Hi everyone,

I'm confused as to where we stand on the undersized shaft issue. In
summary:

1. Is it beneficial to insert a third bearing in the RA axis up near
the pressure plate?

2. Is it relatively easy to insert?

3. Will Scott sell us an additional bearing, and if so, at what cost?

Thanks,

Steve

Ditto everything Steve has said, except I need to fix lower dec axis,
RA seems fine.

Hi Bill,somewhere's back a few days (wed?) I posted my results.
The 3'rd bearing part numbers were posted too but I am in a different city today so can't get to my paper file to get it for you again.
The 3'rd bearing make a big difference if your is one of the g-11's with the problem.(easy to tell,lock down dec clutch and manually slew dec.If it turns smoothly you don't have the problem...yet.If you feel a shaft movement it's because the slack in the beraings causes the clutch to tighten the axis off centre and in slewing the shaft breaks free and moves back 10 or 15 arcsecs.)
The 3'rd bearing can come in different lengths but I used a 1" long bearing and it made a big difference.

Hi Jimmy

OK, according to your post on sct-user's group #12966, I need bearing
set skf ba2016. Since I don't use digital setting circles, I can seat
the bearings using existing washer set (sans needle thrust bearing)
and
clutch knob. It's as simple as that, right??

Bill

yes.mine went in 3/4's by hand (very easy,slight pressure no banging)
I might have put it all the way in but I felt using the thick washer and clutch handscrew would seat it better and more accurately.
