View Full Version : Another method to join styrene

Came across a video that shows joining styrene pieces together using heat from friction. Apparently there was a device made by Mattel years ago called a Spin Welder. In the video (which could use some editing) a rotary tool is used to spin a styrene rod against a junction of two panels. The heat from the friction creates a bead and joins the pieces together.

Not sure how useful this is but it may be good if you are tired of the fumes from the solvent or have run out of solvent.

Mmmm Kate Moss!! I met her once when I worked at CFOX
She's in the recent tv series called Vegas.

The girl in this video makes me think of Scooby Doo. What was her name?

It seems pretty sturdy, and would give a nice welded effect

If someone tries this method, I want to see pictures!

Meh I don't know how long she waited but I tried two small 6inch pieces and it kept braking apart easy

Actually pretty cool. I did shudder several times especially when she was trying to snap the plastic at the score line :blink: However, it can get pretty expensive as those small packs of Plastruct styrene is about 2 bucks for 3 or four pieces. Still, another possible technique for folks to try. The nerd in me has a crush on Fran rofl

The joint was already 'glued' together, but I tried this to see if it would reinforce it. Success!

Looks kinda 'weldy' too! Nice, Richard.

That looks kinda cool. Does it seem stronger?

Do you think you could use a dremel for this?

It feels stronger. It was kinda fun too. I used a Dremel. Well, it's actually a Black and Decker.

So you pretty much just put a piece of styrene in the dremel (or Black and Decker), turn it on, press it against the joint, and the weld makes its stronger? I used a soldering iron (don't ask it was my brothers) and melted two pieces of styrene together but it didn't really work. By doing it this way, is it stronger than using plastic cement?

If I am just stating the obvious, please skip this...

I can't comment on the strength, but in case it wasn't clear from the video, here's what was happening:

The spinning bit of plastic is pressed against the junction of the two pieces to be joined. Friction from the rotation causes heat to build up and some plastic to melt. The tip of the spinning piece is then advanced along the joint and fed towards the joint in order to maintain a melted area for the weld to happen.

Ok! That's whats I thought, I guess thats why my soldering iron idea didn't work....

She seemed to have gotten a little too excited there at the end when she tried breaking it apart lol :paranoid: Cool video though, always love learning new stuff. :cool:
