Next, we gotta set the tailstock height. This involves a center. Any reasonably accurate center will do. Pop the center in the chuck, then run a test bar between chuck, and tailstock. Adjust the tailstock to achieve equal measurements from side to side, along the top, on your test bar. Why use the chuck, instead of the taper in the rotary table ...

An analytical method for studying congestion in a railway network is presented in this paper. This method, based on statistical queueing theory and a model for evaluating congestion on a single track line developed in Canada, reduces to the solution of a system of non-linear equations which are easily solved on a mini computer.
Tramming We can't have a conversation about tramming until we all agree what it means. First let me define the players. We have the head of the mill which provides the solid support for what moves. The head is supported by the column which is supported by the base. You can see the column and base in the picture on page 2. Inside the head is ...
