Parks 10" Superior restoration
      #3996103 - 08/20/10 09:13 PM Attachment (164 downloads)

Hi all, Looking for some help and advice. I'm completely new to telescope and I stumbled across a great deal on this scope. The mirror was confirmed by Parks Optical to be a 10"/F6.1 and to my untrained eye looks to be in very good shape. The scope is about 20 years old. The mount needs tlc (bad paint, rusty hardware, but it all works). There is one problem with the mount. It has a drive motor broken off. The motor label says it's from hanksmotors in Reedburg, Wisconsin and runs at 1 rpm. Was this even the correct motor? It's for moving the scope left to right (when the balance weight is down vertically). Already looked at Jupiter with a 25mm Parks Gold lens and what appears to be a Parks adjustable barlow. WOW!! My daughter and her friends can't wait to look through this scope. Any advice on upgrades, pictures, restoration processes, etc. all welcome. Please.

You need to raise the RA axis to the same number of degrees as your latitude. You're in MN, the mount in the picture is set for observing somewhere in Mexico.

That will improve your tracking and allow your setting circles to work too.

Adjustment of the RA axis is always a clunky and inaccurate business with these old mounts, it is one of their chief defects in comparison to modern alternatives. Basically you'll have to get an angle measuring gizmo (with the swinging needle) at Home depot, put it on the RA shaft, and do your best.

Even if your motors are not operational this will improve the functionality of the scope, because you can then "track" just by pushing on one axis.

You found a wonderful telescope Aircoffee. It looks in great shape too. Those Gold series eyepieces are excellent, I use them in my binoviewers for superb views.

Restoration? Check out this thread . Dan is one of our resident master telescope restorers and you'll find in that thread a whole lot of great techniques with pictures and just a complete understanding of how to get your new beauty back to original or better condition.

BTW, welcome to the Classics forum and don't forget to keep us posted. Good luck.

Thanks for the responses. I greatly appreciate the help. When I was viewing, I had it up around 44 degrees to match the latitude. Guessing it was in storage for many years.

Hi Paul!

Welcome to the CN Classics Forum! You certainly have a nice scope and it looks to be in very good condition as well. I guess the first thing to do is assess what needs to be done and then take it from there. The best thing to do during a restore is to take lots of pictures (and post them here) and take lots of notes. Detailed pictures and notes will definitely help when putting it together again.

I don't know of any documented Parks restores, so chronicling your progress here is a great way to help others that come after you.

Remember, the first rule of telescope restoration is to never use a hammer. Rubber mallets are okay.

We're looking forward to seeing you go for it and look forward to seeing the progress!

I just ordered a replacement motor from "Edmunds Scientific. The drive motor is manufactured by "hmimotors", model 3440, 12 volt, 1 rpm. As I continue working on this scope, I'll post info and pictures.
I also need help with a wiring diagram for the hand controller. The original hand control is missing. Thought it shouldn't be a problem to make a new one.

Hi Paul, I might be able to help you out on figuring out the wiring if needed. Send me a pm to let me know where you are and we will see how far you are from me.

At the attachment point for the DE motor, am I missing a gear or does this shaft come out? I noticed on the threaded shaft that there is a set screw. If it does need a gear, anybody know what size and # of teeth?

no gear needed.
set screw tightens down on the flat on motor shaft.
looks like that one should come out.
on the other side of bracket mine had a screw that you loosen when you want to adjust dec by hand.
that way you do not strip gears in that chintzy little motor.

Thanks Brian, that's what I thought, but I don't want to take anything for granted with this scope. Here's another pic. This one is on the backside of the RA drive. What's that knob and the white lever for? I have had the cover off and looked at what appears to be a clutch drive. Pic's of that later. I've taken over 30 pics so far.

I'm betting it was an abbreviation for Stainless Steel....

Welcome to CN Paul.

I can't help much with your Parks but if it's anything like a Cave it all comes apart fairly easily and should be fun to refinish and restore.

Looking forward to pictures of the process...

Thanks Jon. It looks to be a lot like your Cave. The paint is yellowing, so I plan to repaint it. Maybe orange and white with a big "T" on the side. (did I mention,...I grew up in East Tennessee). Actually, Dan has inspired me to get to work on the mount and clean this baby up. Honestly not sure about the tube color yet, but it will be refinished.

Take care (saw your scopes....nice collection!)

Looks like things are nicely shaping up and you will have a great telescope.
