Access hole

I've been HERE before. Trying to do up the grub screw at the base of a worm gear and wishing I had a tiny screwdriver bent at a right angle.

For a change, the solution was simple - drill a hole big enough for a tiny jewelers screwdriver to poke through the end of the chassis. This bit will be hidden behind a honking great bufferbeam so no one will see it.

Setting up the gears is a bit of a rigmarole. The order seems to be:

• Fit motor but leave it loose
• Slide brass gear along to the centre of the axle
• Fit worm gear
• Slide motor so the gears mesh
• Do up the back screw to hold the motor in place
• Side the brass gear out of the way
• Tighten second motor screw
• Return brass gear to the centre and tighten the grub screw up

What fun!
