Is there a method for "welding" plastic binding, by which I mean melting two pieces into each other so that the seam is either non existent or at least invisible? Heat doesn't seem to do the trick, wondering about acetone, though I have it in my mind that's just for celluloid. |

The best thing to do would be to give it a try and see what happens. Do you have some scrap pieces that you can test this on? Let us know how it works. |

Stewart-MacDonald sells a jig (which you could make if you are handy) for laminating plastic bindings together, using acetone. Instructions are on the website: http://www.stewmac.com/shop/Bindings,_trim/Tools_and_supplie s_for_binding/1/Binding_Laminating_Jig/Instructions/I-4200.h tml#details If the link doesn't work you can just follow your nose at the stewmac website and find the info. Hope this helps. John |

What John said. You can also do a butt joint that way too. You can dissolve binding scraps in acetone and use the resulting white goop as a filler too. For dark bindings (tortoise), thick or medium CA works well enough as a gap filler. |

I use the same plastic melted in acetone and smear it in the middle of the join. Thinking of carpentry, I'd mitre the joint, like you would for baseboards or moulding end-to-end. For some reason, it flows better and the melted plastic doesn't have as big a job to do. |
