Shift knob issues last night. I laid up a new stack of mahogany and maple. When I originally measured the knob I am copying, I came up with certain measurements for each wood. Being the nature of woodworking, I didn't mill the wood to proper specs - a little on the plus side - and the first round came out within tolerance. First knob from the second round and it's 1/16" short. I milled the wood to the exact measurements this time. I mean, metal milling measurements. After measuring, remeasuring and remeasuring again the sample, it turns out each of its layers is different. I sampled the middle... Problem fixed, but damn,
