    I worked in a machine shop for 37 yrs. I started as a Machine Operator and ended up when the place closed as a "A" Machinist class in a union shop. I ran everything up to and including CNC vertical turret lathes with 60" tables and 12 station tool changers to a Mazak 6 table VMC. We had a Vertical Boring mill I ran that had a table/chuck of 13 feet in diameter made for Simmons of NY by Checs. I could drive a truck on it clamp it to table and cut it in half. We made parts for chemical and food centrifuges and also sewage treatment plants. Big stuff. Company was Dorr-Oliver Inc of Stamford , Ct. I also worked at Foster Wheeler for a while making boilers for ships and nuclear power plants. I making the steady rest for my lathe right now. Rainy days project. Boot

    I got the plans from the Pop Sci Archives online. They were in the November 1941 magazine article. I modified somethings to make it easier. I made the dial from two pieces instead of cutting a 1 5/8 cr shaft down to 1/2". Made the outside housing the length required which was about 1/8" too long . Overall length for my lathe was given as 3" It should have maybe been about 2 7/8". Someone over on the Practical Machinist site pointed me to the plans. Gary Hansen I believe. I would also have made the gear from brass or al if I had it. Of course the steel gear will hold up longer if I let it engaged all the time. I won't for fear of wear on leadscrew.

    started a topic Homemade Thread Dial

    Homemade Thread Dial

    I hope I can paste these picture in here. I made this thread dial instead of buying one for $100. It took about $10 worth of steel and a couple of rainy days in my workshop. I cut the gear straight not at an angle and did not hob it but file the tops of the teeth to engage the leadscrew easier. Plans from a 1941 Popular Science article showing how to make fixture to cut gear made the difference. The housing was about .125 too long and I had to shave it off with my new HF miller. It works like a boughten one. And it wasn't hard to do. Next I will make a Steadyrest instead of paying the bandits $150. Thank you , Boot <a href="http://s750.photobucket.com/albums/xx142/Boot-010/?action=view&current=DSCF0857.jpg" target="_blank"><img src="http://i750.photobucket.com/albums/xx142/Boot-010/DSCF0857.jpg" border="0" alt="Photobucket"></a>
