Today I noticed something, which is somehow frustrating.
1. I found that the HF 7x12 is not a rigid machine. Well, I do not expect it rigid, but I found the compound slide and the cross slide all have some plays(I may not use the right term). For example, if I try to list one end of the slide, I can clearly see a very small gap open between the slide and its base.
I assume that the above is normal, anyway, the rotation work will push everything down, so the gaps(if any) will be consistent and will not move around.
2. but one thing, I definitely hate, is that I found the compound wheel(the upper most wheel) have a lot of play. Say if I turn it forward(clockwise), then I turn it backward(counter-clockwise), I can see the play as large as 8 marks(or 0.001" * 8 say 0.008").
I tried to adjust the gib to fix this(is this the right way> Anyway, except the three gib screws, I do not feel there is other stuff I can tune). But it is not easy, either it makes the slide to tight, or too loose.
Could anyone tell me whether those plays I observe are normal? especially the later one, play of the wheel.
