QUOTE: "So all this talk about the battery spring got me to do a little mod on the axis.
Here's what I did, I used a diamond bit in my Dremel clone and ground out the first 2 1/2 threads out of the axis so those 3 coils that still stick out can collapse into the axis giving it the same connection as if there were no spring at all while still maintaining some tension on the battery so it doesn't become loose as easily. I've been thinking about for awhile now, I'll see how it goes before doing it to my other one"
Well I was so pleased with how well this simple modification worked that I applied it to my other MKB
