I had similar forebodings when I made a wheel for my kite forks
I put 2 Bantam hubs back to back and the hole in the wheel bearings for a bantam spindle was far bigger than a Scott!
then I reasoned that a bantam has a pretty poor version those pathetic things called tele forks so each leg can do its own thing while a kite fork ‘legs’ are almost braced as one component. anyway I got some drawn steel tube and some En24T bar for the spindle and made one a smooth fit in the other and a smooth fit in the bearings finally I a put a slight countersink in the inner faces of the legs and a slight chamfer on the tube ends and was very exact about spacers and tube length and bolted up the spindle.
At that point I stopped worrying about that and found something else to worry about (-:
