Well I've ruined the SIXTH piece of 3/8 aluminum plate this afternoon trying to mill out the pieces for my tripple clamps. %^$#%$@%#@%$#@ Man I just want to freakin smash something. I THOUGHT after the last 4 I had my angles and stuff figured out, so I remade a new template and I used it this afternoon and Its still all screwed up albeit not the same way it was but its still not right.
Riddle me this!:
I have a paper template the exact dimensions that my clamps need to be (I checked before I did the first trace, and I just checked it again every single angle and which way possibly). I placed this template on the aluminum plate and traced it out with a black ultra fine point sharpie black magic marker. I then went right across from it and traced out another one with the exact same paper and sharpie. I then put this in the mill and spend probably a half hour or better on setup ensuring that when I travel the length of the bed I follow these lines exactly and do not get wider or shorter at one end then the other. More or less, making sure I follow the lines exactly. With both pieces I do this. Now, I make the first pass and check it, everything is good. I change posistions and re-setup on the next line to mill another 30minutes or better of setup time. I re-dial in and check everything one last time even after it has been tightened down on the bed. I keep a very close eye on how the end mill is traveling the line and it never goes out of spot. I move the bed the length of my cut by hand and without using the powerfeed. I carefully watch the endmill stay exactly on the line from the start point all the way to the end. I then cut off the motor, un bolt it down from the bed and promptly let out the biggest string of cuss words I've used in a long long time. The thing is so cattywompass and out of shape I cannot believe it. It is 3/4 of an inch taller on one side then the other just liek the first one, HOW?!?! Both pieces were off the exact same amount in the exact same places, but when I traced them out they fit the template perfect, and the template IS correct. What in the blue hell is going on?:mad: :mad: :mad: :mad: :mad:
