Made pig's ear out of Provincial brake van.

Noticed it derailing a lot, put it on a flat surface and one axle, perhaps one of the axleboxes is a bit off, maybe when I made the hole a bit bigger.

Any suggestions to rectify this?

Fix a pinpoint axle bearing in the hole

Is the chassis twisted? If so, might be able to tweak it a little, otherwise, consider adding a rocking axle (compensation unit) that end.

Hello, 

Enlarging the axle boxes too far on Provincial Wagon kits, even if only by a small amount, is easily done. 

The best way I would personally fix it, is by echoing what NIR said above. A brass bearing should fit nicely and give the axle somewhere correct to rest. 

The axle box may need opening up even more to accept the brass bearing, but take it nice and slow, checking now and then for fit and you should be good to go! 

Good luck! 

Nelson.
