Originally posted by michealfarley The advantage to powering the frog is for locomotives with short wheelbases.

Powering the frog with the correct polarity to match the route insures continuous movement by even the smallest locomotive. You must have some sort of switch that changes the polarity of the frog with the movement of the points. Understand, thanks. I run P2K SW9's over Atlas #505 and #506 switches all day and they never give me any problems at all. I was just wondering.

That has worked very well.

Then I solder a feeder wire to the brass screw. I use these switches in staging yards only, so I insert the screw from the top. This would still work well, as Michael stated, if the screw was inserted from the bottom.

Using a small screw or nail down through the hole to pressure-fit the wire is the simplest solution. Reply michealfarley Member sinceApril 2003 From: Fargo, ND 136 posts Posted by michealfarley on Friday, August 27, 2004 6:23 PM Tap the frog hole for a 2-56 screw, and install a metal screw with the wire attached up from the bottom. Cut-off the portion of the screw above the frog and file smooth. My dad powered tons of Atlas frogs this way and never had a problem.

Posted by Anonymous on Friday, August 27, 2004 5:13 PM I thought I would take the easy step of powering up some Atlas #6 frogs and amy stymied by not being able to solder to them. I am trying to solder to the bottom of the round (screw hole?) wing on the frog. I have tried scraping it with a screwdriver and even cuting into it (from the bottom) with a knife. The solder simply will not stick. What am I missing here? Any other ways of attaching a feeder wire?
