After heat-curing, the mandrel is removed, leaving a hollow tube.
A very economical method of clamping is that on the mandrel, which is also called expansion arbor.
A mandrel is a spindle or metal shaft around which other parts rotate.
THAT is because of the fun and love I found in the torch and glass rods and the mandrel.
After the carbon cures, the flexible bladder or silicone mandrel is pulled out through a hole in the rim opposite the valve hole; the hole is patched over afterward.
Virtually all deep-section carbon rims are made by molding the rim under pressure and heat while pulling a vacuum on the carbon layers and providing pressure against the carbon layers from the inside by either inflating a bladder inside the rim or by inserting a silicone mandrel inside that is the shape of the inside of the rim.
These are two of the eggs that I made in the same off-mandrel lampworking technique class.
I made these in an off-mandrel technique class I took at the Mest Art Center from Laurie Nessel.
Hint: be sure to rotate your mandrel so the glass can flow into place, I often have my mandrel upside down, so the glass flows next to the mandrel and rounds out on the very top.
It's gooey fun to wrap around the mandrel and just oozes where you want it to go.
