I would like to know how to remove the plastics handle of Quickmill Andreja's portafilter?

Seems like all covered by plastics

May be plastic, but the center of the handle forms a hex socket. Find the right size hex wrench (big) and use that to torque the handle while holding the PF end in a padded vise.

And read that thread for other tips, like glues that may be used, etc.

Standard portafilter. Steel stud in the handle screwed into the portafilter. It is held on with thread locker and will be difficult to get off. Heat the portafilter head up with a torch. Get it real hot where the handle screws into the head. That will break down the thread locker. Grab the portafilter head with a couple oven pot holders; grab the plastic handle and twist. It should unscrew but be careful of that portafilter head. When I say hot, I mean get it real hot, the pot holders will scorch and smoke. Don't drop the portafilter head when it is that hot and do not drop it in water to cool it. Get it unscrewed and set it in a dry stainless steel sink to let it cool down slowly. If you don't have a gas torch, you can use the burner on a gas cook top which is what I do now.

Thx, I will give a try.

I finally did it. Just need the hex wrench, but need to clarm the head tight enough. No need to use heat at all.

Good Job on that! You got lucky as that looks like red loctite on the handle which is extremely difficult to remove, hence Dave's advice. But yours is done now and that's all that matters.

What are you gonna do now with it?

The hint is in the photo as well, the handle and portafilter head is sitting on a.....

There is a lot of checking on the piece of cocobolo. Be careful turning it. I would recommend cutting you square stock from the block for the handle then use thin CA (they make a thin, medium, thick super glue formula) to seal the cracks before you turn it. That will help stabilise the wood and keep it from chunking while turning. I have had pieces like that fly apart on the lathe. Getting hit with a hunk of wood spinning 2800 RPM stings.
