All,



I am preparing to shift from my 900 to a 1200 mount and had a couple of

specific questions for those who have already done so:



1. I have an 8" Le Sueur Astropier for the 900, does their 8" to 10" adapter bolt

on to the top of my existing pier or must it be welded?



2. My current pier is 48" high and is used with a 155 EDFS. I assume I need

to shorten it a bit for the 1200 mount with the same telescope - how does 42"

work?



Thanks,

Rick Gilbert

Rick, I have an 8" Le Sueur pier and an AP1200. I just used a 900

plate on the pier (which I assume you're already using) and bolted

the 1200 plate right on top of that (after removing the azimuth block

and drilling a couple of holes).

Have no idea about the pier

But when I went from my 900 to 1200 mount I went from a 48" pier to a 42"

pier since the 1200 mount is taller than the 900 mount

Rick,



I have a 48" pier with an AP 155 and it works fine. It is at a nice height

and I am 6' tall. What Jim did for his 8" pier seems to work well for him.

HTH.

If needed, I would actually buy a new peir for about $800-$900 vs. just adding

the peir adapter for about $400.

Rick,



I shortened my pier myself. It's a snap on a band saw. Just wrap a piece

of masking tape around where you cut so the paint doesn't chip. The

aluminum is easy to cut. If you don't have a band saw, just offer to

replace the blade on a friend's saw if he is concerned...they cost about

$10.



You may need to do a math to calculate how much you can cut off since the

stays only come in certain lengths. However the are also two lengths of

turn buckles (4&7 inches) as well. ONLY cut the bottom! g>





I was able to cut 12" off my 42" pier but had to buy new stays and

turnbuckles. the whole modification was about $120 and ten minutes of work.





Just a thought,

Be very careful cutting anything round on a conventional bandsaw (vs

a metal cutting bandsaw) as there is no support under the cut at the

beginning and end of the cut. This can result in the blade grabbing

the work piece and violently (-understatement) pulling the piece out

of your hands. Carefully plan how you are going to make this cut and

make sure that the piece is very well supported so that it can not

roll or pull you into the blade. Or better yet get a pro to do this

cut for you as one trip to the emergency room would easily pay for

the cost of getting it cut safely. I am speaking from experience as I

am very often cutting logs on the bandsaw for woodturning. To safely

do this I have created a special cradle to hold the log while it is

being cut.

Good point Scott...I have extensive woodworking experience and agree with

your caution. However, at least in my hands ( I still have them :O), it was

an easy task.
