A P Find of a Life time (aveman
Posted 22 December 2009 - 06:01 AM
It always feels great to come across a find like this. Especially when we can see the item that one has bought in photographs. There most certainly is a lot of older instruments lurking out there somewhere and they come to surface from time to time. I wonder who will be the next lucky winner of getting their hands on something interesting? Enjoy it and let us know how it performs.

Well here was my first idea of what I had purchased. My jaw droped on my work bench to think an AP would be abused like this just never ocurred to me until I saw this.

I have a lot to post!!! I took notes while on the phone for 20 minutes with Roland. he was very nice and full of information that I wrote down.

I'm shocked Roland would suuggest polishing off the coatings! Any mis-step may affect the lens figure as well. Maybe I'm off here, but I'd suggest that if you go this route to ask Barry Greiner at D&G to do the work. At the very least he can do a before and after test on his interferometer.
Is there any downside to leaving the coatings on?? Is it merely a cosmetic thing when looking at light reflected from its remnants??

I'm sure you have your favorite scrap metal shop in mind, but if you don't, I've found all kinds of treasure at Industrial Pipe and Steel (IPS) in El Monte. They just emptied a bunch of their scrap bins, so they're "short" of scrap at the moment, but still have 4 or 5 bins full of aluminum. And I bet there was a bunch in the size range you're looking for.

I just spent 7 hours installing new cork padding on the 9" and cleaning up the 6" OTA it was a mess. Came out nice!! As far as the Padding on the 9" AP Roland walked me thur it and gave me the cork type to get. It is really awsome working on this lens I would guess its weight out of the cell at 30 pounds of glass. I am finding it fun to work with and have been exact with every movment. Makes you think a little more as your handeling the thing!! Note in the photo the old corks condition.

I had to be really carfull at this point as the one gallon coin jar with 12 Puffs taped to the top has almost $100 in change in it and I didnt want to spill it.
This is how John taught me to push a lens from a cell, Usualy I use a pill bottle or somthing a bit smaller.

All done with the re-padding job. I was glad when the lens layed right back in its cell with new soft pads to live on for another 25 years. this was a good job to do when your all alone out in the shop...

I've been following this thread with great excitement. I expect you'll have both big lenses up at Pinos this coming summer. Look forward to looking thru them, especially the 9 incher.
You and Debbie have a great Christmas. You've already got all your new presents!

I am perparing a photo CD to send RC, he said he will look it up for me and I am hoping he will send back a letter with the specifics he can find in his paper work,
I have found another wonderfull scope in the Brass Unitron, It has truely taken a back seat to the AP but I will be posting it in its own tread. I have the original owners manual for it!! 1954 Unitron 3 & 4 inch EQ owners manual. Wait till Robert sees it!!

The 6" F10 AP telescope was abused. Its lens has coating issues, they are degradated to a point that while the lens has a perfect star test and no color as you might expect. The coating problem is causing a Hazy Spike when you look at a bright objects. I am reading up on this. Roland said I could get someone to build a pitch lap and polish off the coatings. Other stuff I have read says it could ruin the figure of the glass?? I will talk to more folks about this.
The 9" Has not seen star light in many years, It has been sitting in its shipping box. This lens on the other hand is in very good shape. the glass was not even dirty. There are one or two small sleeks, one looks to be on the #3 surface, That means RC did that one, as the sealed oil spacing tape has Rolands hand writing on it. I am very observant and am looking for these with a bright light if you just look you cant see a mark on it. Considering its age 25 years I would give it a 9 out of 10 as far as the condition.
Merry Holidays Fellow Collecting friends. I hope you top this one in the new year!! I guess I set the bar to high for even me to jump over.. Maybe one of you guys will find a 6" Clark at a local rummage sale.
Another photo from last night.
