Remember to put the bushes in the freezer for a couple of hours before inserting them into the wood. They go in more easily and then expand for a tighter fit.

You can buy drill bits with a reduced section (called 'reduced shank' bits in the UK) for use in smaller chucks. I bought a 1/2" one for the longer (and wider) bridge bushes I bought for my ESB-4 build. This one has an 8mm dia. part for the chuck. https://www.amazon.co.uk/gp/product/...?ie=UTF8&psc=1
