperial.
I always measure the tubes and also measure the drill in to the gauge just to make sure I have the right ones for the tubes.
You can also use a digital calliper, but the gauge is just simple, just right for me..
