Four years ago this month I took a chance on a Black and Silver Manon on a Ebay Goodwill Seattle auction.

I'd seen the listing and then the following discussion took place:

Manon-Discussion-4CNs.jpg

 

Here's the description and some of photos showing what they were talking about.

10-Tri-Leg-2.jpg

Mismatched legs?

 

04-Mount-2.jpg

Messy Mount

 

Objective-Scratches.jpg

Scratchy Fungsy Scary Objective

 

Soon after, I cleaned up the OTA and put it on a Mayflower mount and then posted it in the Finds Thread.

I got started on the the rest of the kit, but because of some other purchases, I never got back to it.

Now, I finally did, so over the next few days (or maybe a week or so), I'll post it's fairly simple clean up.

Nice looking telescope. I always like those altazimuth mounts with the long forks. They look quite steady. That 5X24mm finder must be an achromatic one. At some point during the 60s Japanese manufacturers decided to go with single lenses in their 5X24mm finders probably as a cost cutting measure. Enjoy this fine scope.

These mounts do work well. The finder is indeed a achromat, but it's even smaller. I believe they say they are 19mm but the clear aperture is more like 17mm. For their tiny size they work pretty well. I've actually have found some fairly dim objects with them.

Very nice telescope!  That will be a nice little project, please do post the pictures.

 

I recently acquired a Bushnell Sky Chief Jr., similar to this.  I love how lightweight it is, it just picks right up and out the door so easily.  Plus the vixen adapter screws right in and converts to 1.25” eyepieces.

 

Sadly, mine is missing the piece circled in the photo below…if anyone has one, please let me know.

Although the OTA was cleaned up almost imediately and quite awhile ago,

I'll re-start the process with a few posts showing an inventory of the scope's conditon as delivered.

 

Manon-Delivered.jpg

Goodwill did a good job on wrapping and boxing the telescopes case.

 

Man-Box.jpg

Even though the latches work fine, a previous owner once secured it with tape.

It's a really bad idea to do that as it ruins the finish and sometimes even lifts some of the plywood laminate.

In this case it was deteriorating fiberglass reinforced tape.

It's clear coating was mostly gone leaving strands that turned into a slightly gooey dust.

 

Manon-Box-Open.jpg

The interior packing was done fairly well but the low quality bubble wrap hardly had any padding to it.

 

Manon-Box-open-rt.jpg

I wasn't thrilled to see some loose items, especially since they were on top of the cell /dewshield which was kind of crammed in the corner.

 

Manon-Focuser-SS-Number.jpg

The original owner did indeed scribe their Social Security # into the focuser.

The red tint on the label at the word SHRINE and the Gate is a bit faded, probably from lots of sun exposure.

 

Manon-Focus-FinderB4.jpg

Dust, dirt, and scratches were the name of the game, but the hardware and drawtube held up pretty well.

The finder suffered from numerous screw craters, scratches, and scrapes, with another similar scrape on the other side.

The OTA's tube had a series of small ding, dents, and scratches along its top in front of the screw.

 

continued....

I've cleaned up some dirty telescopes but this one was probably the worse.

 

Manon-Mount-1.jpg

The photos pretty much say it all.

 

Manon-Mount-2.jpg

Dust and a grayish film of grime covered everything.

 

Manon-Tray.jpg

The white specks look like spider poop to me.

 

manon-Controls.jpg

One clamp screw was bent but it will be straightened.

It will all clean up well.

 

Manon-Dia-VB-Ep.jpg

These dusty and battered accessories were the only surviving pieces.

It should have also included a SR 5mm eyepiece, a 2x Barlow, and a Porro Prism.

 

Manon-EP.jpg

The 20mm has a nasty nick in it's edge.

I've noticed the 20mm EPs that came with APL made scopes are dark gray instead of black.

They also have a different chrome barrel than the ones supplied with my SYW Mayflowers

Now, about that Scary objective.

 

I knew I was taking a chance but I didn't pay much for the scope so what the heck.

 

Obj-assembly.jpg

Like everything else, dust and a dirty film, plus more spider poop specks.

At least it had a dust cap (cut off at bottom of photo)

 

Obj-01.jpg

I was expecting so much worse, that at first glance, I literally groaned thinking they had cleaned it.

 

Obj-Sun.jpg

Sunlight showed that it was still dirty with some minor fungus.

 

Obj-Glue.jpg

It's nice to find that the retaining ring was still glued into the cell. Meaning, no former tampering.

 

Obj-clean.jpg

The objective cleaned up perfectly and with no flaws of any kind.

It did not have any index marks, and unlike most lenses, the spacers are glued to the side of the crown

 

Faux-Scratches.jpg

Remember this auction photo with those scary scratches?

