One look at those bearings gives me a pretty big "hint" as to why my TAK EM-11 tracks better and more smoothly than any other EQ mount I've owned!!
Looks like the project is going well, PJ!!

Thanks Ed. I noticed the bearings also, six total with four on the R.A. axis alone!

Drying went well and I felt confident enough to go ahead and assemble the mount today. Here it is - back together! (pic #13). Re-greasing really helped, making its operation even smoother and I thoroughly recommend it.
Next I placed it upon my Davis & Sanford Astro 600 tripod (this is the tripod Astro-Physics sells as the SDS400 for their 400 mount). Here are a couple of pics with my FS78 in the "saddle": (pic #14), (pic #15). The shade of green is not a perfect match to the scope and clamp color, but I'm pleased with how close it came. Not bad looking for a 19 year-old mount, eh?
After I took the pics and was looking them over, I noticed the latitude adjustment screw looked a bit bare. On the previous EM-100 I owned, there was a knob on this screw (pic #2). I don't know if Takahashi left it out when manufacturing the late EM-100's or it's just another missing part. Anyway, I decided to go ahead and machine a knob, pressing it on the screw (pic #16). There - I think its complete!!
Let me know what you think. Any suggestions? Should I paint the counterweight to match or leave it as is? All thoughts appreciated.

Looks fantastic! Great job! 
I'd leave the CW as it is. Looks classy.

It has been interesting following this thread. You've done a beautiful job, PJ. I've often wished for these sorts of machining capabilities.
I vote to leave the counterweight as is.

Thanks guys! It was a fun project and I learned a lot about Takahashi mounts along the way. I was able to get out last night to observe and everything work fine manually. Recently, I was able to locate a PD6 drive controller in Europe and it is on its way, but that could take a while.
