Mr. Galaxy Repair...

Sorry if anyone was baffled by the vanishing posts,

I decided to move this stuff to its own thread...

I just picked up a pretty clean example of this robot.

While it walks and flashes fine, there is no Up/Down

action. I assume there was once a plastic gear at the end

of the shaft in the pic...Was there anything unique about

this gear, i.e. width or material, or do I just need to find

one with the right diameter and tooth count ???

[robobob]

WHOO-HOO ... My 400th rambling post !!!

Ahem....

Also, I thnk the white plastic gear track has warped in on

one side...I am assuming it should be the same spacing

on both sides, that is, all the way around ?? I am guessing

the gear extends like a rotatomatic shaft, and then makes a

circuit all the way around the track, befor dropping back out

at the bottom. Seems like it will pinch the way it sits now.

Thanks as always for your continued support !! :)

One more pic....

sorry bob, i dont own this robot which means.......... i havent repaired it. :D i will be watching though!

good luck

[robobob]

Update...

Upon further inspection, I discovered the source of

the rattling noises I could hear inside one leg. Namely,

little bitty pieces of my missing gear !

Using the forensic skills I have picked up from watching all

those CSI : Miami episodes, I have managed to crudely

reconstruct the gear.

It looks to be a 9-tooth pinion gear, but since I don't have

anything with this spacing in my goodie boxes, the search

for a replacement will now commence....

Bob,

I'll check my stash and if i have anything i will let you know. got the measurements?

[Grandpa]

Since you have all the pieces, it would not be that difficult to cast a new one if you can't find a replacement.

Here is a link to a good gear supplier that sells individual gears.

Thanks for the link, Grandpa...lots of good stuff !!!!

Robert, I'm going to attempt to glue all the pieces

together, I'll let you know the measurements....It

could save me from yet another valiant, but futile

attempt at casting.... :)

[Grandpa]

robobob,

another source for gears are local hobby shops that sell RC cars. from the photo it looks like a standard 9 tooth pinon gear would work. Most of the RC car parts are in metric sizes so you won't have to drill or fill the gear hole.

:) An excellent source for gears is cheap batt op. robots. I have found that the repro smoking robot is a good robot, lots of different metal gears on top and bottom. I try to bid on any non-working examples that show up, I have gotten as amny as five replacement gears and also the shaped eye bulbs from one robot to fix lots of others. If ther is a cheaper way to get metal replacement gears, I am interested in it. -Larry 7

There is! The long suffering remote controlled dogs. They have provided me with

umpteen battery boxes and enough gears and motors to last for the next 50 years.

Generally they do not exceed $10-15.-. There is one main disadvantage. They usually

have a squeak-box that is supposed to represent the barking and when you put a big

cutter into them, so as to reduce them to their essentials/ useful parts,

they squeal lamentably....

I can warmly recommend specially the Poodle with Tartan cover. It yields a motor that

appears in many '50's robots and when you are lucky R-35 eyes. ..+ gears galore!

Grandpa That is a very useful link you provided!! Thanks.

50 years of taking things apart have provided me with lots and lots of little What-not's,

but there are some goodies there!

[larry seven]

:) Excellent! Thanks, H.I. Gosses. Thank heavens that the squeaky box mechanism wasn't used in any robots! I did repair a bump and go saucer toy once that had the steel strings that were plucked to create the space sound. Charming. Is that the sound device of a Chime Trooper? I have never seen one, so I don't know. -Larry 7

[H.I. Gosses]

Now! I've played the chime trooper for your 5 times and you did not react,

ungrateful, truely ungrateful...

CT is a plink-e-tee-plonk mechanism. i.e. steel tongues that are set in a rotating disc

that rolls over a cam.* Sounds like an African thumb-piano. (No doubt the net wil give you

that sound. If you reduce the melody to 4 tones, you have the CT)

*all of this is speculation, 'cos I never opened mine.

Henk- this one? This guy has some wheels on his feet that look like they might work with some larger robots also.

Good luck Bob!

[H.I. Gosses]

Yes indeed. The famous "McDonor-dog" . Surprising as it might seem, these,

inspite of being about 40 years old, can be bought on eBay MIB for as little as

$12.- Generally my postagecosts are about double the purchase price.

It slightly goes against the grain to destroy these toys. For that reason,

I recently tried to sell a few that I had not (-yet-) slaughtered and that were

really pristine in mint boxes. Not a dog would even look at them!

Finneas, start practising the bending of cranks, your parcel is on the way.

The wheels of these dog do indeed fit larger Alps robots a.t.s.

Robobob: Glueing these parts together will get you nowhere.

This is un-glueable. In fact the composition of these materials, Delrin, Makulon etc,

is specially prepared to prevent glueing. - in this case read "glueing"

as seizing up inside a gear train.

They are more expensive than Poly-Ethylene but they would make great

bottles for superglue.....(!)
