Might also try Amazon and see if they have a better price. Splicing 6 AWG to 8 AWG is a bit more of a chore. Check with companies like McMaster/Carr ( mcmaster.com ), Grainger ( grainger.com ), Fastenal ( fastenal.com)or even Amazon.com. I=99m sure one or more of them will have 6 AWG butt splices which can probably be used to connect 6 to 8. Most likely will take a heavy duty crimper though. Another alternative is: http://www.bandc.aero/electrical-terminals-splices.aspx The ring terminals at the bottom for 6 & 8 AWG wire with a suitable short bolt to connect and lots of heavy shrink to cover. Again, this will require a heavy duty crimper of some sort. These are off the top of my head. Others may have better ideas.

The only thing magic about 63/37 (tin/lead) solder is that it transitions directly from solid to liquid states (at 183=C2=B0C) without pa ssing through a plastic state -- a so-called eutectic composition. 60/40 so lder has a slightly higher melting point (186=C2=B0C) and passes through a b rief plastic state between solid and liquid. 60/40 has fractionally lower t ensile strength than 63/37, but for our purposes it makes no difference. Pe rsonally, I buy whichever is cheaper on the day I'm looking.

It's still electronics grade solder. Just keep the joint stable & let it cool naturally (don't blow on it). It will still cool quickly so that's not a big deal. Either will work fine, as long as it's rosin core for electronics work, and not acid core for plumbing. Not likely that you would have gotten plumbing solder at an electronics supply house. BTW, I've enjoyed prowling through your build site. Looking forward to seeing you fly the BD-4C; I owned an old trigear BD-4 for a while & might have kept it if it had been a C model (not available back then).

Just don't let a wet joint wiggle as it crosses the cooling fence between molten and solid . . . an this is exceedingly EASY to do. I wish you'd hollered about needing some solder. Many Listers have designs that will install a few components that use/favor soldered joints. But few OBAM aviation projects will need more than an ounce of solder . . . except if you're installing honking terminals on fat wires . . . then you might need 2-3 ounces of solder. I've got a lifetime supply (residuals from busier soldering days) and I'd be pleased to donate project-sized bits of 'the good stuff' to my reader's project. In any case, 60/40 is what I used for 25 or so years before I had ready access to a more refined product . . . 60/40 is okay.

Any sort of manufactured splicing product will add considerable 'bulk' to the wire. My personal favorite for a trim joint is to strip about 5/8" insulation off both ends to be mated. Fan out the strands on the 6AWG and use a sharp nosed wire cutter to trim out about 1/3 to 1/2 of its strands. Fan the strands on the 8AWG then interleave them into the stands of the larger wire and form the expanded strands back into a tight bundle. You can wrap the interleaved strands with some small wire . . . strip off a chunk of 22AWG to use the bare wires for 'binding' . . . then solder the joint. Cover with shrink when cooled.

There isn't really a 'debate' . . . it's a 'choice' for achieving design goals. Different goals call for different choices. My observations and experience with fast-ons in general aviation dates back to Cessna's incorporation of the Carling Rockers in the 60's. They proved to be an acceptable solution to Cessna's design goals for a satisfactory yet inexpensive alternative to the legacy screw-terminal devices which greatly improved manufacturing labor costs. I began promoting the fast-on switches and fuse-blocks into OBAM aviation about 1990 . . . it took hold and I don't think anyone has looked back. The really cool thing about a fast-on switch is that you can replace it literally by feel alone. No itty-bitty short screw with lock washer and screwdriver slot to thread through a ring terminal that just won't hold still. Without a doubt, the Honeywell products are fine switches that have a history dating back much further than the transition to fast-ons in the single engine market. In terms of MTBF, the Honeywells may well have a greater laboratory service life that the Carling . . . but when the average light aircraft switch gets operated perhaps 200 times a year, is your money well spent to get a switch 'rated' for 30,000 cycles as opposed to 20,000 cycles? Further, if your design is failure tolerant, then the switch replacement is a cost-of-ownership as opposed to a risk issue . . . on that train of thought, the Carlings with fast-ons are way out front.

The wire is 20 AWG in this sample: That joint is probably quite adequate. There are some signs of 'beading' for the molten solder at the interface with the terminal . . . an effect of terminals exposed to the air and moisture for some time . . . solder has difficulty getting an aggressive wetting. The really BIG difference in solders has more to do with flux than the alloy. There are really 'active' fluxes that would produce a more wetted joint but I wouldn't be afraid of what you've produced. One thing you might 'practice' with is a technique I call "flushing" the joint. Put some heat to the terminal as if you were going to 'tin' the end . . . but push some solder into the melt until it drips, then wipe it off with rag before it cools. Some solders I have are very active flux and the excess melt+flux goes a long way to preparing the base metal to accept the soldered wire. You wind up using perhaps 2x to 3x of solder necessary to complete the joint but the act of flushing with some excess melt + flux can be useful to the finished joint on 'stale' surfaces. That's something you can play with but what you've shown us is certainly adequate.
