Can anyone tell me what would be the best suitable tube thickness for a 6 inch mirror and a 8 inch mirror. Either Sonotube or PVC.
Also, has anyone every built the Mirror-Matic grinding machine which is detailed on there site.If so, is it any good? What is the maximum diameter that the machine can grind?
