Pretty much. The nozzle/grub is just held in place against the shoulder of the tube by gravity, a little bit of wedging by some PTFE tape (not fire cement, sorry Jay) and the force of the incoming filament.<br /><br />If the barrel isn't loaded, it is possible to smack the thing hard on a wooden block and extract the nozzle, or after use to push it back out from the other end to maintain it.<br /><br />Vik :v)Vik Olliverhttp://www.blogger.com/profile/14574212494833831824noreply@blogger.comtag:blogger.com,1999:blog-12223283.post-70543968767876399712009-05-11T16:15:00.000+01:002009-05-11T16:15:00.000+01:00@Adrian: From the picture of the nozzle in the barrel, it looks like the fire cement might be used to hold the screw in place.Jayhttp://www.blogger.com/profile/02915231145600099090noreply@blogger.comtag:blogger.com,1999:blog-12223283.post-43370078826510650792009-05-11T14:53:00.000+01:002009-05-11T14:53:00.000+01:00Brilliant work on simplifying the process. The less specialized tools needed the better. I consider myself a crafty person but have no access to a lathe.

I was fiddling with external nozzles, though - I like your solution.<br /><br />a pipe clip could apply some pressure to stop the tube pulling out.<br /><br />The 'lathe' problem is significant for those of us without access to machine shops - thanks :-)Renoirhttp://www.blogger.com/profile/10046079586632841601noreply@blogger.comtag:blogger.com,1999:blog-12223283.post-64567694693833703722009-05-11T10:26:00.000+01:002009-05-11T10:26:00.000+01:00Brilliant stuff Vik.<br /><br />So - is the nozzle 'grub screw' just held in the end by pressure and gravity?Adrian Bowyerhttp://www.blogger.com/profile/17595509188999219420noreply@blogger.com
