Zeta's Roto-casting machine build

Rotational molding, also known as rotomolding, is a molding process for creating many kinds of mostly hollow items. The info is not specific to Classic Cylon Centurions, but SURE can be helpful for them and many, many others projects. Here you'll find various threads with great info from our members for the hobby of costuming.

ROCK ON!

I thought that was going to be The A-Team theme at first, then it wasn't *disappointed*
But the pink moon boots help make up for it, a little. ;)

A major problem with the caster machine. :frak:

The belt is too soft and stretchy, the inner frame spins erratically. Often slowing down, or stopping briefly, And when it does take off, it jerks.

Conclusion... The round belt don't work. Will need to upgrade to a tighter system, such as gears and toothed belt.
:sad: :ugh: :cry: :x :?

That's a shame,

Chains instead of belts maybe?

Yep we tested the machine with two diff materials, and 2 diff mold positions, the goop built up in one area each time and was too thin in others. The rounded belt is too smooth to rotate evenly and speed seems to be a factor 4rpm takes a bit of practice. The belts seems to have almost no resistence and stretches easily around the pulley.
