I then hit upon the idea of using two different pairs of precision gage pins to measure the angle. Probably OK but I wanted something more accurate. ![]() so I was faced with having to work from an average of several readings. I have a DRO on my cross-slide which really helps but I was still not getting numbers as consistent as I would like to nave seen. When mounted vertically in a very rigid position and swept down the side of the V it allows you to travel the cross-slide considerably further than with a dti and seems to produce better results. Because of the short travel of my indicator I wasn't getting very consistent results so I switched to a regular dial indicator. To use a dti it must be mounted horizontally and traveled so the tip slides down the side of the V. ![]() As a prelude to this I've been trying to figure out the best way to measure the angle of the V-way. The steady rest on my Chinese lathe is pretty wonky but I plan to adapt a much better rest that's been kicking around the shop forever. Rig up a dial test indicator to the cross slide and measure the rise for a givenĬross slide travel and simply calculate the angle.īe sure the dti is as close to straight as possible to eliminate cos.