 

fake-Scratches.jpg

Once cleaned somehow they came back?!!

 

Lens-Cap-Inner.jpg

They turned out to be on the inside of the dust cap! grin.gif

 

More to come...

More Manon Clean Up

 

This work was done right after the scope was purchased four years ago, so I'm going from memory.

 

Rack-Tube.jpg

Degreased with mineral spirits and then polished, the rack tube cleaned up very nicely.

But I discovered a slightly damaged tooth about an inch from the upper end. 

 

Rack-Chip.jpg

Close Up of the flawed tooth.

Whatever the cause, it was probably also responsible for the chip in the pinion (below)

 

Pinion-Chip.jpg

How does this happen... a fall?

Thankfully both bad spots don't seem to affect the feel of the focuser.

 

Pinon-Punch.jpg

One side of the axle was slightly bent. Likely from the same event.

The notches in the knobs came in handy.

I could rotate the assembly so the highest point was up, then tap it to straighten it.

I should have used something softer than the punch as it left a mark on the axle (see prior photo),

The mark it made is in the middle of the axle's relief so it also did not affect it's feel.

 

Manon-Tube-Hardware.jpg

Polished OTA hardware. The warm color may indicate nickel plating?

I always use Blue Magic and Nevr-Dull for stuff like this.

The two top left screws attach the finder. The three others attach the focuser to the tube.

The bottom three and locknuts are the finder's adjusters.

 

Manon-Focuser-cleaned.jpg

No paint touch ups were done at this time. The goal was just to get it cleaned up and working.

It's been lawhile so I don't remember exactly how I first cleaned it.

I usually use Awesome and or Simple Green followed by polishing compound.

 

Manon-Fo-Find.jpg

Greased, adjusted, and ready to go back in service.

Chris, 

 

As always, a great rescue and restoration endeavor. Couple of questions:

 

- Does you license plate say, Mayflower 814? Awesome. 
 

- What type of grease do you use for the rack and piñon?

 

Thank you,

My

Yes, It's a Mayflower 814 reference (Photoshop) grin.gif... and wondered if anybody would make the connection.

 

I think I used petroleum jelly on this one, but I usually just use some old Sta-Lube amber colored multi-purpose lithium grease.

I'm running very low and they don't make it anymore so I limit it's use to only telescopes.

 

Thanks!

Mount-Cleaned.jpg

The mount was degreased and washed.

 

Manon-Hardware-P.jpg

Then the hardware was degreased and polished.

 

Mount-Clamp-Drivers.jpg

One was straightened and both were cleaned and polished

 

Mount-Touch-Ups.jpg

Most of the chips in the paint were small so I just touched them up with some Testors Flat Black.

It's so much faster and easier than completely removing and repainting everything and keeps it mostly original.

 

Tray.jpg

I really should have stripped and completely repainted the tray.

Small chips and edges are one thing but flat spots and larger areas is pushing touch ups a bit far.

But for now I just wanted it cleaned up and working.

The OTA was quickly and temporarily touched up with Testors silver paint and the box was cleaned of the tape and dirt.

BS-Manon-Telescope-on-Box.jpg

 

These photos probably make the box look better than it was but it was acceptable.

Manon-Box-Cleaned.jpg

 

At this point (four years ago) it's clean up stalled out due to the distractions of other scopes.

 

Manon-BS.jpg

The OTA was used a few times on some other mounts since it's own was still in pieces. 

 

I kept procrastinating it's completion until I was inspired by a couple of things.

One, was the quick clean up of the Mayflower 814 I've owned since new....

 

https://www.cloudyni...3#entry11190412

 

...the other was something that was said in another topic....that now escapes me! lol.gif  

Whatever it was, I'm glad it did, since I've moved on to it's completion.

 

More to come.

Rebuilding The Mount

 

Manon-Mount-rebuild.jpg

All of the parts have been ready so I've been wanting to do this for a long time.

I really thought this would be very straight forward and more fun than it turned out to be.

 

Mount-Az-Gears.jpg

Back and forth adjustments was the name of the game.

Like getting the nut under the hub tightened with the right amount of looseness vs drag.

Then getting the worm to make the right amount of contact with the arc gear.

The end bearing that the worm rides in also had to be adjusted a few times to get it right.

For starters there was only a very light film of grease on the gears

Once everything was fitted and adjusted right, I added more grease using an old artist brush. 

Then they were turned back and forth in their travel to work it in, and any excess was wiped off.

 

Mount-Shim.jpg

The azimuth worm was riding slightly too low in the arc gear so I made this small shim to better center it.

