I am also the owner of 1410mk2 and infamous part which is broken :(
I see that some people have already ordered 3D print (SDG0407 great CAD work by the way! Thanks).
Does it work? I mean if plastic is hard enough to last years and flexible enough at the same time so it won't crack?
Is it possible to order it only from US?

I purchased the part and it's real nice.
For the life of me I cannot get the cueing to work, or any tonearm action for that matter.
After the 6th dis/reassembly I managed to break a couple of the tiny tonearm wires.
I've since decided to just button it back up (after fixing said wires) and use it as a manual before doing any other damage.
I know some have gotten it to work, but so far I am unsuccessful.

Mine is still going strong after a year of almost daily playtime on my 1400 mk2.
I ll update when mine breaks.

What do you mean with order only from the US? I don't understand.

I ment shapeways.com is from US. I do not know if will have to pay any additional tax. Olso, overseas shipping is more expensive and I am a poor man. Never mind though. I have ordered the part today.
Will share my opinion a.s.a.p

Besides the US HQ's, Shapeways is also in the Netherlands. Actually its founder is Dutch, and they started in the Netherlands. The customer service is a Dutch number (+31), the paypal payment states that Shapeways is outside the US, my item arrived 1 day after it was shipped, so in my case it was shipped from the Netherlands.

By the way this cueing part also works on the SL-1300/1310 MK2 models. I notice however it's a bit less smooth: sometimes after powering up the 1300 from a cold start, I have to press the start button twice because the first time it doesn't manage to lift the arm, it just shuts off again after a few seconds (platter stops spinning). But the second time pressing start it always works. Also, after that it keeps working the first time i press start, until I power off the turntable and start using it again after one or more days. I suspect it is because the long "handle" on the part is also a bit thicker than the original, making the automatic mechanism having to work a little harder.\

By the way: both my 1300mk2's had the black part (broken), and my SL1310mk2 had the white part (also broken). If I can still find them I will have a look to see if there are any significant differences.

Dutchflea, I'm gonna try this. I have a SL 1500 MK2 with the cueing problem. Which How-To did you use to repair your SL 1300 MK2?

My own: I have opened my SL1300 MK2 a zillion times already. ;)

But here is a pretty nice German guide, since you are Dutch too I think you will be able to handle that.

http://www.spacereh.de/sonstige/Technic ... aratur.pdf

Just don't follow the tonearm wiring instructions, they are soldered in the wrong order in that guide. Just remember the order of your own tone arm before unsoldering. I do not even unsolder but work carefully, taking care not to strain the wiring. But you have to work careful for that.

By the way, the existing part can also be repaired with kevlar fishing wire (or thin steel wire) and epoxy glue. You just need to drill some small holes to run the wire through, to prevent the wire getting in the way of the cueing mechanism. But this 3D printed part works well too, and it's a lot easier! ;)

Thanx Dutchflea. I will order the 3D printed part. Nice job for the long winter evenings. I'll keep you posted.

Good luck. Please check first if your bushing inside the armlift part is the smooth one with the small groove in the middle, used with the hard plastic black cueing part. The 3D printed part in this thread was designed for this kind of bushing. The other version of the busing has a knurled outer edge and is used together with the white nylon cueing part. The bushed ring on the white part is slightly wider, so the 3D printed part will not fit unless you widen the ring a bit by filing off a little. I have both parts, so I know from first hand.

My three silver SL1300MK2's (2 European, 1 US) had the BLACK part with smooth bushing. They also have nylon parts for the muting switch frame and the little arm wiring guide.
My one black SL1310MK2 (European) had the WHITE part with knurled bushing. It has metal parts for the muting switch frame and the little arm wiring guide.

I am not sure which version was there first, I suspect the black part came after the white nylon part, but the fact is that it was Matsushita's failed attempt to fix the problem: they both kept breaking. ;)

Hello All, I just wanted to share with everyone here that the new Cueing lever that I ordered from Shapeway doesn't work.

I ordered this part about a little over a month back and just got around to installing it. Well, some how Shapeway messed up or didn't read the new specs/dimensions correctly but my part didn't fit. The center hole was too big for the knarled brass looking ring to fit. So now I have a table all torn apart unable to fix. I will try to either fix the new part via some small screws or just junk the table and part it out.

I will first try to see if I can use the Drive system for a DIY project with a way better arm and a new better base for the drive system which the drive system is a better one that the SL-1200MKII. Don't know if I can since its a automatic circuitry but if I can disable it while still be able to keep the drive stable and accurate then I will go the project route.

Please be careful when ordering this part.

The 3D print design was made for the version with the black plastic part and the smooth ring, as can be read in the opening posts My ordered part fitted perfectly snug on this ring.

There is also a version with a white nylon part with a knurled ring with different diameter. I know this because I have had/repaired both parts/rings. I thought the diameter of the knurled ring version was bigger but I am not sure. Your experience seems to contradict this, or Shapeways really messed up. Just measure the diameter of your 3D printed part and ask the topic starter if these are the correct dimensions for his design.

By the way, I think the white part with knurled ring came with an older version because the turntables I had this part on (SL1310MK2's) still had the "National" logo left from the "Technics" logo on the front panel. Also it has metal parts for the muting switch frame and the little arm wiring guide, where the other version has nylon parts there.

Hi:

I contacted shapeways with questions about the lever. Does my SL-1300 MK2 have a bushing on the broken cam lever that I can re use. If so what is the proper way to install it?

Or what size bushing do I need and where to get one?

This is very cool, as I've had multiple requests over the years to repair MK2s, only to turn people away after finding that the plastic armature had been removed years earlier. We did have some of the NOS back in the last 90's, but they of course got used up. We came up with a fix some time ago, and it's held up quite well (never had a return because it broke again) but we wanted to have the part made again. Looked into it, and depending on the source, the cost was $5k-10k just for the tooling. This part is incredibly complex to mold, and we always questioned the need for the bearing, which we determined was one of the reasons this part broke. I think the original white parts were made of nylon6, and that does have a habit of swelling from humidity, and then the bearing itself will expand and contract with temperature. The small wall thickness was due to something passing right next to the armature. The difference in bearings (some are knurled brass, others are blackened steel) is usually just depending on the time when they were made. There are two or three designs of the armature, Technics was trying to fix them during production. The later black plastic broke faster than the original white ones. I think the knurling was removed as it's known as a way for cracks to propagate in the plastic, which didn't solve the problem either. I'm gonna have to look into this more, because I've got several nice units that just need the cue armature to be complete. Thanks for the work :)
