The risk with this approach is that if any of the glue gets into the
threads of the broken off stub, it could end up acting like a thread
locker, making the broken piece difficult to remove at all, even with
proper equipment.

Just my $.02 and can't hurt to try. The only thing that could happen
is the bolt will shear again at the point where you glued it.

Yup. If you have a CP1 or CP2 controller, never use the Horizon Check. It
is broken in the firmware.

Hi Ajai,

I've got plenty of synchronization problem last summer until i decided to
uncheck the Use Horizon Check feature in your driver. I was able to slew to
objects when they were on the same meridian side but when they passed the
meridian, the mount tried to go upside down at each try. I've got this
problem on several nights until i decided to investigate and found that the
Use Horizon Check feature was causing the behavior . This feature was
checked during the last winter without any problem but the problem appeared
after daylight saving change. I'm running AP ASCOM version 4.1.25 and
helper2.dll is installed.

Maybe it's related or not with this thread bot i prefer to let you
know...just in case.

I have looked at the code and can't see anything that would cause
this. The code is common to all the drivers that I write and so far
no issues have been reported. Here is the code. If someone can spot
the error I am will certainly fix it:

'Get the longitude from the AP and convert it to degress
SiteLongitude = -m_Util.DMSToDegrees(CommandString("Gg"))

' Convert from AP 0-359 westward to ASCOM format +/- 180 +E
If SiteLongitude < -180# Then SiteLongitude = SiteLongitude + 360#

This is the entire AP documentation on the topic (leaves quite a bit
to be desired - as you can see is is VERY open to interpretation:

Command: :Gg#
Response: +DDD*MM# or +DDD*MM:SS# if long format
Gets the current longitude.

It would be helpful if you could send me a serial trace of what the
AP is reporting back when you query the longitude when east (I can't
get to my AP right now because it is in a dome and it is pouring rain
here - can't open the dome to get in - remote computer shut itself
down - sigh).

Please ensure that you have the updated helper2.dll installed from
the ASCOM site. This is required as the old version had a bug in it.

Re: Broken clutch knob

Dean S
 

I would take it to a shop that can do bolt extractions. I use a guy that has a wire EDM (??) machine I think it is called and he burns them out. But this is with steel cutter heads so not sure if doing this in alum is ok but they would know. I would not want to risk screwing up my mount doing it myself.

You might also try to see if it by chance is a already loose by gluing something to it and see if it will turn.

Good luck.

Re: Broken clutch knob

Stainless steel is notoriously difficult to drill. It will be hard,
and compared to the surrounding aluminum it will be extremely hard.
That is why an "easy-out" is anything but in this situation. Drilling
a small hole in the exact center of a small diameter stainless bolt
stub for a very small easy out is going to be extremely difficult and
require precise alignments, centering, and a great deal of care. If
this is the case, I would definitely leave it to the professionals.

Hi Pete,

Be very careful that the pilot drill doesn't wander off the hard
clutch screw and into the soft aluminium casting. I believe the
clutch screw is stainless steel and it might work harden when it is
being drilled. You might want to consider having a machine shop do
the job.

I think that you can use the mount as it is, so you might want to
wait until the AP folks get back from their Christmas holidays, and
then check with them.

It would be helpful if you could send me a serial trace of what the
AP is reporting back when you query the longitude when east (I can't
get to my AP right now because it is in a dome and it is pouring rain
here - can't open the dome to get in - remote computer shut itself
down - sigh).

Please ensure that you have the updated helper2.dll installed from
the ASCOM site. This is required as the old version had a bug in it.

Re: Error in AP driver

Ajai Sehgal
 

I have looked at the code and can't see anything that would cause
this. The code is common to all the drivers that I write and so far
no issues have been reported. Here is the code. If someone can spot
the error I am will certainly fix it:

'Get the longitude from the AP and convert it to degress
SiteLongitude = -m_Util.DMSToDegrees(CommandString("Gg"))

' Convert from AP 0-359 westward to ASCOM format +/- 180 +E
If SiteLongitude < -180# Then SiteLongitude = SiteLongitude + 360#

This is the entire AP documentation on the topic (leaves quite a bit
to be desired - as you can see is is VERY open to interpretation:

Command: :Gg#
Response: +DDD*MM# or +DDD*MM:SS# if long format
Gets the current longitude.

It would be helpful if you could send me a serial trace of what the
AP is reporting back when you query the longitude when east (I can't
get to my AP right now because it is in a dome and it is pouring rain
here - can't open the dome to get in - remote computer shut itself
down - sigh).

I am running the latest driver for AP GTO mounts (4.1.25)
under ASCOM 4. My mount is a Mach1.
The reported site information is incorrect: after a Get
Lat/Long is done, I get a correct value for Latitude, but
Longitude is wrong:
it reports
E 4 10.00
instead of
E 5 50.00
I checked the AP keypad: it's OK there.
So I suspect a wrong conversion... possibly for all of us
sitting E of Greenwich...


Re: Broken clutch knob

Joe Zeglinski
 

Hi Pete,

If you do decide trying a "screw extractor", to get the rest of it out, it
might be obvious, but I will state it here anyway.

Remove one of the other clutch screws, using a good one to determine how
much remains broken inside. That will give you the maximum depth you can go
with a pilot drill hole, for the extractor - obviously less depth is safer.

I suspect, that it will not take very much torque at all to ease out the
broken stub. Mere friction alone might almost ease it out since it wasn't
really screwed in tight.

Maybe a picture is indeed worth 1000 words... Here is a shot of the
broken knob:

http://www.santangeli.net/knob.jpg

As you can see, the device is actually a hollow threaded aluminum tube
with the knob part screwed into it. The walls of the tube are not that
thick, but should take quite a bit of torque without breaking. All I
can assume is that the knob got banged longitudinally somehow, and the
tube broke.

The rest of the tube (with the "outer" thread) is unfortunately still
in the mount.

Good luck.

Re: Broken clutch knob

Bob Olson <r.olson@...>
 

Hi Pete,

Be very careful that the pilot drill doesn't wander off the hard clutch screw and into the soft aluminium casting. I believe the clutch screw is stainless steel and it might work harden when it is being drilled. You might want to consider having a machine shop do the job.

I think that you can use the mount as it is, so you might want to wait until the AP folks get back from their Christmas holidays, and then check with them.