This helped smooth the feel of the control knob a bit more.

 

Mount-Alt-Gear.jpg

No matter how I tried, I couldn't completely remove the play in the altitude control.

It isn't that noticable when using the control itself, but more so if you lift or rock the OTA.

It appears that the only way to get better contact would be to file and elongate the screw holes in the worm bracket.

Then it could be pushed tighter towards the arc gear. But, for now I can live with it.

 

Xacto-Driver.jpg

I have some small screw drivers but I also like to use old X-acto blades filed to fit small grub screws.

It works great on stubborn ones plus I like the way it feels in my hand.

 

Manon-Clamp-B4.jpg

Just a reminder of what the tube clamp area was like.

 

Mount-Clam-D.jpg

And how well it cleaned up.

 

Mount-Controls.jpg

Somehow I forgot to clean and polish the spring control, so at the same time I gave the clamping drivers another going over.

 

To be continued....

They just illustrate what some basic cleaning plus a few touch ups can do.

Thanks!

 

It's been a while and I have worked on several telescopes since this ones mount, so I probably used it, but I think I also washed the parts with Dawn. My go to water soluble cleaners are Awesome, Simple Green, and Dawn and there's not always a rime or reason why I choose one over another, other than sometimes going for the covenience of a spray. That said, sometimes it seems like Awesome will remove some dirt marks and stains better than Simple Green ,plus I can get refills for only $1 at Dollar Tree. I also tend to use simple Green or Dawn after cleaning some things that were first cleaned with mineral spirits to remove any traces of it.

Finder Work

 

Manon-Finder-B4.jpg

This first photo is from 4 years ago, when I'd previously worked on it.

After this photo, I temporarily touched it up using Testors silver model paint.

It was used straight from the bottle and without trying to match the color.

It was a bit too light, but I knew it would be temporary, so it was good enough at the time.

 

Lenses-Cleaned.jpg

This is a recent photo taken while cleaning the inside of the eyepiece and repairing the crosshairs.

(The objective is on the left and the eyepiece is on the right)

The crosshair cell is a press fit (held with a little glue) and has already been removed in this photo.

Note that both lenses use a spring metal retainer. I haven't seen this on any of the other finders I've worked on.

I wasn't going to chance damaging the lenses by removing them, so they were cleaned in place. 

 

Manon-Crosshairs.jpg

The crosshairs were long gone, so I replaced them using a couple of pieces of my own hair.

Using a magnifying glass I selected a couple that appeared to match in thickness and color.

I start by taping them down and progressively adding more tape working inward towards the cell to make them tighter.

Using a toothpick I dab them with a spot of Superglue and cut the excess once the glue has dried.

After the cell was installed, I checked them again by looking thru the finder and they looked very good.

 

Finder-Grub-2.jpg

Besides the normal adjusters, this finder mount has three tiny grub screws at its front.

One of them would not go in far enough to touch the finder and it's head was chipped from trying.

While cutting the new slot, to keep it from turning, I pressed my other hands thumbnail against it. 

An X-acto saw was used for this.

 

Finder-Grub-1.jpg

As I sawed I had to carefully keep the saw blade level so it did not cut into the bracket.

Once the slot was cut. I was able to work it in and out a little at a time (with WD-40) until it re-cut the threads.

 

This time the tube touch ups were done using a different silver paint mixed with a tiny bit of black.

Over the years the finder's adjusters and grub screws had made many scars and tiny craters in the tube.

The whole process was kind of an exercise in trial and error. 

On some of them I'd paint and then wipe them with a finger to fill them.

On others just the tip of the brush worked well enough to fill them in.

 

A couple of Before and After photos

Finder-Craters1BA.jpg

After touching up the tube, a few of the small craters had raised edges making them still noticeable.

Figuring there's nothing to lose, I carefully sanded the edges down and touched them up again.

 

Finder-Craters2BA.jpg

These are a couple others that were sanded and retouched on the opposite side of the tube.

 

Three times I completely wiped all of the touch ups off and started over before it was good enough to leave alone.

The sad thing, sometimes they matched very good, but then I'd do more and mix the color a bit off and screw it up.

The metallic nature of silver makes it very hard to tint and it would also turn a slightly different shade when dry.

While the touch ups aren't perfect it's so much better than it was.

You must be exaggerating a bit. Someone who does not know that the varnish has been retouched will never see any touch-ups.  Great job!

 

Matching a hammer paint color can be a challenge - I've experienced it myself. Some time ago I restored an old photographic tripod, painted with a blue-green shade of varnish. It was a bit of fun with the use of paint pigments, the effect is not perfect, but only I know about it. And only when I look at the varnish closely. :-)
