Hi I'm looking for a C-beam build, but I still not sure about the Z axis section. If the "Working depth" is about 1.2in, for a z lenght of 6in : wasn't the spindle will move only of 1.2in, because the z section bracket being bolted to the X axis and with the lenght of the wheel ? Or perhaps more clear: Like for a 2,2in of travel, is a 7in will be needed ? Thanks
Hello JF, You can get more out of it, 12mm is easy to gain when you put the bottom of the Z axis flush with the X gantry plate. When you add longer "legs" on the sides you can gain up to 5" of movement as the plate and the lock collars take up the rest of the movement space. This is movement and not the work height; you need some height to swap out the end-mill (or drill a hole in the table) plus you don't want your router to be clamped at the highest point, clamping it closer to where the end-mill is will give you better results. The design of the C-Beam machine is just to start with, you can mod it from there and make your own improved plates easily. -Ronald
