Working on the 2 End Loop Modules - Part 6

First on the agenda is the "brown" paint you may have noticed in the 2nd to the last photo in the prior Post.  

After the ties for the turnout are in place but before any rail work is done, the 2 longer ties where the mechanism to operate the turnout is connected, are painted with the same paint as the balance of the track will be painted. It's hard to paint in this area after the rails and mechanism is installed. More about the paint and painting when the balance of the rail and roadbed is painted.

Next - Yes, a turnout and a crossing with curved frogs are to be built. Extremely important items to point out are the Golden Rules of turnout and crossing/track scratch building -

Whenever building a turnout or a crossing with a curve through the turnout frog or the rail crossing, always used a continuous curved piece of curved rail in building them. For the straight track, individual pieces of straight rail are cut to fit in where needed.

Also, do not have any rail joints with connectors in either the curved or straight track. If the piece of rail being used is too short, replace it with a longer piece of rail!

With this thought in mind, the next piece of rail to put into place is the other curved piece of rail. This piece of rail ends with a tapered piece of rail called a point. My piece of rail will end with a rail connector. The curved point will be fitted into the rail connector later.


A reason for not using the Old Pullman prebuilt #3 frog turnout is, it is to be used to measure parts of the prebuilt turnout. The length of the points can be measured and copied which is what I did.

As work was being done installing the rail to make the curved track, run a non-powered car or at least a single truck over the track and around the curve(s). Correct any problems before proceeding further. The most common problem is the gauge of the track and any guard rails is too wide or too narrow.

Do not use or operate any models under power until all the soldering flux as well as the rail is cleaned. Soldering flux will cause the rusting of ferrous and chemical oxidation of non-ferrous metals. The chemicals in the flux will expedite problems with your models.

After the curved track is done now install the straight track up to both sides of the crossing. Install straight up to the far side of the turnout.

Install the 2 pieces of straight rail between the curved rails of the crossing. The curved rails can be cut just a little bit (head only) to make the frogs. I used a small diameter cut off wheel for this operating at a low rpm.

The guard rails are installed one at a time. Pre-curved rail with the same radius must be used for the curved guard rail.

Remember, you're suppose to be making the turnout from the instructions found on YouTube. If the web instructions don't cover a curved frog, make the frog just like the track work for the curved crossing.

When the guard rails are in place cut the rails deeper as required per NMRA Standards. Besides the small cut off wheel in a Dremel Tool a broken hacksaw blade can be used. The knerf of the blade works out well to make a wide cut. The blade can be slow but will not cut into the rail a fast as to damage your work. I have permanently curved pieces of hacksaw blades for this use.

Place the turnout points in place but do not finish installing them. Check the rails of the turnouts to see if any further adjustments are required, Make corrections now. Remove the points and store them.



You'll have to wait for the next Post to find out the color of paint used.

Cheers,
Ed
