Yep, that's true. I was just trying to point out that even the cheap steels are significantly more stiff than aluminum.FTFY

I replaced the quill feed with a small (12.5") steering wheel. The steering wheel does not hit the table/vise when the mill head is down like the original design. Because of the smaller diameter you don't have as much leverage as the original downfeed but so far I did not find it limiting.Ahazi... I have a question unrelated to the information you shared in post #1. What do you have for a quill downfeed wheel? Looks interesting.
Also, thanks for sharing your method for tramming and the link to tramming gauge tool. I need to do this with my mill.
I can get 0.0005 or less over 6" but I am not sure that it can hold it when moving the head up and down even after locking it in the new location. For now I am ok but I will look some more into it. It seems to be very repeatable with quill movement.Mine wasn't a whole lot thinner, and was made of steel. I was trying to dial it in to .0005" or less across roughly 12" and found the assembly had too much flex at that range. I was still fighting movement when I tightened the head. Are you shooting for that level of tram?
Thanks, you are right, my mistake.FYI low carbon steel has roughly 3 times the modulus of elasticity of 7075 aluminum. I.E. its 3 times stiffer
