Hi Mike,

Another thing that tends to make things difficult for filleting is having surfaces which are at very shallow angles to one another like only a 3 degree angle between them, rather than being either fully sharp or fully smooth. You've also got a fair amount of things like that in this model and so that's likely causing additional difficulties.

Very shallow angles between pieces tends to make for very small slivery and difficult to deal with juncture patches.

I'll take a look but I'm not particularly optimisitic about it, this model has a lot of things about it that make for difficulty with filleting.
