Brief Description: Rear Spars: Aileron push rod cut-outs
I drilled the majority of the metal out for the aileron push rod cut-outs using a unibit and a hand held drill. I then finished it of using a Dremel tool with a sanding attachment. The Dremel made very short work of the aluminium and, at the same time, was very easy to control. Finished off with a deburring tool and a scotchbrite pad - it all came out great!
