Fixed cueing arm lift for Technics SL 1300-1400-1500 mk2

[SDG0407]

Hi,

I wanna share something that might interest some owners of Technics SL 1300-1400-1500 mk 2 series turntable.
I recently bought a Technics SL 1400 mk2 to find out that it had the know cueing/arm lift problem. After disassembly i measured and 3D scanned the broken part and made a 3D model of it to be 3D printed in plastic.
The 3D model is not 1 tot 1 of the original since I changed some dimensions in order to strengthen it (I don't want it breaking again).

Here you can see the original part:


Here is the new 3D printed one:


Here is the video of the result.
It has now been holding up for several months and regular playing time.

Also when you disassemble the tonearm beware. The little pin and spring holding the VTA adjustment knob sits in this hole. It is easily lost and can be confussing if you don't know what it is or where it goes:


For those interested i put the 3D part for sale at Shapeways so you can order it from them:

Bravo!
This is good news for owners of those models... Gotta lova 3D printing.

I uploaded it on shapeways (where i printed mine) so you can directly get it from them. The link to order it from them is in my precious post.

Also when you install the steel bushing into the new part make sure it is in the right orientation because the press fitting internal ring is not in the middle of the hole. BE SURE TO DO IT CORRECT because you can only fit it once since it is a tight fit.

Thanks for doing this, I've been looking at a friend's sl1400mkII, has this issue. I may be tempted to buy it now, as well as consider these models which are typically priced in the affordable range.

i notice you say steel bushing. the bushings from the 2 1300mk2 i have are brass with a knurled outer edge. was your bushing knurled also?

Mine didn't have a knurled outer edge. It is all smooth with a groove in the middle.
I have heard this comment on another forum as well. Is it possible to post a photo of the bushing you have? This way i can see how it looks and maybe make a variant for this one.

here's a pic both front and back of two of mine with brass bushings

The bushings are definitely different from mine.
Are both plastic pieces broken?
If so is it possible for you to dissassemble them and measure the bushings (diameter, knurls, etc)?
I also noticed the plastic piece is different from mine. There seems to be an extra cam and hole on the plastic piece.

If you send me measurements from your piece i can modify my model for this variant and make it available too.

they are broken at the typical location. but are glued back together. so i cant measure. i tried various epoxy and none would stick very well. one i used jb weld on and has see a medium amount of use and is still going strong for now, i expect it will fail at some point. these two are glued using super glue which seem to form a good bond. after i fix and assemble the arm i'm working on now i'll switch it for the one in use now and maybe it will pop apart for measurement. the extra cam part i don't think does anything but i'll investigate.

Awesome! Thank you so much for doing this. I just ordered mine.

I'm just now digging into my 1300 mk2, but I see from previous posts that it will more than likely be different from the model you have posted. Did you ever receive measurements for the 1300? Would you still be willing to make the changes?

I havent received measurements for the 1300 mk2.
I am still willing to make a model for the 1300 if somebody can provide me with the measurements.

Finally got the cam out of my 1300 mk2.
Sure does look identical to what you've posted and the model you've made SDG!
I will take a few measurements I guess...just to make sure.
*will post photos tonight, said images were too big*

Here's my 1300 mk2 cam!

Here's my 1300 mk2 cam!

I checked the pictures but i can't discern any difference with my model.
My cam was also black plastic and looked exactly the same.

At shapeways they show a 3d view of my model:

You can check your cam with the 3d view and see if there is a difference.
At present i don't see any.
