Hi everyone,
Before laying the main on my railroad I soldered 2 lengths of flex track together hopeing there would be no kink where the 2 lengths meet. However that is not the case. The track has a small kink there that derails some of my locomotive and derail my desire to do more work on the railroad. I am using Atlas code 100 flex track on an 11 inch radius curve if it makes a difference. Here is a picture of the kink causing the problem. Any and all help is welcome.
Thanks
Sean
Even when you solder the joint, you want to do everything you can to keep the pressure off of it. Since it looks like you used track nails to hold it down, you might try adding one in the hole nearest the joint. But before you do that, you can try to get the kink out. I'm assuming that there is solder in the joiners under all of the rails. Get something to push on the joint, and a hot soldering iron. Warm up the joint, push the kink out, remove the heat, and wait a couple seconds before removing the pressure. Then do the other rail.
When you do the joints initiallt you need to make sure the solder has well and truly flowed into the joiner and around the rails. And you need everything to be as snug as possible. That's a tight curve, so you'll need to be gentle as you bend it, and give it as much support as possible.

Did you originaly choose the wrong photo?
I recieved a e-mail with a pic of Sherman tank, and while they have tracks I couldn't match pic to words
I always lay my (Atlas N scale code 80) track first to make sure it lines up correctly. Then I do the soldering, and remove any exsess solder on the inside of of the joint then file it smooth.

This is HO, but same concept:Notice two ties are holding the rails together between the joint. These are not "fake" ties stuck under the rail ties.
It's been a while since I laid the track on my N-scale layout, but here's what I remember doing. Set up the flex-track so that the movable rail is on the inside of the curve. Try to avoid joining flex-track in the middle of a curve, but that's not always possible. Establish your curve, and in those cases where the joints meet in the middle of a curve, let the flex-track go straight and then solder the joints. After the solder takes, it can be put back into place and secured.

Right, I forgot this point. Put in the curve, and remove the ties where the joint is when it is curved. That way you avoid the larger stretch of removed ties.
When joining two pieces of flex track, I prefer to trim the rail clamps from one tie at the end of the flex track section where the rail joiner will sit, rather than cutting the ties out, then joining and soldering. I find this helps maintain the gage and looks better (to me) than gluing the ties back in later.
As MAbruce mentioned above, the movable rail should be to the inside of the curve. I then place the track and for the curve, letting the movable rail extend at both ends. Once the curve is established, I trim the extended inner rail to meet the next section.
From looking at the picture you included with your post, it appears you removed the tie clamps from several ties. This may have caused your problem. It also appears that you might have placed the power lead after the track was pinned down. I prefer to place power leads away from the rail joiners to prevent reheating them and allowing the track to move as a result.
Hi!
As I look at the picture, it seems that the track joint is closer to the outside of the roadbed, then flexes back towrds the inside of the road bed as if though iif the jointed section needs to be moved slighlty inward.
Joe Fugate has an EXCELLENT VIDEO about laying flex track, downloadable through MRR .
I HIGHLY RECOMMEND purcasing it, and downloading it. It's about 5 or 6 dollars but worth it.Next, what you want to do is to lay your TWO pieces of FLEX TRACK out straight, REMOVE about 2 TIES from the end of each one, then join your track so both rails are even, slide on your track joiners, THEN SOLDER them together, THEN lay your track on your curve, and carefully watching for kinks.
If you aleady have ONE PIECE of FLEXTRACK layed down in place with the radius curve alreay established, follow the above procedure as far as removing two ties at both ends where they will meet. THEN gently bend your track to the desired radius, and THEN marking your track as one rail will be able to slde(make sure it is on the iNSIDE of the radius curve), then cut your rails so they match up with both rails squared and even to each other, then slide on your joiners, and and use pins or tacks to hold your SECOND piece of rail in place, THEN SOLDER it.
THEN replace the ties you cut out,( I use wooden replacement ties that I dye black first) and I use CA glue or very small amounts of 5 minute epoxy to reattach the rails to the ties, and place a weight of some kind over them until the glue sets.
Suggestion-I ONLY SOLDER on the outside of my rails, as any solder on the inside can interfere with wheels later on.
If you use a soldering iron, wait until it is HOT enough to solder, then touch it and your solder to the work piece for 5 seconds, then pull away, and allow the joint to cool.
Hopefully you will have better luck.
This is what I learned from Joe Fugates video on flex track.

Thanks everyone,
I was able to improve the situation by desoldering the joint and pressing them straight with a flat blade screwdriver. Finally, I installed additional track spikes on the joints to help brace them straight. Thanks again to everyone who replied all of our advice was greaty appericated.
