So, I dun goofed.
One of the halves of my favorite yoyos stripped today. I have an idea of what caused it, and hopefully some knowledgeable members will reply and confirm my suspicion.
So, one day the axle side with the allen slot got stuck in one half of the yoyo, and to avoid damaging the threads, I thought I would try wrapping the exposed axle with teflon tape, screwing the yoyo back together, then unscrewing it with the allen slot exposed. It worked!
Looking back at this, I think that I used way too much teflon tape. 6-7 wraps, at least. The first time screwing the yoyo back together after the teflon tape was applied was difficult, and took some effort. Could I have damaged the (female) threads enough here that they were on the verge of stripping?
The yoyo was made of 6016 aluminium.
PS: I don’t feel like mentioning the yoyo in question here is important. Talking about how a yoyo stripped tends to discredit the yoyo, when this was probably my fault.
