It’s not really about being a critic….it’s about monitoring the type of info that gets put forth on the forum and being responsible about it.
Some folks might take it as gospel that it’s a good idea or perfectly safe just because they read it on here.
I've typed responses to this twice, and didn't post them because I didn't want to ruffle any feathers by being too critical.
There are some errors in the video, and some of it's just dangerous. I don't blow torch wood in my garage. A few months ago, I watched the neighbor's garage burn down, along with his vintage vette. $hit can and does happen, and I keep things as safe as I can.
Having said that, another error was the assumption that "electrical solder" is flux cored. It can be, but many of us aviation electricians never used the stuff, opting for a tin of paste (resin only to minimize corrosion) and solid core solder with a 60/40 lead/tin ratio, not pure lead as he did in the video.
Also, instead of digging through grandpa's garage for pure lead solder, (some of us here are grandpa's) it's far simpler to hit the sporting goods section and buy some split shot fishing weights.
If doing Mikuni ends, it's easier and better to get some brass tube (I forgot the diameter I used) and solder the cable to it. Note above when I mentioned resin flux for electrical connections, acid flux (used for plumbing) is better.
The purpose of the flux of course is to etch the metal. I don't know why he filled the wood hole with the flux in the video, unless he was concerned about flow.
He mentioned silver solder too. It's available in several different metal ratios and the melt temps vary accordingly. A butane torch is not adequate for some of it, however a propane torch with it's 3000 degrees works.
The video was interesting, and informative and provides alternative methods for doing up throttle cables, but I'll stick with my own crappy methods, and hopefully not burn any wood, garage, house, or Dodge RT's, or mini bikes in my garage.
