Hi Guys,
Does anyone know if the hinges for the MCP 5500 are still available with B&O dealers? If not, has anyone come up with a decent alternative for when they break beyond repair?
Thanks!
Ben
They are no longer on the B&O database and no longer available along with those for the MCP6500 which were slightly larger.
They were deleted around 3 years ago IIRC
Regards Graham
I tried several attempts to fix this horrible hinge but no luck. The guy who designed this should be fired.

Mechanically it's a very clever invention, but the implementation and materials leave room for improvement...
I bought a pair of 6500 hinges from a dealer in early 2008 and shortly thereafter everybody on the forum was saying they are not available anymore. I'm pretty sure all warehouse corners have been evacuated of them for a long time now, even more so for the older 5500 hinges.

If someone could post a pic with dimensions I will see if I can make some, checked the spare parts list, but cant see details there, I have a MCP 5000, is that the same hinge ?
Collecting Vintage B&O is not a hobby, its a lifestyle.
Anyone have access to a 3-dimensional xerox machine? Piece of cake, including the hinge operation.

Orava has access I think, he mentioned something in one thread
If anyone wants to send me the part (even a broken one) I can model it and have it printed. A friend of mine has a 3D printer. Or if its simple enough, I could use manual machinery and make a metal one.
I did this last year for another BeoWorlder with great success.
EDIT: Soren, I would like to be the first to congratulate you on your P4K!

Be aware that the parts are tiny and I don't think any prosumer level 3D printer will get near the required precision without very tedious hand finishing. ABS or PLA plastics they use would probably break the first time the user forgets that the hinges are made of ABS or PLA plastic.
I'd be glad to be proven wrong, though! The original gears are plastic too, and that's why the hinges start to sag (after some of the teeth are gone).
I'm not sure if I still have my original 6500 hinges or if I've already donated them to somebody, but I'll keep this in mind if they resurface somewhere.

I'm especially thinking of Beocenter 5000/7000/7002/7007/7700 right hand side ant hinges for CDX.
//Bo.A long list...

Thanks Ev, nice to see you again here.
As I have a MCP 6500 whit the same problems but otherwise okay here is what Dillen told me:
The MCP5000 is different than the 5500/6500 and 7000.
My option is to get a 5500/6500/7000 to take the hinges from unless I come across a loose pair.

Thank you Anders, I was about to take my MCP 5000 apart, now could someone post pics with dimensions so Evan or I can get to work.

Good point Mika. A regular FDM print may not be able to resolve such intricate geometry.
Since the parts are so small, SLA printing is affordable for this scope of project. SLA prints are also very durable.
We could even upload the solid model to Shapeways and have it metal sintered!
At any rate, let me know if you can provide specimens and I will CAD them up.

Anything, anytime! Let me know what I can do to help solve an age-old BeoProblem and I will get to it.
If anyone reading this thread is reminded of a problem similar to this (broken, irreplaceable plastic parts) please feel free to contact me.
Søren Mexico:Thanks Ev, nice to see you again here.
No problem, Soren. I'm really trying to get back into this. I think I'm going to make it my New Years resolution!
Evan:Anything, anytime! Let me know what I can do to help solve an age-old BeoProblem and I will get to it.
I'll see if I can make a CAD model of the 7700 hinge.

Excellent. If you think this can be made via conventional ABS extrusion (FDM) printing, be sure to make part thicknesses in intervals of 0.016" or 0.4mm. This is the diameter of the ABS stream. If you need more clarification on this just let me know. This will be built on the build plate broad side down. When you are done, export as a STEP file.
Hi Evan and Soren,
sorry for taking a while to respond!
I have attached pictures of the metal part of the hinges. They were taken on my iPhone so are not fantastic, but I can provide measurements too. The plastic teeth on my hinges has completely perished. But you can see how fragile and small the parts are. I have tried to include the measurements which you might need, but let me know if you need anything else. If anyone has an actual full hinge including the plastic bit, that would probably more useful!
The metal parts are not the issue, it's the plastic part. Hats off if you succeed but I have my doubts!
It can all be made in steel or aluminum, but lets see if Evan can make something in plastic, I am very interested in 3D printing
These are NOS.There are two plastic parts, they mate together as a gear.Quite delicate parts.

3D printing in metal exists; just not for home use..
I was reading up about it some 6 months ago, and yes it does exist but still in the developing phase, same with the plastic printers, still a lot to be done before its perfect.
http://www.cnn.com/2013/11/08/tech/innovation/3d-printed-metal-gun/
"(CNN) -- A Texas company says it has made the first metal gun using a 3-D printer, taking the debate over people's emerging ability to create their own firearms to a new level.
Solid Concepts, a specialty manufacturing company, said in a blog post it has fired more than 50 rounds from the handgun, even hitting a few bull's-eyes at more than 30 yards."
Scary..
Leslie: The metal parts are not the issue, it's the plastic part. Hats off if you succeed but I have my doubts!
The metal pins will have to be re-inserted into the part (if I'm reading the pictures correctly) which could add a slight hitch. Hopefully it all just presses together.
I really enjoy challenges Leslie, I hope I can fix this. I have never held or used an MCP before and personally, I don't have an affinity for them (yet!), but I know for those that do, this will be a giant leap forward in longevity and enjoyment.

Martin,
If you are comfortable, do you think I could have the chance to make a reference CAD model from these examples?
If not, I understand - they look absolutely PRISTINE.
My second choice would be to request a broken set.
Thirdly, I could always correspond if you are comfortable taking measurements.
Let me know what you think and/if/how you can proceed.
Evan:The metal pins will have to be re-inserted into the part (if I'm reading the pictures correctly) which could add a slight hitch. Hopefully it all just presses together.
B&O uses a lot of pins pressed into plastic in their constructions, lids, even gears pressed on steel shafts, on these hinge we are probably down to 1 mm pins, if they are pressed in, the hole would have to be something like 0.95 mm, but 1 mm will do and a small dot of crazy glue or epoxy will do.

A believer - thanks Bob!
Now I have to make sure this is a success! To me this is where the spirit of BeoWorld is - collaborative problem solving. It can be done.

Even if it can't be done you'd still get an A+ for effort & passion.
Anyone know why this thread suddenly died?
6 years on, hopefully 3D printing technology has moved on to make this possible?
I only need 4 new pairs of hinges!
Cheers
