Jack and all, The swap out is not an easy one, which is one of the reasons that we have not offered it yet. Yes, many of the components can be reused (motor assembly, worm gear, spur gears), which

I would like to know also; as a new owner of a 1600GTO with original gearboxes, I'm interested. Thank you Roberto

Don, They were only cool if they were full. <G> …but real cool was the slide rule slung from your belt in its case! Talk about a chick magnet…ah, the old days! Regards, George

George, Thanks for posting the link. Jack Huerkamp

Roland, will this be a simple swap out for current AP1600 owners. I assume that the existing worm gear would be retained and moved to the new housing for the quick release system. Any estimate on

Had one of those too. Still Have it.Ha Ha. Requires no batteries. Never needs to be rebooted! Don Anderson

Not to be picky, but they are called pocket protectors, and only the slide rule ranks higher in the engineer's kit. Mike

Pen protectors! Wow that goes back a long ways. i used to wear one every day when I was a TV Technician! Back then I thought they were cool. Don Anderson

I switched from a piggyback setup to a side by side setup and I found that it did help with flexure. But I have a permanent OBS so I only had to balance it once. It did take longer to get the right

Mike, I don’t have a definitive answer to that question, but my very heavy (12 lbs. I think) Losmandy side-by-side saddle seems quite solid and rigid for the small but heavy refractors I put on

The discussion about side to side systems has me wondering - Which has less flexure; side to side or piggyback ? Mike

A "teak" is a tiny tweak. A "tiny teak" is a micro-tweak. Let's get these definishions schraightened out! Rolando

Oops, I guess the word is “tweak”, not “teak”. Although teak would make a nice dowel rod. Regards, George George Whitney Astro-Physics, Inc. Phone: 815-222-6538 (direct

Rolando, I thought everyone carried a dowel rod in their pen protector…oh, wait…I guess that’s a pencil. <G> Regards, George George Whitney Astro-Physics, Inc. Phone:

Woody, <G> It’ll make your life easier. Only tiny teaks will be necessary on mount. Regards, George George Whitney Astro-Physics, Inc. Phone: 815-222-6538 (direct

Woops, you beat me to it, George. I call it the pencil balance (i don't always have a dowel rod laying around). Rolando

You could always do the pencil balance. It is quick, easy and deadly accurate. Rolando

George, Thank you. That looks like a very helpful document. It’s not the same procedure I’ve used in the past, but I’ll give it a try the next time I setup my side-by-side solar scopes.
