[QUOTE="brittf, post: 2409676, member: 121792"] Wow, nice shop. I started my shop to support a university 'bicycle club' for students who wanted to design and build custom bicycles. I am pretty much completely tooled up for custom bike frames. I have a Precision Matthews lathe (may be the same one in your pictures - the gunsmith lathe made in Taiwan) and a Precision Matthews knee-mill (again, the Taiwan version that is a Bridgeport knock-off). I will definitely come by and check things out. I am at (512) 415-6938 and in Georgetown, off of HW29 in DB Wood Ranch. I don't know why, but my biggest 'lathe fear' is threading into a shoulder without a relief groove. Everybody I know uses a relief groove when setting the shoulder for headspace and then threading the barrel tendon. Sensei FORBIDS a relief groove and insists upon threading right up to the shoulder. He can get away with it because he is a former Tool & Die maker from decades ago and has a cool little analog dial on his threading lead screw that he uses to precisely stop the threading. The big analog dial works a LOT better than a digital DRO or trying to watch the handle dial. I don't have one, so I am convinced I will run the tool right into the shoulder. It is kind of like golf - if you VISUALIZE hitting the ball into the water, then into the water it goes :) So, I have to decide if I am going to follow Sensei's dictum OR ignore it and use a relief groove. I figure he will never know if all he ever sees the barreled action :) [/QUOTE]
