@Sarah posted:Thanks, sure – these domes are specifically done for the UP O-50-6 type tank car, quite a big one, carrying 12.515 gallons. That means the radius for the dome to fit is made for a tank of 48.5mm in diameter. I love to share!

Okay, that'll be a wee bit large; can you knock that back down to 40 mm OD and all that then?
