Seasons Greetings, Merry Christmas and a Happy New Year to all!
I managed to get some time in on the milling machine controller this weekend and have the photographic evidence to prove it!
Here's the Hobby CNC controller mounted in the 5 1/4" cage of the computer case I'm adapting. I've got some rack-mount servers that I've retired from my hosting company that turned out to be perfect for this application: the case is large enough to fit all the controller's elements inside, as well as the computer components too. I'm mounting the CNC controller in the area that would normally house hard drives/cdroms, etc.
This is the front of the drive bay, with a panel that I made for the controller including the 24v fan, a fuse and an on/off switch. The controller will be on a separate 110v line from the computer.
Here I'm laying out the various cables etc. The 24v, 10A transformer for the CNC controller is already mounted in the case, in another cage that the controller is currently sitting on.
Here's a shot of the back of the computer. I made a panel that joins two of the pci openings into one for the stepper motor cables to pass through. You can see the AC power cord connector that I've mounted above and a bit to the left for the CNC controller's transformer. The computer will be powered by the regular computer power supply.
More coming soon as I've got a ton of projects stacking up and I need this machine up and running!
As you know, I'm rebuilding Kyoko's engine and I came across a problem with the flywheel. There are 3 shims that go between the flywheel and the crankshaft's #1 bearing that set the end play of the crankshaft.
It seems that the flywheel I have doesn't have enough clearance for the 3 required shims (as per VW's instruction, and who am I to go against over 60 years' worth of engineering knowledge?) as the thinnest shims I can get are around .0095" (.24mm).
After poking around on thesamba.com and not really getting a definite answer (it always seems there's so many people with so many contradicting ways of doing things ...) I decided to fire up the milling machine and take off 0.010" to make the necessary amount of clearance (3 x 0.095" = 0.0285" thickness, and non-machined clearance is 0.028", and required clearance is 0.004" to 0.006" ideally).
Here I am, about to either resolve the clearance issue or turn a nice shiny flywheel into 16lbs of scrap metal.
Well, it worked. I fly-cut off 0.007" and now have about 0.005" clearance, right in the middle.
