I have done a few successful headswaps in the past, but don't do them often and must be forgetting some finer points. The story:
I'm removing IT Gene heads from yellowed Gene bodies and replacing them onto the IT Gene replacement bodies.
No problem removing the heads. (Well, a few knobs MAY have ended up in a few heads, but you gotta break a few eggs, amirite?...)
But I can't get the heads fully onto the new bodies.
To heat the head, I'm using both heating pad & blow dryer. I hold the blow dryer spout about 1-2" away from the hole for about 1 minute.
The knob goes into the head's outer hole fine, but push as I might, the knob doesn't seem to make it through the head's second smaller inner hole, even with a lot of head mashing/squashing.
Did I get the hole too hot?
I realize this is tough to troubleshoot via words, but any help appreciated.
