Space Station Bend

Do you need an off-the-charts bend of transparent tubing? How about a 14° 200" R (no tangents)? We received an interesting call this week. A school is preparing a model of a space station to be displayed at NASA. Our little part in this was to scale down a 12 ft...

Helix

We are privileged to participate in a helical bend for a children's museum in Baton Rouge. More later as this develops. The helix (hexagonal) has a 96" radius and composed of (CAB) cellulose acetate tubing (4.125"ID).  Model 1 and support circle.Ideas on...
