Topic: Problem with Filastruder nipple rotation

Hi folks,

Just got my filastruder working for the first time last night! I'm pretty excited. I ran it for an hour, to start purging the contaminents.

However, the nipple started to rotate. Looking at things from the front (Facing towards the cap) the nipple + cap + insulation all rotated about 45 degrees clockwise.

Should I use some clamps and try to complete the rotation? Should I rotate it back? Should I leave as is? How do I avoid this rotation in the future?

Thank you!!

I can never tighten the barrel enough that the auger won't spin it the first time it is run.  To try runs the risk of twisting the barrel.  I just accept that the barrel will probably turn.  Once it has turned 90 degrees, or close to it, I unbolt the flange, turn the whole front assembly back 90 degrees and bolt it back on.

Ah gotcha. So some torsion is normal.

It might be nice if there was a way to attach the nipple with a known amount of torque. Not sure how you could grab it with a torque wrench, but would be nice.

Re: Problem with Filastruder nipple rotation

The cutout does not have to face straight up, so don't worry about that.

The barrel rotating indicates one of three things:

1.) insufficient temperature/plastic not melted
2.) improper assembly (steps 6 and 21 ignored, uprights placed too close together, resulting in thrust load pushing on the motor)
3.) possible jam/clog in the nozzle (very rare)
