BladeRunner,
Actually I have slowed down... I already snapped drills on this project... that's when I decided to slow it down a notch. I am being EXTRA careful about measuring THREE times and cutting once for the RAM and GPU depth cuts as these are the ones that are CRITICAL to this working right.
Not sure if I'll do a lot of polishing, but I probably will as this is by far the nicest/most complicated video card solution I've ever attempted.
The carbide endmills seem to work a bit better... but I guess when you work on such an abrasive metal (like copper) you just don't get much better without MAJOR RPM on the spindle.
At this point I had glued the last template for this block on and trimmed up some and am just setting the center for the rotary table so I can mill the curve part.
This is almost finished as far as rough shaping goes...
Most of the edges are in a close to finished condition. I did skip cutting that little notch on the left near the smaller circle target.
Here the back block has been attached to the unfinished front block to verifiy alignment of cap screw holes as well as water crossover passage.
The front block has had it's BACK side template glued on and it is secured to the rotary table.
Last thing for the day was to drill and mill out the keepouts for the SMCs that are at GPU height on the card(depth for milling out of the block).
Tomorrow I'm going to mill away the outline of the block shape first. THEN I will mill the depth for RAM and GPU... that way I won't have to try and line up templates front to back.
That's it folks... L8R all...
