Hi Justin,

Nice image, but Marc is right. This is not temperature dependant, the spilt defractions are the result of the spider vanes not being perpendicular. I have an extact for you, see the attached [the reference to the secondary being centred is for the CDK, you need the offset].

How to fix, if you are sure your offset is correct, then you need to make new holes in your front ring, to get the vanes 90 degrees to each other.

Looks great otherwise.

Steve
