Victor RCA windup suitcase tone arm is sticking

[NippersMaster]

Hi - I'm a newbie to the forum and hoping I just haven't found similar posts already (likely).
I have a circa 1930 suitcase model marked RCA on the record holder in the lid (spring-wound, not electric). Assuming it is from the crossover period to electric. It's in fantastic condition with bakelite turntable accents, etc. Trouble is the tone arm mounting sleeve is permanently riveted to the turntable platform - I cannot remove it. The arm is sticking enough at this point that it causes the needle to stop and makes any record skip. I initially tried a little WD 40, then some 3-in-1 Oil to no avail. Now I'm wondering if that was the wrong thing. There is barely room to access between the areas - is graphite powder a better plan? Would it possibly have had some factory seal that has worn out (doubtful, the space is so thin). Because I can't access inside the arm, I can't see if there was a suspension device that may have alleviated some of the pressure originally (like some larger models have). And, if so, I would have to tear the thing apart to attempt it. Thought I should consult some pros, first.

I hesitate to answer your question with so little info on your machine. If you could post a photo or find the model number this forum could provide more help. Being who I am tho, I am going to guess you have a 1930's RCA Model 0-10. The 0-10 is made by Boetsch Bros. (Birch phono Co.) of New Rochelle NY. They used pot metal on both the tone arm and surrounding collar. Pot metal swelling is common and restricts tone arm swing causing groove skip. Or causes complete seizure of both parts.

As for repairs I would reccomend you post the model # and a picture so as to receive the correct repair techniques
