1. Hmmmm, never considered that. What's the supposed advantage?
The poster claimed using a secondary metal might defeat the purpose of the all copper to copper connection, then cited some articles like this
about dielectric grease's impact (or lack thereof) on conductivity. Frankly, I'm not concerned given the popularity of soldering and the lack of issues people seem to have with it.
2. I can't say I've tried going around a radius thaa small, but imagine it could be done with Veneer softener and tight grain species like cherry and perhaps others. I wouldn't introduce a bunch of moisture in any case as it will most likely surprise you when in dries out. You could also cap ends with, say, 1/4" hardwood, then veneer, then roundover. Something that small would be hard to see the transition as long as color is close.
I'll attempt to use veneer softener and see how that goes. I'm using a paper-backed madrone burl veneer, not sure how that compares to tight grained species. I'm assuming the knotty nature of burl makes it more difficult to work with. Adding hardwood is a good solution, but is more work than I'd like to put in if I don't have to, especially given my experience level. We'll see how the softener works on a small scale first.
3. I'd screw it or at the very least use velcro. Foam on back, or some kind of standoff would also do the trick.
Good point, I can just attach some no-res to the bottom of the board and glue or velcro that to the base.
4. Most, if not all, common striper/crimpers I've seen have two as standard fare. One with a titty, as Danny describes it, and one without. Use the with, it's more fun and works better.
I'm planning to get this crimping/stripping tool
. I assume these will be capable of everything I need for the tube connectors and assembling the DIY speaker cables. I asked about size because the same commenter who made the comment about the grease also said Danny should be using a larger crimping tool, one that covers more of the length of the crimping end of the tube connector for a better seal.
