Easy to drill them, but easy to drill them in the right place? 

Yeah I need to look into drill blanks, I had a few bent hollow axles. I thought the reduced centre would be required for the slot it pod as I was expecting to use an nsr motor, and from memory they don't fit?  But as the slot it motor won out I can revert to a normal axle. The hollow one was just a 2.38 axle I had handy to replace the nsr one.
