Intending to lay Unitrack N gauge and use 315mm radius as the largest curve. There will be a double track section and on the curves I will use the 282mm curve on the inside.From one track to other I want to use #6 turnouts.But 2 say#6 LH wouldn't give the correct track centre. What is the answer to this? Hope you can understand my problem - no hobby shop within 400 miles to me

The #4 turnout (20-220/1)

The #4 turnout (20-220/1) keeps the proper 33mm spacing for double track.  An alternative is use the Double Crossover (20-210).  The #6 turnout just won't keep the spacing and it will be hard to get it back from 41mm to 33mm

With the #6, if you straighten the curve with a 249mm (20-101) you get the 33mm spacing but

1) you are going from 718mm curve into a 249mm reverse curve

2) your curved section is 3.5 to 4mm longer than the straight section. You'll have to be creative to make up for that difference. The 64mm (20-030) might be helpful here.
