Does anyone make a 20 ft. diameter/10 ft. Radius switch?
I don't know of any retailers for that size but the switch plans in last year's GR would allow you to make any size switch you want.

Yes, there were plans for #6 switches, but they could be probably be easily modified to your desired size.
I really do not understand the numbering system for switches.
Why don't the just use the radius/diameter of the curve track?
I have the same problem when they use a percent for amount of curve.
I will quote a previous GR mag. article: "...For example, a#5 turnout diverges 1" at a point 5" past the point of the frog. The larger the number, the more gradual the track diverges from the straight track..." and then later on (and I'll sum this up so there is less to read):commercial turnouts are often designed to replace one section of curved track. The divergent track curves smoothly and at the same radii. Prototype switches are normally made so that the divergent track is straight as it goes through the frog. This eliminates side pressure on the wheels and offers less chance of derailment while the wheels are passing through the gap in the rails at the frog. So there you go a lot to write.
Do you mean the degree of curve?
Thank You for the clarification.
Straight to the frog, I would not have guessed.
I am going to attempt to make my own what would be a 0.4 switch.
