nice one berg just want to say thank you also the the little plastic behind the cover that clips in the motor guest we have to drill that one out so the black plastic fits back in just asking

You may have to cut a little off the end of the tab on the black plastic piece. I did not want to make the hole go through to help keep the grease in.

Edit: I am not sure what the black plastic piece even does. I guess it just stops the heat sink from moving around on the motor.

I just carved a gear box out phenolic and it was tough. Broke a Chinese cutting bit on the last cut out. I changed the max cut per pass on the last cut out. You might want to use this latest file instead of the one posted earlier. I do not want any broken bits!

Man that is some hard stuff to be carving .I made my router table out of 1 " even used tap and die set for the holes . Not too many people use phenolic. Nice to know it can be carved with the CW.

Thx Dan,,, Ya know I'm on it !!!! LOL ... Did the bearings fit good in the piece ??? Do you need the flange or would non flanged work as well ????

[bergerud]

For me, the bearings were a nice press fit with the acrylic. The phenolic was a different story. I think the bit was bending as it cut. I had to ream the holes out by hand. The rear bearing is so tight, it needs no flange. There may need to be some hand tweaking on this thing. Motors may be a little different and the clearance between the motor and the small bearing boss is close. Make sure you get the motor sitting square. Make sure you use the last mpc posted.

So now just a plain 625 and 685 bearing? No need for the flange? Carving the back side of this thing now. Pretty excited. Making parts for the machine with the machine. Found a piece of aspen i am trying. On optimal.
