I have built HO Code 100 #8 turnouts and a couple of double-slip turnouts using their jigs and method. I have not yet seen an adverse report by users on this forum. A benefit to their use is that you at the same time learn how to make pretty much any configuration of turnout and can lay them yourself when you have unique requirements...I have done that in two locations on my layout.
The turnouts are superior from the standpoint of the frogs. The throwbar and points assemblies are a bit tricky at first, but once you learn how to file down the foot of the stock rails adjacent to the points, and to solder the thin points to the PCB board ties, these turnouts are simply amazing.
One other tip: Tim Warris, in his video, suggests using a jeweler's saw to cut the gaps in four places around the frog to isolate it. I agree completely now that I have used both the cut-off disks and a Dremel-like tool and the jeweler's saw. The latter leaves a gap that is about 1/5 as wide, and much much tidier than the cut-off disk.

Ditto to this. The difference is huge. Here is a double crossover I built, N scale. It gets really tight soldering in the frog areas, but it looks really good.
Jeff But it's a dry heat!
Thanks! I'm sure you noticed with your doubleslips how much more work is involved in this type of trackwork. The number of frogs in a small space gets to be incredible. I've got a doubleslip in my trackplan that I plan to handlay without the jig, since there will only be one. I didn't have to have it, but I sort of want to prove I can do it!

Oh, I did. I simply haaaaaddd tuh!
I think the crew of that T1 is in a bit of trouble for pulling past the fouling point there.

As yardmaster, I'm on my way over there right now.
They make it easy to build really good quality turnouts. I find it takes anywhere from 45 minutes to an hour to do the basic assembly. The nice thing is that you can make the rails any length you want, making it easier to customize things as needed.
Even your first attempt will turn out pretty good.
I would recommend a good soldering iron, light gauge solder, and rosin flux. With a little practice you'll be able to solder things very nicely.
A useful tool is a little benchtop belt sander to grind down the rails where the points meet. Speeds up the process and does a great job. Plus a new file.

I thought I recalled from the video on the Fasttracks website that they recc. using acid flux, then make sure you wash off the flux after the soldering. As I recall, the point is that you get a deeper cleansing of the surface that will hold the solder better. Your experience here? Thanks.

Acid is just bad for anything electrical. It will eat away at the connection, no matter how hard you try you'll never get all of it.
The only real advantage of acid flux is that it's more agressive than rosin. But rosin, while messy, is neutral, so you don't have to worry about the stuff you miss while cleaning. Alcohol seems to dissolve it.
I prep the PCB ties with a brass brush in a Dremel, just a quick buff. Or some fine sandpaper will work too. I cut the gaps with a Dremel too.
For soldering I use rosin core (because I have lots of it...) with a little liquid rosin flux applied to the joints. The other half of the equation is a Weller soldering station with a chisel tip, dialed in to be hot. Like 700F. With that and the additional flux, a small amount of solder will wick into the joint real quick.
The flux is there to facilitate the alloying process. Rosin flux is no worse than acid flux, and a little extra really makes a difference.
The only advantage of acid flux is "easy to find". Most hardware stores will have it in their plumbing dept. OTOH, most manufacturers of soldering equipment recommend you don't use it, because it will hasten the erosion of the tip by a large amount. The soldering process will erode the tip, but acid flux speeds it up a lot. It'll eat the iron plating off the tip.
PS: if you use a damp sponge to clean the tip, it's better to use distilled water to wet it. I prefer to use a rag or paper towel, or one of those bowls of brass turnings.

"Never" would mean that brass locomotives would remain forever hazardous to our layouts, impossible to install DC or DCC electronics. I did not pay alot of attention in Chemistry, but understanding PH was one of those subjects I did seem to grasp.
I tried soldering with rosin and acid on a turnout yesterday. Thanks but I'll stick with Tim's advice, when my Fast Track kits arrive next week.

Nice work, Jeff!!!
I have a code 83 #6 jig, and it works as well with code 70 (the base of the rail is narrower on code 70 ME rail by .001 inch), from what I read on the fast tracks website (they should know!) I've built several turouts, and they FAR outperform any of the commercial ones I've used, in terms of how smooth the rolling stock crosses the turnouts.

True, we in the electronics industry use and recommend non-corrosive fluxes for soldering electrical components.
However, Betamax, your lecture in regard to Fast Tracks is flacid, in that the use of soldering for building a turnout is not to facilitate electrical connectivity, but to assure maximum mechanical strength. The turnout is not considered an electrical component until after it is assembled and properly washed.
For a clear example, I'd NEVER recommend soldering feeders to track using acid flux. The purpose of solder in that circumstance is to facilitate electrical connectivity, not mechanical strength; the acid would attack the insulation of the wire as it wicked inside the insulation jacket where washes would be ineffective and perhaps 'never' be capable of rendering the acid neutral resulting in feeders that might eventually look like little corroded battery cables.
Tim's recommendation to use acid flux is well founded, based upon not only his experience, but a solid understanding of the requirements of his product and the desired outcomes of his customers.
By the way, Tim also recommends and sells a pointed tip, not a chiseled tip. The most meticulous prep does not eliminate the need for flux.
I'll stick with Tim's advice on how to build a Fast Tracks turnout. His expertise is built upon experience and solid science.
