The current 1/4" collet with two cap screws seems to be a poor solution for this type of machine. Why don't you produce a 1/4" collet like your 1/2" collet that is a REAL COLLET SYSTEM. There is no way of changing 1/4" bits that have to be held-in with "locktite" each time you change a bit. The cap screws are not that great and I can't see them lasting very long. The only solution that I can see doing, is to buy one 1/4" collet for each 1/4" bit in the system. I this your marketing plan? I do need to order bits and collets from you, but can't get through on the phone, can you call me so that I can order these things from you. Tim King ###-###-####
