OO gauge 1st radius curved bridge

thingiverse

A 1st radius bridge printed from original bridge sections resized for "OO" by "Invertlogic," thank you! Two sections were used, one section curved in Matterhackers was first time used so tried few attempts before getting it right, and the second a straight section added then printed as 1 piece. You may want to add a wedge at end of bridge if your track is continuing straight. It's re-scalable, but be aware that resizing can alter the geometry of the curve; best use a 70-80mm bar as gauge on internal sides of bridge so get right width required. I created a bar in Tinkercad and moved it along internal sides of bridge to get correct width needed, settled for a 75mm "OO" gauge spacer bar which suits my needs with good clearance. If twin track bridge is needed, you may find best to strengthen the track bed as I only wanted single so scenery underneath could be visible. When/If resizing, measurements appear obscure this is why need space bar gauge.
