Can a #4 frog/point tool for a wye be used for a #4 turnout as well?

-G-,

I've always thought that aa #4 is a #4 and that''s that. Or #6, or #8,etc.

I'm making curved #10 turnouts using a #10 Frog and Point tool for the standard turnout.

Go ahead and give it a shot. It'll work.

Thanks Chuck.

I had a feeling it would work, I just wanted to make sure.

I had been told a "WYE" was half a standard turnout, as it does not have a straight through route, and each half is less then the full amount of the # it labeled as. If that is true then you would need a different point set for a Number 4 wye, as its actualy a number 6 or maybe 8 frog in the middle. Mabye Tim or eccammey could clarify that I know nothing about what I am talking about.

What Kurt says is very likely true.

I guess I don't know that I'm talking about in the case of WYES..

Nope!! It looks like a 4 is a 4 again.

After posting my last reply, I had a thought and went to the Fast Tracks offering for their Turnout and Wye Assembly kits. The Pont form tool in both the turnout and the Wye Kit is a PF-4-M. Check it out for yourself.

Happy building.

The frog angles are the same. Each diverts at a ratio of 1:4 (or 1:X for any corresponding WYE). What makes the WYE more favorable is that each leg of the turnout is diverging. The entire curving separation is divided between the two diverging routes. Thus the closure rail minimum radius of a straight 'normal' turnout is actually about 1.85 times larger when used in a WYE - nearly 'doubling' the effective 'smoothness' of the transition. (It's not exactly doubled because of the lead distance geometry).

Filing the frog (and the points) is the same - it's just the doubled diverging closure separation geometry that makes the WYE so much more useful in accommodating equipment.

I estimate I have about 5 pounds of coupler springs somewhere in the vicinity of my workbench.

emccamey, thanks for setting me straight, or diverged, what ever it is. I knew something was different with wyes.
