Hingepins impossibly tight in Centro brass bulkhead

[jason-l]

Hello all. Apologies for what is, I'm sure, and elementary question.

Just started building my Centro kit, and am fitting CML's Centro brass bulkhead. Problem is the hingepin holes through it are impossibly tight and if I pressed the pin in (probably not even possible as is) they'd be stuck there forever.

Is this normal for metal-metal bulkhead-pin interfaces (I only have experience of composite/plastic bulkheads)? Should I carefully increase the brass holes' diameter or sand-down the pins?

Thanks
Jason

Try just chamfering the ends of the hing pins. I have a trishbits bulkhead which seemed impossibly tight and all I needed to do was take the edge off the tips of the hinge pins.

Thanks. I'd already tried this with no success. In the end I ran an undersize drill-bit in them, just by hand, which was enough to subtly reduce the interference fit enough to allow insertion (and future removal).
