I have not had a lot of time to mess around with my props here of late, but I do have my HandSchaub near my desk and I've started working on cutting out the keyholes.
Basically, I took a diamond-tipped drill bit and drilled as large a hole as possible in the center of each keyhole in order to give the hobby files some room to start filing.
It's slooooow going with the filing, though. I was wondering if there was a faster way to get this task done? I purchased a Dremel diamond cutting wheel, but it's hard to angle those things in the hole(s).
Just hoping that someone's already gone through this and has a better way of approaching it?
