    Bicron BC408 Plastic Scintillator 5x5x1 cm for CosmicWatch Muon Detector Project
    Nov 02, 2018
    Pleased to have the parts and a friend with the right machines for drilling it.
    I was pleased with the price, delivery and response to my inquiry. I was disappointed with the machining marks. There were more by the time I finished drilling the screw holes. It is important to drill these with a vertical drill press using a collet adapter and #54 drill. We ended up using a syringe to lubricate the drilling with water using a not-fast (but not super slow either) drill speed. It helps to feed the drill in small steps withdrawing the drill between steps. It is recommended to use a "centering" bit to start the holes. I used a 4-40 tap as it had the best machined and true point. I removed some marks with 400 and 600 wet sandpaper. I used a fabric wheel and a plastic polishing rod (brown) to load the fabric wheel.
