Prior to last night, I had no need for a carriage stop. I am a retired Electrical Engineer and everything I do is a planned project. Those projects range from washing the car to taking the grandkid to Disneyland. Everything is planned in great detail. (generic engineer character flaw) That works just fine until I engaged the half nut lever instead of the cross feed lever. That was not part of the plan!! In just a twinkling of an eye, I transformed a $350 rifle barrel blank into a stainless steel tomato stake! Time for a new project. I need a carriage stop for my G0709 lathe. The aging data base in my head was queried and the result was a distant memory of someone (perhaps on this forum) that purchased a carriage stop that came with a different Grizzly lathe and used it on their G0709. I am not opposed to making one, but the old engineer in me requires a build vs buy analysis. I do understand that a carriage stop will not prevent me from damaging the lathe if I do this again. (there is no clutch on the lead screw - just on the feed rod) If I would have had the carriage stop on my lathe last night, I would be out shooting today instead of sitting here in front of the computer!
