What is the method to make a simple bearing block manually, eg. no CNC ? Let's say you need two bearings, one on each side of a piece of 1" aluminum with a 1/2" hole through and the bearing pockets on each side to hold .875 OD x 1/4" bearings. I have already tried this and made pretty much a mess. Also since bearings are usually a little under sized the pockets might need to be a tad smaller for a tight fit. If there is a thread on this I could find it.
Thanks
