Another option is to skip the springs and the problems they have with being left compressed, and add a garter. I have mine on the outside of the chop so no morticing involved.
I did this back in 2011 and since have realized some problems with my design of the B-O-B. Were I to make another it would be copied from Derek's beautiful design, but with garters.

Thanks for the idea. By the time you posted, I had already bought and installed the springs (didn’t realize there was a McMaster Carr minutes from where I work, so I was able to skip the shipping)
But if I run in to problems or worn out springs down the road, I’ll give this a thought.
