Here's my black tube Edscorp Pal Jr. I forgot its different.

The stalk actually looks like its for the binocular prism bent down to a 45

I guess when something has been in continuous production for all that

time there will be variations, and not to mention changes made by the

owners.

If you look close you will notice this tube is factory drilled for two sizes of

finder, the single stalk standard 6x24mm which it came with, and the twin

mounting ring 6x30mm you could buy from the catalog and was standard

equipment on the "6-inch Reflector."

ungh, have to get to it.

 

Anchor, I'm thinking after Edmund. I have original papers, haven't looked at them in a while. All anchor style, roughly 1960, some CN string probably with more.

Later 50's or early 60's.  The average varies:)

 

Flat as a flitter flat, one flat flat. Nicely octagonalized thing. Still in good shape, I looked down the focuser. I'm sure it's original, came with set of SAE engraved black eyepieces in box.

Ah here we go lol.gif  ...... with...." What came first , the chicken or the egg "  lol.gif ..... As per phone chats with Fred Janicke .

Fred said ...." Edmund bought the wrights from Anchor Optical " .shrug.gif  Anchor Opt. was just around the corner from Edmund .

 

Niel your secondary mirror and stalk is exactly like the one in my  WVC scope .

The only difference is that my WVC scope's mirror is a perfect rectangle . ( reference first image ... Far left focuser / secondary assembly )

 

Second and third images are of my black Anchor Optical telescope and secondary mirrored prism .

Be it Homemade or be it factory made I might not ever find out . At any rate I have chosen the middle of the road with this one . Be it homemade or be it a factory production made telescope  one thing is for sure ..... IT HAD A VINYL WRAP . With that said , I have chose to rewrap it again with a white vinyl wrap .

I had a stroke of good luck today . I went to my local fastener warehouse where I'm on a first name basis smile.gif . Picked up enough 8-32 Stainless screws and acorn nuts to do the OTA over $4.35 . Then I stopped in at my local vehicle wrap and sign shop . Ask if they had a scrap piece of white vinyl 4' X18" at least . The associate said will this do ?  He held up a roll of  snow white vinyl  at least 4' X 5 ' . I said " that's more than enough , how much ? "  He said " 20 bucks ? "

I said SOLD !  dancey.gif  I went home and stripped the old vinyl off the tube  with a heat gun . Great you say ,well hold on , the vinyl came off but the adhesive 

stayed on the tube . With an old credit card and some MEK , I got all the glue off ,then scotch bright - ed the surface . Everything is good to go tomorrow

for the application of the wrap ( pictures tomorrow of how ----- I ----- do this )  .

STEP 1 :

 

Find where you want the seam or over lap ( start and finish ) . In this case I used the original location , 180* out from the focuser hole . Make a mark with a sharpie on one end . Then make another mark at the other end parallel with the tube axis and inline with your first mark . This should give you reference points for your straight edge of the new vinyl .

STEP 2 :

 

Now lay your vinyl wrap material , vinyl side up , backing side against the tube surface . Align the straight edge  of the vinyl with your sharpie marks . Hold in place with small pieces of masking tape til placement is satisfied . Then I usually back up the small pieces with one long run of 2" masking tape pressed and rubbed firmly into place .

STEP 3 :

 

Now take the lose end of the wrap material and lay it gently back over your anchor tape , exposing the backing side up . At this point you want to expose the leading sticky  edge of the vinyl by folding  back just about 1-2" of the backing  only .

STEP 4 :

 

NOW the fun part . REMEMBER !  Work slowly and always start at the center and work out to each of the both ends .  Flip the vinyl back over the tube slowly as you press from center to the ends . Backing should roll out on it self as you work it out , you might have to help  it along a little at a time . Warning ! at no time remove all the backing and try to lay it down ,  leave the backing on as you go   .

STEP 5 :

 

All the way around and back where I started from . At this point I remove my  2" anchor masking tape .  I have decided that the reason the old vinyl covering failed  was that it had a butt seam with no overlap .  3M Di-noc recommends  an 1/8 " - 1/4 "  overlap . I went with 3/8" ( more is better attitude ) . After 2" anchor tape is removed . Place a layer of 2" masking tape over the starting end with tape edge even with the exposed edge of the starting vinyl edge .This is to protect the under lying starting vinyl from the final cut . Measure in from the tape edge your desired overlap and make marks as described in STEP 1  . Now lay another piece full length mark to mark  to denote overlap distance .  This added tape edge will transfer through the vinyl and show you where to make the final cut .

STEP 6 :

 

Now take a straight edge and a Exacto knife with a NEW blade . Place the straight edge atop the vinyl and the double layer of masking tape back in from the crease just a smidgen and lightly cut along the straight edge over the double thickness of masking tape ( just thru the tail end vinyl only ). After final cut is complete and excess material is removed you can then remove the Guard Tape and trim the ends and holes with the Exacto Knife .

 

There you have it , Good Luck

" Baaleaveee Meee "..... Terra , I came Real Close . coolnod.gif     In the end , I decided to honor and pay due respect

to the original builder ,  and return it to the Glory Days condition of a time gone by . First thought was ,

" This ain't nothin ' make a HOT ROD " .  After further inspection of the original construction I changed my mind .

There are subtle attention to details that this builder did in the mount that will be discussed later  .

I strive to stay as close to original as I possibly can  ,  and this scope Originally had a White Vinyl Covering on it ( But not in the best of condition ).

If it wasn't for the seam , you'd swear it was powder coated .

Just my 2 cents. My 3" white tube reflector was bought in store Back in late 50s if I recall. It was/is a cardboard tube with a white gloss paper. During my subsequent trips to the store from then till closing, to "shop", I never saw displayed scopes in vinyl covering. My two Jr scopes (4 1/4") were painted white tubes from 60s.  Did not know that Anchor Optics was in Haddon Heights (town I drove through later on)?  IF I get to Jersey this summer, I will try to check this out.

 

I do recall Norm telling me some time ago that the various scope mount parts were farmed out. Too bad he didn't recall where/  But nada on discussing the OTAs.

Thanks for the Change penny.gif penny.gif  , Starsareus lol.gif  . I  thought this scope was Edmund or Anchor at first  . It is built with parts that

both companies used  . The optical tube does show evidence of being mass produced by someone . If homemade it is done well .

You need to rewatch Happy Days. After Richard Stahl’s character explained the merits of vinyl to Fonzie I was convinced. But I was young and Impressionable

Lovely work, Tom. That looks a heck of a lot better than I thought possible for a stick on covering.
