Nice story. Thanks for confirming my idea that indeed the white ones were the older production and the black ones the newer.

Anyway, I thought hole diameter on the white ones I had at hand with the knurled brass was BIGGER than the black ones, but the story of Drummerboy seems to contracdict this. Can you confirm which of the 2 has the bigger diameter? I don't want to open up my turntables again just for that. ;)

I have an 1300 MK2 with the white part. From reading this thread, can I assume that there is no fix for it using Shapeways?

@kneedeepinit Unfortunately no one has answered my question so I cannot help you either, but you can fix the part drilling small holes in the thicker part and use those to put kevlar (fishing) wire through and wrap it around the part, and finish off with epoxy glue, or you can thake steel or copper wire to go through those holes. Just make sure it is strong and tight. Examples:

with the 1300mk2 you can glue the broken parts onto the brass ring it rides on,then put some lubricant on the bearing the brass ring runs on

The thinnest part of the ring (only 1, max. 2 mm) has to withstand quite a lot of force from the arm. Just glue usually does not hold for a longer time, this has been tried a lot in the past years, but even with the best glues the result was prone to failure. Really, your best bet is to reinforce it first with kevlar or metal wire, and then use glue, as the pictures show. The 3D printed part is also good because the part itself is nicely over-dimensioned and of stronger plastic, so it will hold better.

thats the thing dutch i didnt glue the thin weak part of the assembly,i glued the whole assembly to the brass ring that it moves on so any tension is transferred to the whole ring rather than that daft thin plastic part,its rock solid using decent epoxy,without the problem of drilling anything.

i did rough the whole lot up first with some sandpaper and thoroughly degreased it so maybe thats why its held for so long.

You did a very good job then, because many have tried the glue-only solution and have failed. Hope it will hold well in time. ;)

For those interested, here is a broken / battered black SL1300MK2 cam (with smooth bushing) of mine compared to the white shapeway cam, which fits fine as a replacement. See how the Shapeway version is much thicker at the critical (thin) point where the lever pushes against the part.

So what was the final outcome on the original white type for 1300mk unit. Does this updated one fit both black and white original cam?

It does fit my black ones! I replaced 2 already. Versions with smooth bushing + black cam.

One on a Silver "Technics" model (International version, SL-1300mk2, and one a Black "National Technics" model (European version, SL-1310mk2). I do have another European SL-1310mk2 though with a knurled bushing and white cam, but on that one I just repaired the cam myself with a drill and some iron wire. So I did not try the 3D printed part on that one. ;)

Hello,
Though I am not completely new in this forum, this is my first post here.
First of all a big thank you to the man, who made it possible, to order this great spare part at shapeways. I ordered one an was able to fix one of my SL-1410 MK2.
Unfortunately I have two more SL-1310 and another SL-1410 with the original white part, where the shapeways part does not work.
To be at least able to find out, if a system has the black or the white part without disassembling, I startend a little experiment and wrote down the serial number, the full model name (SL-1410 MK2A XG) and which cam lever (black/white).
Until now I have the data of five systems, but it is not yet possible to come to a result.
I would like to invite everybody to join my little experiment and send me the data of his system. Of course in return I will share my little database with everybody who participates.
Cheers
Chris
